1 GENERAL

1.1 Field of Application

The GOLD units are designed for use in comfort ventilation applications. Depending on the variant selected, GOLD units can be utilised in buildings such as offi ce buildings, schools, day nurseries, public buildings, shops, residential buildings, etc.

GOLD units equipped with plate/coil heat exchanger (PX/CX) and separate GOLD supply air and extract air handling units (SD) can also be used for the ventilation of moderately humid buildings; however not where the humidity is continuously high, such as in indoor swimming baths.

The separate GOLD supply air and extract air handling units (SD) are designed for applications in which the supply air and extract air fl ows need to be completely separated from one another or where, due to limited available space, separate units for supply air and extract air are needed. They can also be used individually if only one of the variants is needed.

In order to fully obtain all the benefi ts the GOLD system has to offer, it is important to take the special characteristics of the air handling units into account when planning them into the project, installing, adjusting and operating them.

The air handling unit in its basic version should be installed indoors. The TBTA/TBTB accessory should be used if the air handling units are installed outdoors. If the duct accessories are installed outdoors, they must be housed in an insulated casing

(type TCxx).

Important!

Always read the safety precautions in Section 2 about what generally applies concerning risks involved and who is qualifi ed to carry out the work, and carefully follow the installation instructions that are given in each section.

The product identifi cation plates are located on the inspection side of the air handling unit and on a wall inside the fan section.

Refer to the particulars on the product identifi cation plate when you contact Swegon.

The coil heat exchangers in the one-piece units (CX) are supplied complete from the factory; including mounted the pipework package with all the necessary components. The system is normally fi lled with liquid, vented, adjusted and performance-tested prior to delivery, but can be ordered in unfi lled condition e.g. for housing improvement projects or if a liquid mixture other than

30 % ethylene glycol is required. The pipework package is available loose as an accessory for separate, size 14-80 supply air and extract air handling units (SD)

The supply air and extract air fans are of GOLD Wing+ type, an axi-centrifugal fan with backward-curved blades. The fans are direct-driven and have a motor control system for variable speed control.

1.3 Control System

The control system is microprocessor-based and is integrated into the unit. It controls and regulates the fans, heat exchanger, temperatures, airfl ows, operating times and a large number of internal and external functions as well as alarms.

1.4 Environmental Documentation

Environmental documentation with the Dismantling instructions for recycling and the Environmental Declaration are included as appendices in these instructions.

The air handling unit is designed for simple to dismantling into its natural parts. When the unit has reached the end of its useful product life, engage an approved recycling company for scrapping.

Approximately 94% of the total weight of the GOLD is can be recycled.

Swegon AB is associated with the REPA Register, no.

5560778465.

Get in touch with Swegon AB, phone: +46 (0)512-322 00, if you have any questions regarding the dismantling instructions or the air handling unit’s impact on the environment.

1.2 Mechanical Design

The GOLD is available in 8 physical sizes and for 14 airfl ow ranges.

Its sheet steel exterior is painted in a beige colour. NCS-

2005Y30R. Its door handles and the upper part of the junction hood are painted light grey. NCS 53502-B. Its interior material is mainly galvanized sheet steel with 50 mm thick intervening insulation.

The size 12-30 GOLD units with plate heat exchanger (PX) or rotary heat exchanger (RX) with air intake from above and the separate size 04-08 supply air and extract air units (SD) as well as the GOLD RX Top are equipped with pleated, class F7 fi lters. The units in other variants/sizes have class F7 supply air and extract air fi lters made of glass fi bre.

The type RECOnomic rotary heat exchanger is variable speed controlled and has a temperature effi ciency of up to 85%.

The plate heat exchangers are as standard equipped with by-pass and shut-off damper for variable and automatic control of the heat exchanger’s effi ciency on heat recovery.

1.5 Type of heat exchanger

The GOLD one-piece air handling units are supplied with either rotary heat exchanger (RX), plate heat exchanger (PX) or coil heat exchanger (CX). Coil heat exchangers are optional for the separate supply air and extract air handling units (SD).

Sections, functions, etc. that deal with one specifi c type of heat exchanger are preceded by an appropriate symbol. The three symbols used are as follows:

Rotary heat exchanger (RX)

2 SAFETY PRECAUTIONS

All staff concerned shall acquaint themselves with these instructions before beginning any work on the unit.

Any damages to the unit or its components caused by improper handling or misuse by the purchaser or the fi tter cannot be considered subject to guarantee if these instructions have not been followed correctly.

Warning

Only an authorised electrician or qualifi ed service personnel trained by Swegon shall be permitted to modify the air handling unit in conjunction with electrical installations or the wiring of external functions.

2.1 Safety Isolating Switch/Main Switch

Size 04/05, 08, 12, 14/20 and 25/30 one-piece GOLD units with rotary (RX), plate (PX) or coil (CX) heat exchanger: The safety isolating switch is located externally on the junction hood.

Size 35/40, 50/60 and 70/80 one-piece GOLD units with rotary heat exchanger (RX): The safety isolating switch is externally located on the door of the centre section of the unit.

Size 35/40 one-piece GOLD units with coil heat exchanger

(CX): The safety isolating switch is located on the left side of the electric equipment cubicle in the centre section of the unit. Size 50/60 and 70/80 air handling units:

The safety isolating switch is located in a plastic enclosure below the electrical equipment cubicle in the centre section of the unit.

Separate supply air and extract air handling units (SD): The safety isolating switch is located on the inspection side by the inspection door of the fan section.

The air handling unit shall normally be started and stopped via the hand-held micro terminal, not via the safety isolating switch.

Always switch off the safety isolating switch before servicing the unit if not otherwise specifi ed in the pertinent instructions.


2.2 Risks

Warning

Before carrying out any work, make sure that the power supply to the unit has been isolated.

Risk areas with rotating parts

Moving parts are the fan impeller, drive pulleys of the rotary heat exchanger, if fi tted, and by-pass/shut-off damper of the plate heat exchanger, if fi tted.

The lockable inspection doors serve as protection from contact with the fans and the heat exchanger. If the fan outlets aren’t connected to any duct, they must be fi tted with a protective screen (wire mesh).

Warning

The inspection doors on the fi lter/fan sections must not be opened while the unit is in operation.

Under normal operating conditions, use the stop button on the hand-held terminal to stop the air handling unit.

Wait until the fans have stopped rotating before opening the inspection door.

The air pressure inside the fi lter/fan section is positive, which means that the door can fl y open.

2.3 Safety Guards

The cover of the electric equipment cubicle serves as a safety guard in the size 04/05 and 08 one-piece air handling units with rotary heat exchanger (RX), as well as on all the other variants (PX/CX/SD). On size 12, 14/20,

25/30, 35/40, 50/60 and 70/80 one-piece air handling units with rotary heat exchanger (RX), the lockable door over the electrical equipment cubicle serves as a safety guard.

Only a qualifi ed electrician or trained service technicians shall be allowed to remove the safety guards.

Warning

The power supply to the unit shall be isolated by switching off the safety isolating switch before removing the safety guard.

As long as the air handling unit is operating, the safety guards must always be mounted, all inspection doors must be closed, and the junction hood on the top of the unit must be mounted.

2.4 Glycol

Glycol is used in the GOLD air handling units with coil heat exchanger. Never pour glycol down a drain; collect it in a receptacle and leave it at a recycling centre, petrol station, or the like. Glycol is highly dangerous to consume and can cause fatal poisoning or damage the kidneys. Contact a doctor! Avoid breathing glycol vapour in confi ned spaces. If you get glycol in your eyes, fl ush them thoroughly with water (for about 5 minutes). If glycol splashes on your skin, wash with soap and water.

3 COMMISSIONING

3.1 General

Sequence for commissioning:

1. Check that there are no foreign objects in unit, ducting system or functional sections.

2. Check that rotating heat exchangers (only GOLD RX) rotate easily. On sizes 50-80, the rotating heat exchanger must be angled slightly towards the fi lter, see diagram below.

If the angle needs adjusting, see special instructions for angle adjustment, rotating heat exchangers.

L

≈ 0,5xL

≈ 0,5xL

L

GOLD RX,, sizes 50-80: The illustration shows the factorypreset rotor inclination in a unit with Fan Arrangement 1.

The inclination must always be towards the fi lter, which means that the inclination for Fan Arrangement 2 is in the other direction.

3. Turn the safety isolating switch to the ON position (I).

4. Select the language desired, if you have not already done so. See Section 5.2 or 13.1.

5. The unit has factory settings which make it ready to use. See Section 19.2 Commissioning record.

However, in many cases, these settings need to be adjusted to suit the current installation.

Program the switch clock, operating conditions, temperatures, airfl ows and functions according to the procedures in Sections 4-15.

Select whether l/s, m3/s or m3/h shall be used as the fl ow unit.

(INSTALLATION LEVEL in the HAND-HELD MICRO TERMI-

NAL menu).

Fill out the Commissioning Record and save it in the document pocket of the unit.

In some cases it might be necessary to adjust the P-band and C-factor if the heating regulation system is oscillating or operates sluggishly. This can be done at service level and requires that you enter a special code. Get in touch with your Swegon representative.

Factory preset values (all types of GOLD):

P-band = 5.00

C-factor = 0.70 (supply air regulation)

0.20 (extract air regulation)

Normal values for the various types of air handling unit:

GOLD RX: P-band = 5.00-10.00

GOLD PX:

GOLD CX:

P-band = 10.00-20.00

P-band = 10.00-20.00

GOLD SD with coil heat exch.: P-band = 10.00-20.00

GOLD SD without coil heat exch.: P-band = 15.00-30.00

The C-Factor can in most cases be unchanged.

6. Activate, if needed, manual or auto operation (MAIN

MENU) or lock the speed of the fans (AIR ADJUSTMENT menu).

Adjust the ducting system and air devices as described in

Section 3.2.

7. Check and adjust, if required, the pressure balance in the unit as described in Section 3.3.

8. Finish off with a fi lter calibration as described in Section

6.4.2.

3.2 Adjusting the Duct System and Air Devices

In order to prevent the fans from consuming more power than necessary, it is important to keep the pressure drop in the system as low as possible.

It is also important that ducting systems and air devices are correctly adjusted to provide the comfort expected.

When adjusting air devices and the duct system installed in combination with the GOLD, it is appropriate to follow the proportionality method.

This means that the proportion between the airfl ows in branch ducts stays constant even if the airfl ow in the main ducts is changed. The same proportion applies to the air devices in the installation.

When adjusting the ducting system there is provision for locking the speed of the fans in the unit to a specifi c preset fl ow rate, see Section 6.5.

3.2.1 Adjustment Sequence

The system should be adjusted in the following order:

1. Adjust of the air devices in each branch duct.

2. Adjust the branch ducts.

3. Adjust the main ducts.

3.2.2 Adjustment Procedure

1. Set all the air devices and dampers to the fully open position.

2. Calculate the ratio of the airfl ow reading to the design airfl ow of all the air devices, branch ducts and main ducts.

The air device in every branch that has the lowest ratio should be fully open. Use this air device as an INDEX AIR

DEVICE. The same applies to branch dampers and main dampers.

When you’ve completed the adjustments, one air device in every branch, one branch damper and one main damper should consequently be fully open.

3. Start adjusting the main duct that has the highest ratio and the branch duct in the main duct that has the highest ratio. Starting from this point enables you to “press” the air in front of you toward the sections of the system that have the least air.

4. Adjust the last air device on the duct branch so that it will have the same ratio as the index device. This air device will serve as the REFERENCE AIR DEVICE. Often it is the last air device on the branch that has the lowest ratio and should be open. In this case, the same air device serves as the index device and reference device.

5. Throttle the other air devices in the branch to the same ratio as the reference device.

Note! The ratio in the reference device will change every time another air device is throttled, so in practice the ratio for the reference device can be set slightly higher. The reference device must be measured in between each air device throttled.

6. Go to the branch that had the next highest ratio and adjust the air devices there, etc.

Note! All branch dampers should be fully open until all air devices have been adjusted.

7. Throttle the branch damper that had the highest ratio to the same ratio that the branch of the lowest ratio had.

Note! Keep in mind that the index damper changes ratio; proceed as described in item 5.

8. When all branches have been adjusted, throttle the main dampers in the same manner.

Also see the example below on how to carry out adjustments.

Example on how to carry out adjustments

– Start adjusting duct branch B, since this one has the highest ratio.

– The last air device, B3, has the lowest ratio and should be fully open.

Adjust the other air devices, B1 and B2, so that these will have the same ratio as air device B3 (see item 5 above).

– Now adjust the air devices in branch duct C. Air device C4 should be fully open; throttle the others to the same ratio.

– Adjust the air devices in branch duct A. The index air device here is air device A3, which means that you fi rst throttle air device A4 (the reference device) to device A3:s ratio.

Thereafter the others are adjusted to the same ratio as air device A4.

– Throttle branch damper B to the same ratio as branch damper A, throttle branch damper C to the same ratio as branch damper A.

Check that all dampers have the same ratio.

When the adjustment has been completed, 3 air devices and one branch damper should stand fully open to obtain the lowest possible pressure in the system.

3.3 To Adjust the Pressure Balance

(applicable to air handling units with rotary heat exchanger)

3.3.1 General

The pressure in the extract airfl ow path should be slightly lower than that in the supply airfl ow path to ensure correct air leakage direction and that the purging sector in the heat exchanger will work correctly. This ensures that extract air will not be carried over to the supply air.

The pressure balance in the unit should be adjusted when the ventilation system has been fully installed, all the air devices have been adjusted and the supply air and extract air fl ows are as they should be while the air handling unit is operating normally.

Two fl ow adjustment plates are supplied with the GOLD RX Top.

The version of the air handling unit, i.e. right-hand or left-hand, is the factor that determines which of the fl ow adjustment plates you should install in the unit. Install the correct fl ow adjustment plate at its intended location inside the air handling unit. Scrap the other plate. See the illustration above.

Remove the mounting screw(s) and place the airfl ow adjustment plates in the grooves provided for accommodating them.

Refi t the mounting screw(s) and tighten it/them. See illustration above.

The pressure balance can be adjusted by blanking off holes in the fl ow adjustment plate with the plugs supplied with the unit.



3.3.2 To Ensure the Correct Leakage Direction

The adjustment plates fi tted in the extract air inlet are used for adjusting the pressure balance in the unit. The adjustment plates are supplied separately and should be fi tted in the unit by the fi tter when he connects the extract air ducting to the air handling unit. See the illustrations on the previous page.

Connect a pressure gauge to the pressure measurement tappings of the unit.

The unit has four pressure measurement tappings; the two closest to the extract air duct should be used. The blue pressure measurement tapping measures the negative pressure in the extract air section and the white pressure measurement tapping measures the negative pressure in the supply air section.

On the size 04-08 units, the pressure measurement tappings are by the junction hood and on the size 12-80 units they are inside in the centre section of the unit.

See illustration to the right.

Note that both pressure measurement tappings measure negative pressure.

MEASURED VALUES

The negative pressure in the extract air section should be greater or the same as the one in the supply air section.

If the negative pressure in the extract air section is the same or up to 20 Pa more than the negative pressure in the supply air section, then you’ve fi nished this adjustment.

DEVIATIONS

If the negative pressure in the extract air section is less than that in the supply air section, the adjustment plates must be readjusted as follows:

1. Stop the unit, open the inspection door to the extract air fi lter.

GOLD RX Top: blank off a number of holes in the fl ow adjustment plate with the plastic plugs supplied with the unit.

Other models: slightly push the fl ow adjustment plates forward (close them) in the extract air intake opening.

For full face connection (duct accessory in insulated

casing): If the commissioning plate(s) is/are completely closed and the sub-atmospheric pressure in the extract air section is still less than in the supply air section, blank off a number of holes in the commissioning plate with the plastic plugs supplied.

3. Close the inspection door and restart the unit.

4. Measure the pressures.

Repeat until the negative pressure in the extract air section is the same or up to 20 Pa higher than the negative pressure in the supply air section (0–20 Pa).

5. If the negative pressure in the extract air section is higher than 20 Pa compared to the supply air section, although the adjustment plates are completely open, the leakage and purging air fl ow will be more than anticipated. This means that the actual extract air fl ow will deviate from the preset extract airfl ow. The deviation increases with increased pressure differential.

6.3 Switch clock

Basic functions for the switch clock can be preset at INSTALLATION LEVEL under FUNCTIONS/OPERA-

TION and the values can be read and set at USER

LEVEL.

TIME/DATE

The current date and time can be set and adjusted whenever required.

The switch clock automatically takes leap years into consideration.

Automatic changeover between summer time/winter time to EU

Standard has been preset.

This changeover function can be blocked at INSTALLATION LEVEL under FUNCTIONS/OPERATION.

TIME CHANNEL

Times and days can be set when the unit is to run at high speed, low speed or be stopped.

Eight different time channels can be set. If the same in-operation times are to apply every day of the week (Mon-Sun), you need only program one time channel. Different operation times for each day of the week can be programmed by programming a time channel for each day (Mon-Fri, Sat-Sun or Mon, Tues, Wed, etc)

The time can be set as 00:00-00:00 if the deviating in-operation period is desirable for the entire 24 hours period.

YEAR CHANNEL

The year channels make it possible to set deviating in-service times for parts of the day during certain parts of the year. Eight different year channels (yearly time schedules) can be set. The year channels over-modulate the time channel during the hours of the day and the days that the year channel is active. The year channel dates indicate the dates between which the year channel shall apply and the year channel hours indicate the hours of the day between which the year channel will steer the controller to operate the rotary heat exchanger at a specifi ed speed. Other times within the year channel still apply to that time channel.

The time can be set as 00:00-00:00 if the deviating in-operation period is desirable for the entire 24 hours period.

Functions for summer night cooling, prolonged operation, etc., operate also when the year channel is active.

6.4.1 Readings

When reading of fi lter status the fi rst value shows current pressure and the second value shows current alarm limit.

6.4.2 Calibration - Filters

The fi lters should be calibrated for the fi rst time in conjunction with commissioning, when the duct system, air devices and eventual adjustment plates have been fi tted and adjusted; after that every time the fi lter media are changed.

Calibration should be activated for both the supply air and the extract air if both fi lters are changed or for only for one airfl ow direction if only one fi lter has been changed.

When fi lter calibration is enabled, the air handling unit operates in the high speed or max. speed mode (depending on the functionality selected) for approx. 3 minutes.


After the fi lters have been calibrated, a pressure rise of up to 100

Pa is permissible (=as the fi lters arrest impurities). Higher pressure will cause the fouled fi lter alarm to trip.

The alarm limit can be changed at INSTALLATION LEVEL under

ALARM SETTINGS.

The fi lter function must be activated in order to make it possible to obtain fi lter calibration and alarm functions in GOLD SD supply air and extract air handling units, see Section 8.4, Filters.

6.4.3 Calibration - Rotary Heat Exchanger

If the anti-frosting function accessory for heat exchanger is installed (see 8.5.1.1) calibration can be selected from this menu.

When calibration R-HX is activated the fans are accelerated to high speed for about 3 minutes. www.swegon.com 17

3. If a downstream heating coil is not installed, or if the

its output is not adequate, the supply air fan will be

automatically and variably downspeed-regulated to

convey air at a lower fl ow rate. (If the unit is a GOLD

SD without heat exchanger, this function can be deacti

vated).

A neutral zone can be preset, which allows a lower supply air temperature setpoint before regulation to a lower fl ow rate begins. See 8.3.4

When the supply airfl ow is regulated to a lower rate, the heat exchanger will have ”excess heat”, i.e. warm extract air, giving it capacity to maintain the supply air temperature required.

As the supply airfl ow is regulated to a lower rate, the air pressure in the premises will become negative and this will instead cause outdoor air to be sucked in through leakage spots such as doors and windows. This outdoor air will then be heated by the ordinary heating system of the premises. (Not applicable if only a GOLD SD supply air or extract air handling units are installed)

Downspeed regulation to lower the airfl ow rate occurs from the current preset fl ow (high speed or low speed), down to half of this fl ow rate. The degree of regulation to a lower rate is also limited by the min fl ow setting of the unit. When preset fl ow for low speed is near the min fl ow rate, the effect of this regulation to a lower rate will be small.

Control sequence for Extract air regulation:

1. The temperature effi ciency of the air handling unit’s heat exchanger is modulated to provide max. heat recovery. (Not applicable to GOLD SD without heat

exchanger).

2. After that, the re-heating coil, if installed, will begin to generate heat.

8.2.1.1 ERS Regulation

ERS regulation means Extract air temperature-Related

Supply air temperature regulation. This means that the temperature of the supply air is regulated in relation to the temperature of the extract air. Under normal circumstances, the supply air temperature is regulated to be a few degrees lower than the extract air temperature. In this way, the heat exchanger will provide optimal performance, and this means excellent operating economy. ERS regulation is suitable for use when there is excess heat in the premises generated, for example, by machinery, lighting or people and the supply air devices in the premises are suitable diffusing air below room temperature.


The control unit regulates the relationship between the supply air and extract air temperatures according to a factory-preset curve.

See the chart to the right.

The steps, breakpoint and EA/SA differential plotted in the curve can be changed at USER LEVEL under TEMPERA-

This is used when special needs and conditions are such that the factory preset ERS regulation 1 curve cannot provide the results required. Conditional on which settings are made, it may be necessary to install a post-heating coil.

An individually adapted curve regulates the relationship between the supply air and extract air temperature.

The setpoint displacement and summer night cooling functions can also affect the preset temperatures.

Breakpoints according to factory setting means:

If the extract air temperature is below 15 °C (X1) the setpoint for supply air temperature is constant 20 °C (Y1).

If the extract air temperature is 20 °C (X2) the supply air temperature set point will be 18 °C (Y2).

If the extract air temperature is above 22 °C (X3), the supply air temperature setpoint will be constantly 14 °C

(Y3).

8.2.1.2 Supply Air Regulation

Supply air regulation involves keeping a constant supply air temperature without consideration to the load in the premises.

This type of regulation can be used when the load and temperatures of the premises are predictable. In most cases a reheating coil needs to be installed; possibly a cooling coil as well.

The following settings can be entered at USER LEVEL under TEMPERATURE/SETTINGS:


Supply air temperature setpoint 15-40 °C 21.5 °C

Setting range for the setpoint is limited by Min. and Max. settings at INSTALLATION LEVEL under HAND TERMINAL.

8.2.1.3 Extract Air Regulation

Extract air regulation involves keeping a constant temperature in the extract air duct (premises), by regulating the supply air temperature. This provides a uniform temperature in the premises regardless of the load and this type of regulation requires the installation of a reheating coil; possibly a cooling coil as well.

The extract air temperature is measured by the temperature sensor inside the GOLD unit. If this internal temperature sensor does not give adequate representative extract air temperature readings, an external room temperature sensor can be installed and wired to terminals 40-41 on the control unit.

The following settings can be entered at USER LEVEL under TEMPERATURE/SETTINGS:

8.2.1.4 Xzone temperature control

Requires the TBLZ-2-50 zone control box. See separate instructions.

The Xzone temperature control function is designed for controlling one extra temperature zone via the ventilation system.

Xzone can be used for all types of GOLD air handling unit, and both postheating and cooling can be controlled in the extra zone.

You can activate the function; select the type of coil connected and set the required neutral zone under IQNOMIC

PLUS/Xzone.

When one of the XZONE HEATING or XZONE COOLING functions is activated, a new menu image is displayed in the hand-held micro terminal: TEMP.REG.Xzone, under

INSTALLATION – FUNCTIONS - TEMPERATURE”. The extra zone has the same settings as the ordinary menu of the air handling unit for setting the temperature regulation modes, see 8.2 Temperature regulation.

A new menu group: XZONE, is displayed between TEM-

PERATURE and FLOW/PRESSURE under SETTINGS at the user level. The selected temperature control function setpoint settings required for the extra zone can be set there.

See also the guide to the Xzone functions for more detailed information.

8.2.2 Outdoor Temperature Compensation

Temperature

Outdoor temperature compensation can be activated if the premises are abnormally subjected to the effects of seasonal cold air or hot air due to leakage through large windows, for instance.

The supply air temperature setpoint is compensated if the air handling unit is operating in the supply air regulation mode, and the extract air temperature setpoint is compensated if the air handling unit is operating in the extract air regulation mode. This function will have no effect if the unit is operating in the ERS regulation mode.

The preset temperature setpoint is infl uenced if the outdoor temperature drops below the preset X2 breakpoint

(winter compensation) and above the preset X3 breakpoint (summer compensation).

The settings are also applicable to one extra temperature zone (Xzone), if required.

See the chart to the right.

It is possible to set negative summer compensation.

8.2.3 Summer Night Cooling

The lower temperature at night is utilized to cool down the building structure. This reduces the cooling load during the fi rst hours of the day. If a cooling unit is installed, its in-operation hours will be minimized, thus offering savings. If no cooling unit is installed, a certain cooling effect will still be realized.

When summer night cooling function is activated, the unit fans operate at high speed, with a supply air setpoint of

10°C, from the preset time until the conditions necessary for stop are satisfi ed.

The extra temperature zone (Xzone), if any, will obtain the same supply air set point if summer night cooling is in operation.

Conditions to be met to start summer night cooling at the preset time:

• The extract air temperature should be higher than the preset value

• The extract air should be at least 2°C warmer than the outdoor air.

• The outdoor temperature should be above the preset value.

• Heating has not been required between 12.00–23.00 hours.

• The unit must not operate in the high speed mode or be stopped from an external source or manually from the hand-held micro terminal.

Conditions to be met to stop summer night cooling at the preset time:

• The extract air temperature drops below the preset value.

• The outdoor temperature drops below the preset value.

• Switch clock or external input calls for high speed.

• The extract air is less than 1 °C warmer than the outdoor air.

8.2.4 Intermittent Night-time Heating

The unit is utilized to heat the premises when it is normally stopped by the switch clock.

The function requires that an external room sensor is connected (control unit terminals 40-41) and that a reheating coil be installed downstream of the air handling unit. The function works best if the GOLD is equipped with an air recirculation section and shut-off dampers for the outdoor air and the exhaust air.

When the function is activated, the air handling unit detects when the room temperature drops below the preset start temperature. The unit starts with preset fl ows and the supply air temperature setpoint.

If extract air fan operation is not desirable, the extract airfl ow can be set to 0.

The damper output can be set to 0. This means that the connected dampers (such as shut-off dampers for outdoor air and extract air) will not be affected. These dampers are normally closed when the air handling unit is stopped and they also remain closed. The damper in the air recirculation section is opened at the same time, if one is installed.

Intermittent nighttime heating does not affect a possible extra temperature zone (Xzone) that regulates according to its ordinary set point, if intermittent nighttime heating is in operation.

Conditions to be met for intermittent night-time heating to start:

• The unit should operate in a time channel/switch clock stop.

• The room temperature should be below set start temperature.

Conditions to be met for intermittent night-time heating to stop:

• High speed or external/manual stop should be activated.

• Room temperature should be above the preset stop temperature.

• Alarm with preset stop priority has tripped.

If the needed, the air handling unit fans will continue to operate to cool the electric air heater although other conditions for stop have been met.)

8.2.5 Morning BOOST

The unit is utilised to heat the premises during a preset period prior to the switch-in time set on the switch clock.

The function is used if the air recirculation section is installed.

The unit starts early and uses the same operation and temperature regulation settings as it would at the regular start time.

If the extract air fan is not required to operate, the extract airfl ow can be set to 0.

Damper output can be set to be inactive. This means that connected dampers (e.g. outdoor air and exhaust air shutoff dampers) are not affected. Normally these dampers are closed when the unit is stopped and thus they remain closed. At the same time damper in the air recirculation section opens, if one is installed.

8.2.6 Setpoint Temperature Displacement

Used for changing the supply air and extract air temperature setpoints by means of an external 0-10 VDC signal

(control unit terminals 34-35). The temperature can be increased or decreased at certain times of the day by means of an external switch clock or potentiometer, for instance.

The setpoint can be infl uenced ±5 °C.

If the unit is operating in the supply air regulation mode, the supply air temperature is displaced and if the unit is operating in the extract air regulation mode, the extract air temperature is displaced.

When the unit is operating in the ERS regulation 1 mode, the difference between extract air and supply air is infl uenced. The difference cannot be less than 0 °C. The difference will decrease as the input signal increases.

If the unit is operating in the ERS regulation 2 mode, the supply air setpoint will be offset.

When the function is activated, the setpoint is offset as illustrated in the chart to the right.

Set point displacement does not affect a possible extra temperature zone (Xzone) that regulates according to its ordinary set point, if set point displacement is in operation.

8.2.7 Extra Regulation Sequence

Used for extra control functions controlled by a 0-10V signal with ordinary temperature regulation sequence.

The function can be used for utilizing existing heating or cooling sources, such as from a refrigerating plant. The function can also be used for an extra cooling or heat coil.

The out signal for the extra regulation sequence is transmitted via the same terminals on the control unit as for an air recirculation damper, if fi tted (terminals 44-45).

The maximal output signal can be limited from 100 % down to 0 %.

It is possible to combine extra control sequence with intermittent nighttime heating or Morning BOOST (requires the

IQnomic Plus accessory).

Extra regulation sequence can be selected to work in four different positions as follows:

Cooling operation

• Comfort: 0-10 V output signal sequence after the cooling function is controlled to 100 %.

• Economy: 0-10 V output signal sequence before the regular cooling function.

8.2.8 External Temperature Sensors

There are two inputs on the IQnomic for external sensors, which can be used when the internal sensor of the unit does not provide representative values.

External Extract air/Room (control unit terminals 40-41) measures the extract air temperature in a larger room or in the duct system, instead of the temperature inside the air handling unit.

External Outdoor (control unit terminals 38-39) measures the outdoor air temperature outdoors, instead of the temperature inside the air handling unit.

As an alternative, a temperature reading can be communicated to the air handling unit from a supervisory system, for instance.

8.3 Flow/Pressure

Basic functions are set at INSTALLATION LEVEL and the values are read and set at USER LEVEL.

8.3.1 Fan Regulation

The type of regulation used for the supply air fan and the extract air fan respectively can be selected individually.

8.3.1.1 Flow Regulation

Flow regulation involves operating the air handling unit to keep the preset airfl ow constant. The speed of the fans is automatically regulated to provide correct airfl ow even if the fi lters begin to become clogged, air devices are blocked, etc.

Constant airfl ow is advantageous, since the airfl ow always is exactly as it was from the beginning.

It should however be noted that everything that increases the pressure drop in the ventilation system, such as the blocking of air devices and dust accumulating in the fi lters, causes the fans to run at a higher speed. This causes higher power consumption and may also cause discomfort in the form of noise.

8.3.1.2 Pressure Regulation

The airfl ow automatically varies to provide constant pressure in the ducting. This type of regulation is also called

VAV regulation (Variable Air Volume).

Pressure regulation is used when damper operations increase the air volume in parts of the ventilation system.

The duct pressure is measured by an external in-duct pressure transducer which is wired to the BUS communication of the control unit. The setpoint setting required (separate for low speed and high speed) is entered in Pa.

The function can be limited so that the fan speed will not exceed the preset max. permissible values.

8.3.1.3 Demand Control

The airfl ow required is regulated in response to 0-10 V input signals from an external sensor, such as a carbon dioxide sensor, connected to control unit terminals 30-33.

Required setpoint (separate for low speed and high speed) is set as a percentage of the input signal.

The function can be limited so that the fl ow will not be higher or lower than the preset max. and min. permissible values respectively.

8.3.1.4 Slave Control

The fl ow is constantly regulated to be the same from the one fan as from the other fan. If one fan is pressure-controlled or demand-controlled, the other one can be controlled as a slave to generate the same airfl ow.

The performance of the fan controlled as a slave can be restricted if its maximum fl ow is set to a lower airfl ow rate.

Both fans cannot be controlled as slaves. If both are selected by mistake, the extract air fan will be forced to operate in the fl ow regulation mode.

Airfl ow

Outdoor temperature compensation of the airfl ow can be activated if it is desired to reduce the airfl ow in the wintertime.

In the fl ow regulation mode, the current airfl ow is reduced. In the pressure regulation mode, the current setpoint for pressure is reduced.

The function has no effect if the airfl ow is demand-controlled.

8.3.3 Boosting

The airfl ow is regulated between two fl ows in response to a 0-10 V DC input signal from an external source, such as a potentiometer (connected to control unit terminals

30-33).

Boosting can be used, for example, in assembly halls, where a higher rate of air change is needed under fullload conditions.

The function is activated only when the unit fans operate at high speed.

On a 0-10 V DC signal, the fans are gradually accelerated from the unit’s initial high speed setting to its initial max speed setting. On a max input 10 V DC signal, the unit fans operate at max speed.

The function must be activated separately for the supply air fan and for the extract fan.

8.6 Heating

8.6.1 Heat exchanger

8.6.1.1 Defrosting the rotary heat exchanger

In environments where the extract air can occasionally be humid, the defrosting function can be activated to protect the heat exchanger from frosting.

The function continuously monitors the condition of the heat exchanger rotor to prevent condensate from freezing in the rotor passages and clogging them.

The function requires a separate pressure transducer

(preset for heat exchanger defrosting) wired to the control unit inputs for external BUS communication and connected by hoses to the pressure measuring tappings of the unit.

See special installation instruction for the TBLZ-1-23-aa

Pressure sensor.

The pressure drop across the rotor must then be calibrated to establish a reference pressure drop for monitoring purposes. See 6.4.3 Calibration - Heat exchanger.

When the function is activated the pressure drop across the heat exchanger is continuously measured and the reading is compared with the calibration reading.

If the pressure drop exceeds the preset limit value, a defrosting sequence is carried out. This involves, decreasing the rotor speed to approx. 0.5 rpm to allow warm extract air to melt possible frost.

The defrosting sequence will be cancelled when the pressure drop has fallen to half the limit value. The defrosting operates for a max permissible period of 30 minutes.

If the pressure drop has not decreased within that max permissible period after six tries during a 24-hour period, an alarm will be initiated.

Note that the heat exchanger performs less effi ciently while defrosting is in progress and that the supply air temperature will decrease downstream of the heat exchanger.

Settings:


Defrosting Inactive/active Inactive

8.6.1.2 Exhaust air regulation, rotary heat exchanger

The exhaust air regulation function can be used whenever the exhaust air temperature is not permitted to be below a predetermined value.

The function controls the heat exchanger rotor speed

(effi ciency) in order to limit the exhaust air temperature to the required value. The function decelerates the heat exchanger rotor speed from the current level, until the exhaust air temperature drops to the preset min. permissible setting.

The following accessories are required for the preheat function:

TBLF/TCLF air heater for preheat (TBLZ-1-53-1 control system for the air heater is included) or, if an air heater other than a TBLF/TCLF is used, TBLZ-1-53-a control system for the air heater for preheat. TBLZ-1-53-1 control system for the air heater includes a TBLZ-1-30 temperature sensor and a TBIQ-2-1 IQnomic Plus-module, see separate instructions.

A regulated ramp function begins and increases the airfl ow if the temperature exceeds its setpoint and it differs

2-10°C (3°C has been factory preset) to the preset max. supply air temperature. The control reaction speed (ramp time = % fl ow increase/minute) can be set. The highest possible airfl ow is limited by the max. fl ow. For particulars on setting the max. fl ow, see Section 6.3.2.

By preheating the outdoor air, it is possible to prevent moisture precipitation in the outdoor air fi lter of the air handling unit, to reduce the risk of frosting in the heat exchanger and to eliminate the risk that the ambient temperature will drop lower than minimum permissible where the pressure sensors and frequency inverters operate.

8.7 Cooling

8.7.1 Operation

Activate the cooling function.

8.7.2 Cooling Regulation

CoolDX -Economy (without heat exchanger)

Used when the CoolDX cooling unit is connected via bus cable.

Both cooling relays of the air handling unit operate in parallel with each relay on the IQnomic plus module in the CoolDX cooling unit.

CoolDX - Comfort

Used when the CoolDX cooling unit is connected via bus cable. The heat exchanger in the GOLD unit operates in sequence with the cooling unit to even out the supply air temperature.

Applies to the COOL DX, versions A and B:

Important! Requires an extra outdoor temperature sensor.

Use the TBLZ-1-30 accessory for mounting an outdoor air temperature sensor in the ductwork upstream of the CoolDX.

Use the TBLZ-1-2 4/5 accessory for installing the outdoor air temperature sensor outdoors.

COOL DXS

For use when the COOL DXS cooling unit is connected via a bus cable. The COOL DXS operates downstream of the heat exchanger in the GOLD air handling unit.

Stepless 0-10 V DC

Used when variable cooling control is connected. The air handling unit cooling controller modulates a 0-10 V DC signal that is linear with the cooling load (control unit terminals 42-43).

Both the cooling relays of the unit operate in parallel with the signal and are energized when the cooling signal exceeds 0.5

V DC and are de-energized when the signal drops below 0.2

V DC.

The output for cooling relay 1 is connected to terminals 7-8 and for cooling relay 2 to terminals 9-10.

Stepless 10-0 V DC

Same as above, but the control signal is inverted where a 10 V output signal means a 0 % cooling load.

On/off, 1 Step

Used if cooling in one step is connected. The air handling unit’s cooling controller regulates the cooling load at 0-100

%. Cooling relays 1 and 2 are energized when the cooling load exceeds 5 % and are de-energized when the cooling load is less than 2 %.

The output contact for 0-10 V DC control signals (terminals

42-43) operates in parallel with the 0-100 % cooling demand and can be used for indicating the cooling demand, for instance.

On/off, 2 steps

Used when cooling in 2 steps is connected. The air handling unit’s cooling controller regulates the cooling load at 0-100 %.

Cooling relay 1 is energized when the cooling load exceeds 5

% and is de-energized when the cooling load is less than 2 %.

Cooling relay 2 is energized when the cooling load exceeds 55

% and is de-energized when the cooling load is less than 50

%.

The 0-10 V DC control signal output (terminals 42-43) operates in parallel with the 0-100 % cooling demand and can be used for indicating the cooling demand, for instance.

On/off, 3 Steps - Binary

Used when cooling with two inputs controlled with three binary steps is connected. The cooling controller of the unit regulates the cooling demand at 0-100 %.

On an increasing cooling load:

Cooling relay 1 is energized when the cooling load is above 5 % and is de-energised when the cooling load is between 40-70 %. Cooling relay 2 is energized when the cooling load is above 40 %. Cooling relay 1 is energized again (together with cooling relay 2) when the cooling load is above 70%.

On a decreasing cooling load:

Cooling relay 1 drops when cooling load is below 60 %, it is energized again when cooling load is below 30 % and drops again when cooling load is below 2 %. Cooling relay 2 drops when cooling load is below 30 %.

The output for 0-10 V DC control signals (terminals 42-43) operates in parallel with the 0-100 % cooling load and can be used for indicating the cooling demand, for instance.

8.7.3 Periodic Operation

Can be selected to run pumps if cooling relay 1 and/or 2 are used.

The exercising mode can be selected for “pump, pump + valve” or “valve” only (0 - 10 V output). The pumps are exercised 2 minutes per day if this is activated.

8.7.4 Regulation Speed

The required delay period between the various cooling steps can be set.

This is done so that a compressor, for instance, will have time generate required cooling capacity before the next cooling step is switched in.

This applies to changeover from step 1 to step 2 and from step 2 to step 3; and only on an increasing cooling load.

8.7.5 Outdoor Temperature Limit

Provision is available for setting an outdoor temperature-related blocking function in 3 steps. If the outdoor temperature is below each step limit, the function of the cooling relays will be blocked.

This function also restricts the 0-10 V output signal to transmission in steps.

Step 1 maximises the output signal to 2.5 V, step 2 to 5.0

V and step 3 to 7.5 V.

8.7.6 Restart Time

The time should be set in such a way that it follows the recommendations of the cooling machine supplier for the number of starts per hour.

The restart time is calculated from the time when a relay is energized to when it is allowed to be energized again.

The 0-10 V signal is delayed during the same period.

8.7.7 Cooling Min Air Flow

In order for the cooling function to operate the supply air and extract air airfl ows must be greater than their respective limit values (preset at USER LEVEL under FLOW/PRES-

SURE).

The cooling min fl ow function can be blocked by setting both fl ow limits to 0.

8.7.8 Neutral Zone

The neutral zone prevents the cooling and heating systems from counteracting each other.

Preset neutral zone is added to the setpoint for heating and the sum of these provides the setpoint for cooling.

8.7.9 Cooling BOOST

Cooling BOOST means that the supply air and extract air airfl ows are increased to convey more cooling energy to the premises.

Cooling BOOST cannot be combined with pressure regulation.

The fl ow increase takes place between current fl ow and preset max fl ow.

The function can be selected in three variants as follows:

Comfort

The cooling outputs are activated if there is a cooling load.

When the temperature exceeds its setpoint and the supply air temperature is within the preset limit, a regulated ramp function begins and increases the fl ow. The control reaction speed (ramp time = % fl ow increase/minute) can be set. The highest possible airfl ow is limited by the max. fl ow. For particulars on setting the max. fl ow, see Section

6.3.2.

Economy

Cooling BOOST Economy fi rst uses a higher airfl ow to cool the premises, before a start signal is transmitted to the cooling machines.

The function can also operate without the cooling function being activated.

On a cooling load, the fl ows are slowly increased up to preset maximum fl ow. When the fl ows are up to max and if a cooing load is still present, the output contacts for cooling are activated.

The cooling boost function requires an outdoor air temperature of at least 2 °C lower than the extract air temperature for it to be activated. Normal cooling operation is activated if the temperature difference is too small.

Sequence

The cooling BOOST Sequence is used if a cooling machine is sized for a higher than normal cooling fl ow.

If there is a cooling load, the fl ow is increased up to the preset max fl ow before the cooling function is activated.

The cooling function is delayed 1 minute after the airfl ow is increased.

The cooling boost sequence is blocked if no cooling function has been selected.

36 www.swegon.com



8.8 Humidity

Dehumidifi cation control

The dehumidifi cation function controls the moisture in the supply air duct by switching in and switching out a cooling coil and a postheating coil.

The function requires that a cooling coil be mounted upstream of a postheating coil in the supply air duct, see the example to the right.

The TBLZ-1-31-1 moisture sensor is mounted in the supply air duct and its cable is connected to the appropriate terminal on the GOLD unit.

Cooling energy is emitted to condense the moisture in the supply air fl ow, which then is heated to the desired supply air temperature. This causes a reduction in the moisture content of the supply air.

The cooling unit used must be sized so that the temperature of the supply air will be below the dew point, otherwise no condensation will arise and no dehumidifi cation will occur.

9 AUTOMATIC FUNCTIONS

9.1 General

The GOLD has a number of automatic functions. The operation of the unit is infl uenced when certain functions are activated.

9.1.1 Starting Sequence

The GOLD has a starting sequence with factory-preset time delay between every step as follows:

1. The damper relay is energized and opens the shut-off damper

(if installed).

Time delay: 30 seconds.

2. The extract air fan starts (not applicable if only GOLD SD supply air handling units are installed) and the heat exchanger is controlled to provide max. heat recovery (Not applicable to

GOLD SD units without heat exchanger). Additional heating (if installed) is activated to generate 40% of its max capacity.

Time delay: 90 seconds.

3. The supply air fan starts (not applicable if only GOLD SD extract air handling units are installed)

Time delay: 180 seconds (from the time when the extract air fan has started).

4. The temperature regulation function begins according to its regular settings.

The starting sequence prevents the extract air fan from starting if the shut-off damper is closed. By starting the extract air fan fi rst, and the heat exchanger as well, the system also avoids chilling the premises with cool supply air under cold weather conditions.

9.1.2 Cooling Recovery

Cooling energy recovery is an automatic function that helps the air handling unit utilize the relative “cooling energy” that may be present indoors if cooling is required and the outdoor temperature is high.

The heat exchanger rotates at max. speed and in this way recovers the relative cooling energy or chilliness in the extract air.

The conditions for this function to be activated are that there is a cooling demand and that the outdoor temperature is 1 °C higher than the extract air. The function is switched out when the cooling load ceases to exist or when the outdoor temperature is the same as that of the extract air.

The text COOLING RECOVERY is shown in the hand-held micro terminal.

9.1.3 Zero Point Calibration

The pressure transducer of the unit is automatically calibrated.

This calibration is carried out 3 minutes after the unit has been stopped.

The text ZERO PT CALIBR is shown in the hand-held micro terminal.

The fans cannot start while calibration is in progres s.

9.1.4 Anti-frost Monitoring Function – Air Heater for

Hot Water

The anti frost monitoring function is always active if the air heater for hot water connected has been supplied by Swegon.

The function activates a heating device that maintains 13 °C in the coil while the air handling unit is in operation and 25 °C in the coil when the unit is stopped. An alarm is initiated and the unit is stopped if the temperature sensor senses a temperature below 7 °C.

9.1.5 Additional cooling – Electric Air Heater

The fans continue to operate at min speed for 3 minutes after the air handling unit has been stopped to cool the electric heating elements if the electric air heater has been operating.

The text ADD COOLING appears in the hand-held micro terminal.

9.1.6 Reduction in output, electric air heater

A min. permissible air velocity of 1.5 m/s is required for preventing the electric heating elements from becoming overheated when they are generating full heating output.

If the air handling unit supply airfl ow drops below the value that corresponds to an air velocity of 1.5 m/s across the heat exchanger the heating output of the air heater will be automatically reduced.

The text REDUCTION IN OUTPUT appears in the hand-held micro terminal.

9.1.7 Additional running - Heat Exchanger

The rotary heat exchanger automatically continues to rotate ca 1 minute after the air handling unit has been stopped.

It takes a little time for the fans to stop rotating after a stop order has been entered in the micro terminal. This prevents the admission of cool supply air into the premises.

9.1.8 Density-corrected Airfl ow

The density of the air is different at different temperatures. This means that a specifi c volume of air will change at different air densities.

The GOLD automatically corrects this, so that correct air volume is always obtained.

The control equipment always shows the corrected airfl ow.

9.1.9 Purging Operation

Purging is an automatic function that prevents the rotary heat exchanger from standing still in the same position for a longer period when no heating is necessary.

Purging operation is activated when the unit is operating but the heat exchanger rotor is not rotating. The heat exchanger rotor then rotates for 10 seconds every 10 minutes to purge its surfaces clean of impurities.

9.1.10 Carry-over Control

Whenever the fans generate low airfl ows, the speed of the rotary heat exchanger is reduced to an appropriate level for correct purging airfl ow through the heat exchanger.

9.1.11 Calculaton of the effi ciency of the rotary heat exchanger

The effi ciency is calculated and displayed (0 – 100%).

9.1.12 Pump control for the coil heat exchanger

The pump of the pipework package starts when heat recovery is needed.

If heat recovery is not needed for more than 24 hours, the pump is exercised once a day.


www.swegon.com 41


9.1.13 Anti-frosting protection for the plate/coil heat exchanger

In cold weather, and if the extract air is humid, there is risk of frosting in plate/coil heat exchangers. The GOLD PX/CX is equipped with anti-frosting protection.

GOLD PX (plate heat exchanger)

The temperature inside the heat exchanger’s ”cold corner” and the humidity in the extract air are measured.

Taking the humidity into consideration, the control system calculates the lowest permissible temperature without risk of frosting inside the heat exchanger. The by-pass damper is then controlled to prevent the temperature from dropping below this limit.

GOLD CX (coil heat exchanger) and

GOLD SD with coil heat exchanger

The temperature of the liquid circulated to the extract air coil and the humidity in the extract air are measured.

Taking the humidity into consideration, the control system calculates the lowest permissible temperature without risk of frosting inside the coil.

The valve in the pipework package is then controlled to prevent the temperature from dropping below this limit.

12 ALARM SETTINGS

12.1 Fire Alarms

EXTERNAL FIRE ALARM

Inputs 54 and 55 are used for external fi re protection equipment.

The resetting of alarms can be selected to occur manually or automatically.

INTERNAL FIRE ALARM

The air handling unit’s internal temperature sensors serve as fi re protection thermostats. An alarm is initiated if the supply air temperature sensor registers more than 70 °C or when the extract air temperature sensor registers more than 50 °C.

If an external Extract air/Room temperature sensor is connected and activated, this works parallel with the extract air temperature sensor of the unit.

FANS IN THE EVENT OF A FIRE

The fans in the air handling unit can be used for evacuating gases, etc.

The activated function works together with the External fi re/smoke function or Internal fi re alarm.

If the air handling unit is idle, the pre-selected fans will start up regardless of whether External Stop or Manual Stop has been activated in the hand-held micro terminal.

The damper relay in the air handling unit is energized and the operating relay drops.

The dampers pre-selected for service in the event of a fi re, should be wired to the damper relay (control unit terminals 22-24) and these dampers will open.

The dampers that are meant to close in the event of a fi re, should be wired to the in-operation relay (control unit terminals 19-21) and these dampers will close.

16 MAINTENANCE

Warning

Before carrying out any work, make sure that the power supply to the unit has been isolated.

A

16.1 Filter Change

The fi lters should be changed when the fi lter alarm has been activated.

Order new fi lters from Swegon or its representative!

State the size of the GOLD unit and whether the change involves one or two air directions.

16.1.1 To remove the Filters

Pull out the handles (A) to free the fi lters from the fi lter holder.

Withdraw the fi lters.

It is advisable to clean inside the fi lter space while the fi lters are gone.

16.1.2 To fi t new fi lters

Insert the fi lters into the fi lter holder. At the same time, stretch out the fi lter bags, so that they will not get caught, hurt or become folded.

Insert the fi lters as far as possible into the unit and press lightly on the fi lter frames, so that they will fi t tightly.

Push in the handles (A) so that the fi lters are clamped in place in the fi lter holder.

Carry out a fi lter calibration as described in Section 6.4.2.

16.2 Cleaning and Inspection

16.2.1 General

Clean the interior of the air handling unit as the need arises.

Inspect the air handling unit thoroughly at the same time that you replace the fi lters or at least twice a year.

16.2.2 Filter Space

Cleaning is most appropriate when you change the fi lters.

16.2.3 Heat exchangers

Check at least twice a year whether cleaning is necessary.

The cleaning work is carried out from the fi lter space.

Rotary heat exchanger

The heat exchanger should preferably be cleaned by vacuum cleaning with a soft nozzle to prevent damaging the air passages in the rotor.

Turn the rotor by hand to enable you to vacuum clean its entire surface.

If the heat exchanger is substantially fouled, it can be blown clean with compressed air.

If necessary, the heat exchanger can be withdrawn from the unit casing and washed with degreasing solvent. Only service personnel trained by Swegon shall be permitted to use this cleaning method.

FABRIC SEAL

Lift up the fabric seal and inspect its underside. Clean if needed by brushing or vacuum cleaning.

If the fabric seal is worn or substantially fouled, it should be replaced. Do not lubricate it!

A

BELT TENSION

Replace the drive belt if it feels loose or worn and slightly slips if it meets resistance. Contact service personnel trained by

Swegon!

Plate heat exchanger

Always clean against the regular direction of airfl ow.

Cleaning shall only be done by blowing with compressed air, vacuum cleaning with a soft nozzle or wet cleaning with water and/or solvent. Before you begin cleaning, cover adjacent functional sections to protect them.

If cleaning solvent is used, do not use solvent that will corrode aluminium or copper. Swegon’s cleaning agent is recommended.

This cleaning agent is sold by Swegon Service.

Inspect the condensate drain to make sure that it isn’t clogged.

The by-pass and shut-off dampers do not require maintenance.

Coil heat exchanger

Make sure that the coils are purged of air. If a droplet eliminator is fi tted, remove it and fl ush it clean with water.

Always clean against the regular direction of airfl ow.

Cleaning shall only be done by blowing with compressed air, vacuum cleaning with a soft nozzle or wet cleaning with water and/or solvent. Before you begin cleaning, cover adjacent functional sections to protect them.

If cleaning solvent is used, do not use solvent that will corrode aluminium or copper. Swegon’s cleaning agent is recommended.

This cleaning agent is sold by Swegon Service.

While cleaning, check the content of glycol in the water and the condition of the coil for tightness. Also check that the condensate drain is not clogged.

16.2.4 Fans and Fan Space

Inspect and clean the fan impellers to remove possible dirt deposits.

Check the impeller to make sure that it is not out of balance.

Clean or brush off the fan motor. It can also be cleaned by carefully wiping it with a damp cloth that has been dipped in a solution of water and dishwashing detergent.

Clean the fan space, if needed.

16.3 Performance Checks

General performance checks should be carried out in conjunction with fi lter change or at least once a year.

It is then appropriate to compare the current performance values of the unit with the Commissioning Record. Eventual deviations should be remedied.


www.swegon.com 47


16.4 To change the pump, pipework package, GOLD CX, sizes 35-80

Before the pump can be replaced, the coils will have to be partially emptied.

An electrician or a duly qualifi ed person skilled in electrical installations is required to disconnect and connect the power supply cable to the pump.

To empty the coils:

It isn’t necessary to completely empty the system; it will be suffi cient to empty to a level just below the pump.

For the variants in which the pump is arranged above the expansion vessel, the system can be emptied from the header by the expansion vessel.

For the other variants, the venting or drain nipples on the lower coils should be used for emptying.

Open the venting valve on the upper coil as well.

To remove the old pump:

Remove the insulation material around the pump and make note of the direction of liquid fl ow.

Disconnect the electrical connections from the pump.

Remove the bolts on the pump’s fl ange connections and remove the pump.

Remove the old gaskets and clean the surfaces where they have been seated.

To mount the new pump:

Fit the new gaskets.

Check the direction of fl ow of the new pump and mount it so that the direction of liquid fl ow will be the same as before.

Tighten the bolts on the pump’s fl ange connections.

Wire the electrical connections to the pump.

To refi ll the coils:

When refi lling, fi ll with glycol of the type used in brine systems; not the type used in motor vehicles!

The glycol content is always 30% from the factory.

The total volume of glycol/water is 122 litres in size 35/40,

176 litres in size 50/60 and 231 litres in size 70/80 units.

Open the valve on the header by the expansion vessel and connect the fi lling hose.

Start the external fi lling pump and refi ll the coils. The fi lling pump should hold a pressure of approx 1 bar .

Use the venting valves to vent both the upper and lower coils.

Close the lower venting valve when liquid, free of air bubbles, fl ows out.

Close the upper venting valve when liquid, free of air bubbles, fl ows out.

Start the internal circulation pump and make sure that the direction of rotation is correct.

The green LED on the terminal box of the pump shall be lit while the pump is operating. If the red LED is lit, the pump impeller is rotating in the wrong direction.

Operate the unit for approx. 10 minutes, then vent both the upper and lower coils.

Close the fi lling valve and switch off the pump.

Remove the hoses and re-insulate the pump.

Operate the unit for approx. 1 week, then vent both the upper and lower coils again.

17 ALARMS AND FAULT TRACING

17.1 General

Alarms are indicated by an alarm text and fl ashing LED in the hand-held micro terminal.

Fire alarms and frost alarms are shown in all the menu images. Other alarms are only shown if you are in the

Main menu.

Active, but time-delayed alarms can be viewed quickly at

USER LEVEL under ALARMS. The 10 most recently initiated alarms can also be read in this menu.

A fault can be traced by examining the function or function section indicated in the alarm text.

Faults can also be traced via the READINGS menu or the

MANUAL TEST menu at Installation level.

If the fault cannot immediately be remedied:

Consider whether the air handling unit can continue to operate until the fault has been remedied. Choose to block the alarm and/or to change it from STOP to OPERA-

TION (See Section 12, Alarm settings).

17.1.1 A and B-alarms

Type A alarms transmit an alarm signal to the alarm relay A output (control unit terminals 15-16).

Type B alarms transmit an alarm signal to the alarm relay B output (control unit terminals 17-18).

From these terminals, alarms can be forwarded with different priority.

The alarm relays can be selected to have normally open or normally closed function.

17.1.2 Resetting of alarms

Alarms that require manual resetting can be reset from the hand-held micro terminal. Select RESET in the current alarm menu.

Alarms that reset themselves automatically do so as soon as the fault has been remedied.

Alarms can also be reset via a communication network.

17.1.3 Changing Alarm Settings

See Section: 12 Alarm Settings.

17.1.4 Start up after a power failure

Automatic or manual start up after a power failure can be selected.
