3. Filter Calibration

All the fi lters should be calibrated when the fans are started up for the fi rst time and when the duct system, air terminals and commissioning plates, if required, have been installed and commissioned.

After that every time fi lters are replaced. Calibration should then be activated for the fi lter or fi lters that are new. Relevant fi lters are the Supply air prefi lter, Extract air pre-fi lter, Supply air AHU fi lter, Extract air AHU fi lter, SA and EA AHU fi lter and Supply air end fi lter.

When fi lter calibration is activated, the air handling unit runs at the preset max. speed (depending on the functionality selected) for about 70 seconds.

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

Pa is permissible (as the fi lters arrest impurities) after which an alarm indicating fouled fi lter is initiated. The alarm limit can be changed under Installation, Functions, Filters.

The fi lter function must be activated (see Section 4.5) in order to make it possible to enable fi lter calibration and alarm functions of the end fi lter and pre-fi lter in GOLD SD supply air and extract air handling units.

4.1.3 Regulation mode

The regulation moden can be selected individually for the supply air or the extract air respectively.

Airflow

Flow regulation involves operating the air handling unit to keep the preset airflow constant. The speed of the fans is automatically regulated to provide correct airflow even if the filters begin to become clogged, if air diffusers become blocked, etc.

A constant airflow is advantageous, since the airflow is always at the level preset 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 filters, causes the fans to run at a higher speed. This causes higher power consumption and may also cause discomfort to the occupants such as excessive sound.

Duct pressure

The airflow automatically varies to provide constant pressure in the ducting. This type of regulation is therefore also called VAV

Regulation (Variable Air Volume).

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

The duct pressure is measured by an external in-duct pressure sensor which is connected to the control unit's BUS communication. The set point required (separate for low speed and high speed) is preset in Pa.

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

Demand

The airflow 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 18-19. The required set point is set as a percentage of the input signal or in ppm.

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

Slave

The flow is constantly regulated to the same value as 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 airflow.

The performance of the slave fan can be restricted if its maximum flow is set to a lower airflow rate.

It is not possible to control both fans as slaves. If you select one fan to operate as a slave, you lose the option to select the other fan as a slave.

4.1.5 Set point displacement

The airflow is regulated between two flows in response to an

0-10 V DC input signal from an external signal, for example a potentiometer. The TBIQ-3-2 IQlogic + module accessory is required.

Set point displacement can be used e.g. in assembly halls, where a higher rate of air change is needed under full-load conditions.

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

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

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

4.1.7 Air adjustment

The speed of the fans can be locked for up to 72 hours. When the function is activated, the speed is locked at the current speed of operation. This is practical when making airflow adjustments in the duct system and air terminals. The desired period is preset, but can be interrupted earlier by selecting Stop or by changing the time setting to 0.

4.1.8 Outdoor air compensation

Outdoor air compensation of the airflow can be activated if you want to change the airflow for specific outdoor air temperatures.

An individually adjusted curve regulates the ratio between the airflow and the outdoor air temperature. The curve has four adjustable breakpoints..

If the function is selected solely for low speed or high speed operation, the curve will regulate only one of these. The airflow for the operating case that has not been selected will then be according to the preset set point for airflow/duct pressure.

In the flow regulation mode, the current set point for airflow is changed. When pressure regulation is selected, the current set point for pressure is changed. The function has no effect if the airflow is demand-controlled.

The airflow change is expressed in the preset airflow unit and pressure in Pa.

4.1.10 Automatic operation

Density-corrected airflow

The density of the air is different at different temperatures. This means that a specific volume of air changes at various air densities. The AHU automatically corrects this, so that correct air volume is always obtained.

The control equipment always displays the corrected airflow.

Pressure balance corrected extract airflow

The extract airflow is corrected by continuously measuring the pressure balance across the rotary heat exchanger. The extract airflow is guaranteed with consideration given to the air purging and leakage air flow.

4.2 Temperature

N.B.! If the entry of new temperature settings involve large changes, you should fi rst stop the AHU before you enter the new settings.

Specifi c temperatures, such as set points, should be specifi ed in °C or °F, whereas displacements, deviations and differentials should be specifi ed in K (Kelvin).

If only GOLD SD supply air handling units are installed, they require an external room sensor for ERS, ORE and extract air regulation.

4.2.1 Status

All the relevant values can be read here. Used for performance checks.

4.2.2 Settings

ERS Regulation 1

ERS regulation refers to 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 control is suitable for use when there is surplus heat in the premises generated e.g. by machinery, lighting or people, and the premises have supply air diffusers suitable for discharging air below room temperature.

Supply air regulation

Supply air regulation involves maintaining 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 this requires the installation of an air heater for reheating, possibly an air cooler as well.

If the extract air temperature is between 20 °C (X2) and 22 °C

(X3), the supply air temperature set point is regulated from 18

°C (Y2) down to 14 °C (Y3) as shown in the curve.

When the extract air temperature is 22 °C (X4), the supply air temperature set point is regulated from 14 °C (Y3) down to 12

°C (Y4).

If the extract air temperature is over 22 °C (X4), the supply air temperature set point will constantly be 12 °C (Y4).

Extract air regulation

Extract air control involves maintaining a constant temperature in the extract air duct (the 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 an air heater for reheating; possibly a cooling coil as well.

The extract air temperature is measured by the air handling unit's internal temperature sensor. If this internal temperature sensor does not give an adequate representative extract air temperature reading, an external room temperature sensor can be installed and wired to the control unit’s communications BUS (optional

COM1-3).

4.2.3 Regulation mode

Select ERS 1, ERS 2, Supply air, Extract air, ORS or ORE temperature regulation.

Seasonal controlled temperature regulation makes it possible to have two different temperature regulation modes that alternate at preset outdoor temperatures.

Seasonal controlled temperature regulation operates with the air handling unit's internal temperature sensor, however for the best performance we recommend external outdoor temperature sensor TBLZ-1-24-3; see separate installation instructions.

Enable seasonal controlled temperature regulation and temperature regulation (ERS 1, ERS 2, Supply air, Extract air, ORS or ORE).

Set the temperature at which seasonal controlled temperature regulation shall be enabled and disabled respectively. By setting a span between the different temperatures, unwanted switching operations between the types of regulation can be avoided.

4.2.5 Set point displacement

Used for changing the supply air and extract air temperature set points by means of an external 0-10 VDC signal. For example, the temperature can be increased or decreased at certain times of the day by means of an external timer or potentiometer.

The accessory, IQlogic

+

module TBIQ-3-2, is required.

The set point can be influenced by ±5 °C.

If the AHU is operating in the supply air regulation or ORS regulation mode, the supply air temperature set point is displaced and the AHU is operating in the extract air regulation or ORE regulation mode, the extract air temperature set point is displaced.

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

If the AHU is operating in the ERS regulation 2 mode, the supply air set point will be displaced.

When the function is activated, the set point is displaced as plotted in the diagram to the right.

Set point displacement will not affect any possible extra temperature zone (Xzone) which regulates according to its ordinary set point if set point displacement is in operation.

An extract air duct temperature sensor, TBLZ-1-76, can be connected to the air handling unit’s control circuit card. See separate instructions for installation.

Up to four external room temperature and/or outdoor temperature sensors can be wired to the air handling unit’s control circuit card. The TBLZ-1-24-2 room temperature sensor or TBLZ-1-24-3 outdoor temperature sensor accessories should be used. See separate installation instructions.

The sensor can be selected to control only intermittent night heat and/or summer night cooling (the AHU is then controlled during the daytime in response to signals from the internal sensor inside the AHU).

Locate the temperature sensors at suitable places to obtain representative readings.

The air handling unit is controlled in response to a computed mean value of the temperature sensors' readings, alternatively in response to signals from the temperature sensor that measures the lowest or highest value.

As an alternative, a temperature reading can be transmitted to the air handling via communication from e.g. a main system.

The same provision is available for room sensors for the Xzone function.

4.2.12 Cooling Boost

Cooling Boost (forced cooling) means that the supply air and extract air airflows are increased to convey more cool air to the premises.

The fans are permitted to operate in the range between current flow modes or pressure (low speed, high speed) and the preset max speed. See Section 4.1.2.

The function can be selected in five variants as follows:

Comfort

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

A regulated ramp function switches in and gradually increases the airflow when there is a cooling load, and the supply air temperature is 3 K (preset at factory) higher than the preset max. supply air temperature.

Economy

Cooling Boost Economy initially uses a higher airflow to cool the premises, before a start signal is transmitted to chillers.

The function can also operate without the cooling function activated.

In the event of a cooling load, the airflows are slowly increased up to preset maximum flow. When the flows are up to max and if a cooing load is still present, the output contacts for cooling are activated.

The function requires that the outdoor air temperature is at least

2 K lower than the extract air temperature for it to be activated.

The normal cooling function is activated if the temperature difference is too small.

Sequence

The Cooling Boost Sequence is used if a chiller is sized for a higher cooling flow than normal flow.

If there is a cooling load, the flow is increased up to the preset max. flow and the cooling function is activated afterwards.

The Cooling Boost Sequence is blocked if no cooling function has been selected.

4.2.13 Intermittent night heat

The AHU is utilized for heating the premises when it is normally stopped by timer.

The function requires that an external room sensor is wired to the control unit’s communication BUS (optional COM 1-3) and that the AHU is fitted with an air heater for reheating the air. 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 flows and the supply air temperature set point. At the same time, the damper in the air recirculation section opens, if one is installed.

If recirculation is in the Off position, the extract air fan is operating and the damper relay is open. The extract airflow setting can be decreased to the air handling unit‘s min. flow.

Intermittent night heat does not affect any possible extra temperature zone (Xzone) which regulates according to its ordinary set point if Intermittent night heat is in operation.

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

• The AHU must be set to normal stop or extended normal stop.

• The room temperature must be lower than the preset start temperature.

Conditions to be met so that Intermittent night heat will stop:

• The air handling unit is running at normal low/high speed or external/manual stop has been activated.

• The room temperature exceeds the preset stop temperature.

• The alarm with preset stop priority trips.

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

4.2.14 Summer night cool

The lower temperature at night is utilised to cool down the building structure. This reduces the cooling load during the first hours of the day. If a cooling unit is installed, it will not need to be operated, thus offering savings. If no cooling unit is installed, a certain cooling effect will still be achieved.

When the function is activated, the AHU fans operate at high speed, with a supply air set point of 10 °C (factory setting) from the preset time until the conditions necessary for stop are satisfied.

If the air handling unit is stopped for a period of time, test starts can be implemented in order to check whether all conditions, except heating demand, for summer night cooling have been met. If the conditions have been met, summer night cooling can be run. The start and stop dates of the period during which the air handling unit will be stopped can be preset.

The set point for flow or pressure on the supply air and extract air can be set. This then means that any outdoor compensation does not affect summer night cooling.

An extra temperature zone (Xzone), if required, obtains the same supply air set point if Summer night cool is in operation.

Conditions that must be met for Summer night cool to start at the preset time:

• The time is between the preset start time and stop time.

• The outdoor air temperature shall be higher than the preset value.

• The extract air temperature shall be higher than the preset value.

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

• Heating has not been required between 12.00 and 23.59 hours.*

• The air handling unit shall be running at low speed or be in the normal stop operating mode.

• Intermittent night heat has not been active during the day.

Conditions that must be met for Summer night cool to stop:

• The time is not between the preset start time and stop time.

• The extract air temperature drops below the preset value.

• The outdoor temperature drops below the preset value.

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

• The air handling unit is running at normal high speed or external/manual stop has been activated.

The function starts once per preset time period.

4.3 Time and schedule

The built-in timer enables you to control the AHU's operating mode/time. Certain other oversteering functions such as external timer, communication, etc. affect the preset operating modes.

There are fi ve different operating modes:

Total stop = The AHU is completely stopped, no internal automatic functions or external control commands can start the AHU.

Normal Stop = The AHU has stopped, however all the internal and external automatic functions oversteer the stop.

Extended Normal Stop = The AHU has stopped, however all the internal and external automatic functions, with exception of

Summer night cool, oversteer the stop.

Low speed = The AHU is running at the preset low speed setting.

High speed = The AHU is running at the preset high speed setting.

4.3.1 Time and date

The current date and time can be set and adjusted if needed. The timer automatically takes leap years into consideration.

The relevant region and city can be selected, summer time/winter time changover will then be managed automatically.

Time source can be set to manual or via SNTP (requires connection to network) and BACnet. The time format and date format can be set.

4.3.2 Schedule settings

The relevant operating mode can be read under Schedule settings. Here you can also set a preselected operating mode, in which the air handling unit always operates during non-programmed time, under Day schedule and Exceptions schedule.

This setting (start and stop date not activated) is used most often and covers the majority of needs.

When the start and stop date is activated, this means that during the preset period (date) preset time applies during the day schedule and the exceptions schedule, and at all other times the

AHU runs in the preselected operating mode.

The resetting of internal fi re alarms as well as the external fi re alarms 1 and 2 can be individually selected to manual or automatic.

After cool

The After cool function for electric air heaters can be individually activated, for internal fi re alarms as well as external fi re alarms 1 and 2.

Fan operation at fi re alarm

The fans of the air handling unit can be used for evacuating smoke, etc. It is possible to individually select the type of fan operation for each separate fi re alarm.

If the AHU is idle, the fans selected start up (10-100%), irrespective of whether stop (all types) is activated.

The AHU's damper relay is energized and the AHU's operation relay is de-energized. The damper that should be open in event of fi re, shall be connected to the damper relay (control unit terminals 28-30). The damper that should be closed in event of fi re, shall be connected to the operation relay (terminals 26-27 of the control unit, potential-free contact).

4.10.5 Automatic functions

Start up sequence

The air handling unit has a start up sequence with a factorypreset time delay between each step as follows:

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

(if installed). The heat exchanger is controlled to max. heat recovery (not the GOLD SD without heat exchanger). The valve for reheating opens to 40% (if installed)

Time delay: 30 seconds.

2. The extract air fan starts in the current operating mode (not for ventilation systems with GOLD SD supply air handling unit only)

Time delay: 60 seconds.

3. The supply air fan starts (not for ventilation systems with

GOLD SD extract air handling unit only)

Time delay: 30 seconds.

4. The reheating function is ramped up or down depending on the heating load. Ramp time: 180 seconds. After that the heat exchanger is ramped up or down depending on the heating load. Ramp time: 180 seconds.

The entire start up sequence can be followed in the dashboard image.

The start up sequence prevents the extract air fan from starting up if the shut-off damper is closed. By first starting up the extract air fan and the heat exchanger, you can avoid chilling the premises with supply air on a start up under cold weather conditions.

Zero point calibration

The pressure sensor of the AHU is automatically calibrated. The calibration process takes about 70 seconds after the AHU has stopped (a notification is shown if the AHU has not stopped).

The zero point calibration text is displayed in the hand-held terminal. The fans cannot start while calibration is in progress.

4.11.3 Extra regulation sequences 1 and 2

Used for extra regulation functions controlled by a 0-10 V (10-0

V) signal with ordinary temperature regulation sequence.

The function can be used for utilising existing heating or cooling sources, such as from a chiller. The function can also be used for an extra air heater or air cooler.

It can also be used for controlling dampers for recirculation, if required. In these cases, an inverted 10-0 V output is used.

Recirculation control is used for the TBBD mixing section (GOLD

SD only) The 10-0 V inverted output should be in the On position.

The maximum output signal can be limited from 100% down to

0 %.

The output signal of the extra regulation sequence is controlled from the TBIQ-3-2 IQlogic + lation instructions.

module accessory, see separate instal-

When the SMART Link DX function is selected, the extra regulation sequence is automatically activated. The extra regulation sequence cannot then be used for any other functionality. An

IQlogic+ module is not required (alarm for missing module is blocked).

The extra regulation sequence makes it possible to control two air heaters at the same time in the following combinations: water - electricity, water - water, electricity - electricity (Season heat, see also Section 4.11.7). The air heater for hot water is available without or without frost guard function.

When the output of the first air heater is not sufficient, the second is automatically brought into the sequence.

A start-up sequence, frost guard function, pump control, postcooling for electric air heater and other functionality are available.

For the start-up sequence, frost guard function, periodic operation and post-cooling, the same settings are used as for regular reheating.

4.11.8 Automatic functions

Frost guard function, air heater for water

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

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

Capacity reduction of the electric air heater

Only in combination with Swegon's electric air heater.

A min. permissible air velocity of 2.0 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 airflow drops below the value that corresponds to an air velocity of 2.0 m/s across the heat exchanger, the heating output of the air heater will be automatically reduced.

4.13.4 Defrost

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 it from becoming clogged due to condensate that has frozen inside the exchanger.

The function requires a separate pressure sensor (preset for heat exchanger defrosting) wired to the control unit inputs for external BUS communication and connected to the AHU pressure measurement tappings. 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.

Calibration is put into effect by setting Calibration to the On position.

When the defrosting 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 implemented in which the rotor speed is gradually ramped down

(ramp time max. 4 minutes) to the speed at which the pressure drop across the heat exchanger decreases to half of the preset limit value. The lowest permissible speed of the rotor is 0.5 rpm.

During the defrosting process, the warm extract air thaws any possible ice that has formed on surfaces. A delay time of 4 minutes gives the heat exchanger time to dry, before the rotor once again is ramped up (ramp time max. 4 minutes) to its ordinary speed.

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 efficiently while defrosting is in progress and that the supply air temperature will also drop downstream of the heat exchanger.

4.13.6 Automatic functions

GOLD RX (rotary heat exchanger)

Purging function

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 AHU 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.

Calculation of the efficiency

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

Calculation of recovered energy

Recovered sensible energy is calculated and the values are displayed (instantaneous and accumulated).

Cooling recovery

Cooling recovery is an automatic function that helps the air handling unit on a cooling load and high outdoor air temperature to utilize the relative "cooling energy" that can be indoors. 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 stops when the cooling load ceases to exist or when the outdoor temperature is the same as that of the extract air.

Overtime heat exchanger operation

If the AHU stops, the heat exchanger automatically continues to recover heat for about 1 minute.

It takes a little time for the fans to stop rotating after a stop has been ordered and this prevents the supply air from chilling the premises.

GOLD CX/SD (coil heat exchanger)

Pump control, 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.

Anti-frost protection

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

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 regulated to prevent the circulated liquid from dropping below this temperature.

GOLD PX (plate heat exchanger)

In cold weather, and when the extract air is humid, there is risk of frosting in the plate heat exchanger. The GOLD PX is therefore equipped with anti-frost protection.

Anti-frost protection, standard

The pressure drop across the heat exchanger and the outdoor air temperature are measured.

With consideration given to the pressure drop across the heat exchanger and the outdoor air temperature, the control system regulates dampers for bypass and heat exchanger (interlinked) in order to prevent the formation of frost.

RECOfrost anti-frost protection

The pressure drop across the heat exchanger, extract air temperature, moisture content in the extract air and outdoor air temperature are measured.

With consideration given to the pressure drop across the heat exchanger, the extract air temperature, the moisture content in the extract air and the outdoor air temperature, the control system individually regulates dampers for bypass and the heat exchanger for section-by-section defrosting without the formation of frost.

The function requires the TBIQ-3-1 IQlogic Plus module accessory and one TBLZ-31-1 humidity sensor accessories (for supply air regulation) or two TBLZ-31-1/2 humidity sensor accessories

(for extract air regulation), see separate installation instructions.

Install the humidity sensors in the extract air duct and the supply air duct respectively. See drawing!

The function keeps the humidity level constant in the extract air duct (the premises) by regulating the humidity in the supply air.

In order to prevent the humidity in the supply air from being too high, it is restricted to a maximum limit.

Alternatively the humidity in the supply air duct can be kept constant by selecting a regulating humidity sensor in the supply air.

4.15.3 Dehumidifying

The function is intended for dehumidifying the supply air in order to prevent condensation in the supply air duct or in connected air conditioning products.

The dehumidification regulation function controls the humidity in the supply air duct or the extract air duct by means of an air cooler and an air heater for reheating.

The function requires that an air cooler be mounted upstream of the air heater in the supply air duct. See the example to the right.

If control of the humidity in the supply air duct is required, install a TBLZ-1-31-1 humidity sensor in the supply air duct. If control of the humidity in the extract air duct is required, install a TBLZ-

1-31-2 humidity sensor in the extract air duct and a TBLZ-1-31-1 humidity sensor in the supply air duct. Connect the sensor to the

AHU. See separate installation instructions.

Cooling energy is emitted to condense the moisture in the supply airflow, 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 dehumidification will occur.

function is designed for ensuring the correct air quality or air temperature, by means of recirculating extract air and minimizing the infl ow of outdoor air.

The function can be used in ventilation systems in which recirculated air intermixture is acceptable.

The function presupposes that the outdoor air damper and the damper in the air recirculation section are equipped with modulating damper actuators.

Lower outdoor air and exhaust air fl ows as well as lower extract air fan speed enable the unit to consume less power. A separate air quality sensor continuously measures the air quality of the ventilation system.

The pressure drop across the rotor must then be calibrated to establish a reference pressure drop for the function. Calibration is put into effect by setting Calibration to the On position.

4.18 MIRU Control

Up to ten power roof ventilators with MIRU Control equipment can be connected to one GOLD air handling unit by means of bus communication.

If one or several power roof ventilator(s) is/are stopped via the control panel on the corresponding MIRU Control, the power roof ventilator(s) cannot be started via the GOLD unit hand-held terminal.

The settings in the hand-held micro terminal of the GOLD unit override the settings in the MIRU Control’s control panel.

It is possible in the hand-held micro terminal to select whether the power roof ventilator should be controlled in parallel with the GOLD unit, and whether it should follow the low-speed/ high-speed operating modes of the air handling unit.

The balanced ventilation function can be used if the power roof ventilators are used for variable fl ow. It is then possible to select which power roof ventilator(s) is/are to be included in the function.

In the case of balanced extract air, all the airfl ows of the activated power roof ventilators are added together. The extract airfl ow in the GOLD unit is decreased by the corresponding volume. In this way the supply airfl ow will be the same as the total extract airfl ow and balanced ventilation will be achieved inside the building.

In the case of balanced supply air, all the airfl ows of the activated power roof ventilators are added together. The supply airfl ow in the GOLD unit is increased by the corresponding volume. In this way the supply airfl ow will be the same as the total extract airfl ow and balanced ventilation will be achieved inside the building.

The function presupposes that pressure sensors for fl ow measurement and possible pressure regulation are connected to

MIRO Control.

All the time channels available in MIRU Control can be set separately for each connected power roof ventilator via the GOLD unit hand-held micro terminal. For a description of the function, see the separate Guide to the MIRU Control Functions.

Depending on the function selected in MIRU Control, it is possible to set the desired set point for pressure or fl ow, low speed and high speed, in the GOLD unit hand-held micro terminal.

For a description of the function, see the separate Guide to the

MIRU Control Functions.

4.24 Manual test

NB! Manual test running can cause indoor comfort problems. There is also risk of overloading the system. The responsibility for discomfort and overload rests totally on the person who activates the function.

When you enter manual test, you must select a safe mode or live mode. Safe mode involves stopping the AHU and being able to run each installed function separately or together. In the safe mode the heat exchanger is oversteered in relation to the fan speed. Live mode involves permitting the AHU to continue to operate in the normal operating mode and installed functions can be infl uenced manually. In this live mode the heat exchanger is not oversteered in relation to the fan speed.

Manual test operation can take place for testing the inputs and outputs, fans and heat exchanger, etc.

Used for installation or troubleshooting to test that wired connections and functions operate correctly.

Certain alarms, functions and normal control modes will be blocked while manual testing is in progress.

On a return to the other image groups, the controller resumes normal operation and all settings for manual testing will be terminated.

Each image indicates which functions can be test run.
