GB.GOLDLP.160901 1 GENERAL 1.1 Range of Application The GOLD LP is a complete air handling unit with built-in control equipment. The air handling units are designed for comfort ventilation and can be utilised in buildings such as offices, schools, day nurseries, public buildings, shops and residential buildings. The GOLD LP units are one-piece air handling units. If supplementary function sections such as dampers and air coolers are required, they must be installed in the ductwork. In order to fully obtain all the benefits the GOLD LP has to offer, it is important keep in mind the air handling unit’s special characteristics in conjunction with designing the project, installing the unit, adjusting it and operating the system. The unit must be installed indoors. Important! Always read the safety precautions in Section 2 that explain the risks involved in running the unit and designate who shall be permitted to operate and service the unit, and carefully follow the installation instructions provided in each paragraph. The product identification plate is located on the electrical equipment cubicle. Refer to the particulars on the product identification plate when you contact Swegon. 1.2 Mechanical Design The GOLD LP is available in two sizes. The external sheet metal surfaces of the unit are painted white, NCS S 0502-G, except for the back side which consists of aluminium-zinc plated sheet steel.. The inner skin is predominantly made of aluminium-zinc plated sheet steel. The casing, including the inspection panels, has a 30 mm thick intervening slab of mineral wool insulation. The GOLD LP is equipped with Class F7 bag filters. DThe type RECOnomic rotary heat exchanger is variable speed controlled and has a peak temperature efficiency of 85%. The supply air and extract air fans are direct-driven plenum fans. The fans are equipped with EC motors that provide high efficiency across the entire operating range. 1.3 Control System The IQnomic control system is microprocessor-based and is integrated into the unit. It controls and regulates the fans, heat exchanger, temperatures, airflows, 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 Product Declaration can be downloaded from our website: www. swegon.com. The air handling unit is designed in such a way that it can be dismantled into its natural parts for scrapping.

GB.GOLDLP.160901 2 SAFETY PRECAUTIONS All staff concerned must acquaint themselves with these instructions before beginning any work on the unit. Any damages to the unit or parts of it due to improper handling or misuse by the purchaser or the fitter cannot be considered subject to guarantee if these instructions have not been followed correctly. Warning Only a qualified electrician or 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 On the GOLD LP one-piece unit, the safety isolating switch is externally positioned on the electrical equipment cubicle. 2.3 Safety Guards The lockable inspection panels serve as a safety guard for the fans/heat exchanger. The cover over the power supply unit in the electric equipment cubicle serves as a safety guard for this unit. Only a qualified 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. All the inspection panels must be closed and the cover of the electrical equipment cubicle must be fastened while the air handling unit is operating. The air handling unit must normally be started and stopped from the hand-held micro terminal; not by switching the safety isolating switch on and off. Always switch off the safety isolating switch before servicing the unit if not otherwise specified in the pertinent instructions. 2.2 Risks Warning Before carrying out any work, make sure that the power supply to the air handling unit has been switched off. Risk areas with moving parts Typical moving parts are fan impellers and drive pulleys of the rotary heat exchanger. Inspection panels can only be opened using a special key, they therefore function as safety guards for fans and the heat exchanger. If the ducts are not connected to the fan outlets, the outlets must be fitted with a safety guard (wire mesh screen). Warning The inspection panels on the filter/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 panel. The air pressure inside the fan section is positive, which means that the door can fly open.

Check that there are no foreign objects in unit, ducting system or functional sections. 2. Turn the safety isolating switch to the ON position (I). 3. Select the language desired, if you have not already done so. See Section 6.2 or 14.1. 4. The unit has factory settings which make it ready to use. See Section 21.2 Commissioning record. However, in many cases, these settings need to be adjusted to suit the current installation. Program the switch clock, operating conditions, temperatures, airflows and functions according to the procedures in Sections 5-16. Select whether l/s, m3/s or m3/h shall be used as the flow unit. (INSTALLATION LEVEL in the HAND-HELD MICRO TERMINAL menu). Fill out the Commissioning Record and save it in the document pocket of the unit. 5. 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 4.2. 6. Finish off with a filter calibration as described in Section 7.4.2. 6 www.swegon.com We reserve the right to alter specifications without notice. GB.GOLDLP.160901 4.2 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 airflows in branch ducts stays constant even if the airflow 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 specific preset flow rate, see Section 6.5. 4.2.1 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. 4.2.2 Adjustment Procedure 1. Set all the air devices and dampers to the fully open position. 2. Calculate the ratio of the airflow reading to the design airflow 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 first 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.

This ensures that extract air will not be transferred to the supply air. The pressure balance in the unit should be adjusted when the ventilation system has been fully installed and the airflows discharged from all the air diffusers and registers have been adjusted, and when the supply air and extract airflows are as they should be while the air handling unit is operating normally. 4.3.2 To Ensure the Correct Leakage Direction The pressure balance in the AHU is adjusted by repositioning a commissioning plate mounted in the extract air inlet. The commissioning plate is supplied separately and should be fitted by the fitter when the extract air duct is connected. See illustration. Connect a pressure gauge to the pressure measurement tappings of the air handling unit. The AHU has four pressure measurement tappings. The two tappings closest to the extract air duct should be used. The blue pressure measurement tapping is used for measuring the negative pressure in the extract air section and the white pressure measurement tapping is used for measuring the negative pressure in the supply air section. The pressure measurement tappings are situated by the junction hood. Commissioning plate Pressure measurement tappings – leakage direction (AHU shown in the right-hand version) Note that both pressure measurement tappings are used for measuring negative pressure. MEASURED VALUES The negative pressure in the extract air section should be greater or the same as the negative pressure in the supply air section. - (blue) + (white) If the negative pressure in the extract air section is the same or up to 20 Pa greater than the negative pressure in the supply air section, then you have finished commissioning the unit. DEVIATIONS If the negative pressure in the extract air section is less than that in the supply air section, then you must carry out the following adjustment: EXTRACT AIR 2 1. Stop the air handling unit, open the inspection door to access the extract air filter. Blank off an appropriate number of holes in the commissioning plate using the plastic plugs supplied. 3. Close the inspection door and restart the AHU. 4. Measure the pressures. Repeat this procedure until the negative pressure in the extract air section is just as great or up to 20 Pa greater than the negative pressure in the supply air section (0–20 Pa). 8 www.swegon.com 5. If the negative pressure in the extract air section is greater than 20 Pa compared with the supply air section, although the commissioning plate is dismantled, the leakage and purging air flow will be greater than anticipated. This means that the actual extract air flow will deviate from the preset extract airflow. The deviation increases as the difference in pressure increases.

SWITCH CLOCK *SWITCH CLOCK* TIME/DATE TIME CHANNEL YEAR CHANNEL TIME/DATE Settings: 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. Value TIME/DATE Day Time Date 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 specified 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. 7.4 Filters (and anti-frosting function of rotary heat exchanger) There are two types of filter monitoring: Calculated filter monitoring (preset at factory) monitors the fan’s speed increase conditional on the degree of fouling in the filter. The calibration involves taking airflow and fan speed readings. An alarm is initiated when the fan speed has increased by 10% above the preset alarm limit. Filter monitoring with a pressure sensor (accessory) measures the pressure drop across the filter. The alarm limit is preset in Pa. 7.4.1 Readings When reading the filter status, the first value shows current value and the second value shows current alarm limit. 7.4.2 Calibration - Filters The filters should be calibrated for the first time in conjunction with commissioning, when the duct system, air devices and eventual adjustment plates have been fitted and adjusted; after that every time the filter media are changed. 14 www.swegon.com Setting Factory rangesetting Mon-Sun 00:00-23:59 Day/Month/Year Automatic Current Current TIME CHANNEL 1-8 Operation Time Period Low speed/High speed* High speed 00:00-23:59 00:00-00:00 Not active Not active Mon, Tues, Wed etc Mon-Fri Mon-Sun Sat-Sun YEAR CHANNEL 1-8 Operation Time Period Not active Stop/Low sp./High sp. 00:00-23:59 From Day/Month/Year To Day/Month/Year Not active 00:00-00:00 01/01/2005 01/01/2005 *) Shows Stop/Low speed/High speed if this function is selected at INSTALLATION LEVEL under FUNCTIONS/OPERATION.

After that the air heater, if installed, will begin to generate heat. 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 flow rate. A neutral zone can be preset, which allows a lower supply air temperature setpoint before regulation to a lower flow rate begins. See 8.3.4 When the supply airflow 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 airflow 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. Downspeed regulation to lower the airflow rate occurs from the current preset flow (high speed or low speed), down to half of this flow rate. The degree of regulation to a lower rate is also limited by the min flow setting of the unit. When preset flow for low speed is near the min flow rate, the effect of this regulation to a lower rate will be small. Control sequence for Extract air regulation: 1. The temperature efficiency of the air handling unit’s heat exchanger is modulated to provide max. heat recovery. 2. After that, the re-heating coil, if installed, will begin to generate heat.

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.

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.

Connect the TBLZ-1-24-2 sensor by means of the modular cable supplied, to an optional connection marked Internal BUS 1. Sensor TBLZ-1-24-2 can be used both as a room sensor and an outdoor sensor. They must therefore be addressed according to function using the function selector switch on the sensor. The function selector switch must be in Position 1 if the sensor is used as a room sensor and in Position 2 if it is used as an outdoor sensor. If the TBLZ-1-24-2 sensor is installed outdoors, it must be mounted inside an air-tight enclosure. As an alternative, a temperature reading can be communicated to the air handling via communication from e.g. a main system.

The speed of the fans is automatically regulated to provide correct airflow even if the filters begin to become clogged, air devices are blocked, etc. HUMIDITY IN/OUTPUTS IQnomic Plus ALL YEAR COMFORT OPTIMIZE Constant airflow is advantageous, since the airflow 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 filters, causes the fans to run at a higher speed. This causes higher power consumption and may also cause discomfort in the form of noise. 9.3.1.2 Pressure Regulation The airflow 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 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 flow will not be higher or lower than the preset max. and min. permissible values respectively. 9.3.1.4 Slave Control The flow 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 airflow. The performance of the fan controlled as a slave can be restricted if its maximum flow is set to a lower airflow 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 flow regulation mode.

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. *FUNCTIONS* TEMPERATURE AIR FLOW/PRESSURE FILTER OPERATION HEATING COOLING HUMIDITY IN/OUTPUTS IQnomic Plus ALL YEAR COMFORT OPTIMIZE *HEATING* HEAT EXCHANGER PRE/REHEAT HEATING BOOST 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 7.4.3 Calibration - Heat exchanger. When the function is activated the pressure drop across the heat exchanger is continuously measured and the value is compared with the calibration value. If the pressure drop exceeds the preset limit value, a defrosting sequence is implemented where the rotor speed is gradually ramped down (ramp time of max. 4 minutes) to the speed at which the pressure drop across the heat exchanger has decreased to half of the preset limit value. The rotor speed can be 0.5 rpm but not slower. During the defrosting operation, warm extract air thaws any possible ice coating. A time delay of 4 minutes gives the heat exchanger a chance to dry, before the rotor once again is ramped up (ramp time max. 4 minutes) to its ordinary speed. The max. duration of the defrosting operation is 30 minutes. If the pressure drop has not decreased within this max. duration on six occasions during a 24-hour period, an alarm is tripped.

The GOLD air handling unit’s cooling controller modulates a 0-10 V DC signal that is linear with the cooling load. Connect to the IQnomic Plus module, terminals 15-16. Both the cooling relays of the air handling unit operate in parallel with the signal and are energised when the cooling signal exceeds 0.5 V DC and are de-energised when the signal drops below 0.2 V DC. The output for Cooling Relay 1 is connected to IQnomic Plus terminals 1-2 and for Cooling Relay 2 to terminals 4-5. 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. Connect to the IQnomic Plus module, Cooling relay 1, terminals 1-2. The cooling controller of the air handling unit regulates the cooling load at 1-100%. Cooling relays 1 and 2 are energised when the cooling load exceeds 5 % and are de-energised when the cooling load is less than 2 %. The 0-10 V DC control signal output operates in parallel with the 0-100 % cooling demand and can be used for indicating the cooling demand, for instance. Connect to the IQnomic Plus module, terminals 15-16. On/off, 2 steps Used when cooling in 2 steps is connected. Connect to the IQnomic Plus module, Cooling relay 1, terminals 1-2, and Cooling relay 2, terminals 4-5. The cooling controller of the unit regulates the cooling demand at 0-100 %. Cooling relay 1 is energised when the cooling load exceeds 5 % and is de-energised when the cooling load is less than 2 %. Cooling relay 2 is energised when the cooling load exceeds 55 % and is de-energised when the cooling load is less than 50 %. The 0-10 V DC control signal output operates in parallel with the 0-100 % cooling demand and can be used for indicating the cooling demand, for instance. Connect to the IQnomic Plus module, terminals 15-16. On/off, 3 Steps - Binary Used when cooling with two inputs controlled with three binary steps is connected. Connect to the IQnomic Plus module, Cooling relay 1, terminals 1-2, and Cooling relay 2, terminals 4-5. The cooling controller of the unit regulates the cooling demand at 0-100 %.. On an increasing cooling load: Cooling relay 1 is energised when the cooling load is above 5 % and is de-energised when the cooling load is between 40-70 %. Cooling relay 2 is energised when the cooling load is above 40 %. Cooling relay 1 is energised again (together with cooling relay 2) when the cooling load is above 70%. On a decreasing cooling load: Cooling relay 1 is deenergised when cooling load is below 60 %, it is energised again when cooling load is below 30 % and is deenergised again when cooling load is below 2 %.

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. 9.7.4 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. 9.7.5 Outdoor Temperature Limit Provision is available for setting an outdoor temperaturerelated 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. 9.7.6 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 energised to when it is allowed to be energised again. The 0-10 V signal is delayed during the same period. 9.7.7 Cooling Min Air Flow In order for the cooling function to operate the supply air and extract air airflows must be greater than their respective limit values (preset at USER LEVEL under FLOW/PRESSURE). The cooling min flow function can be blocked by setting both flow limits to 0. 9.7.8 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. 9.7.9 Cooling BOOST Cooling BOOST means that the supply air and extract air airflows are increased to convey more cooling energy to the premises. Cooling BOOST cannot be combined with pressure reguWe reserve the right to alter specifications without notice. lation. The flow increase takes place between current flow and preset max flow. The function can be selected in five 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 flow. The control reaction speed (ramp time = % flow increase/minute) can be set. The highest possible airflow is limited by the max. flow. For particulars on setting the max. flow, see Section 7.2. Economy Cooling BOOST Economy first uses a higher airflow 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 flows 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 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 flow. If there is a cooling load, the flow is increased up to the preset max flow before the cooling function is activated. The cooling function is delayed 1 minute after the airflow is increased. The cooling boost sequence is blocked if no cooling function has been selected. Comfort + Economy Cooling BOOST Comfort + Economy is a combination of the two variants for increasing the airflow. If the conditions for Cooling BOOST Economy are met, the unit will begin increasing the airflow before the cooling unit starts up. If the conditions for outdoor air are not met, the flow increase will begin when the supply air temperature reaches the preset Min. permissible temperature. Economy + Sequence Cooling BOOST Economy + Sequence is a combination of the two variants for increasing the airflow. If the conditions for Cooling BOOST Economy are met, the unit will begin increasing the airflow before the cooling unit starts up. If the conditions for outdoor air are not met, the unit will begin increasing the airflow when the cooling unit starts up. www.swegon.com 33 GB.GOLDLP.160901 9.8 Humidity Dehumidification control The dehumidification 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 flow, 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.

GB.GOLDLP.160901 10 AUTOMATIC FUNCTIONS 10.1 General The GOLD has a number of automatic functions. The operation of the unit is influenced when certain functions are activated. 10.1.1 Starting Sequence The GOLD has a starting sequence with factory-preset time delay between every step as follows: 1. The damper relay is energised and opens the shut-off damper (if installed). Time delay: 30 seconds. 2. The extract air fan starts and the heat exchanger is controlled to provide max. heat recovery. Additional heating (if installed) is activated to generate 40% of its max capacity. Time delay: 90 seconds. 3. The supply air fan starts. 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 first, and the heat exchanger as well, the system also avoids chilling the premises with cool supply air under cold weather conditions. 10.1.2 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. 10.1.4 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. 10.1.5 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. 10.1.6 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. 10.1.7 Density-corrected Airflow The density of the air is different at different temperatures. This means that a specific 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 airflow. 10.1.8 Carry-over Control Whenever the fans generate low airflows, the speed of the rotary heat exchanger is reduced to an appropriate level for correct purging airflow through the heat exchanger. 10.1.9 Calculaton of the efficiency of the rotary heat exchanger The efficiency is calculated and displayed (0 – 100%). 10.1.3 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 progress.

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. ALARM PRIORITY 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 fire/smoke function or Internal fire 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 energised and the operating relay drops. The dampers pre-selected for service in the event of a fire, should be wired to the damper relay and these dampers will open. The dampers that are meant to close in the event of a fire, should be wired to the in-operation relay and these dampers will close.

Order new filters from Swegon or your nearest Swegon representative. State the type of air handling unit, and whether the change involves one or two airflow directions. N.B.! There are two types of replacement filter. One variant is for units installed in a false ceiling/horizontally, the other is for units mounted by a wall. Therefore also specify where and how the unit is located. 17.1.1 To Remove the Filters The filters can be changed from two directions, from the ordinary inspection side, but also from the extra inspection panel situated on the long sides of the unit. open the inspection panel that is simplest to access. Unfasten the filter locking piece that retains the filter cassette (located inside the air handling unit toward the inspection side). Withdraw the filters. It is advisable to clean inside the filter space while the filters are removed. 17.1.2 To Install New Filters Place the filter in the appropriate groove (located inside the unit toward the back side) and refit the filter locking piece. Check that the filter cassettes fit tightly. Close the inspection panel. Carry out a filter calibration as described in Section 7.4.2. 17.2 Cleaning and Inspection 17.2.1 General Clean the interior of the air handling unit if needed. Inspect the air handling unit when you change filters or at least twice a year. Also inspect the air handling unit fasteners that secure it to the false ceiling, wall or floor. 17.2.3 Heat Exchanger Check at least twice a year whether cleaning is necessary. Cleaning can be done from the filter space. The heat exchanger should above all be cleaned by vacuum cleaning with a soft nozzle to prevent damage to the air passages in the rotor. Turn the rotor by hand to reach everywhere. If the heat exchanger is substantially fouled, its surfaces can be blown clean with compressed air. If needed, 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 wash it in this way. 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! 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. 18.2.4 Fans and Fan Spaces Inspect and, if needed, clean the fan impellers to remove 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 and with dishwashing detergent. Clean the fan space, if needed. 17.3 Performance Checks General performance checks should be carried out in conjunction with a filter change or at least once a year. It is then appropriate to compare the current performance values of the unit with the Commissioning Record. Remedial measures should be taken to correct any possible deviations. 17.2.2 Filter Spaces The most appropriate time to clean the unit is when you change the filters. 44 www.swegon.com We reserve the right to alter specifications without notice. GB.GOLDLP.160901 18 ALARMS AND FAULT TRACING 18.1 General Alarms are indicated by an alarm text and flashing 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 OPERATION (See Section 12, Alarm settings). 18.1.1 A and B Alarms For particulars of type A alarm indication to output for Alarm Relay A (Inp. 1 and Inp. 2), see also 9.9. For particulars of type B alarm indication to output for Alarm Relay B (Inp. 1 and Inp. 2), see also 9.9. From these terminals, alarms can be forwarded with different priority. 18.1.2 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. 18.1.3 Changing Alarm Settings See Section: 13 Alarm Settings.

In case of unbalanced air flows; mean working point, supply extract shall be used. Working points with less air flow is allowed to be found outside the permissible range e.g. in case of variable air flow. Permissible operating range when the fan is controlled to operate at a lower speed. If pressure regulation is used, the airflow can be regulated to zero, however this presupposes a certain static pressure drop in the ducting (approx. 50 Pa).
