1 GENERAL
1.1 Range of Application
The COMPACT Unit and COMPACT Top are complete air handling units with built-in control equipment. The air handling units are designed for comfort ventilation and can be utilised in smaller buildings such as offices, schools, day nurseries, public buildings, shops and residential buildings.
The COMPACT Unit air handling units have duct connection spigots on their end panels whereas the COMPACT
Top units have them at the top. The type of unit can therefore be selected on the basis of the amount of space available for installing it and for arranging the ducts.
The COMPACT Unit and COMPACT Top 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 COMPACT system 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.

The external sheet metal surfaces of the unit are painted white, NCS S 0502-G, except for the rear of the COM-
PACT Top unit which consists of an aluminium-zinc plated sheet steel casing panel..
The upper section of the junction hood of the COMPACT
Unit is light grey, NCS S3502-B and the lower section is dark grey, NCS S6010-R90B.
The inner skin is predominantly made of aluminium-zinc plated sheet steel. The casing has 30 mm thick intervening mineral wool insulation; the inspection doors have 50 mm thick insulation.
The COMPACT Unit and the COMPACT Top are equipped with pleated, Class F7 filters.
The type RECOnomic rotary heat exchanger is variable speed controlled and has a temperature efficiency of up to
85%.
The supply air and extract air fans are direct-driven plug fans. The fans are equipped with EC motors that provide high efficiency across the entire operating range.
Important!

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 switch/
Main Switch
On COMPACT Unit, the safety switch is externally positioned on the junction hood.
On the COMPACT Top, the safety switch is positioned on the top front edge of the air handling unit.
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 doors 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 doors 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 door.
The air pressure inside the filter/fan section is positive, which means that the door can fly open.
2.3 Safety Guards
The lockable inspection door serves as a safety guard for fans/heat exchangers.
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.
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
(COMPACT Unit) on the top of the unit must be mounted.

GB.COMPACTUT.071201
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.

7.3 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 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.

9 FUNCTIONS
9.1 Temperature
Basic functions can be set at INSTALLATION LEVEL and values are read and set at USER LEVEL.
IMPORTANT! If you intend to substantially alter the temperature settings, you should first stop the air handling unit before doing so.
9.2 Temperature Regulation
Select ERS Regulation, Supply air regulation or Extract air regulation.
If ERS Regulation is selected, select between 1 and 2.
Control sequence for ERS regulation and Supply 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 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.

9.2.1.1 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.
ERS REGULATION 1
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-

ERS REGULATION 2
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.

9.2.1.2 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:
Value Setting range
Supply air temperature setpoint 15-40 °C
Factory setting
21.5 °C
Setting range for the setpoint is limited by Min. and Max. settings at INSTALLATION LEVEL under HAND TERMINAL.
9.2.1.3 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 COMPACT unit.
If this internal temperature sensor does not give an adequate representative extract air temperature readings, an external room temperature sensor can be installed and wired to the control unit’s connection marked “Internal
Bus-1”.
The following settings can be entered at USER LEVEL under TEMPERATURE/SETTINGS:

9.2.2 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 influenced if the outdoor temperature drops below the preset X2 breakpoint
(winter compensation) and above the preset X3 breakpoint (summer compensation).
See the chart to the right.
It is possible to set negative summer compensation.

9.2.3 Summer Night Cooling
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, its in-operation hours will be minimised, thus offering savings. If no cooling unit is installed, a certain cooling effect will still be realised.
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 satisfied.
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.

Room sensor by means of the modular cable supplied, to an optional connection marked Internal BUS 1. The capacity of the function will be best if the COMPACT is provided with a recirculation damper (not Swegon supply) and a shut-off damper for outdoor air and 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 setpoint.
If extract air fan operation is not desirable, the extract airflow 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.
At the same time, the damper in the air recirculation section, if included, will open.
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.)

9.2.5 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 airflow 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, the damper in the air recirculation section, if included, will open.

9.2.6 External Temperature Sensors
The IQnomic control unit has provision for wiring an external room sensor and/or external outdoor sensor. The sensor can be used when the internal sensor of the unit does not provide representative values.
External Extract air/Room can measure the extract air temperature in a larger room instead of the temperature inside the air handling unit.
External Outdoor measures the outdoor air temperature outdoors, instead of the temperature inside the air handling 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 alarm setting indicates how long the alarm will be delayed if communication is lost.

9.3 Flow/Pressure
Basic functions are set at INSTALLATION LEVEL and the values are read and set at USER LEVEL.
9.3.1 Fan Regulation
The type of regulation used for the supply air fan and the extract air fan respectively can be selected individually.
9.3.1.1 Flow Regulation
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, air devices are blocked, etc.
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 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.

9.3.1.3 Demand Control
The flow demand is regulated via a 0-10 V input signal from an external sensor, such as a carbon dioxide sensor that is wired to control unit terminals 35(-) and 37(+). 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.

9.6 Heating
9.6.1 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 7.4.3 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 efficiently while defrosting is in progress and that the supply air temperature will decrease downstream of the heat exchanger.

9.6.3 Heating BOOST
Heating boost means that the air handling unit, operating in the normal flow regulation mode, increases both the supply airflow and the extract airflow in order to carry more heat into the premises.
The fans are allowed to work in the range between current flows (low speed, high speed) and preset max speed flow.
The function only works if the air handling unit is operating in the extract air regulation mode. If demand control or boost is selected in combination with heating boost, the flow is controlled by the function that transmits the highest output signal to the fans.
This function cannot be combined with pressure regulation.
The flow increase starts steplessly when there is a difference of 2-10°C (3°C is factory preset) to preset max supply air temperature. When max supply air temperature has been reached, the unit runs at preset max flow (For particulars of how to set the max flow, see Section 7.2.2).

9.7 Cooling
Control of cooling units is primarily wired to Outp.1 or Outp. 2. If none of these outputs are vacant, connect the control means to the
IQnomic Plus module. The module’s function selector switch must be set to Position 6.
9.7.1 Operation
Activate the cooling function.
9.7.2 Cooling Regulation (Control)
Stepless 0-10 V DC
Used when variable cooling control is connected. The COMPACT 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 %. Cooling relay 2 drops when cooling load is below 30 %.
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.

9.7.3 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.
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/PRES-
SURE).
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 regulation.
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 cooling function is active and the temperature in the supply air drops toward the preset SA min temperature, the flow will steplessly increase.
The GOLD runs at preset max flow when the supply air temperature is same as the min. temperature.
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.

10 AUTOMATIC FUNCTIONS
10.1 General
The COMPACT has a number of automatic functions. The operation of the unit is influenced when certain functions are activated.
10.1.1 Starting Sequence
The COMPACT 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.
10.1.3 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.
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 COMPACT automatically corrects this, so that correct air volume is always obtained.
The control equipment always shows the corrected airflow.

13 ALARM SETTINGS
13.1 Fire Alarms
EXTERNAL FIRE ALARM
The Inp. 1 and Inp. 2 inputs can be used for external fire 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 fire 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 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.
FAN SPEED IN THE EVENT OF FIRE
Will be activated automatically if the fans have been activated in event of fire (see above), and make it possible to restrict the max speed of the fans.

17 MAINTENANCE
Warning
Before carrying out any work, make sure that the power supply to the unit has been isolated.
17.1 Filter Change
The filters should be changed when the filter alarm has been activated.
Order new filters from Swegon or its representative!
State the size of the air handling unit and whether the change involves one or two air directions.
17.1.1 To remove the Filters
Pull out the handles to free the filters from the filter holder.
Withdraw the filters.
It is advisable to clean inside the filter space while the filters are gone.
17.1.2 To fit new filters
Insert the filters into the filter holder.
Insert the filters as far as possible into the unit and press lightly on the filter frames, so that they will fit tightly.
Push in the handles so that the filters are clamped in place in the filter holder.
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 as the need arises.
Inspect the air handling unit thoroughly at the same time that you replace the filters or at least twice a year.
17.2.2 Filter Space
Cleaning is most appropriate when you change the filters.
17.2.3 Heat exchangers
Check at least twice a year whether cleaning is necessary.
The cleaning work is carried out from the filter space.
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!
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!
17.2.4 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.
17.3 Performance Checks
General performance checks should be carried out in conjunction with 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. Eventual deviations should be remedied.
