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.
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 situated on the top of
the air handling unit. Refer to the particulars on the product identification plate when you contact Swegon.
1.2 Mechanical Design
The COMPACT is available in one physical size and for two
airflow ranges.
The external sheet metal surfaces of the unit are painted
white, NCS S 0502-G, except for the rear of the COMPACT 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.
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.

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.140623
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.

4.3 To Adjust the Pressure Balance
Adjustment plate
4.3.1 General
The air handling unit is equipped with an adjustment
plate designed for achieving a correct air leakage direction
across the heat exchanger. This prevents the extract air
from being carried over to the supply air.
COMPACT Unit
The pressure balance in the unit should be adjusted when
the ventilation system has been fully installed and all the
air diffusers have been airflow-adjusted as well as for the
supply air and extract air flows that prevail while the air
handling unit is operating normally.

4.3.2 To Ensure the Correct Leakage Direction
The pressure balance in the unit is adjusted by means of a
adjustment plate mounted in the extract air inlet.
IMPORTANT! If you change COMPACT Unit to the lefthand version, you must move the pressure adjusting plate
(must always be situated in the extract air inlet).
Connect a pressure gauge to the pressure measurement
tappings of the unit. The COMPACT Unit has four pressure
measurement tappings. Use the two tappings nearest the
extract air duct! See illustration. The COMPACT Top has
two pressure measurement tappings. See illustration. 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.

(Unit shown in the
right-hand version)
- (blue)
+ (White)

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.
COMPACT Top
- (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’ve finished this adjustment.
DEVIATIONS
If the negative pressure in the extract air section is less
than that in the supply air section, the adjustment plate
must be readjusted as follows:
1. Stop the air handling unit, open the inspection door
and slightly close the adjustment plate in the air handling unit’s extract air inlet.
3. Close the inspection door and restart the unit.
4. Measure the pressures.
Repeat this procedure until the negative pressure in
the extract air section is the just as high or up to 20 Pa
higher than the negative pressure in the supply air section (0–20 Pa).
5. If the negative pressure in the extract air section is
higher than 20 Pa compared to the supply air section,
although the adjustment plate is completely open, the
leakage and purging air flow will be more than anticipated. This means that the actual extract air flow will
deviate from the preset extract airflow. The deviation
increases as the pressure differential increases.

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.
Important! The appearance
of the menus varies
depending on the type of air
handling unit and functions
selected.
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.
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.

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.

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

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

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.

9.2.6 Setpoint Temperature Displacement
Used for changing the supply air and extract air temperature setpoints by means of an external 0-10 VDC signal
(control unit terminals 35 (-), 37 (+)). The temperature can
be increased or decreased at certain times of the day by
means of an external switch clock or potentiometer, for
instance.
The setpoint can be influenced ±5 °C.
If the unit is operating in the supply air regulation mode,
the supply air temperature is displaced and if the unit is
operating in the extract air regulation mode, the extract
air temperature is displaced.
When the unit is operating in the ERS regulation 1 mode,
the difference between extract air and supply air is influenced. The difference cannot be less than 0 °C. The difference will decrease as the input signal increases.
If the unit is operating in the ERS regulation 2 mode, the
supply air setpoint will be offset.
When the function is activated, the setpoint is offset as
illustrated in the chart to the right.

9.2.7 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.

9.3.1 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.

SA FAN REGULATION
EA FAN REGULATION
CLEAN AIR CONTROL
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.

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.

The TBLZ-1-60 VOC sensor accessory (Volatile Organic

content of emissions/impurities in % VOC.
When an occupant emits CO2, this creates a proportional
amount of emissions/impurities which are measurable by
the VOC sensor. For an approximate translation of the %
VOC to CO2 content, see the diagram.
When the VOC sensor measures contents of emissions/
impurities that are lower than the preset value; the air
handling unit’s supply air and extract air flows are then
equivalent to the preset min. flows. When the VOC sensor
instead measures contents of emissions/impurities that are
higher than the preset value, the supply air and extract air
flows are variably increased until the preset value or max.

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

unit inputs for external BUS communication and connected by hoses to the pressure measuring tappings of the
unit.

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.

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.

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.

See preceding page for possibilities of setting.
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/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 regu38
www.swegon.com
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.

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.
10.1.4 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.
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.

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.

17 MAINTENANCE
Warning
FABRIC SEAL
Lift up the fabric seal and inspect its underside. Clean if needed
by brushing or vacuum cleaning.
Before carrying out any work, make sure that the
power supply to the unit has been isolated.
If the fabric seal is worn or substantially fouled, it should be
replaced. Do not lubricate it!
The filters should be changed when the filter alarm has been
activated.
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!
Order new filters from Swegon or its representative!
17.2.4 Fans and Fan Space
17.1 Filter Change
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.
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.
17.1.2 To fit new filters
17.3 Performance Checks
Insert the filters into the filter holder.
General performance checks should be carried out in conjunction with filter change or at least once a year.
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.
It is then appropriate to compare the current performance values
of the unit with the Commissioning Record. Eventual deviations
should be remedied.
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.

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 9.8.
For particulars of type B alarm indication to output for
Alarm Relay B (Inp. 1 and Inp. 2), see also 9.8.
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

20.3 Electrical Equipment Cubicle
The electrical equipment cubicle contains two units: the
control unit and the power unit.
On the COMPACT Unit, the control unit is positioned
behind the cover plate of the heat exchanger. This must be
dismantled to gain access.
The power unit is positioned behind the control unit.
The power unit in the COMPACT Unit is accessible after
removing the junction hood from the top of the air handling unit.
On the COMPACT Top unit, remove the cover plate by the
cable entries in the air handling unit’s extract air duct. See
the illustration.
