1 GENERAL
1.1 Field of Application
The COMPACT Air and COMPACT Heat units are complete
air handling units that can be installed directly in the room
to be ventilated. The ducts for outdoor air and exhaust air
should be connected to the top of the unit and should be
arranged to lead out through the wall. Other than that,
you need only connect the unit to the mains electric supply.
The installation work can be carried out very quickly and
easily and if the task of cutting openings through the wall
is not complicated, the unit can be operational in just a
few hours. It is also simple to relocate the air handling
unit if the nature of the activities conducted in the room
changes.
The ventilation is very effective thanks to the displacement
air distribution method used. The built-in control equipment has several functions for economic operation.
The COMPACT Air and COMPACT Heat units are designed
for comfort ventilation and can be used in classrooms, day
nurseries, conference halls, smaller offi ces, workrooms,
shops, restaurants and similar public premises.
The difference between the COMPACT Air and the COMPACT Heat units is that the COMPACT Heat units can also
be used for heating.
It is important keep all the special characteristics of the
air handling units in mind when planning them into the
project, installing, adjusting and operating them to fully
obtain all the benefi ts the COMPACT system has to offer.
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 identifi cation plates are located inside the
room unit and on the unit’s rear side. See Sections 1.5.1
and 1.5.2 respectively. Refer to the particulars on the
product identifi cation plate when you contact Swegon.
1.2 Mechanical Design
The COMPACT is available in one physical size and for two
airfl ow ranges.
Its sheet steel exterior is painted white, NCS S 0502-G.
The decorative strips and cover plate around the control
display are 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 Air and the COMPACT Heat are equipped
with pleated, Class F7 fi lters.
The type RECOnomic rotary heat exchanger is variable
speed controlled and has a peak temperature effi ciency of
85%.
The supply air and extract air fans are direct-driven plug
fans. The fans are equipped with EC motors that provide
high effi ciency 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, airfl ows, operating times
and a large number of internal and external functions as
well as alarms.
1.4 Environmental Documentation
Environmental Documentation with the Dismantling
Instructions for recycling and the Environmental Declaration can be downloaded from our home page: wwww.

3.5 To Install the Air Recirculation Section/
Louvre Damper
(applies to COMPACT Heat only)
The room temperature sensor supplied with the unit must
be mounted, see special instructions for the TBLZ-1-24-2
room sensor.
The air recirculation section and louvre damper are supplied loose.
The damper actuator for the air recirculation section is
supplied resting on the extract air intake mesh on top of
the unit. This part must be mounted on the air recirculation section’s damper spindle as follows:
1. Remove the damper actuator from the mesh of the extract
air intake. It is advisable to mount the damper
actuator while the air recirculation section is at fl oor level
before the former is mounted.
2. Disconnect the electric quick connector on the damper
actuator.
3. Secure the mounting rail by means of the screws provided,
in the redrilled holes on the air recirculation section. See
illustration.
3. Mount the damper actuator with the damper blade in the
outdoor air position, that is: the damper blade must be
located against the grille. See illustration.
4. Tighten the screws holding the damper actuator with the
clamp on the damper spindle. Set the actuating direction
according to the direction arrow towards 0. See illustration.
5. Mount the air recirculation section on the top side of the air
handling unit for outdoor air and connect the electric quick
connector.
6. Fit the louvre damper on the top side of the air handling
unit for exhaust air.
3.6 Duct Connection
Connect 250 mm dia. spiral ducts to the outdoor air and
exhaust air connections on the top side of the air handling
unit.
Run the ducts through the external wall and have the duct
end edge-to-edge with the façade of the building if Swegon’s external wall hood is used.
The ducts can also be run through the ceiling (the ducts
for the COMPACT Heat cannot be run straight up from
the air handling unit. However this makes more complicated modifi cations necessary and among others places
greater demands on sealing around the arrangement to
achieve air tightness.
The ducts must be insulated with at least 30 mm thick
insulation and be provided with a damp-proof outer layer.
3.3 Location
To achieve optimal operating economy it is important to
design the duct system with as low a pressure drop as possible. Therefore the designer should focus on arranging
the duct runs as short as possible so that there will not be
more duct bends than necessary. The duct connections on
the Compact Air/Heat units are arranged to enable ducts
to be run in any direction without being in the way of one
another.
The design of the hoods, grilles, etc. for outdoor air/exhaust air are also important. The specially constructed
exterior wall hood for the Compact Air/Heat units is designed in such a way that minimizes pressure losses.
Examples of alternative locations of the Compact Air/Heat
unit in a room are shown below.
Important! The air handling unit should be located
at least 400 mm on either side from a wall to avoid
acoustic problems. See the illustration below.
For the sake of comfort, the nearest workplace should be
1 metre from the unit. However note that at least 1,200
mm open space is required in order to be able to open the
inspection door.
In the case of a COMPACT Heat unit, make sure that you
provide open space in front of the air handling unit to enable long throw lengths when the unit is operating in the
BOOSTER mode (fl ow Boost).
3.4 To Fit the Kick-protection Base
Secure the 6 screws supplied halfway into the tapped
holes on the base beam of the air handling unit.
Then fi t the side plates of the kick protection base (the
two short plates) by pushing the keyhole fasteners over
the screws from the front side of the unit. Now the side
plate should hang loosely on the screws.
Fit the front side of the kick protection plate (the long
plate) on the two screws on the front side. Now the front
plate should hang loosely on the screws.
Adjust the position of the plates and tighten the screws.
Fasten the cover plugs, supplied, in the holes over the
screws.
Important! If the unit is to be installed with its right-hand
or left-hand side near a wall (min. of 400 mm), the base
plate that is to face this way should be fi tted before the
unit is positioned at its fi nal location.

3.7 Exterior Wall Hood
The CACZ-1-03 External wall hood accessory is specially
designed for low pressure drop and for preventing shortcircuiting between the outdoor air and the exhaust air.
The standard hood is painted grey black, NCS 8502-B. See
special instructions.
3.8 Existing Ventilation
The existing ventilation in the room for supply air and
extract air should be blanked off or sealed. This is an
important prerequisite for satisfactory ventilation and heat
recovery.
3.9 Serving More than One Room
The COMPACT Air units are designed for installation and
connection according the instructions in Sections 3.3, 3.6
and 3.7.
Swegon recommends this procedure.
Nevertheless it is possible to completely or partially take
extract air from adjacent rooms or also to ventilate a space
other than the room where the air handling unit is standing.
The problems, which one must observe in this case, are
specifi ed below. Always engage the services of a professional in this fi eld.
3.9.1 Extract Air Intake
If the extract air is completely or partially taken from an
adjacent room, note that the duct pressure drop must not
exceed available pressure.
Also note that the supply air temperature is regulated in
relation to the extract air temperature. If the extract air
comes from another room with a different temperature,
the temperature of the supply air may cause short-circuit
airfl ows or give rise to draught problems. Pay special attention to where the extract air sensor is located.
3.9.2 Transfer Air
Transfer air grilles to adjacent rooms have a strong infl uence on the system’s performance.
Air transfer grilles positioned low, cause the transfer of
”unused” air to adjacent rooms and impair the ventilation
performance in the room where the unit is installed.
Air transfer grilles positioned high involve the risk that
”used” air will be transferred to adjacent rooms. Ventilation is however not impaired in the room where the unit is
installed.
Important! If the doors are open, the adjacent room will
also be ventilated due to the displacing air supply.
3.10 Connection to the Electric Power Grid
The COMPACT air handling unit is supplied with a power
cable with mains plug, from the factory.
COMPACT Air
Cable: 3 x 1.5 mm2. Mains plug, 10 AT, single-phase 230V.
COMPACT Heat
Cable: 5 x 2.5 mm2. Mains plug, 5-wire Perilex, 16 AT,
3-phase 400V.
Important! The power supply connection to the COMPACT Heat unit is not of an electrical safety design that
prevents children from inserting objects into the socket. It
is recommended that it be positioned 2 metres above the
fl oor above the air handling unit by the duct connections
for instance.
If the air handling unit is instead to be connected with a
fi xed extension, an external main switch must be fi tted.
3.11 To Connect External Cables
The electrical cubicle in the COMPACT Air and the COMPACT Heat units is located by the heat exchanger. When
access to the control unit is required, the safety guard
in front of the heat exchanger must fi rst be dismantled.
When access to the power unit is required, the cover plate
in the unit’s extract air duct must fi rst be dismantled.
Cables from external sources can be run into the air handling unit through the rubber diaphragm by the extract air
intake, located on the top of the unit.
The external cables can be extended in the existing cable
protection together with the power supply cable in the
extract air duct of the unit. Insert the cable in the opening
in the end of the cable protection or press it in between
the cable protection and the insulation.
Cables can be run in to the electric cubicle according to
appropriate hole instructions in the rubber diaphragm.
N.B.! Cables for external communication outside the air
handling unit must be arranged at a minimum distance of
100 mm from any current-carrying (live) cable.

3.12 To Adjust the Supply Air Discs
The positions of the supply air discs can be adjusted after
dismantling the front grille of the lower section of the
unit. Use a 6 mm Allen key. The screws are located within
the outer holes in the corners.
When the front grille has been removed, the air discharge
direction of the front discs can be adjusted from the
backside of the front grille. Turn the discs by hand to the
appropriate setting.
The side discs can now also be adjusted without any further dismantling. The discs are accessible by putting your
hand inside the air handling unit.
Air handling unit viewed from above.
The front discs and side discs are
shown from this view below.
The factory-preset supply air distribution pattern and two
examples of possible modifi ed distribution patterns are
shown below.
Since each disc is individually adjustable, the possibilities
for modifying the air distribution pattern are practically
endless.
The arrows shown above
indicate the position of
each disc.

8.3 Switch clock
Basic functions for the switch clock can be preset
at INSTALLATION LEVEL under FUNCTIONS/OPERATION and the values can be read and set at USER
LEVEL.
TIME/DATE
The current date and time can be set and adjusted whenever
required.
The switch clock automatically takes leap years into consideration.
Automatic changeover between summer time/winter time to EU
Standard has been preset.
This changeover function can be blocked at INSTALLATION LEVEL
under FUNCTIONS/OPERATION
.
TIME CHANNEL
Times and days can be set when the unit is to run at high speed,
low speed or be stopped.
Eight different time channels can be set. If the same in-operation
times are to apply every day of the week (Mon-Sun), you need
only program one time channel. Different operation times for
each day of the week can be programmed by programming a
time channel for each day (Mon-Fri, Sat-Sun or Mon, Tues, Wed,
etc)
The time can be set as 00:00-00:00 if the deviating in-operation
period is desirable for the entire 24 hours period.
YEAR CHANNEL
The year channels make it possible to set deviating in-service
times for parts of the day during certain parts of the year. Eight
different year channels (yearly time schedules) can be set. The
year channels over-modulate the time channel during the hours
of the day and the days that the year channel is active. The year
channel dates indicate the dates between which the year channel shall apply and the year channel hours indicate the hours of
the day between which the year channel will steer the controller
to operate the rotary heat exchanger at a specifi ed speed. Other
times within the year channel still apply to that time channel.
The time can be set as 00:00-00:00 if the deviating in-operation
period is desirable for the entire 24 hours period.
Functions for summer night cooling, prolonged operation, etc.,
operate also when the year channel is active.
8.4 Filters
(and anti-frosting function of rotary heat exchanger)
There are two types of fi lter monitoring:
Calculated fi lter monitoring (preset at factory) monitors the fan’s
speed increase conditional on the degree of fouling in the fi lter.
The calibration involves taking airfl ow 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 fi lter. The alarm limit is preset in Pa.
8.4.1 Readings
When reading the fi lter status, the fi rst value shows current value
and the second value shows current alarm limit.
8.4.2 To Calibrate the Filters
The fi lters must be calibrated for the fi rst time during commissioning, when the duct system has been installed and adjusted.
After that every time fi lters are replaced.
Calibration should be activated for both the supply air and the
extract air if both fi lters are changed or for only for one airfl ow
direction if only one fi lter has been changed.
When fi lter calibration has been activated, the unit runs at high
speed for about 3 minutes.
After the fi lter has been calibrated, a speed increase of 10%, or
a pressure rise (= fouling of the fi lters) of 100 Pa is permissible,
after which an alarm is initiated indicating a fouled fi lter.
The alarm limit can be changed at INSTALLATION LEVEL under
ALARM SETTINGS.
8.4.3 Calibration - Rotary Heat Exchanger
If the anti-frosting function accessory for heat exchanger is installed (see 10.6.1.1) calibration can be selected from this menu.
When calibration R-HX is activated the fans are accelerated to
high speed for about 3 minutes.

10 FUNCTIONS
10.1 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 fi rst stop the air handling
unit before doing so.
10.2 Temperature Regulation (Control)
Select ERS Regulation. Then select ERS Regulation 1 or 2.
Control sequence for ERS regulation:
1. The temperature effi ciency 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 fl ow rate.
A neutral zone can be preset, which allows a lower supply
air temperature setpoint before regulation to a lower fl ow
rate begins. See 10.3.3.
When the supply airfl ow is regulated to a lower rate, the
heat exchanger will have ”excess heat”, i.e. warm extract
air, giving it capacity to maintain the supply air temperature required.
As the supply airfl ow is regulated to a lower rate, the air
pressure in the premises will become negative and this
will instead cause outdoor air to be sucked in through
leakage spots such as doors and windows. This outdoor
air will then be heated by the usual heating system of the
premises.
Downspeed regulation to lower the airfl ow rate occurs
from the current preset fl ow (high speed or low speed),
down to half of this fl ow rate. The degree of regulation
to a lower rate is also limited by the min fl ow setting of
the unit. When preset fl ow for low speed is near the min
fl ow rate, the effect of this regulation to a lower rate will
be small.

10.2.1.1 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 for
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 TEMPERATURE/SETTINGS.
Settings:
Value Setting Factory
range setting
Step 1 – 3 1
Breakpoint 15-23 °C 20 °C
(refers to extract air temp.)
EA/SA-Differential 1-5 °C 2 °C
The setting range for the Break Point and EA/SA difference is limited by Min. and Max. settings at INSTALLATION
LEVEL under CONTROL DISPLAY.
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.
See the chart to the right.
The following settings are possible at USER LEVEL under
TEMPERATURE/SETTINGS:
Value Setting Factory
range setting
Extract air temperature
X1 10-38 °C 15 °C
X2 11-39 °C 20 °C
X3 12-40 °C 22 °C
Supply air temperature setpoint
Y1 10-40 °C 20 °C
Y2 10-40 °C 18 °C
Y3 10-40 °C 14 °C
Factory setting means:
If the extract air temperature is below 20 °C (breakpoint),
the supply air temperature setpoint will be automatically
regulated to be 2 °C (EA/SA differential) lower.
If the extract air temperature is above 20 °C, the supply
air temperature setpoint will follow the curve according to
Step 1.
Breakpoints according to factory setting means:
If the extract air temperature is below 15 °C (X1) the setpoint for supply air temperature is constant 20 °C (Y1).
If the extract air temperature is 20 °C (X2) the supply air
temperature set point will be 18 °C (Y2).
If the extract air temperature is above 22 °C (X3), the supply air temperature setpoint will be constantly 14 °C (Y3).

10.2.3 Summer Night Cooling
The lower temperature at night is utilized to cool down
the building structure. This reduces the cooling load during the fi rst hours of the day. If a cooling unit is installed,
its in-operation hours will be minimized, thus offering savings. If no cooling unit is installed, a certain cooling effect
will still be realized.
When summer night cooling function is activated, the unit
fans operate at high speed, with a supply air setpoint of
10°C, from the preset time until the conditions necessary
for stop are satisfi ed.
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
control display.
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.
The function starts once per set time period.

If the extract airfl ow is set to 0 and the output to the
damper is inactive, the following will take place:
When conditions for start are met, outdoor air and exhaust air shut-off dampers remain closed. The damper in
the air recirculation section is opened. The extract air fan
is idle.
The supply air fan operates according to the preset supply
airfl ow and the heating coil downstream of the air handling unit operates according to the supply air temperature setpoint, until the conditions for stop are met.
10.2.4 Intermittent Night-time Heating
(applies to COMPACT Heat only)
The unit is utilized to heat the premises when it is normally
stopped by the switch clock.
The function requires connection of an external room
sensor. Connect the TBLZ-1-24-2 Room sensor by means
of the modular cable supplied, to an optional connection
marked Internal BUS 1.
When the function is activated, the air handling unit detects when the room temperature drops below the preset
start temperature. The unit starts with preset fl ows and
the supply air temperature setpoint.
If extract air fan operation is not desirable, the extract
airfl ow can be set to 0.
The damper output can be set to be Inactive. This means
that the connected dampers (such as shut-off dampers
for outdoor air and extract air) will not be affected. These
dampers are normally closed when the air handling unit is
stopped and they also remain closed. The damper in the
air recirculation section opens at the same time.
Intermittent night-time heating does not affect a possible
extra temperature zone (Xzone) that regulates according
to its ordinary set point, if intermittent night-time heating
is in operation.
Conditions to be met for intermittent night-time heating
to start:
• The unit should operate in a time channel/switch clock
stop.
• The room temperature should be below set start tem-
perature.
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.)

10.2.5 Morning BOOST
(applies to COMPACT Heat only)
The unit is utilised to heat the premises during a preset
period prior to the switch-in time set on the switch clock.
The unit starts early and uses the separate settings for
operation and temperature regulation.
The preset time is the time difference between the start of
Morning BOOST to the start of ordinary operation.
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. The damper in the air recirculation section opens
at the same time.

10.2.7 External Temperature Sensors
An external room sensor and external outdoor sensor can
be connected to the IQnomic control unit. 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 0 when the room sensor is used and in Position A
when an outdoor sensor is used.
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 unit from a supervisory system,
for instance.

10.3 Flow/Pressure
Basic functions are set at INSTALLATION LEVEL and
the values are read and set at USER LEVEL.
10.3.1 Fan Regulation
The type of regulation used for the supply air fan and the
extract air fan respectively can be selected individually.
10.3.1.1 Flow Regulation
Flow regulation involves operating the air handling unit
to keep the preset airfl ow constant. The speed of the fans
is automatically regulated to provide correct airfl ow even
if the fi lters begin to become clogged, air devices are
blocked, etc.
Constant airfl ow is advantageous, since the airfl ow always
is exactly as it was from the beginning.
It should however be noted that everything that increases
the pressure drop in the ventilation system, such as the
blocking of air devices and dust accumulating in the fi lters, causes the fans to run at a higher speed. This causes
higher power consumption and may also cause discomfort
in the form of noise.
10.3.1.2 Demand Regulation (Control)
The fl ow 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(+).
Required setpoint (separate for low speed and high speed)
is set as a percentage of the input signal.
The function can be limited so that the fl ow will not be
higher or lower than the preset max. and min. permissible
values respectively.
10.3.1.3 Slave Control
The fl ow is constantly regulated to be the same from the
one fan as from the other fan. If one fan is pressure-controlled or demand-controlled, the other one can be controlled as a slave to generate the same airfl ow.
The performance of the fan controlled as a slave can be
restricted if its maximum fl ow is set to a lower airfl ow rate.
Both fans cannot be controlled as slaves. If both are selected by mistake, the extract air fan will be forced to operate
in the fl ow regulation mode.

10.3.1.4 Clean Air Control
The Clean Air Control function is used in ventilation systems where the aim is to control the airfl ow according to
the content of emissions/impurities in the room air.
A VOC sensor (Volatile Organic Compounds) is installed
inside the air handling unit as standard. This sensor measures the content of emissions/impurities in % VOC.
When CO2 is emitted from an occupant, this creates a
proportional amount of, for the VOC sensor, measurable
emissions/impurities. For an approximate translation of %
VOC to CO2-content, see the diagram.
When the air handling unit is energised for the fi rst time,
the VOC sensor is initialised and this involves transmitting
a steady signal of approx. 50% VOC for 6 hours (applies
to the VOC sensors with Part No. 328964-01. VOC sensors with Part No. 328964-02 are initiated at the factory).
If the unit at a later time is de-energised, and is subsequently reenergised, the sensor is reinitialised for 15 minutes (provided that initialisation during the fi rst energising
occasion was not interrupted).
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 fl ows are then
equivalent to the preset min. fl ows. When the VOC sensor
instead measures contents of emissions/impurities that are
higher than the preset value, the supply air and extract air
fl ows are variably increased until the preset value or max.
fl ow is reached.
When the Clean Air Control function is activated, the fan
regulation modes are automatically selected (extract air
fan demand controlled, supply air fan slave controlled).
Later on, they can only be read under Functions in the
menu.

10.4 To Activate the Filter
Monitoring Function
The fi lter monitoring can take place in two ways, by rating
or with a pressure sensor.
Rated fi lter monitoring is activated on delivery.
If fi lter monitoring with pressure sensor is required, it must
be activated for the fi lters that are to be monitored.
Rated (factory-preset)
The fi lters are calibrated at 60% and 90% of the motor
signal. The airfl ow and fan speed are read and are stored
for rating the fi lters’ calibration value. If the unit operates
above the 60% motor signal, the current airfl ow and the
fan speed are continuously compared to the calibration
values. If the current values are greater than the calibration value + preset alarm limit, an alarm is initiated.
With pressure sensor (optional under Service Level)
The pressure drop across the fi lter is continuously monitored and an alarm will be initiated if the current pressure
is greater than the calibration value + preset alarm limit.

10.6 Heating
10.6.1 Heat exchanger
10.6.1.1 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, is wired to the control unit inputs for external BUS communication (Internal
BUS-1). Two nipples must be fi tted to the sheet metal wall
inside the unit’s extract air duct. See the illustration. Run
hoses through the insulation and connect them to the
pressure sensor’sminus and plus nipples.
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 Section 8.4.3.
When the function is activated the pressure drop across
the heat exchanger is continuously measured and the
reading is compared with the calibration reading.
If the pressure drop exceeds the preset limit value, a defrosting sequence is carried out. This involves, decreasing
the rotor speed to approx. 0.5 rpm to allow warm extract
air to melt possible frost.
The defrosting sequence will be cancelled when the pressure drop has fallen to half the limit value. The defrosting
operates for a max permissible period of 30 minutes.
If the pressure drop has not decreased within that max
permissible period after six tries during a 24-hour period,
an alarm will be initiated.
Note that the heat exchanger performs less effi ciently
while defrosting is in progress and that the supply air temperature will decrease downstream of the heat exchanger.

10.6.1.2 Heating BOOST
(applies to COMPACT Heat only)
Heating boost means that the air handling unit, operating in the normal fl ow regulation mode, increases both
the supply airfl ow and the extract airfl ow in order to carry
more heat into the premises.
The fans are allowed to work in the range between current fl ows (low speed, high speed) and preset max speed
fl ow.
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 fl ow is controlled by the function that transmits the
highest output signal to the fans.
The fl ow 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 fl ow (For particulars of how to set the max fl ow, see Section 8.2.2).

10.7 Cooling(Applies to an air cooler in-
stalled in the outdoor air duct only)
Cooling function 0-10 V and 10-0 V require an IQnomic Plus
module (function selector switch set to position 6). The module
is automatically activated. Wire the cooling connections to the
IQnomic Plus module. See separate instruction TBIQ.
Other functions can be connected to the control unit or the
IQnomic Plus module. If the function is connected to the
IQnomic Plus module, activation will take place automatically.
10.7.1 Operation
Activate the cooling function.
10.7.2 Temperature 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.
Both the cooling relays of the unit operate in parallel with the
signal and are energized when the cooling signal exceeds 0.5 V DC
and are de-energized when the signal drops below 0.2 V DC.
Connect the output for Cooling relay 1 and Cooling relay 2 to
terminals 1-2 and 3-4 on the control unit.
Stepless 10-0 V DC
Same as above, but the control signal is inverted where a 10 V
output signal means a 0 % cooling load.
On/off, 1 Step
Used if cooling in one step is connected. The air handling unit’s
cooling controller regulates the cooling load at 0-100 %. Cooling
relays 1 and 2 are energized when the cooling load exceeds 5 %
and are de-energized when the cooling load is less than 2 %.
The output contact for 0-10 V DC control signals operates in parallel with the 0-100 % cooling demand and can be used for indicating the cooling demand, for instance.
On/off, 2 steps
Used when cooling in 2 steps is connected. The air handling unit’s
cooling controller regulates the cooling load at 0-100 %. Cooling relay 1 is energized when the cooling load exceeds 5 % and is
de-energized when the cooling load is less than 2 %. Cooling relay
2 is energized when the cooling load exceeds 55 % and is de-energized when the cooling load is less than 50 %.
The 0-10 V DC control signal output operates in parallel with the
0-100 % cooling demand and can be used for indicating the cooling demand, for instance.
On/off, 3 Steps - Binary
Used when cooling with two inputs controlled with three binary
steps is connected. The cooling controller of the unit regulates the
cooling demand at 0-100 %.
On an increasing cooling load:
Cooling relay 1 is energized when the cooling load is above
5 % and is de-energised when the cooling load is between
40-70 %. Cooling relay 2 is energized when the cooling load is
above 40 %. Cooling relay 1 is energized again (together with
cooling relay 2) when the cooling load is above 70%.
On a decreasing cooling load:
Cooling relay 1 drops when cooling load is below 60 %, it is
energized again when cooling load is below 30 % and drops again
when cooling load is below 2 %. Cooling relay 2 drops when
coolng load is below 30 %.
The output for 0-10 V DC control signals operates in parallel with
the 0-100 % cooling load and can be used for indicating the cooling demand, for instance.

10.7.3 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.
10.7.4 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 to 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.
10.7.5 Outdoor Temperature Limit
Provision is available for setting an outdoor temperature-related blocking function in 3 steps. If the outdoor
temperature is below each step limit, the function of the
cooling relays will be blocked.
This function also restricts the 0-10 V output signal to
transmission in steps.
Step 1 maximises the output signal to 2.5 V, step 2 to 5.0
V and step 3 to 7.5 V.
10.7.6 Restart Time
The time should be set in such a way that it follows the
recommendations of the cooling machine supplier for the
number of starts per hour.
The restart time is calculated from the time when a relay is
energized to when it is allowed to be energized again.
The 0-10 V signal is delayed during the same period.
10.7.7 Cooling Min Air Flow
In order for the cooling function to operate the supply air
and extract air airfl ows must be greater than their respective limit values (preset at USER LEVEL under FLOW/PRESSURE).
The cooling min fl ow function can be blocked by setting
both fl ow limits to 0.
10.7.8 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.
10.7.9 Cooling BOOST
Cooling BOOST means that the supply air and extract air
airfl ows are increased to convey more cooling energy to
the premises.
Cooling BOOST cannot be combined with pressure regulation.
The fl ow increase takes place between current fl ow and
preset max fl ow.
The function can be selected in three variants as follows:
Comfort
The cooling outputs are activated if there is a cooling load.
When the cooling function is active and the temperature
in the supply air drops toward the preset SA min temperature, the fl ow will steplessly increase.
The GOLD runs at preset max fl ow when the supply air
temperature is same as the min. temperature.
Economy
Cooling BOOST Economy fi rst uses a higher airfl ow to cool
the premises, before a start signal is transmitted to the
cooling machines.
The function can also operate without the cooling function being activated.
On a cooling load, the fl ows are slowly increased up to
preset maximum fl ow. When the fl ows are up to max and
if a cooling load is still present, the output contacts for
cooling are activated.
The cooling boost function requires an outdoor air temperature of at least 2 °C lower than the extract air temperature for it to be activated. Normal cooling operation is
activated if the temperature difference is too small.
Sequence
The cooling BOOST Sequence is used if a cooling machine
is sized for a higher than normal cooling fl ow.
If there is a cooling load, the fl ow is increased up to the
preset max fl ow before the cooling function is activated.
The cooling function is delayed 1 minute after the airfl ow
is increased.
The cooling boost sequence is blocked if no cooling function has been selected.
Comfort + Economy
Cooling BOOST Comfort + Economy is a combination of
the two variants for increasing the airfl ow.
If the conditions for Cooling BOOST Economy are met, the
unit will begin increasing the airfl ow before the cooling
unit starts up.
If the conditions for outdoor air are not met, the fl ow 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 airfl ow.
If the conditions for Cooling BOOST Economy are met, the
unit will begin increasing the airfl ow before the cooling
unit starts up.
If the conditions for outdoor air are not met, the unit will
begin increasing the airfl ow when the cooling unit starts
up.

11 AUTOMATIC FUNCTIONS
11.1 General
The COMPACT has a number of automatic functions. The
operation of the unit is infl uenced when certain functions
are activated.
11.1.1 Starting Sequence
The COMPACT has a starting sequence with factory-preset
time delay between every step as follows:
1. The damper relay is energized and opens the shut-off
damper (if installed).
Time delay: 30 seconds.
2. The extract air fan starts and the heat exchanger is con-
trolled to provide max. heat recovery.
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 fi rst, and the heat exchanger as well, the
system also avoids chilling the premises with cool supply
air under cold weather conditions.
11.1.2 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.
11.1.3 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.
11.1.4 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.
11.1.5 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.
11.1.6 Density-corrected Airfl ow
The density of the air is different at different temperatures.
This means that a specifi c volume of air will change at different air densities.
The GOLD automatically corrects this, so that correct air
volume is always obtained.
The control equipment always shows the corrected airfl ow.
11.1.7 BOOSTER-function
(Applies to COMPACT Heat only)
COMPACT Heat can be used for heating the room with
BOOSTER function.
If the BOOSTER function is used, the extract air fan and
the heat exchanger are switched off. The damper in the air
recirculation section is reset and room air is circulated. The
louvre damper for exhaust air closes to prevent any cold
down draught.
The electric air heater (7.5 kW) heats up the air. A changeover damper in the lower section of the air handling unit
is reset and the air is led to the air discharge outlets at the
bottom of the unit. The air is discharged at high velocity
and follows the fl oor surface by means of the so-called
coanda effect. This enables long throw lengths and quickly
heats the entire premises.
The BOOSTER function is activated automatically when the
supply air temperature is higher than the extract air temperature or the room temperature.

13 MANUAL TEST
Note! Manual test running can cause indoor comfort problems. There is also risk of overloading the
system. The responsibility for discomfort and overload rests totally on the person who activates the
function.
Manual test run can take place for testing the inputs and
outputs, fans and heat exchanger, etc.
Used when the air handling unit is fi rst installed to make
sure that all the connections have been correctly wired.
Most alarms, functions and normal control modes will be
blocked while manual testing is in progress.
On a return to the other menu groups, the controller
resumes normal operation and all settings for manual testing will be terminated.

14 ALARM SETTINGS
14.1 Fire Alarms
EXTERNAL FIRE ALARM
Input Inp. 1 or Inp. Can be used for external fi re-control
equipment.
Manual or automatic resetting of alarms can be
selected.
INTERNAL FIRE ALARM
The air handling unit’s internal temperature sensors serve as fi re
protection thermostats. An alarm is initiated if the supply air temperature sensor registers more than 70 °C or when the extract air
temperature sensor registers more than 50 °C.
If an external Extract air/Room temperature sensor is connected and
activated, this works parallel with the extract air temperature sensor
of the unit.
FANS IN THE EVENT OF A FIRE
The fans in the air handling unit can be used for evacuating gases,
etc. The activated function works together with the External fi re/
smoke function or Internal fi re alarm.
If the air handling unit is idle, the pre-selected fans will start
up regardless of whether External Stop or Manual Stop has
been activated in the control display.
.
The damper relay in the air handling unit is energized and the
operating relay drops.
The dampers pre-selected for service in the event of a fi re, should
be wired to the damper relay and these dampers will open.
The dampers that are meant to close in the event of a fi re, should
be wired to the in-operation relay (control unit terminals 19-21) and
these dampers will close.

18 MAINTENANCE
Warning
Before carrying out any work, make sure that the
power supply to the unit has been isolated.
18.1 Filter Change
The fi lters should be changed when the fi lter alarm has
been activated.
Order new fi lters from Swegon or its representative!
Specify the type of air handling unit and whether the
change of fi lters involves one or two directions of airfl ow.
18.1.1 To remove the Filters
Pull out the handles to free the fi lters from the fi lter holder. Withdraw the fi lters.
It is advisable to clean inside the fi lter space while the
fi lters are gone.
18.1.2 To fi t new fi lters
Insert the fi lters into the fi lter holder.
Insert the fi lters as far as possible into the unit and press
lightly on the fi lter frames, so that they will fi t tightly.
Push in the handles (A) so that the fi lters are clamped in
place in the fi lter holder.
Carry out a fi lter calibration as described in Section 8.4.2.
18.2 Cleaning and Inspection
18.2.1 General
Clean the interior of the air handling unit as the need
arises.
Inspect the air handling unit thoroughly at the same time
that you replace the fi lters or at least twice a year.
18.2.2 Filter Space
Cleaning is most appropriate when you change the fi lters.
18.2.3 Heat exchangers
Check at least twice a year whether cleaning is necessary.
The cleaning work is carried out from the fi lter space.
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!
18.2.4 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.
18.3 Performance Checks
General performance checks should be carried out in conjunction with fi lter change or at least once a year.
It is then appropriate to compare the current performance
values of the unit with the Commissioning Record. Eventual deviations should be remedied.
18.4 Damper Actuator for the Change-over
Damper
Normally the damper actuator of the change-over damper
does not require cleaning or maintenance. If in spite of
this, access to the damper actuator is required, for example for checking that it operates correctly or replacement,
see the description below.
1. Remove the four screws that hold the front grille of the
lower section. Use a 6 mm Allen wrench. The screws are
located within the outer holes in the corners.
2. Remove the three screws that hold the profi led section in
front of the cover plate, see illustration.
3. Remove the seven screws that hold the cover plate and
dismantle it, see illustration.
4. The valve actuator is now accessible.
2. Reassemble in the reverse order.

19 ALARMS AND FAULT TRACING
19.1 General
Alarms are indicated by an alarm text and fl ashing LED
in the control display. Alarms for fi re are shown in all the
menu images. Other alarms are only shown if you are in
the Main Menu.
Quick reading or 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 functional component 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 be immediately 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 14, Alarm settings).
19.1.1 A and B Alarms
If selected, a type A alarm is indicated to the output for
Alarm Relay A (inputs Inp. 1 and Inp. 2 ), see also Section
10.8.
If selected, a type B alarm is indicated to the output for
Alarm Relay B (inputs Inp. 1 and Inp. 2 ), see also Section
10.8.
Alarms can be forwarded with different priority via these
terminals.
19.1.2 To reset the alarm
Alarms that require manual resetting can be reset from
the control display. Select RESET in the appropriate alarm
menu.
Alarms that reset themselves automatically will do so as
soon as the fault has been remedied.
Alarms can also be reset via a communication network.
19.1.3 To Change the Alarm Settings
See Section: 14 Alarm Settings.
