1. INTRODUCTION
The air handling unit is designed to ensure good ventilation of premises. Air handling unit removes indoor air containing
carbon dioxide, various allergens or dust, while replacing it with ltered fresh air from outside. As the outside air is usually
colder or warmer than the air within the premises, an integrated recuperator collects thermal energy from the indoor air and
transfers the majority of it to the supply air.
When a recuperator is not capable of reaching a desired temperature, heaters or coolers may be additionally activated.1
Heat exchangers and heaters (or coolers) are designed to compensate for heat/cool losses during
ventilation, therefore, we do not recommend using the unit as the main heating/cooling source. The
unit may not reach a user-dened supply air temperature when the actual room temperature dif-
fers signicantly from the desired room temperature. This will lead to inecient operation of a heat
exchanger.
Make sure that the unit is installed in a designated location, all ducts and wires are connected before
turning it on. Check for foreign objects, debris or tools inside the unit. Make sure that air lters are
installed and condensate drainage is connected (if necessary). If in doubt, contact your installer or
“Komfovent” representative to make sure that the unit is operational.
We recommend that you always keep your device turned on; when no ventilation is required, you
shall operate the unit in a minimum mode (20%). This will ensure good indoor climatic conditions
and will reduce humidity condensation inside the unit, that may damage electronic components.

2. AIR HANDLING UNIT FUNCTIONS
To create a comfortable home environment, you can adjust ventilation intensity and air temperature as well as to create a
weekly ventilation schedule. Various additional functions facilitate control of all ventilation processes and reduce electricity
consumption.
2.1. Temperature control
Temperature in the air handling unit is maintained by measuring the actual temperature and comparing it to the user-
dened temperature. Then, depending on whether the supply air requires heating or cooling, heat exchanger or additional
heaters/coolers are activated. Available temperature control methods:
• Supply air temperature control – the unit supplies air of user-dened temperature.
• Extract air temperature control – the unit automatically selects the supply air temperature to ensure that the extract
air temperature is reached and maintained as quickly as possible. Room air temperature is measured by an integrated
extract air temperature sensor.
• Room temperature control – the unit automatically selects the temperature of supply air to ensure that the room tem-
perature is reached and maintained as measured by the sensor integrated in a remote controller. Control panel must be
installed in a room where temperature maintenance is required.
• Balance – Supplied air temperature will be maintained to be the same as extracted air temperature, therefore, selecting a
desired temperature is not possible. Extract air temperature is measured by an integrated extract air temperature sensor.
To maximize heating/cooling energy savings, priority is always given to the heat exchanger, so due
to its high eciency, there may be cases where slightly warmer (heating mode) or colder (cooling
mode) than user set temperature air will be supplied.
Selection of temperature control is described in chapter “Control and Settings”.
1 Depends on the equipment supplied.

2.2. Standard operating modes
4 standard operating modes are available on your air handling unit. Each operating mode has preset air volume and
desired temperature values:
AWAY NORMAL INTENSIVE BOOST
Ventilation
intensity 20% 50% 70% 100%
Set
temperature 20°C 20°C 20°C 20°C
These settings may be changed (see “Control and Settings”).
2.3. Special operating modes
4 special operating modes are available on your air handling unit. During activation, KITCHEN, FIREPLACE and OVERRIDE
modes are set for operation from 1 min. to 300 min. In HOLIDAY mode, operation time is set from 1 to 90 days or for a specic
date. OVERRIDE mode may also be activated by short-cutting designated terminal on the main board, i.e. by connecting a
switch, cooker hood or a motion sensor (see “Installation Manual”). Each operating mode has preset air volume and desired
temperature values:
KITCHEN FIREPLACE OVERRIDE HOLIDAYS
Intensity

2.4. ECO mode
ECO – an energy saving mode intended for minimizing power consumption. Power consumption is reduced by turning
o heating/cooling devices, making maximum use of outdoor air or decreasing fan speed. During ECO mode:
• Electrical heater is blocked, all other external air heating/cooling devices are switched o.
• Rooms are cooled/heated with the outside air without a recuperator when the outside air temperature falls within the
set temperature range.
• When supply air temperature is below a set minimum value (in winter) or exceeds a maximum value (in summer), the unit
attempts to maintain the air temperature by decreasing ventilation intensity.
Setting the temperature range, switching o recuperation or heating/cooling devices may be done in the ECO mode set-
tings (see chapter “Control and Settings”).
2.5. AUTO mode
During AUTO mode, ventilation intensity is adjusted by a weekly schedule or air quality in the premises, i.e. ventilation is
activated only when necessary or desired.
2.5.1. Weekly operation schedule
If you want the unit to operate when you need it, you can create a weekly operation schedule. The unit has 3 default
weekly operation schedules tailored to dierent situations. Also, you can create your own schedule:
Working week Oce Stay at home
At night the unit operates in AWAY op-
eration mode, and in the morning or
evening it switches to NORMAL opera-
tion mode.
The unit is switched o during the
working day.
The unit operates only during the work-
ing days: in NORMAL operation mode
until noon and in INTENSIVE mode in
the afternoon.
The unit is switched o during nights
and weekends.
The unit operates all the time: in AWAY
operation mode during the night and
in NORMAL operation mode during the
day.
Programs, times and days of a schedule may be changed (see chapter “Control and Settings”).
2.5.2. Air quality control function
Air quality control function activates ventilation only when necessary, i.e. when the air quality is poor. If the indoor air
quality is good, the unit will ventilate at minimum speed or stop. Air quality in the premises may be controlled by impurity
or humidity sensors connected to B8 terminal (see “Installation Manual”).
As air impurity and humidity control methods slightly dier, the air quality control function is divided into:
• Impurity control
Impurity function is controlled via the following sensors:
CO2 – carbon dioxide concentration sensor [0...2000 ppm];
VOC – air quality sensor [0...100 %];

6UAB KOMFOVENT we reserve the right to make changes without prior notice
DOMEKT_C8_guide_21-07
EN
Air impurity function automatically selects ventilation intensity in the range of 20–70%, based on air quality readings. If
air pollution is within the user-dened limits, fans will operate at minimum speed; as level of pollution increases, the unit will
increase ventilation speed and supply more fresh air to the premises. It is also possible to stop the unit when air pollution is
low. For this purpose, change a minimum ventilation intensity limit to 0% (see “Control and Settings”). Then the unit will turn
on periodically (every 2 hours by default) to inspect the air quality, and will ventilate until pollution is reduced, if necessary.
Type of connected sensors and range of ventilation intensity may be modied (see “Control and Settings”).
• Humidity control
Humidity control function allows dehumidication of air in the premises. Possible ways of dehumidication:
1. If outdoor humidity is measured via an additional humidity sensor, air in the premises will be dehumidied when
humidity level outdoors is lower than indoors. Indoor humidity is monitored by a integrated in a control panel. In the
settings: set sensor type RH and select one of the connected sensors for measuring outdoor humidity (see “Control
and Settings”). In AUTO mode fans are running at minimum speed as long as the indoor humidity is lower than the
setpoint (see “Impurity Control”). When humidity outdoors is lower than indoors and dehumidication of the prem-
ises is necessary, the fan speed will be increased gradually and drier air will be supplied.
2. If no outdoor humidity sensor is used, “Humidity Control” function operates the same way as the “Impurity Control”
function but instead of an air quality sensor, optional humidity sensor connected to the controller or integrated in the
control panel is used.
3. If an external DX unit or a water cooler is used (activated in “Control Sequence Settings”), additional dehumidication
is possible by cooling supply air. In this case, the supply air temperature setpoint is ignored and colder but drier air is
supplied until the desired indoor humidity level is reached. If an outdoor humidity sensor is used and the outdoor air
is drier, the unit will attempt lowering the indoor humidity by supplying drier outdoor air before activating cooling
units. Dehumidication with cooling devices is possible both in AUTO and standard ventilation modes.
To use a DX unit or a water cooler for dehumidication of supply air, activate an option “Allow dehumidifying with cool-
ing” (see “Control Sequence Settings”). An option to enter a value for desired humidity will appear in the settings of standard
ventilation modes.

Temperature control – select a method for temperature control
(see Chapter 2.1).
Air quality control – here you can activate and set-up air quality
control which will be used in AUTO mode (see Chapter 2.5.2).
• Impurity control – turning on/o an impurity control function. At
least one CO2 or VOC sensor must be connected to the controller
board to activate this function (see Chapter 2.5.2.). If ventilation
by a weekly schedule is required, this function must be turned o.
• Humidity control – turning on/o a humidity control function.
Humidity control function requires a humidity sensor. If no humid-
ity sensor is connected to the controller board, sensor integrated
in a control panel will be used for this purpose (see Chapter 2.5.2.).
• Sensor 1 – specify the type of the sensor connected to a terminal
B8 (see “Installation Manual”). If this sensor is not available, select “None”.
• Outdoor humidity – this option appears when one of the sensors is of RH type (humidity sensor). If any of the connected
sensors are installed in the outdoor air ow, specify which one. If none of the installed humidity sensors measure the
outside humidity, select “None”.

• Minimum intensity – select ventilation intensity at which the unit will operate when air quality (impurity or humidity) is
good. If 0% is selected, the unit will stop when air impurity level is low.
• Maximum intensity – select ventilation intensity limit, under which the unit will operate when air quality (impurity or
humidity) exceeds a dened value.
• Check period – specify how often the unit shall turn on to check air quality, when minimum intensity is set to 0%.
Fire damper1– parameters for the re damper system tests
can be set. It is possible to select either automatic or manual re
damper test. For automatic test, it is needed to set testing interval,
as well as time of the day, when the tests will be performed. Dur-
ing re damper test, AHU will be stopped for several minutes, re
dampers opened and closed. External re damper controller will
check are al the dampers functioning normally and will give the
signal for AHU to restart or will indicate alarm message if some-
thing is wrong in the re damper system.
Control sequence – here you can activate additionally con-
nected duct-mounted heating or cooling devices (see “Installation
Manual”) that will operate only when a heat exchanger or electri-
cal heater alone cannot reach a desired temperature.
Numbers indicate the order of activation. All units have an inte-
grated electrical heater, therefore it is factory-assigned as Stage 1.
You can also assign an “external coil” (duct-mounted water heater/
cooler) or an “external DX unit” (direct evaporation heat exchang-
er) as a stage. If an external coil is selected, you also must specify
its type: “Hot water” (used for heating), “Cold water” (used for cool-
ing). If additional heating/cooling devices are not available, you do
not want to use them or an electrical heater, select “None”.
If you turn o an electric heater and do not activate a duct-mounted heater, the desired air
temperature may not be reached when the outside air is cold.
• Frost protection – this setting is only available in units with counter-ow plate heat exchangers. This function is intended
to protect CF heat exchanger against freezing at low outdoor air temperatures and has the following settings:
Standard – the air-handling unit is stopped when outside air temperature drops below -4°C for longer than 1 hour.
Special – heat exchanger is protected against freezing by changing the intensity of airows, i. e. by supplying less cold
outdoor air and extracting more warm indoor air, thus preventing frost formation. This function is sucient to ensure frost
protection for temperatures up to -10°C.
1 Available only if optional re damper controller is congured and connected. Refer to Fire damper controller manual for more information.

Special frost protection mode changes the balance of airows, which may lead to pressure die-
rences indoors, therefore, this mode is not recommended in airtight buildings (A+ or higher energy
eciency class) or in houses with a replace.
External pre-heater – pre-heater, installed inside an outdoor air duct, upstream the air-handling unit, is switched on as
soon as the heat exchanger freezing conditions occur. Eciency of a heater depends on the outside air temperature, indoor
humidity and actual ow of ventilated air. Integrated pre-heater operates only on demand to protect the heat exchanger
against freezing. Under very low indoor humidity conditions, it is unlikely that the heat exchanger would freeze even at very
low outdoor temperatures. To ensure proper operation of the pre-heater, a control panel or a separate humidity sensor must
be installed in the ventilated premises (see “Installation Manual”).
When using the pre-heater, other duct mounted heating or cooling devices cannot be connected.
• Indoor humidity – this setting is necessary for estimating power of a pre-heater.
Possible settings:
Auto – indoor humidity is set automatically using an integrated in the control panel humidity sensor and/or external
humidity sensor connected to B8 terminal of the controller (see “Installation Manual”).
10...90 % – setting a xed indoor humidity value is possible when a control panel is installed in inappropriate location (or
is not used) and no outside humidity sensors are connected.

Wrong value of indoor humidity may cause antifreeze protection to malfunction and a counter-ow
heat exchanger to freeze.
• Allow dehumidication with cooling –this setting must be enabled to use a DX unit or duct-mounted water cooler to
dehumidify the supply air. An option to enter a value for desired humidity will appear in the settings of standard ventila-
tion modes (see Chapter 2.5.2).
Connectivity – you can congure
your PC network settings for remote use
via web browser: IP address and subnet
mask. You may also change other net-
work parameters, if necessary: Gateway
and BACnet ID. DHCP option automati-
cally assigns a free IP address in the lo-
cal network (do not use this option if
you connect your computer directly to
the unit).
„Status“ line shows connection be-
tween AHU and internet:
• Disconnected – AHU is not connect-
ed to LAN or internet network.
• No internet access – AHU is connected to LAN network and communicates with router, but internet is not accessible.
• Connected – AHU has internet access.
