DESIGNATION KEY
PURPOSE
The unit is designed to ensure continuous mechanical air exchange in houses, offices, hotels, cafes, conference halls, and other utility
and public spaces as well as to recover the heat energy contained in the air extracted from the premises to warm up the filtered stream
of intake air.
The unit is not intended for organizing ventilation in swimming pools, saunas, greenhouses, summer gardens, and other spaces with
high humidity.
Due to the ability to save heating energy by means of energy recovery, the unit is an important element of energy-efficient premises.
The unit is a component part and is not designed for stand-alone operation. It is rated for continuous operation.
Transported air must not contain any flammable or explosive mixtures, evaporation of chemicals, sticky substances, fibrous materials,
coarse dust, soot and oil particles or environments favourable for the formation of hazardous substances (toxic substances, dust,
pathogenic germs).

TECHNICAL DATA
The unit is designed for indoor application with the ambient temperature ranging from +1 °C up to +40 °C and relative humidity up to
60 % without condensation. In cold, damp rooms, there is a possibility of freezing or condensation inside and outside the casing.
In order to prevent condensation on the internal walls of the unit, it is necessary that the surface temperature of the casing is 2-3 °C above
the dew point temperature of the transported air.
The unit should be operated continuously, and in cases where ventilation is not necessary, reduce the air flow of the fans to a minimum
(20%). This will ensure a favorable indoor climate and reduce the amount of condensation inside the unit, which can damage electronic
components. Never use the unit for dehumidification, for example, of new buildings.
The unit is rated as a Class I electrical appliance.
Hazardous parts access and water ingress protection rating:
IP22 for the unit connected to the air ducts
IP44 for the unit motors
The unit design is constantly being improved, thus some models may be slightly different from those described in this manual.

DESIGN AND OPERATING LOGIC
The unit has the following operating logic: warm stale extract air from the room flows into the unit, where it is filtered by the extract filter,
then air flows through the heat exchanger and is exhausted outside by the extract fan. Cold fresh air from the outside flows into the unit,
where it is cleaned by the supply filter.
Then the air flows through the heat exchanger and is directed to the room with the supply fan. Heat energy of warm extract air is
transferred to clean intake fresh air from the outside and warms it up. The air flows are fully separated while flowing through the heat
exchanger. Heat recovery minimizes heat losses, which reduces the cost of space heating in the cold season.

The service side of the unit is equipped with detachable plates fixed by screws for filter cleaning and replacement operations. The control
unit is positioned inside the unit casing. The power cable and grounding cable are connected to the control unit via the electric lead-
ins placed at the side of the unit. The difference between the supply and extract air flow temperature leads to condensate generation.
Condensate is collected in the drain pan and is removed outside through the drain pipes.
Additional equipment for the unit is purchased separately as an accessory (is not included in the delivery set, available
separately):
• Humidity sensor (FS2 is connected to the terminal block, HR-S is connected to the controller).
The unit with an installed humidity sensor maintains a set indoor humidity point. As the extract air humidity rises above the set point,
the system automatically switches to the maximum speed. As the humidity drops down below the set point the unit returns to the
previous mode.
• CO2sensor (is connected to the controller).
The sensor is designed for indoor carbon dioxide concentration measurement and respective air capacity regulation through the
control output signal to the fan. Air capacity control based on CO2concentration is an efficient energy saving solution.
• VOC sensor (is connected to the controller).
Qualitative assessment of air saturation with contaminants (cigarette smoke, exhaled air, solvent and detergent vapours). The sensor
sensitivity can be adjusted with regards to the expected maximum level of air pollution. Enables on-demand ventilation which results
in considerable energy savings as air is exchanged only upon reaching the preset level of pollution.
• Duct preheater.
The heater maintains air temperature in the supply duct at level that prevents the heat exchanger from freezing. Heater installation
and connection to the unit are described in the heater user’s manual.
• Duct reheater.
The heater maintains the user-defined room air temperature. Heater installation and connection to the unit are described in the
heater user’s manual.

UNIT OPERATION MODES
Heat recovery
Warm extract air from the room flows into the unit and is cleaned in the extract filter. Then the air is moved through the heat exchanger
and is exhausted outside with the extract fan. Cold fresh air from outside flows into the unit, where it is cleaned in the supply filter.
Then the air flows through the heat exchanger and is directed to the room with the supply fan. Supply air is heated in the heat exchanger
by transferring the heat energy of warm and humid extract air to the cold fresh air. The air flows are fully separated while flowing through
the heat exchanger. Heat recovery minimizes heat losses, which reduces the cost of space heating in the cold season.
SUPPLY AIR EXHAUST AIR
INTAKE AIR
EXTRACT AIR
Summer Cooling mode (for the units with bypass only)
The bypass damper is opened, the extract air that is removed from the premises is routed along the bypass duct and does not come in
contact with the heat exchanger. The temperature of the air is not changed after passing through the heat exchanger.
SUPPLY AIR EXHAUST AIR
INTAKE AIR

Freeze protection (danger of freezing appears when the exhaust air temperature downstream of the heat exchanger is lower than
+5 °C and intake air temperature upstream of the heat exchanger is lower than -3 °C for the units with preheating, and when exhaust
temperature downstream of the heat exchanger is lower than +3 °C for the units without preheating): to protect the heat exchanger from
freezing in the cold season, the unit has a Frost Protection mode based on the temperature sensor readings. The temperature sensor is
installed in the exhaust air duct downstream of the heat exchanger. The Frost Protection mode is activated at an exhaust air temperature
of +3 ˚C. After temperature increase the unit returns to the previous operation mode.
In the KOMFORT (EC) D5(B)180-E S11 units the frost protection mode must be activated, see the User’s manual of the control panel.
In case of freezing danger, the supply fan is turned off in the KOMFORT (EC) D5(B)180-E S14 units. After temperature increase the unit
returns to the previous operation mode.
The KOMFORT (EC) D5(B)180-E S21 units have three frost protection modes:
- gradual reduction of the supply fan speed
- with the bypass
- with the electric preheater (if the unit is equipped with a duct preheater).
Mode selection and settings are described in the control system user’s manual.

UNIT MOUNTING
To attain the best performance of the unit and to minimise turbulence-induced air pressure losses connect the straight air duct section
to the spigots on both sides of the unit while mounting.
Minimum straight air duct length:
• equal to 1 air duct diameter on intake side
• equal to 3 air duct diameters on outlet side
If the air ducts are too short or not connected, protect the unit parts from ingress of foreign objects.
To prevent uncontrollable access to the fans, the spigots may be covered with a protecting grille or other protecting device with mesh
width not more than 12.5 mm.
While installing the unit ensure convenient access for subsequent maintenance and repair.
The unit must be mounted on a plane wall (ceiling).
Mounting of the unit to an uneven surface can lead to the unit casing distortion and operation disturbance.
Fix the mounting brackets on the wall or the ceiling depending on the type of installation.
Mounting
bracket
Fastener Expansion
anchor
Fasteners for mounting are not included in the delivery set and should be ordered separately.
The air ducts must be slipped over the unit flanges until tight. Flexible air ducts must be rigidly fixed with a metal worm clamp.
