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:
• IP20 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 PRINCIPLE

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 through the air duct into the unit, where it is cleaned by the supply filter.
Then the air flows through the heat exchanger and is moved to the room by the supply fan.
Supply air is heated in the heat exchanger due to transfer of the heat energy of warm and humid extract air to the cold fresh air.
The air streams remain separated in the heat exchanger.
Heat recovery minimizes heat losses, which reduces costs for space heating in the cold season.
If the outside temperature drops down below -3 °C, the heat exchanger may freeze.
A freezing danger appears if the exhaust air temperature downstream of the heat exchanger is below +5 °C and the intake air temperature
upstream of the heat exchanger is below -3 °C for units with air preheating and when the exhaust air temperature downstream of the
heat exchanger is below +3 °C for units without preheating.
After increase of the exhaust air temperature the unit reverts to the previous operation mode.
Frost protection of the heat exchanger
• By reducing the speed (stopping) of the supply fan.
• Via a bypass duct with a bypass damper.
• By automatically switching on the electric supply air preheater.
When using a bypass duct, part of the cold air, bypassing the heat exchanger, enters the room, while the degree of heat recovery
decreases.
When the speed of the supply fan decreases, the air exchange in the room is unbalanced, up to a lack of air exchange.
The use of an integrated preheater ensures a constant temperature and volume of the supply air at low ambient temperatures.
In this case, heat recovery is maintained, and the energy expended during the operation of the preheater reduces the load on the space
heating system.
Heaters
Depending on the model the unit includes a preheater and a reheater of supply air (CIVIC EC D(1)BE2) or only a preheater (CIVIC EC D(1)BE).
The preheater prevents freezing of the heat exchanger and is located in the intake air duct before the heat exchanger.
The reheater is located in the supply air duct after the heat exchanger.
Condensate drainage
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 pipe.
Additional equipment
Additional equipment for the unit is available on a separate order.
• HV-2 humidity sensor;
• CO sensor;
• VOC sensor.
