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
The unit operation is as follows:
Warm extract air from the room flows into the unit and is cleaned in the extract filters. Then the air is moved through the heat exchanger
and is exhausted outside through the air ducts with the exhaust fan. Cold fresh air from outside flows into the unit, where it is cleaned
with the supply filters. Then the air flows through the heat exchanger and is moved 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.

The unit is a frame structure made of rigidly fixed steel panels.
The panels are made of painted steel sheets and a galvanized steel sheet with a layer of mineral wool between for heat- and sound-
insulation. The service door enables access for maintenance and service operations.
The unit design enables installation of a bypass duct with a bypass damper to route the intake air stream without contacting the heat
exchanger.
The unit has three automatic heat exchanger freeze protection modes, depending on the unit model.
Units without heater: the supply fan turns off in case of a freezing danger*.
Units with a reheater (with preheater disabled): the bypass system is activated in case of a freezing danger*.
Units with a preheater: the pre-heating is turned on in case of a freezing danger*.
* 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.
The supply and extract air temperature difference during heat recovery may lead to condensate formation in the units with a polystyrene
heat exchanger. The condensate collects in the drain pan and removes outside.
Additional equipment (is not included in the delivery set, can be ordered separately)
Humidity sensor. The unit with the 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.
CO2 sensor. Measures the level of concentration of carbon dioxide in the room and generates a signal that controls the performance
of the fan. Air capacity control based on CO2 concentration is an efficient energy saving solution.
VOC sensor. 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.
