DESIGN AND OPERATING PRINCIPLE
Supply fan
Extract fan
*Bypass damper
Extract filter
Control unit
Temperature sensor for heat
exchanger freezing protection
Cable glands
Service side
Access door for inspection and maintenance
of the filters and heat exchanger
Cross-flow heat exchanger

Left-handed modification
The service panel is equipped with a detachable access door with manual bolts for cleaning or replacement of the filters and heat
exchanger. The control unit is positioned inside the unit casing.
The power and the ground cable are to connect to the control unit through the cable glands in the unit casing side.
The plate enthalpy cross-flow heat exchanger is made of polymerized cellulose.
*The bypass damper is open or closed depending on operation mode of the unit.
**At the request of the customer the unit can be equipped with a humidity sensor. The humidity sensor is purchased separately as an
accessory. 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 operation mode. Installation and connection of the humidity sensor is carried out on site by the service technician.
LEFT-HANDED AND RIGHT-HANDED MODIFICATIONS
Choosing the right arrangement can improve the ease of installation, shorten the length of the ducts and reduce the number of air
duct bends.
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 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 enthalpy heat exchanger allows to recover humidity as well as heat.
In the summer period, the supplied fresh air is cooled and dried by the heat exchanger, in the winter period it is heated and moisturized.
The water vapour is devaporated from the stale wet air and absorbed with heat exchanger plates.
The released heat and moisture are transferred to the supply air. The transferring of dirt, odours and microorganisms from one air flow
to another is excluded.
