DESIGN AND OPERATING LOGIC
Unit operation logic.
Warm stale extract air from the room fl ows through the air ducts
to the unit, is purifi ed in the extract fi lter, then it is moved to the
heat exchanger and exhausted outside by the extract fan. Clean
cold air from outside is moved by supply fans to the unit where it is
purifi ed through the supply fi lter. Then clean air fl ows through the
heat exchanger and is supplied to the room.
Heat energy contained in the warm extract air is transferred
to the fresh intake inside of the heat exchanger. Heat recovery
minimizes heat energy losses and operating heating costs.

• The unit casing is made of painted steel,
internally fi lled with a layer of heat- and
sound-insulating material.
• The unit casing incorporates a plate heat
exchanger, a supply and an extract fan.
• The front panel is installed on the
rotating sleeves to enable quick access
for the unit servicing.
• The casing bottom is equipped with
a protecting service panel to enable
service access to the automation unit.
• The G4 supply fi lter is installed between
the fan and the heat exchanger to
provide supply of fi ltered air to the
room. The G4 extract fi lter is installed in
the upper part of the front panel.
• The temperature sensor downstream
of the heat exchanger in the exhaust
air duct provides the heat exchanger
freezing protection. If the exhaust air
temperature drops down below +3 ºC
(+37.4 ºF) the heat exchanger freezing danger is registered. In this case the supply fan is turned off and the unit operates in the extract
mode only. After the heat exchanger is warmed up and the freezing danger is no longer imminent the unit reverts to the standard
operation mode.
