Functional description
Important
The ventilation system must always be operating!
Besides the four hours where the unit can be stopped by the control panel, it is not ad-
visable to stop the unit. The risk by stopping the unit for a considerable period is that
moist air can condense in the ducting system and in the ventilation unit with the risk of
water damage in the building construction, damages on the unit and sanitary problems.
Hence it is not advisable to stop ventilation – also during longer holidays. If necessary,
turn the unit to Fan Step 2 or 1 in Manual Operation instead.
Function
The unit supplies fresh outside air into the house.
Polluted and moist air is sucked out of kitchen, living room, bathroom etc. and led
through the unit, where by means of the heat exchanger the unit uses this air to heat up
the new, fresh air, before the fresh air is supplied into the house.
Control panel
The control panel is used for setting functions of the unit.
The control panel is described on page 29.
Automatic
Demand Mode
When the unit operates in Automatic Demand Mode, the flow rate is regulated accord-
ing to the humidity level in the house. It is measured by a humidity sensor, which is
situated in the extract duct of the ventilation unit.
•
At air humidity higher than 45 % RH the unit constantly operates on Fan Step 3
•
At air humidity below 45 % RH the unit will adjust air flow rates, by slowly reducing.
If the air humidity is below 45 % RH in a considerable period of time the unit will
start operating at Fan Step 1
The set point for Automatic Demand Mode is adjustable with the remote control. Auto-
matic Demand Mode is always recommended as it ensures air change to match the
demand. Automatic Demand Mode also prevents the house from drying out, especially
during winter.
