Description
Demand-control
In AUTO mode the unit adjusts automatically between fan step 1 - 3, so
that the air change matches the actual demand in the house. The unit tries
to maintain a comfortable air quality, measured in relation to the relative
humidity and the CO
2
level (CO
2
control is accessory). In case of high hu-
midity in the air the ventilation demand is increased and the unit adjusts
to fan step 3. In case of low humidity the unit goes down to fan step 1.
The CO
2
control adjusts the unit to step 4 in case of a high CO
2
level.
Manual operation
In Manual mode the user must adjust the fan step manually each time the
air change requirement changes. Fan steps from 0 to 4 are available. Step
0 and 4 are only active for 4 hours, after that time the unit returns auto-
matically to step 3.
Week program
In Week program mode the unit supplies a variable air exchange which is
adapted to the selected family profile (P1, P2, P3 etc.) See the list at the
back of this manual.

AWAY
The AWAY mode can be activated in periods where the house is unoccu-
pied and when there are no activities requiring air change. In AWAY mode
the unit runs at minimum air change, i.e. 2/3 of the time at fan step 1 and
1/3 of the time at fan step 0. All other functions are working normally incl.
heating and cooling coils, if connected. To deactivate this function press
CENTER, otherwise it deactivates automatically after 28 days and it auto-
matically goes back to the previous operation mode.
Warning!
Remember to deactivate the AWAY mode as soon as the house is occupied
again. Otherwise the house may be damaged as well as comfort for the
people is compromised.
