Fan mode
Choose between the following modes:
•
Auto: gives you an optimized function. The temperature is automatically controlled in
accordance with the unit's internal and optimized algorithms.
•
Min.flow: The system is forced to use a set minimum air flow.
•
Boost flow: The system is forced to boost the air flow. Useful for example if you get an
unpleasant smell indoors and need to air the building.
•
Max. flow: The system works at set maximum air flow.
•
Stove: This mode should be used when the stove/fireplace is used. The supply air fan works
at a higher speed than the exhaust air fan, to compensate for the air the stove extracts.
•
Kitchen: Use this mode when the cooker fan is running. The supply air fan works at a higher
speed than the exhaust air fan, to compensate for the air the cooker fan extracts.
Kitchen mode can also be started via an external switch, if it has been connected to one of the
external inputs on the terminal block.
•
ECO: Suitable to use when no one is at home. The fans switch to minimum flow, but
increase to normal flow when there is need for higher temperature. The setpoint temperature
is automatically lowered to the equivalent of ECO adjust.
•
Fire: To be used above all when testing the fire function. The supply air fan stops at the same
time as the exhaust air fan works at its maximum speed.
•
Off: All fans are switched off..
