When commissioning the ComfoAir, the Preheater programme can usually be left at level 2:
(factory setting). In areas with frequent cold spells in winter (frequent periods of -10°C or lower), level 1
should be selected:
P54 Confi rming the presence of a bypass.
The standard ComfoAir confi guration includes a bypass. Therefore, leave the value at '1'.
P56 Setting the required air volume in the house.
• nL: "normal air volume".
• HL: "high air volume".
Setting the air volume is the starting point for programming the air specifi cations and setting the fans.
P57 Setting the ComfoAir type.
• Li = "Left-hand version".
• Re = "Right-hand version".
With delivery the ComfoAir is correctly pre-programmed at the factory.
After an general reset the pre-programming is lost and the setting must be reset.
The right setting is mentioned on the identifi cation plate on top of the ComfoAir.
P58 Enter controller priorities.
• 0; The highest air setting is leading INCLUDING the
signals from the analogue inputs
• 1; The highest air setting is leading EXCLUDING the
