 Frost protection mode
Parameter Effect
Outdoor air reg. At this setting, the appliance operates solely in frost protec-
tion mode. The preheating coil control only measures the
outside temperature.
Supply air reg. At this setting, the appliance operates in comfort mode. In
addition to the outside temperature, the supply air tempera-
ture is also measured.
Passive house
reg.
The preheating coil is controlled to ensure that the supply
air temperature does not fall below the 16.5°C specified in
the passive house criteria.
 Condensate prevention
 Enable condensate prevention
The Condensate prevention function is intended for units without
an enthalpy heat exchanger in areas with a subtropical climate.
If the unit is in ventilation mode, and this parameter has the value
"On", the unit checks the following conditions:
- Outdoor air temp.> Extract air temp.
- Extract air temp.+ Offset condensate prevention< Outdoor
air dew point
If both conditions are met, the unit switches the fans off. After
a shutdown, the unit switches on the fans cyclically and checks
whether the conditions are still valid or whether ventilation mode
can be resumed.
Interval between measurements min 60
Duration of measurement min 5
 Offset condensate prevention
This parameter changes the shutdown point for Condensate pre-
vention. This allows the fans to be switched off 2K before the dew
point temperature is reached, for example.
 Ventilation unit
 Device type
This parameter is set at the factory. The parameter can only be set
after the controller assembly has been replaced.
