Note
The qualified contractor can set the parameters men-
tioned in the description of this parameter.
- Temperature to enable heat recovery bypass
- Temperature to block heat recovery bypass
- Hysteresis for heat recovery bypass
- Temp. differential for heat recovery bypass
 Outdoor air routing automatic: Bypass mode with
summer day detection
For bypass mode to be enabled, the following condition must be
met for 60minutes:
- Set room temperature+ Temp. differential for heat recovery
bypass< Outdoor air temp.
If all the following conditions are met, the appliance switches to
bypass mode.
- Extract air temp.- Hysteresis for heat recovery bypass> Out-
door air temp.
- Extract air temp.> Set room temperature
If one of the following conditions is met, the appliance terminates
bypass mode.
- Outdoor air temp.< Temperature to block heat recovery
bypass
- Extract air temp.- Hysteresis for heat recovery bypass< Out-
door air temp.
- Extract air temp.< Set room temperature
 Extract air routing autom.: Bypass mode subject to
extract air temperature
For bypass mode to be enabled, the following condition must be
met for 60minutes:
- Set room temperature+ Temp. differential for heat recovery
bypass< Extract air temp.
This delayed enabling prevents cooling down in spring and au-
tumn.
If all the following conditions are met, the appliance switches to
bypass mode.
- Extract air temp.- Hysteresis for heat recovery bypass> Out-
door air temp.
- Extract air temp.> Set room temperature
If one of the following conditions is met, the appliance terminates
bypass mode.
- Outdoor air temp.< Temperature to block heat recovery
bypass
- Extract air temp.- Hysteresis for heat recovery bypass< Out-
door air temp.
- Extract air temp.< Set room temperature
 Cooling/heating, heat recovery bypass
f Set the bypass mode control according to the temperature.
Parameter Effect
