When the outdoor temperature is lower than a settable limit (winter), outdoor
compensated supply air temperature control will be active, otherwise (summer)
cascaded room temperature control as in room cascade type.
Outdoor dependent supply air or extract air
Outdoor temperature dependent switching between supply air temperature control
and extract air temperature control.
When the outdoor temperature is lower than a settable limit (winter), outdoor
compensated supply air temperature control will be active, otherwise (summer)
cascaded extract air temperature control as in extract air cascade type.
Outdoor compensated room cascade
The room temperature can be compensated when the outdoor temperature
increases. One can, for instance, imagine accepting a slightly higher room
temperature if it is warm outside or, conversely, a slightly lower temperature if it is
chilly. This function is included to conserve energy.
Outdoor compensated extract air cascade
The extract air temperature can be compensated when the outdoor temperature
increases. One can, for instance, imagine accepting a slightly higher extract air
temperature if it is warm outside or, conversely, a slightly lower extract air
temperature if it is chilly. This function is included to conserve energy.
Extract air depending supply air
A difference between extract air temperature and supply air temperature can be
configured to maintain the supply air temperature setpoint to follow extract air
temperature with this difference (+10°C to -10°C). Supply air temperature setpoint
= extract air temperature + difference.

Room temperature sensor
 None
 1
 2
 3
 4
Select the number of room sensors.
The average value of selected sensors is used in the control loop.
Outdoor sensor
 No
 Intake
 Outdoor
 Outdoor + Intake
Select the type of outdoor temperature sensor.
If only Intake is selected then it will have the same characteristics as the outdoor
temperature sensor.
Extract air temperature sensor
 No
 Yes
