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.
