Set room temperature

Set room temperature subject to operating condition
In the "Set value" menu, the set room temperature can be selected for
operating states of standard, reduced and holiday mode (see page 16).
Assumed return temperature
The current return temperature is determined (estimated) by the control unit.
This estimate is based on the current outside temperature and the cool down
characteristics of the building. To achieve this, a building type (construction
substance and thermal insulation) must be entered. Subject to the type of
construction, you may enter the building type as "Light", "Medium" or
"Heavy".
