7.13 Setting the summer/winter time changeover
In addition to the outside temperature, your control unit considers the ability
of
the building to store heat and its thermal insulation (creating from these
the
"Adjusted outside temperature", Æ Fig. 14). After a delay, it automatically
changes over between summer and winter mode.
Summer mode
Heating operation is switched off if the "Adjusted outdoor temperature"
exceeds
the factory-set changeover threshold of 17 °C.
Summer mode is indicated on the display with symbol .
DHW heating remains operational.
Press "Day mode" if you want to heat at short notice in summer mode.
The heating system returns to automatic summer mode if you press "AUT".
