If parameter Control variable (see Ch. 6.5.8) is set to Const supl. , this parameter
is not displayed.
With this parameter the control behaviour in setback operation is defined. This setting
applies for the operation in heating program 1… 3 as well as the presence and ab-
sence function. If the external sensor fails, an automatic change-over from Frost to
Setback is initiated.

the setback temperature setpoint depending on the gra-
dient set. The heating circulation pump continues to
operate. This is activated automatically if the external
sensor fails.
