SUMMER/WINTER CHANGEOVER LIMIT
Parameter
number
Description
The limit for summer / winter changeover is used to activate and deactivate the heating circuit throughout the
year, based on the outside temperature.
In “Automatic” mode, the heating function starts and stops automatically, meaning no manual intervention is
required by the user.
- The function is not active in Comfort mode (corresponding to the
symbol)
- When reaching an outside temperature of 25°C (730=25°C default setting) the heating function stops and
the "ECO” symbol is shown on the display.
Default setting
730 = 25°C

ACCELERATED HEATING
Parameter
number
Description
Accelerated heating is used to switch over more rapidly from the reduced set point to the Comfort set point,
reaching a new set point (Comfort set point + the value parameter of 770).
In this way, the heating operating time is reduced.
During accelerated heating, the room temperature set point is increased to the value set for parameter 770.
The higher this value, the lower the heating time; the lower the value, the longer the heating time.
Accelerated heating is only active when switching from the reduced set point to the Comfort set point.
To activate the function, set a value from 0 to 20°C.
Default setting
770 = - - -
