Set the frost-protection temperature.
Factory setting: 5 °C
Activates the frost-protection facility when the temperature falls be-
low the set temperature.
Setting range: 5 °C to 10 °C.
Activate the "optimised time programme" function.
Factory setting: 0
If the "optimised time programme" function is activated, the set-

Factory setting: 5 minutes
The actuation time can be optimised depending on the running
time of the thermal actuator.
Setting range: 0 to 10 minutes.
Change the service code for the service menu.
Factory setting: 1234
