specified switch-on temperature, and turns off when the temperature rises above the specified switch-off
temperature. Three periods per day can be defined.
Factory setting
Period 1: 04:00 to 05:00, switch-on temperature 40°C, switch-off temperature 45°C. Period 2: 10:00 to
10:00 (no auxiliary heat is switched on).
Period 3: 17:00 to 22:00, switch-on temperature 50°C, switch-off temperature 55°C.
Setting range, switch-on temperature: 10 to (switch-off temperature – 2°C).
Setting range, switch-off temperature (switch-on tempe 2°C) to 80°C.
You can disable one or more periods by defining the same time for switch-on and switch-off. By default,
the time for both switch-on and switch-off is 10:00 in period 2.
During times other than the set periods, the auxiliary heating device is not switched on, even if the tank
temperature reaches the specified switch-on temperature.
NOTE:
If there is no T3 sensor fitted in the upper part of the tank, the auxiliary heating is controlled by the
signal from the T2 sensor.
Auxiliary heating periods are specified per day. The time for switch-off must always be later than
the time for switch-on in order for the auxiliary heating device to be switched on. If you want the
auxiliary heating device to be switched on between, e.g., 17:00 and 06:00, you define the first
period from 17:00 to 23:59 and the second period from 00:00 to 06:00.
