Solar function with thermostat function
This function always requires a 2nd cylinder as a pre-
heating cylinder, which is preheated by solar energy or
a wood heating system, for example. The temperature
of the preheating cylinder is determined via sensor
/
(TS3).
When the temperature for the preheating cylinder set
at the thermostat is reached, the transfer pump is acti-
vated to transfer heat to the main cylinder.
Relay kick
To prevent the pumps and valves from seizing up, they
are started for about 10 s every 24 h.
