The controller calculates the temperature difference bet-
ween collector sensor S1 and store sensor S2. If the diffe-
rence is larger than or identical to the adjusted switch-on
temperature difference, the pump (R1) will be switched on
and the store will be loaded until the switch-off temperature difference or the maximum store temperature is reached.
With another temperature differential function (S3/S4)
heating circuit backup (heating circuit return preheating) is
possible via a valve (R2). With a thermostat function (S3)
domestic hot water afterheating (R4) can be carried out.
