The controller calculates the temperature difference between collector sensor
S1 and store sensor S2. If the difference 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.
Afterheating (R2) can be carried out with a thermostat function (S3). If the value
at S3 reaches the switch-on temperature for the afterheating, the relay is switched
on. If the value exceeds the switch-off temperature for the afterheating, the relay
is switched off again.
