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.
Preheating of the washing machine inlet (R2) can be carried out with a thermostat
function. If the value at S4 reaches the switch-on temperature for the washing
machine function, the function will be switched on and the temperature will be
maintained at the desired value for the adjusted time by means of the valve. After
the adjusted time has elapsed, the relay will be deactivated for the same duration.
