Controller Description
The controller features two PT1000 probe inputs and one output for switching the heat pump. It is powered by a 12 Volt adapter and lacks buttons to prevent unauthorized setting changes. Technicians can adjust settings using two potentiometers:

T_OFF Potentiometer: Sets the delay time for pump switch-off to ensure water flows through the storage tank heat exchanger.
Diff_Temp Potentiometer: Sets the temperature difference between the solar collector and the water tank to activate the pump.

The display shows the adjusted values or the temperature in the solar collector. Faults are indicated by LED lights and sound alerts. The anti-freezing function activates the pump in cold conditions to prevent freezing. The Vacation mode maintains the tank temperature to prevent overheating when not in use.
