Heat pump controller

The control of the actuators (e.g. refrigerant shutoff valves and electrically regulated expansion valves) and the evaluation of the sensor system in the heat pump circuit (e.g. temperature sensors, heat pump circuit and refrigerant pressure temperature sensors) is carried out by the heat pump controller in the analogue way. The heat pump controller transforms the analogue signals into digital signals and also vice versa. The LIN bus is used as a data line for the communication between the heat pump controller and the control unit of the heating and air conditioning system (IHKR and IHKA).
