Figure 3: Simplified heating diagram of configuration A. The yellow letters refer to explanatory notes of the function blocks, the blue
letters refer to explanatory notes of the temperature sensors. The outdoor unit of the heat pump is connected to the exchanger in the
storage tank by means of the refrigerant distribution in the direct condensation mode. The temperature of hot service water is
controlled automatically by a thermostatic mixing valve and it does not have to be controlled by the controller in any way. A
thermostatic valve for heat offtake for the radiators is not essential, nevertheless it enables a small continuous heat offtake from the
top part of the tank into the heating system. We always place the outside temperature sensor out of the flow of air cooled by the
outdoor unit.
