HEAT PUMP OPERATION
The heat pump can be operated using an LCD touch screen (Fig. 9). When the heat
pump is connected to the water and power supply mains and the boiler is filled with
water, the heat pump is ready to be used. The heat pump heats the water in the
range 10 °C - 55 °C. From 55 °C - 75 °C the water is heated by electrical heaters.
