CONNECTION TO THE POWER SUPPLY NETWORK
In order to connect the hot water storage tank with the heat pump to the power supply network first install an electrical socket
suitable for the current load of 16 A.
Connecting the heat pump to the power supply network must take place in accordance with the standards for electric appliances.
To comply with the national installation regulations, an all poles disconnect switch must be installed between the heat pump and
the power supply network.

HEAT PUMP OPERATION
The heat pump can be operated using an LCD touch screen (Fig. 10). If you press anywhere on the screen, the screen lights up.
When the screen is lit up, the operation fields are active.
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 - 65 °C. From 65 °C - 75 °C the water is heated by electrical heaters
(models ZG and ZGNT).
