NOTE
For ensuring safe and efficient operation of the additional heat source for DHW
(DHW, solar collectors) the controller for the external source has to be set to
maximum water temperature of 85 °C. The recommended temperature setting is
65 °C or lower.
The highest allowed water temperature in the heat exchanger is 110 °C.
5.8 Electrical connection
The hydraulic connection of the device to the water supply is followed by the electrical
connection. For connecting the device to the electricity the plug of the connecting cable has to
be plugged into a standard socket and the device will start up automatically. The
commissioning procedure is described in chapter 6.4.
CAUTION
The device has no additional switch for commissioning, it will turn on immediately
after connecting it to the electricity grid. Before turning on the device it is necessary

The connecting cable has a standard plug suitable for a standard socket (16 A;
230 V ac). This socket has to have its own power supply directly from the main
electrical cabinet. Other devices must not be connected to the same line.
DANGER
The device must be connected to the electricity supply where the RCD (FID) switch
of type A is installed.
If you want to connect an alternative heating source or an external input source to the device,
it is necessary to follow the instructions in chapter 5.8.1.
5.8.1 The electrical connection of the additional heat source and external switch
All the electrical connections are carried out on the right side of the device. The connection
clips are located under the plastic cover. The connecting cable is connected to the leftmost
connection clip.
