6 Electrical connection
When establishing the electrical connections, also observe the
documentation and wiring diagram of the accessory being connected
( chapter 2.12).
CAUTION:
Risk of electric shock.
Always isolate the wall mounted gas condensing boiler from the
power supply before working on the electrical parts.
NOTICE:
Short circuit.
Only use original cables if they must be replaced.
In order to commission and shut down the wall mounted gas condensing
boiler, the mains plug and therefore the socket (230 V AC, 50 Hz) must
be accessible at all times. The socket must be earthed (earthing
contact).
Use a 2-wire power cable with 0.4 - 0.8 mm

cross-section for all 24 V
AC connections on the terminal strip.
6.1 Control principle
The wall mounted gas condensing boiler is suitable for control according
to the principles of room temperature-dependent and weather-
dependent control.
• In the case of room temperature-dependent control, the user
interface in 1 room controls the temperature required within it (room
temperature-dependent controller). In order to control the
temperature correctly, radiators must be equipped with manual
radiator valves or the thermostatically controlled radiator valves
must be fully open ( figure 24).
• With weather-dependent control, the temperature in all rooms is
controlled by thermostatically controlled valves mounted on the
radiators. The controls can be installed in any location ( figure 25).
