LECTRICAL CONNECTION
All electrical connections must be performed by an authorised specialist in accordance with the local regulations
governing electrical installation work. The electrical cables must not come into contact with any hot components.
Usually cables for power supply, circulation pump, valve drive and flow temperature sensors are wired ex-works.
Just the outside temperature sensor as well as an optional temperature limiter and room thermostat has to be con-
nected on site (fig. 4).
Remove the cable jumper if an additional wired room thermostat is connected (fig. 4).
If the heating controller possesses RF thermostat interface please refer to the MuB both of the RF thermostat
and heating control.
Further information about electrical connections exists in the MuB of the heating control.
