2.3 Commissioning

The room unit will automatically be switched on as soon as power is present. If re-
quired, the heating engineer can change the parameter settings to meet individual
needs.
If, with weather compensation and room temperature influence (controller setting), the
room is equipped with a thermostatic radiator valve, the latter must be locked in its fully
open position, thus ensuring maximum flow through the radiator.
