Changing Room Temperature
In case a separate external room temperature controller
(thermostat) is installed, the desired room temperature
will be adjusted using this device.
Make adjustments using the appropriate operating
instructions only.
Note:
lf thermostatic radiator valves are installed in the
room where the control is installed they must be
fully
open.
In case the room temperature setting on the separate
room temperature controller is not sufficient to achieve
the desired room temperature (e.g. during a particularly
cold winter), the boiler water temperature can be adjusted
accordingly.
