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.
Please also 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 using the boiler
water temperature selector dial
