Vitodens 100-W, WB1B Operating & User’s Information

Start-up/Operation

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

using the boiler water temperature selector dial

“tr”.
