Where to find the controls Changing the room temperature In addition to the boiler control unit, a separate room temperature controller must be installed in one of the living rooms to comply with part L of the building regulations if the heating system is to be regulated in accordance with the required room temperature.
Start-up/shutdown Starting the heating system The initial start-up must be carried out by your heating contractor. Before you switch ON a heating system that has been switched OFF for longer periods, it would be advisable to contact your CORGI registered gas installer. Switch ON the mains power.
Settings Heating If the room temperature controller Vitotrol 100, or similar programmable room thermostat is connected, then the room temperature is controlled from there. Observe the separate operating instructions. Should the room temperature controller not produce sufficient heat (e.g. when it's very cold), the heating temperature can be changed at the rotary selector "tr".
Switching OFF Switching OFF Vitodens with frost protection Switch OFF the equipment if you don't want to use the boiler for a few days. Turn rotary selector "tr" to "9". Boiler frost protection is active. Shutting down the heating system Shut down your heating system completely, if it will not be needed for longer periods of time (several months).
