Wheretofindthecontrols
5592 550 GB

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.
Make adjustments using the appropri-
ate operating instructions.
Please also note:
It is not recommended that thermo-
static radiator valves are intalled in
the same room as the controller.
If thermostatic radiator valves are
installed in the room where the con-
troller is fitted they must be fully open.

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.
Your heating system and, if installed,
your room temperature controller
Vitotrol 100 or similar programmable

Start-up/shutdown
5592 550 GB

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 ON:
Set rotary selector "tr"tothe
required heating temperature.
Switching OFF:
Turn heating rotary selector "tr"to
"9".
DHW
When in operation with a separate DHW cylinder, DHW temperature is regu-
lated at the temperature control on the DHW cylinder. This DHW cylinder ther-
mostat is a required under part L of the building regulations

additional energy by your own actions.
The following measures will be helpful:
&Correct airing.
Open windows Abriefly whilst
closing all thermostatic valves B
&Never overheat;
endeavour to achieve a room tem-
perature of 20 °C; lowering the room
temperature by each degree saves
up to 6% off your heating bills.
&Close shutters (if installed) on win-
dows as dusk falls.
&Adjust thermostatic valves Bcor-
rectly.
&Never cover radiators Cand ther-
mostatic valves B.
&Make the best use of the adjust-
ments offered by the control unit D.
&Regulated DHW consumption: A
shower generally requires less
energy than a bath.
