3.4.2 Setting the external controls
• Set the room thermostat (3, accessory) and/or the
thermostatic radiator valves (4, accessory) according
to the instructions supplied with the control(s).
Note!
Vaillant offer room thermostat/ time control
accessories which give accurate and economic
room temperature control as well as improved
comfort.
Ask your installer!
The boiler will now operate automatically to provide
central heating for the conditions selected on the
external controls and also provide domestic hot water
on demand).
Whilst the boiler is operating, the boiler display (7, fig.
3.2) indicates the temperature of the water within the
boiler circuit. After the boiler stops operating the pump
and fan will continue to operate for a short period to
fully disperse the heat from the boiler.
Note!
The boiler incorporates an anti-cycling
economiser control to prevent energy wasteful
ON and OFF operation of the boiler for short
periods when in the central heating mode. When
turning the room thermostat to a higher setting
there may therefore be a short delay before the
boiler operates.

control knob all the way to the very left switches OFF
heating),
