OPERATION

Heating operation

Setting the maximum radiator
temperature control
Turn the main switch (1) to the „l"
position.
Set the maximum radiator
temperature control to the desired
setting using the control knob (2).
We recommend the following
settings:
- Left setting during spring and
autumn,
- Middle setting during mild
winter,
- Right setting during cold winter.
Setting the external controls
Set the room thermostat (3) and/or
the thermostatic radiator valves (4)
according to the instructions
supplied with the control(s).
HINT! 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 (TURBOmax Plus
will also provide domestic hot water
on demand).
Whilst the boiler is operating, the
boiler display (1, fig. B.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.
