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 recom-
mend 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!
Fig. B.9: Setting the external controller
The boiler will now operate automatically to provide central
heating for the conditions selected on the external con-
trols (turboMAX plus will also provide domestic hot
water on demand). Whilst the boiler is operating, the
boiler display (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.
The boiler incorporates an anti-cycling economi-
ser 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.
