Resetting the appliance
Fig. B.9: Reset
When a hot water tap or the central heating system
requires heat, the boiler automatically ignites and starts
to operate. If the automatic ignition is not successful
within 10 seconds, then the boiler does not go into
operation and switches to „Lock out“.This is indicated
visually by the red indicator light (1). A new attempt to
ignite the flame can then only be performed after
pressing the „Reset“ button.
• Press the „Reset“ button (2) and hold for approx. 1
second.
If the device still shuts off after a third attempt,
then please consult your installer or Vaillant
Service Solutions.
Turning the boiler OFF
Fig. B.10: Setting the summer operating mode
To turn OFF the central heating only (Summer mode)
• Turn the maximum radiator temperature control knob
used to control the heating supply temperature (1) all
the way to the left.
Hint!
You can switch off the heating operation in
summer, for example, but the boiler will continue
to provide domestic hot water whenever a hot
water tap is opened.
To turn OFF central heating and hot water for short
periods of time
Fig. B.11: Shutting down the unit completely
• Turn the main ON/OFF control (2) to the „0“ position.
If you want to turn the boiler OFF for a longer
period of time (e.g. holidays), and there is no
danger of frost, then you should also turn off
the gas supply, the cold water service valve and
the electrical supply. Please note the frost pro-
tection hints in this regard (next page).
