period of time, close quick-acting valve in the
gas supply line and turn off gas cylinder. Green
indicator lamp ‘Operation’ (under rotary control
knob).
When the appliance is switched on (heating
or ventilation) the green indicator lamp must
be illuminated (the fan is running). If the
indicator lamp is not illuminated, possibly
check the (main) switch. For this purpose
observe respective instructions of the vehicle
manufacturer.

is burning, the green indicator lamp lights
up with twice the intensity. This also makes
it possible to determine the instantaneous
switching point of the room temperature.

Opening the window switch and closing it again
is the equivalent to switching off/on at the
control panel (e.g. performing a fault reset)!
