thermostat setting (1 – 5). The green LED (b) for
operation is lit and simultaneously indicates the
position of the selected room temperature. The
yellow LED (g – water’s heat-up phase) will be
lit only when the water temperature is below
5° C!
The unit automatically selects the required
power level according to the temperature
difference between the setting on the control
panel and the current room temperature.
After reaching the room temperature set on
the control panel, the burner will switch off.
The warm-air fan will continue to run at a low
speed as long as the blow-out temperature (on
the unit) is higher than 40° C.
If the boiler is filled, the water will
automatically be heated at the same time.
The water temperature is then dependent
on the heating output being given off, and
the duration of heating required to reach the
desired room temperature.
Heating with drained water system
Set the rotary switch to the operational setting
‘d’. Turn the rotary switch (a) to the desired
thermostat setting (1 – 5). The green LED (b)
for operation is lit and simultaneously indicates
the position of the selected room temperature.
The yellow LED (g) will be lit only when the
temperature of the unit is below 5° C!
The unit automatically selects the required
power level according to the temperature
difference between the setting on the control
panel and the current room temperature. After
reaching the room temperature set on the
control panel, the burner will switch off.
SWITCHInG oFF
Use the rotary switch to switch off heater
(position f). The green LED (b) goes off.
If the green LED (b) blinks after switching off,
then the unit’s after-running is active in order to
reduce the unit’s temperature. This will end after
a few minutes and the green LED (b) will go off.
Always drain water contents if there is a
risk of frost!
If the appliance is not to be used for a
prolonged period, close the quick-acting valve in
the gas supply line and turn off the gas cylinder.
Red LED ‘Failure’
The red LED (h) will be lit if there is a failure.
Please consult the Trouble-Shooting list for
possible causes.
Reset (failure reset) the unit by switching it off
and back on.
If the window switch is opened, the heating
unit will stop operating and the red LED (h) will
blink. Once the window switch is closed, the
heating unit will continue operation and the
green LED (b) will be lit continuously.
Filling the water heater
Check if the rotary switch for the drain valve
(FrostControl) is set to ‘Operation’, meaning
that it is parallel to the water connection
and engaged.
When the temperature at FrostControl is below
about 7° C, first switch on the heater to warm
the installation compartment and FrostControl.
After several minutes, when the temperature
at FrostControl is above 7° C, the drain valve
can be closed.
Close the drain valve by pushing the push
button until it engages. Switch on power for
water pump (main switch or pump switch).
Open hot water taps in kitchen and bathroom,
(set preselecting mixing taps or single-lever
fittings to ‘hot’). Leave the fittings open for
as long as it takes for the boiler to displace
the air and fill up, and the water to flow
without interruption.
If just the cold water system is being operated,
without using the water heater, the heater
tank also fills up with water. To avoid frost
damage, the boiler must be drained through
the drain valve, even if it was not operated.
As an alternative, two shutoff valves, resistant
to hot water, can be fitted in front of the cold
and hot water connection.
