Heating WITHOUT hot water requirement
1. Select required type of operation at
power selector switch (gas, electrical or
mixed operation).
2. Move rotary knob (j) on the control panel
to desired thermostat setting (1 – 9) for
room temperature.
3. Move rotary switch on the control panel
to ‘m’. The green ‘On’ indicator lamp (k)
on the control panel illuminates when the
equipment is switched on. During
electrical operation the yellow indicator
lamp (h) at the power selector switch also
illuminates to indicate 230 V operation.
In this operating position the yellow
indicator lamp (q) only illuminates at
water temperatures of less than 10°C!
Depending on operating mode (gas,
electrical or mixed operation) and power
requirement (temperature difference
between selected and current room
temperature) the unit automatically
selects the necessary power setting of
up to 7800 W.
When the selected room temperature has
been reached, the heater switches off
(independent of the water temperature).
Note: The water is automatically heated as
well if the boiler has been filled. The water
temperature can reach up to 80°C
depending on the power and the duration of
the heating.
Switching off
Move rotary switch on the control panel to
‘p’ to switch off.
The fan can continue to run after switching
off in order to utilise the residual heat.
Note: In order to prevent unintentional
overloading of the power supply when
resuming operation, it is advisable to set the
unit to gas operation at the power selector
switch after switching 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.
Gas operation fault
If a fault occurs during gas operation the red
indicator lamp (r) on the control panel
illuminates.
Possible causes can be found in the
troubleshooting list.
Unlocking takes place by switching off and
then switching on again. If a fault shut-off
occurs during mixed operation (e.g. because
of empty gas cylinder) the heater continues
to run using electricity.
Electrical operation fault
If a fault occurs during electrical operation
the yellow indicator lamp (h) on the power
selector switch goes off.
Possible causes can be found in the
troubleshooting list.
If the 230 V power supply is interrupted for
short periods during operation the heating
will resume as normal.
Filling the water heater
1. Manually close the safety / drain valve
(Fig. A)
2. Switch on power for water pump.
3. Open hot water taps in kitchen and
bathroom, (set preselecting mixing taps
or single-lever fittings to ’hot’). Leave taps
open until the water heater has forced out
air and filled up with water and water is
flowing out of the taps.
Note: If just the cold water system is being
operated, without using the water heater, the
heater tank also fills up with water. In order
to avoid damage by frost, the water contents
must be drained by operating the
safety/drain valve, also when the water
