Operating instructions

67
Select gas, electrical or mixed operation using the power
switch. Illumination of the yellow LED (G) on the power
selector switch indicates that the unit is operating with
230 V.
Move rotary switch on control panel to operating position
(N).
Set the rotary switch (H) to the desired thermostat
setting (1-5). The green LED (K) for operation is lit and
simultaneously indicates the position of the selected
room temperature. The yellow LED (P) indicates the
water’s heat-up phase.
The device automatically selects the required power
setting in accordance with the temperature difference
between the temperature selected on the control panel
and the current room temperature. When the room
temperature selected on the control panel is reached, the
heater switches back to the smallest setting and heats
the water to 60 degrees C. Once the water temperature
is reached the heater switches off and the yellow LED
(P) goes out.
Heating without water temperature monitoring.
Select gas, electrical or mixed operation using the power
switch. Illumination of the yellow LED (G) on the power
selector switch indicates that the unit is operating with
230 V.
Move rotary switch on control panel to operating position
(M).
Turn the rotary switch (H) to the desired thermostat
setting (1-5). The green LED (K) for operation is lit and
simultaneously indicates the position of the selected
room temperature. The yellow (LED) (P – water’s heat
up phase) will be lit only when the water temperature is
below 5 degrees C).
The device automatically selects the required power
setting in accordance with the temperature difference
between the temperature selected on the control panel
and the current room temperature. Once the room
temperature selected on the control panel has been
reached, the heater switches off. The warm air fan
continues to run at slow speed until the outgoing air
temperature (on the unit) has fallen to 40 degrees C or
less.
If the boiler is lled, the water will automatically be
heated at the same time. The water temperature is then
dependant on the heating output being given off and the
duration of heating required to reach the desired room
temperature.
Heating with drained water system.
Select gas or electrical operation using the power
selector switch. Illumination of the yellow LED (G) on
the power selector switch indicates that the unit is
operating with 230 V.
Move rotary switch on control panel to operating position
(M).
Turn the rotary switch (H) to the desired thermostat
setting (1-5). The green LED (K) for operation is lit and
simultaneously indicates the position of the selected
room temperature. The yellow LED (P) will be lit only
when the temperature of the unit is below 5 degrees C !.
Depending on the operating mode, the unit will
automatically select the required power level according
to the temperature difference between the setting on
the control panel and the current room temperature.
Once the room temperature selected on the control
panel has been reached, the heater switches off. The
warm air fan continues to run at slow speed until the
outgoing air temperature (on the unit) has fallen to 40
degrees C or less.
Switching off
Switch off heater at control panel using rotary switch
(position O). The green LED (K) goes off.
If the green LED (K) 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 (K) 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.
Fault
Gas Operation
If a fault occurs during gas operation the red LED (R) on
the control panel illuminates.
Please consult the Trouble-shooting list for possible
causes.
A reset (fault reset) is carried out by switching off,
waiting until all LED’s on the control panel have stopped
ashing and then switching the heater on again.
! If a window to which a window switch has been tted
is opened, the heater stops operating and the red LED
(R) ashes. The heater continues operating when the
window is closed.
Electrical Operation
In the event of a malfunction on the electrical mode, the
yellow LED (G) on the power selector switch goes off and
