l = Summer operation (water temperature
40 °C or 60 °C)
m = Winter operation (heating without water
temperature monitoring or with drained
water system)
n = Winter operation (heating with water
temperature monitoring)
o = Rotary "Off" switch
p = yellow LED lit "Boiler heat-up phase"
r = red LED lit, red LED blinking "Failure"
The LEDs are visible only when the unit is
switched on.
Note: The control panel, situated above the
entrance door must be switched on for the
combi boiler to operate. See page 69
Room thermostat
To measure the room temperature, the room
temperature sensor (See page 97) is fitted to
the furniture. The exact location is determined
by the layout of the vehicle.
The thermostat setting on the control panel
(1 – 5) must be determined individually
depending on the heating requirement and
the type of vehicle. For an average room
temperature of about 23 °C, we recommend a
thermostat setting of about 4.
Taking into operation
Heating is possible without restrictions with
gas, electrical and mixed operation, with or
without water.
Check to make sure the cowl is unobstructed.
Be sure to remove any covers that may be
present.
For operating on gas turn on gas cylinder and
open the shut off valve at the manifold.
For operating on electric operate the water
heater switch on the power supply unit. See
page 71.

Summer operation (boiler operation only)
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.
Mixed operation (gas and electrical) is not
possible in summer mode. With this setting the
unit automatically selects electrical operation
with a preselected power setting of 900 W or
1800 W.
Move the rotary switch on the control panel
to position (I – summer operation) 40 °C or 60
°C. The green (k) and yellow (p) LEDs light up.
When the selected water temperature is
reached (40 °C or 60 °C) the heater shuts off
and the yellow LED (p) goes off.
Winter operation
· Heating with 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 (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
°C. Once the water temperature is reached,
the heater switches off and the yellow LED (p)
goes out. The warm air fan can continue to
run in order to cool the unit (after-run).
· Heating without water temperature
monitoring
Select gas, electrical or mixed operation
using the power switch. Illumination of the
