9.2.4 Truma Combi hot-air heater D
Operating modes All heaters have two operating modes:
z Winter operation
z Summer operation
It is only possible to heat the vehicle in the "Winter" operating mode. With the
"Summer" operating mode only water in the boiler is heated. It is not possible
to heat the vehicle in this operating mode.
Selecting operating mode:
 Set the operating mode using the rotary switch (Fig. 195,3).
The power supply of the heater cannot be interrupted by means of the 12 V
main switch.
Winter operation The heater selects the necessary burner setting according to the required
room temperature. When the required room temperature is reached, the
burner is switched off. The room temperature is measured by the temperature
sensor next to the panel. In "Heater and boiler" operating mode (Fig. 195,6)
water in the boiler is also heated. In the operating mode "Heater without boiler"
(Fig. 195,5) the heater can be operated with an empty boiler.
Switching on:
 Turn the temperature control knob (Fig. 195,1) on the operating unit to the
desired temperature range.
 Set rotary switch (Fig. 195,3) to winter operation "Heater without boiler"
(Fig. 195,5) or to winter operation "Heater and boiler" (Fig. 195,6).
Green indicator lamp (Fig. 195,7) comes on and indicates at the same time the
selected temperature range.
X Take the device out of operation by removing the fuse and contact cus-
tomer service if one of the following events occurs: Long lasting, strong
development of smoke; unusual combustion noises; smell of fuel; con-
tinuous fault shut-down with error message (blink code).
Z The heater is powered with diesel fuel from the fuel tank of the base
vehicle. The heater is not approved for operation with biodiesel (PME,
RME, AME).
Z During heating, do not empty the fuel tank down to the reserve mark of the
fuel gauge in order to avoid air entering the supply lines.
Z Operate the heater every 4 weeks for approx. 10 minutes in order to pre-
vent a blockage of moving parts.
Z If there is a risk of frost and the heater is not in operation, empty the boiler.
