Heating mode

In heating mode the appliance automatically selects the
required operating level according to the temperature differ-
ence between the temperature set on the control panel and
the current room temperature. If the water container has been
filled, the water is automatically heated as well. The water
temperature depends on the selected operating mode and the
heater output.
All 3 energy selection options can be used for.
– In gas mode the appliance automatically selects the oper-
ating level that is required.
– In electric mode output of 900 W (3.9 A) or 1800 W (7.8 A)
can be manually preselected in accordance with the fuse
protection at the camp site.
If more output is required (e.g. heating up or low outside
temperatures) gas or mixed mode should be selected so
that enough heating power is always available.
– In mixed mode 230 V electric mode is preferred if the
power requirement is only low (e.g. for maintaining the
room temperature). The gas burner is not enabled until the
power requirement is higher, and is the first to switch off
during heat-up operations.
Hot water mode
(with filled water container only)
Gas mode or 230 V electric mode is used for hot water
preparation. The water temperature can be set to 40 °C /
ECO* or 60 °C / HOT*.
* ECO, HOT only with control panel Truma CP plus.
– In gas mode the water is heated at the lowest burner set-
ting. Once the water temperature has been reached, the
burner switches off.
– In electric mode output of 900 W (3.9 A) or 1800 W (7.8 A)
can be manually selected in accordance with the fuse pro-
tection at the camp site.
Mixed mode is not possible. With this setting the appli-
ance automatically selects electric mode. If the 230 V
power supply is disconnected or fails, the heater automatical-
ly switches over to gas mode.

Operating instructions

Read the safety instructions and operating instructions
carefully before starting the appliance.
Operating instructions can be viewed in offline mode
with a mobile device and the Truma App. Download the
operating instructions when you have a WiFi connection and
save them on your mobile device.
Before initial use, be sure to flush the entire water supply thor-
oughly with clear water.
The materials of the appliance that come into contact
with water are safe for drinking water (see Manu-
facturer's Declaration, www.truma.com – Manufacturer's
Declaration)

Control panels

The control panels are described in separate operating
instructions.
The temperature setting on the control panel depends on per-
sonal heating requirements and the design of the vehicle, and
must be determined individually.

Room temperature sensor

To measure the room temperature, an external room tempera-
ture sensor (2) is located in the vehicle. The position of the
sensor is determined by the vehicle manufacturer depending
on the vehicle model. More information can be found in the
operating instructions for your vehicle.

Safety / drain valve

A. FrostControl
(Safety / drain valve with integral frost protection / optional in
the UK version)
FrostControl is a currentless safety / drain valve. When there
is a danger of frost, it automatically drains the contents of
the boiler through a drainage socket. If excessive pressure is
present in the system, pressure will be automatically intermit-
tently equalized through the pressure relief valve.
