Operating instructions
Read the safety instructions and operating instructions
carefully before starting the unit.
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
thoroughly with clear water.
The materials of the appliance that come into contact
with water are drinking water safe (see manufacturer
declaration: www.truma.com – Manufacturer Declaration).

Control panels

The control panels are described in separate operating
instructions.

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.
Figure 2
The temperature setting on the control panel depends on per-
sonal heating requirements and the design of the vehicle, and
must be determined individually.

Safety/drain valve

A. FrostControl
(Safety/drain valve with integral frost protection / optional in
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.

Opening the safety/drain valve
– Turn the rotary switch by 180° until it engages, whereby the
pushbutton pops out (position c). The water from the boiler
drains through the drainage socket (d).
The FrostControl drainage socket (d) must be free of contami-
nation (slush, ice, leaves, etc.) at all times so the water can
drain out easily! No claims may be made under the war-
ranty for damage caused by frost.
Closing the safety/drain valve
– Check whether the rotary switch is set to "On" (position a),
i.e. parallel to the water connection and engaged.
– Close the safety/drain valve by pressing the pushbutton.
The pushbutton must engage in position (b) "closed".
Only when the temperature at the safety/drain valve is above
approx. 7 °C can it be closed manually with the pushbutton
(position b) and the boiler filled.
Truma supplies a heating element (part no. 70070-01) as an
accessory, which is inserted into the FrostControl and fixed
in place with a retaining bracket. This heating element heats
the FrostControl to approx. 10 °C when the Combi is switched
on.This means that the boiler can be filled sooner, irrespective
of the temperature in the installation compartment.
Automatic opening of the safety/drain valve
If the temperature at the safety/drain valve is below about
3 °C, it will open automatically and the pushbutton pops out
(position c). The water from the boiler drains through the
drainage socket (d).
B. Safety/drain valve
(Safety/drain valve without frost protection /
standard in UK version)
The safety/drain valve automatically equalises the pressure in
the event of overpressure in the system. When this occurs,
the water is drained to the outside in intermittent bursts via a
drainage socket.
This safety/drain valve does not protect the water con-
tainer from frost damage.

Opening the safety/drain valve
– Move lever to position (c) – vertical. The water from the
boiler drains through the drainage socket (d).
The drainage socket (d) of the safety/drain valve must be free
of contamination (slush, ice, leaves, etc.) at all times so the
water can drain out easily! No claims may be made under
the warranty for damage caused by frost!
Closing the safety/drain valve
– Move lever to position (a) or (b) – horizontal.
