FrostControl(Combi heating system only)
FrostControl is a non-electric safety or drain valve. If there is a risk
of sub-zero temperatures it automatically drains the content of the
boiler via a drain outlet.
If the system is under excess pressure intermittent pressure equa-
o lisation will automatically take place via the safety valve.
k Rotary switch position "ON"
m Push button position "CLOSED"
n Push button position "DRAIN"
o Drain outlet (to the outside through the vehicle floor)
To activate
• Push in the knob at position (m) slightly and, at the same
time, move it 90° towards position (k).
• If the switch is in position (k), the knob will remain in position
(m).
To deactivate
• Turn the switch at position (k) by 90° so that it is parallel to
the frost control.
• At the same time, the knob will jump from position (m) to (n).
The drain valve can only be closed manually using the
push button (Position m) and the boiler filled if the valve
temperature is above approx. 7°C.
If the temperature of the safety/drain valve is lower than
approx. 3°C, the push button will pop out (Position n)
and the contents of the boiler will be emptied via the
drain outlet (o).
The heated area is located in the central walking area of the floor. It is
60 cm wide. It serves not only to heat the room, but also reduces the
loss of heat via the floor. The length depends on the type of vehicle.
To turn on the 24 V floor heating
You will find the switch on the service panel. The floor heating only
works when the caravan is connected to the 230V mains supply. It
heats self-sufficiently. To use the electrical floor heating system, it is
not necessary to switch on any further heating devices.
Technical data
Voltage 24V~ from its own 230V/24V transformer.
Depending on the length of the caravan, power consumption lies
between 150W and 320W.
To prevent heat build-up in one spot, do not place
objects for a long period of time on the floor heating.
Do not drill any holes in the floor or screw in any screws.
