DuoControl

Intended use

The DuoControl is a safety gas pressure regulation system with
automatic changeover for connecting to two gas cylinders
for caravans and motor homes. The gas pressure regulation
system provides a uniform output pressure of 30 mbar or
50 mbar (depending on the variant) with a permissible admis-
sion pressure of 0.6 – 16 bar.
Two high-pressure hoses are required for connecting the gas
cylinders to the gas pressure regulation system. Truma pro-
vides the high-pressure hoses that are needed for this in the
most commonly-used connection variants for European gas
cylinders (see page 66).
Even though it is not a mandatory requirement, Truma
always recommends the use of high-pressure hoses with
a hose rupture protection.
The use of the gas pressure regulation system is not permit-
ted in confined spaces (households, mobile homes), on sea-
going boats or in explosion protection zone 0 (e.g. tankers).
The DuoControl may not be used in commercial vehicles in
Germany (in accordance with BGV D 34).
The pressure regulating devices and hoses must be
replaced with new ones within 10 years of their date of
manufacture (every 8 years if used commercially). This is the
responsibility of the operator.
Notes on operating the gas system while driving:
With motor homes as of construction year 01/2007, in accord-
ance with the heating equipment directive 2001/56/EC with
annexes 2004/78/EC and 2006/119/EC for the operation of a
liquid gas heater while driving, a safety shut-off device must
be provided that prevents gas from inadvertently escaping in
the event of an accident.
For this purpose, Truma also supplies a version of the
DuoControl gas pressure regulation system with integrated
crash sensor (CS). In combination with high-pressure gas
hoses with integrated hose rupture protection (SBS), this
complies with all of the relevant standards, regulations and
directives and therefore allows the gas system to be used
throughout Europe, also while driving.
A safety device is also recommended for safety reasons if
caravans are being heated while driving.
For vehicles manufactured before 01/2007 there are no restric-
tions, and DuoControl can also be used for operating the gas
system while driving.*
The enclosed stickers (close gas cylinders while driving) do
not apply in this case.
* Exception for France:
In France the operation of a gas system while driving is only
permitted in type-tested vehicles with initial registration as of
01.01.2007. In older vehicles the operation of the gas system
while driving is also non-permissible in combination with a
safety shut-off device.
Gas cylinders that are not connected to the gas installation
must be closed at all times and provided with protective caps.
Connected gas cylinders are considered to be operating mate-
rials and not hazardous materials (ADR exemption in accord-
ance with sections 1.1.3.1 and 1.1.3.2 e).
