Truma MonoControl CS
The Truma MonoControl CS is a safety gas pressure regulator with an integrated crash sensor designed for operating liquid gas systems in caravans and motorhomes. It reduces the up to 16 bar cylinder pressure down to a 30 mbar operating pressure and automatically shuts off the gas supply in the event of an accident.

Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
Operational Fault | Possible empty cylinder, closed valve, triggered crash sensor, or closed quick-acting shut-off valve. | Check the fill level of the gas cylinder, ensure the cylinder valve is opened, check hose rupture protection, verify if the crash sensor has triggered and reset if necessary, and check that appliance quick-acting valves are open. | DIY Safe |
Regulator icing up | Temperatures around 0 °C can cause the regulator to freeze, reducing or interrupting gas flow. | Use an optional Truma EisEx regulator heater for a reliable gas supply at low temperatures. | DIY Safe |
Operational Fault | Possible gas leak or damaged connection. | Do not switch on any electrical appliances or other sources of ignition. Close the gas cylinder valve, have the gas system repaired by experts, and do not open the valve in the meantime. | Professional Intervention Required |
Operational Fault | The crash sensor has triggered due to an impact or manual operation. | Firmly press the yellow reset button, turn it slightly clockwise, hold for 10 seconds, and ensure it remains in the 'ready' position. | DIY Safe |
Gas system shows leakage | Possible leak in high-pressure or low-pressure gas lines or connections. | Close the cylinder valve immediately, do not open it until repaired, and have an expert repair the gas system. | Professional Intervention Required |
Operational Fault | The integrated crash sensor has tripped. | Continuously press the green reset button on the MonoControl CS for approx. 5 seconds. | DIY Safe |
Frequently Asked Questions
Q: Can I operate gas appliances while driving?
Yes. Thanks to the integrated crash sensor (safety shut-off device) compliant with UN/ECE regulation 122, type-tested liquid gas heaters and other gas appliances may be operated while driving throughout Europe (observing national regulations and special exceptions such as France).
Q: How do I reset the crash sensor?
Press the yellow reset button into the housing using the T20 Torx pin of the screw aid, gently turn it in a clockwise direction, and hold it for 10 seconds. Ensure the reset button remains engaged.
Q: Who is permitted to perform a leak test on the low-pressure section?
Only qualified and trained experts are permitted to perform leak tests on the low-pressure section of the gas installation.
Q: Can I operate my gas heating while driving?
Yes. The Truma MonoControl CS includes a safety shut-off device (crash sensor) that complies with UN ECE Regulation R 122, allowing the operation of tested liquid gas heating systems while driving throughout Europe (observe national regulations and exceptions such as in France).
Q: Can I operate the gas system while driving?
Yes, provided the vehicle is equipped with a safety shut-off device like the MonoControl CS, compliant with UN/ECE Regulation R 122.
