Frequently Asked Questions
Q: How do I reset the reset button if it has triggered?
Using the screw aid's T20 Torx pin, press the black reset button into the housing and turn it gently anti-clockwise until it engages.
Q: Can gas appliances be operated while driving?
No, because the MonoControl does not have an integrated crash sensor to prevent uncontrolled gas escape during an accident in accordance with UN-ECE regulation 122.
