  If the Truma Control Panel displays error code E 2 H E 16 H, it means the flame was not detected. This could be due to an empty gas cylinder. Replace the gas cylinder. It may also be that the gas cylinder or quick-acting valve in the gas supply line is closed. Check the gas infeed and open the valves. High butane concentration in the gas cylinder may be the cause. Use propane instead, as butane is unsuitable for heating, especially below 10 °C. Finally, the combustion air infeed or exhaust gas outlet might be blocked. Check the openings for any dirt (slush, ice, or leaves) and clear them.

  The W 255 H error code on your Truma Control Panel indicates that the heater isn't receiving 12 VDC power or there's no connection between the heater and the control panel. First, ensure that the 12 VDC power supply is active. Next, verify and establish the connection between the heater and the control panel.
