Truma warning light

[p3a2i7t8sy]

My truma combi thermostat glowed red . Had on during the night the outside temperature was normal for this time of year. After switching off and waiting an hour I switched on and the heating worked normally.I was using electric. Don’t now model number but it,s on our 2012 auto sleeper. Any advice on the probable cause would be helpful.

Thankyou

That said, it can be anything.

From low battery (even though you were connected to the EHU) to some fan issue.

Were you in electric-only or gas/EHU mix mode ?

You probably did a reset and it started working again.

I had this as well a couple of weeks ago,  it seems to be a safety feature that when the Truma gets to warm it shuts off and the red led glows.

Turning it off and waiting for it to cool down does the trick.
