The Truma cp control panel on my 2016 Sterling Eccles has lost the electrical heating symbol on the fuel source options, ie gas, mix, electric 1 &2. I have the gas symbol but it just jumps over where the double electric should be
The boiler will work on gas but not on battery or EHU. The 230v symbol does show in the bottom right so power is there.
Checked both fuses, ok
Long conversations with Truma resulted in me buying and trying a new data cable that connects circuit board and control panel, no joy.
Then they offered to test both the control panel and circuit board in their workshop, but both are OK with no faults. I am awaiting their safe return via Royal Mail. They have no new ideas and suggest I get a Truma qualified engineer to look at it, earliest date available is July.
I am hoping for a simple solution like a reset button or procedure.
Anyone had this problem before and how was it fixed.
