Heater Temperature Changed To Fahrenheit

[c5 and mostly happy]

My heater display randomly has changed to reading in Fahrenheit. Last time it went back to 'c of its own accord but don't know how.

 

 When it does this - I also I lose heating backing lights.

 

The outside temp indication changes on the centre warning along with time, 12/24 hr and language but this has no effect on the inside temp indications.

 

Its not a real problem, just curious.

 

Thanks

I can change mine through the setup arrangement - time & date; 12hr or 24hrs etc.

Hi John,

 

yes I can change the outside temp as you say.  That's reading in 'c but heater temp is still  in 'f.
