I've had Evohome installed for several years, its worked really well after the troubles around set up and the password glitch that caused my controllers to crash when clearing the fault log. Anyway moving on, I still get lots of faults in the log and displayed on the screen but just ignore them unless they relate to batteries as the system seems to work okay regardless. Recently however the HR92 in the bathroom zone permanently displays E2 on the screen. Ive established this is an error and attempted the battery out reset method, which seems to work initially but it then comes back.
How do I clear this error or is the unit knackered?? Oddly it reports the current temperature and to the base correctly but when heat is called for by exceeding the current room temp either by local override or by increasing the zone temp at the base it does not call for heat at the boilew despite showing as much on the base. Current temp will show 15 degrees for example with displayed request at 25 degrees, boiler does not fire.
I actually only need this thing to act like a room stat as the towel radiators come on whenever there is a heat demand, they do not have a individual TRV.
So in summary, can I clear this fault somehow and is it possible just to use the HR92 as a room stat for temp measurement and local override?
