So i’m quite confused now, as i pulled the thermostat off the wall and it was still on, but had a 4core power cable going to it also. So are the batteries just a back up? Also I didn’t see any low voltage cables so does this mean it’s a wireless unit? Where would i find the receiver?
It doesn’t say anything about it, I can’t find any troubleshooting information anywhere! I think it’s wired not the system but not powered by it, because when i turn the mains off to the heating system the thermo is still on.
My Danfoss tp5000si display has all of a sudden stopped displaying the time and intstead shows only 2 dots flashing where the time normally is and also the temperature, which when i first looked was down at 5c. I moved to temp upto normal 20c and it switched on and the heating came on as normal...
