Hi,
I'm trying to install a Nest Thermostat E but I can't get it to work properly - it always calls for heat. Its replacing a Danfoss RMT230 wired like this:
I wired in the Heatlink following the guide on this page:
https://support.google.com/googlenest/answer/9247634?hl=en-GB
Where it says terminal 1 on the Danfoss goes to C on the Heatlink, and terminal 2 goes to NO, so the Heatlink is wired in like this:
The old programmer is set to 'On' for Central Heating. Its a Danfoss FP715.
If I put the old thermostat back in the CH turns on and off depending on the temp setting as it should.
If I disconnect one of the wires from the Heatlink the CH stays off.
I've factory reset the Heatlink and the Thermostat E and re run the installation process, but it made no difference.
Any advice would be very gratefully received as I've no idea what to try next! Thanks for reading!
