In my experience, thermostats without a neutral do not function very well!If you’re referring to the blue as a neutral then it only matters for temperature swings
They work, just with massive temperature swings as I said.In my experience, thermostats without a neutral do not function very well!
Try switching 1 and 3 around first. You need to know if neutral is connected at the other end otherwise it’ll do nowt.Thank you guys
The blue is neutral
Shall i try putting this in first or switching 1 and 3 around?
Just found this, which seems what the OP is suffering: https://support.esicontrols.co.uk/f...er-temperatures-and-on-at-lower-temperatures/The wiring as shown in your photo looks right to me. Assuming that it is a T6360B. The model number and diagram will be inside the lid. For it to work in reverse I would expect terminals 1 & 4 to be connected, and not 1 & 3.
In any case swapping the wires in 1 and 3 over won't do anything to correct reverse operation. The thermostat is just an on/off switch and the two wires in 1 and 3 will still be electrically connected together by the switch regardless of which way around they are connected.
For it to work in reverse I would expect terminals 1 & 4 to be connected, and not 1 & 3.
