Wiring for Center RF Wireless Thermostat.

Neil Stevens · Tuesday at 6:20 PM

I am wiring a thermostat into my combi boiler. The live brown and blue neutral I am fine with. I can see from the wiring diagram that the two terminals A and B on the receiver box are used. There are two wires from the boiler coloured black and grey. Which goes to which? I understand from what I have read that T1 (call for heat) is the black wire and T2 (return) is the grey but I wanted to be absolutely sure.

Thanks

I read too that as it's a low-voltage set up, it doesn't actually matter which way they are connected....

A lot depends on which boiler you have some use mains voltage on the thermostat some are low voltage

If the boiler is compatible with the Opentherm technology then the Wiser could run the boiler with that
