Heatmiser UH8-RF wiring centre UFH heating actuator wiring

microways85 · 13 Oct 2024

Hi

Please help look at my wiring . Usually the ufh actuator connection to the zones in the wiring centre is straightforward L and N . But I have a grey coloured wire on one of the zones . Is this done correctly and what is this grey wire for ? The zone comes on as usual when I fire up with the thermostat . But I rather pick up a potential issue now before it becomes a problem.

Thanks
