HoneywellT6063 wiring

[Cat007077]

Help…
My Robus thermostat stopped working - light was on but not calling for heat. I removed it and took picture of wiring (see first image) and thought the wiring would be the same on the Honeywell T6360! Wrong!

The numbers did not match on wires - 5/6 has no screws in new fitment (see image2). Also the new fitting didn’t seem to need the link wire ‍ I found a lion here that suggested wiring but popped fuse. I then found another wiring diagram in here and the light came on but thermostat didn’t call for hear. I presumed I’d damaged the thermostat so got another one.

Before I botch this up ‍ can someone please advise on wiring - I have a brown wire , black wire with a brown sleeve on and a blue wire with grey sleeve on it….(see image 3)

Try:
Brown to 1
Black (oversleeved Brown) to 3
Grey (oversleeved Blue) to 2
Green/Yellow to Earth

The wiring diagrams for these units may be printed on the rear of the cover.

If this still doesn't call for heat, your original stat may not have been at fault and the issue could be elsewhere.

Thanks mate … will give it a try Original light on thermostat was flickering and calling for heat … so hoping it’s thermostat and not something bigger

Sorry grinch … this is one of 3 thermostats in my house … it controls upstairs heating and I have two downstairs to control underfloor heating. Would this make any difference to wiring?

No, it shouldn't make a difference to the wiring.
But it does increase the probability that the fault could be elsewhere!
