Wiring up new room thermostat

Former Community Member over 4 years ago

Hi guys

Hope you’re all keeping well and safe?

I need some help with wire colour identification for my new Flomasta and 6259G wired thermostat. I have worked on any heating/water installs yet, so I’m not familiar with the wiring colours. My old analogue Honeywell thermostat has 5 wires, Gn/Y, blue, black, light grey and brown. The Honeywell is wired 1 gn/y, 2 blue, 3 black, 5 brown, light grey isn’t used. New flomasta uses only 3 wires, Com, NO & NC, I know the NO & NC means open/closed, but which colour wire goes to which terminal?

but cold water is not direct from the mains in kitchen either.

Cold water to a kitchen tap MUST originate from the cold water main for health reasons. It should be mains pressure and not from a tank. It is drinking water.
