Wiring up new room thermostat

Former Community Member

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?

    It may well have been a dual use design also able to last for a number of days as an emergency shelter in the event of a nuclear attack and or to store enough to put out fires nearby if the mains water was off..

    While it's a possibility, I do not think that much thought went into it. Some of the installation was over engineered but much of the building is typical 60's, throw it up minimum cost. The tank did not have a proper cover or insulation although it is above the boiler room and the hut on the roof had one slatted wall to allow the air and everything else in.
