Wiring up new room thermostat

Former Community Member
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’s a built in shower with a hot/cold mixing tap in the middle, we had the same problem in our first rented property 19 years ago with a combi boiler, if some one flushed the toilet, the shower temp would rise as the cold water was refilling the cistern, but not to point where it’s scalding hot.  It’s the same sort of mixing you would get if you had used one of the old fashioned hoses on each tap, you just adjust the lever to cold or hot, dependant on what you like, me personally, I like really hot showers, I usually look like a lobster afterwards, but it’s really refreshing, especially on my back to ease any pain (getting old now ?).  I’ve just found a YouTube video on how to increase my boilers pressure, so I’ll give that a go tomorrow.   Thanks for you concerns though.  


    My brother used to have the same problem too, when the toilet was flushed whilst in the shower.  ???
