Changing Heating Thermostat

Seagulls123

Hi all!

I have an old thermostat that has stopped working (doesn’t switch on / off based on temperature.

I bought a new one however the inputs for the wires are different.

Wanted some advise as to how the wires should be aligned to the new inputs or have I bought the wrong thing.

current set up( Honeywell) which has 4 wires;

Yellow and green
Blue
Yellow
Red

the new digital thermostat (Flomasta) has 3 inputs
NO
NC
COM

Thanks for all your help!

Current model is HONEYWELL T6360-1028.

New model is FLOMASTA 22199SX WIRED DIGITAL

You have provided insufficient information.

The colour of the wires is irrelevant without stating which terminal they go to on the Honeywell stat. e.g 1,2,3,4 Eth

Apologies I presumed colours were standardised .

Oh the Honeywell (current set up):

1 - Red
2 - blue
3 - yellow
Grene and yellow (has a symbol not a number) -similar to an upside down Christmas tree)

Cheers

Flowmasta connections:

Yellow and green - earth, not required, isolate in a connector block

Blue - neutral, not required, isolate in a connector block

Yellow - NO, demand

Red - COM, live

As you didn't know that was an earth symbol, perhaps calling in expert may be a safer option .... ?
