Thermostat wiring help...............

[Baker1988]

Hi i have got a thermostat its a plumb center room thermostat and the instructions are not very clear i have a 3 core and earth at the point to connect it and this is the drawing.

I am thinking 1 live 2 neutral and 4 switch live but im honestly not sure

If it’s to control heating the lives switch between 1 and 3

 

[Baker1988]

Yeah it is for a combi boiler and looking at it again yes i think you are right 1 perm live and 3 switch live and 2 neutral thanks

I think a programmer/programmable room stat would be more appropriate if it’s for a combi boiler as how will you be able to set your heating with just a mechanical stat?

Boiler might have a built in timer. Like this one for an ideal logic for example. Ideal Logic 24 hour mechanical timer kit | Priority Plumbing - https://www.priorityplumbing.co.uk/ideal-logic-24-hour-mechanical-timer-kit-HC204839?gclid=EAIaIQobChMI6NvB2LSr2wIVorztCh31pAXKEAQYBCABEgKzq_D_BwE

How do you know that there isn’t a programmer already installed?

The same way you don’t know there is.
If there is then there is and my post isn’t relevant

Exactly, so why make a statement which is irrelevant to the question being asked?

Why are you bothered?
If not to be deliberately argumentative

 

[Baker1988]

No there is not a programmer already installed, i think it will be in the boiler but no boiler installed yet, its on a site i am working on there are 25 houses all woth the same in its all wired as to the specs basically a fused spur in the kitchen ring circuit and a 3core and cpc to the thermostat position and a 5 core to where the boiler will be next to it, its not the best design but its what my supervisor has said to do, i just was not sure about the wiring for the stat but having looked at it now i can see what it is but at the time my brain was just not working.

pretty sure on new build now you need at least 1 heating zone per floor so you would need two stats and valves for the heating controlled by a 2 channel programmer or programable stats

A site we work on has the house on 1 zone and ‘bedroom 1’ on its own separate zone.
Other sites have 1 floor on one and one on the other.
Always have a programmer in bedroom 1 tho if 2 zone
My home was built in 2014 and only has the one zone.

part l building regs
Every home must be divided into at least two heating zones. Living and sleeping areas (zones) must be controlled at different temperatures by means of a thermostat.
