thermostat with a small differential + anticipator?

[ShaunCorbs]

Hi ShaunCorbs,

I opened it, there are 3 wires, one is half green half yellow, another is blue, and a 3rd is brown.

so 2 wires as green / yellow is an earth

the problem you have is no neutral which takes a new stat range from + or - 5dc to + or - 1dc

you have three options

replace with a battery digital one or get a heating eng/spark to run a new cable 3 core + earth and fit a new stat

or the third get a rf stat fitted

in the correct place eg 1.5m from floor and if a rad is there no trv to be fitted just normal lockshield

think howsie is right...trv,s faulty..

Thank you v much ShaunCorbs,

I'll deal with it tomorrow. I guess a battery powered will be the easier and cheaper option, right? As I may be able to fit it myself?

And do these battery digital ones have a small differential? And anticipator? Don't anticipators require a 3rd wire, for the little "heater"?? Can a battery do that??

Cheers,

Mark

No you need a 3rd wire for an anticipator,

Should we be telling peeps how to do a sparkys job ? Could be 230v involved and possibly Boiler case removal

no boiler case removal needed as you can tell which is which at stat

but down to op and if he has a multi meter

But as I understood it, anticipators have a little heating element. Can a battery powers that? Wouldn't the (small) battery be drained in a few weeks, if not days?
