Secondary circuit - no thermostat?

[TimmyD]

There seems to be a secondary circuit for the central heating of the extension part of the house we moved into recently.
This means that when the wall thermstat in the living room is off the rads in the original part of the house turn off as you'd expect.
However, the extension part, which has three radiators, still stay on and the boiler continues to heat to its set temperature.
There is a secondary control valve for this circuit in the airing cupboard. There is no other thermostat in the extension.

Does this mean the only way to control the extension part is by adjusting individual rads in the extension?
And does that mean the boiler keeps heating to its set temp regardless?

Can I get a thermostat that talks to the secondary control valve?

Any help is appreciated!

You need to fit a wireless stat in the extension to control the heating there using its control valve.

Cheers Tony.
Does that mean I'd have two stats - the original in the old part of the house and a wireless one in the extension?

Being completely clueless aout wireless stats, does it get programmed to "see" the secondary control valve?

The wireless stat receiver is wired to operate the second valve.

Ok, thanks very much!

It would be normal to have a seperate timeclock or a programmable stat to control heating times.

Sounds like an unfinished installation.

You need a programmable room stat.

But that requires the valve to be correctly wired with the orange wire connected to bring on the boiler.
