Baxi 133 HE Combi Boiler - Room Thermostat ?

[perm]

Hi,
Please Help......

I have a Baxi Combi boiler (133 HE) (7 months old). The boiler has a 12h built in timer. The house does not have a thermostat so how does this boiler know the temperate is correct in the house and to switch off ?

Some of the radiators have TRVs but not all.

I am confused.....

Thanks

quite simply it doesnt the ones with trvs will shut off but the other ones wont they will just keep going
I would personally put TRV's on the Rad's without them sorted

OK. I have another thread that talks about this situation........

Would it be worth looking into Baxi Intellisat addition ? Does this add any value ?

Cheers

the Intellistat is a very clever bit of kit which in the long run would save you money on your gas bills but it is also quite complicated to use and i would avoid unless you are good with electronics
