Where's the thermostat?

Some systems rely on TRVs on the radiators to control room temperatures.

The LP522 is a heating & hot water programmer timeswitch and doesn't incorporate a thermostat. He probably has TRVs on each radiator. If not, it's almost certain that a thermostat can be connected to the boiler.

Can you turn down the heating output on the boiler? I don't think I've ever seen a boiler without a main thermostat on the front of it.

Sounds like a crap installation and whoever did it didn't understand what they were doing. It could so easily have been much better.

Thermostats are cheap - wireless one is easy to fit.

That would work as a rather crude work around until a stat is fitted. Though I am suprised that there isn't one with no TRV's. No stat and TRVs everywhere is quite common, it's only recently that building regs changes have prohibited such installtions.

Fitting a stat is simple particulary if you choose a programable and wireless model.

And the boiler manual should show you where the connections go

no, it's purely a programmer

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "Sam Farrell" saying something like:

Many cheapskate bastards fitted CH systems with no stats, relying on the boiler stat to do the work. Horribly wasteful, imo. Easy to update, though.
