My son in law has a central heating system that doesn't appear to have a
thermostat. There is no thingy on the wall that you can adjust.

It uses a ACL Drayton LP522 control unit. Does this have a built in
thermostat or do I need to fit one externally?

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

There are no TRV,s in the system . The room just gets so boiling hot that
you have to turn the heating off.

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

or do I need to fit one externally?

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