Boiler problems in new house!

[doddym]

Hello,

Ive just moved into a new house which has an older boiler installed.
It is a Glowworm Ultimate with a Lifestyle LP112 programmer.

I cannot get the central heating to switch on by itself, it will only operate if the hot water is also switched on at the same time.

If i switch on the central heating by itself the boiler does not even attempt to start or fire up.

The hot water always fires up first time - no probs there.

There does not appear to be a 'y' valve in the airing cupboard.

There are four pipes going in/out of the boiler.

Any advice would be most appreciated

TIA

Yep - all the way!

can you hear a click when you turn it up and down?

 

[doddym]

Yes - & it has an indicator lightthat activates....

 

[diesel_ltd]

ok this is good
is your pump in the hotpress?

The pump is upstairs in the airing cupboard (hotpress) It works fine aslong as the hot water is switched on too.

ok under the pump there should be 2 gray boxes on the pipes these are motorized valves one is for heat other for hot water is this true??

Definately sounds like a controls issue. Very difficult to diagnose without actually looking at it.

Hi Diesal,

difficult to see, but it looks like a std pump with pipe in one side, out the other & a power cable going to a fused spur. I can't see any grey boxes on the pipes. Its v low to the airing cupboard floor partially hidden by a shower pump.
