warmflow combi boiler

[gronko]

Hi there i'm looking for some advice regarding my Warmflow oil combi boiler, ModelC90HE
The hot water works ok but the central heating fails to come on line.
I have bled all the radiators and the pressure gauge on the boiler is reading 1-1.5 bar.
A friend who is a plumber believes it could be the diverter valve?
Does this boiler have a diverter valve, and is it likely to be this? and if so any ideas where i can get one?
Any advice is greatfully accepted as a cold house, two kids under 3 = one wife giving me a serious hard time!
Many thanks
Paul

After a pretty torid day have managed to volts check everything and all is ok.
The problem turns out to be the remote thermostat not cnnecting to the remote sensor.
The sensor and boiler are in the garage and programmer in the hallway.
If i take the programmable thermostat into the garage the two units 'connect' and the boiler fires up.
The thermostat had recent new batteries and i,ve changed them again but still will only work when units next to each other.
The unit is a T105 Sunvic progammable, do you have any idea if its best to change the reote thermostat or the receiver? if so could you recommend a local supplier? I am living just outside Yeovil.
Many thanks
Paul

I would change both for a different make or are they still guarenteed?
