Hi all...help!!

So I have a wirless drayton digistat scr connected to a valiant boiler. The
thermostat is working (new batteries) and is telling the receiver to
turn on
and off the boiler. Relay seems to be working inside the unit as I can
hear a
click and green light appears.
I can't overright the boiler to force on with the top over right button
(does
nothing).

When the thermostat gets to optimum temperature the green light goes off
but
the boiler stays on.

Problem is we moved in recently so we will never know if it used to work
correctly.

What's your thought?



We need to know a bit more about your system. Does the boiler heat the
radiators *and* a cylinder for the domestic hot water? Are there any
motorised valves in the system? If so, how many, and what type - i.e. 2
or 3 port?

If you could post[1] a few photos showing pipe arrangements in the
vicinity of the boiler and in the airing cupboard (if you have one)
together with any motorised (zone) valves, we'll be in a better position
to help you.

[1] You'll need to upload then to somewhere like Flickr (unless you've
got your own website) and post a link here.
