Tried that and it doesn't work.
The small flame signal comes on the controller but the boiler doesn't fire up.
Replaced the batteries in the controller as well just incase they were run down.
If I only need to use 2 connections on the boiler how come there are 3 ?
Thanks
Hi there.
New to the forum but I have the above valiant boiler. I have bought a new stat which is a drayton digistat 3 wired version.
I know the boiler has the connections 3 - 4 - 5 for an external 240v.
The stat has 3 connections common - load on - load off.
I am familiar...
