I have the above unit for a glow worm boiler.

For some reasom (someone might have touched it!) there is an amber light on the wall unit alongside the boiler.
The green light is on. The hot water is working fine. The heating isnt coming on.
Do I have to reset the unit?
The manual online doesnt explain what the amber light indicates.
Many thanks

Do you have a pressure gauge on the heating? The pressure needs to be about a bar for the heating to work. Don't know what the amber light means
