Hello

I am having to replace the unvented hot water system in my property, and as a temporary measure to get DWH downstairs I have un-isolated the supply from my Grant combi boiler.

But, no hot water is forthcoming! I think it may be a problem with the Danfoss set3e programmer which a builder removed and replaced during renovation works.

I have attached a photo of the wiring, and it looks to me if there should be a wire going into terminal 1 (Water-On) but which wire?

Hope someone is able to help!
