Hi Charnwood, Thanks for the advice and link. I'd established it would need a york flange but can only source 1" versions. Am I right to assume that as the threading on the tank (measured with a calliper ruler thing) is defiantly 1.25", I will need to source a male to male reducer for a York...

Hi, Sorry to ask out of the blue, especially as your post is now three years old, but I was wondering if you'd resolved your query re the york flange to attach to your HW tank. I've got the same issue and am struggling to find a solution, which we need until the boiler and tank get...

Hi Guys, Apologies for the delay but many thanks for the extra info. Matt1e - thanks for the diagram of the altered wiring. It'll save me a lot of stress figuring it out. Seco, If the motor has stopped is it still just a csae of replacing the Drayton MA1 unit, or are you refereing to a...

Hi seco, Sorry for the delay - multimeter packed up! On CH only I'm getting 247V of the White and grey leads but only 2V off the orange. The picture IS of my unit, not one from the web. Any ideas what the fault is? Cheers, matt

I'll check and run the test you've suggested when I get home. I do have a mulitmeter but am definately not an electrician - if you can tell me what setting and what I'm looking for I'll probably be able to muddle through it. I'll update once I've checked. Cheers, matt.

Seco, I'm at work but think this picture shows it well enough - it appears to be set as in your example. Would you agree? Cheers, Matt.

Hi Seco, Sorry - my mistake for not thinking of white printing black in CAD! To confirm the Drayton wiring is (to left side): black wire to second terminal block, earth to third terminal block, white to fifth terminal block, grey to seventh terminal black orange to eigth terminal...

Hi all, We've recently moved into a "new" propoerty with an indirect vented hw/ch system. It currently has a cylinder stat but no room thermostat. The programmer is a fairly modern Landis & Staeffa (Seimens) RWB9 unit. Currently I have the CH programmed to run longer than the HW in both...
