@nod did you move the faceplate and the backing plate? I know my 12v ones are 2 part. As @dpmiller says power comes from the wiring center and is independent from the actuator.

power comes from the wiring centre.

Large amount of guess work going on but I would imagine (hope)..... ASHP heating the water cylinder (thermal store?) in the low 40’s for max COP. Cylinder possibly acting as buffer for UFH. Cylinder passing pre-heated water to Sunamp for DHW delivery. (Sunamp being charged by solar where available).

Got tired of using fan and halogen heaters. So plumbed a Willis into the main manifold and got some circulation to the upstairs loop, which covers the landing/balcony, the big bathroom, and the ensuite. I couldn't quite get enough flow through the willis just by closing the bypass over so it's duty cycle was a bit low; conveniently I was able to set a length of 15mm copper into the end of the bypass pipe (vertical, to the right of the pump )to force flow down into the cold end of the immersion. Much Better. Got the loop up to 23c return temp today and the house did feel a lot warmer for it.

Merry Christmas everyone and I hope all your dreams of self build come true. This is our second Christmas in the new house although I think it’s more liveable now! The last few months have been spent getting it that way, it now resembles a home, all rooms are more or less finished although we will be revisiting the dining room next year and trying to get something done with the staircase whether it be moving it to the position it should have originally been in had it not been short of around 40mm headroom and wouldn’t pass regulations or starting again with a new one! However this will wait until the garage is finished, it’s up and the roof trusses are on we just have to get some time to finish it off, we got a fantastic bargain of a up and over garage door, 4.3m wide from a chap who was in a new build and was changing his garage into living accommodation-£30! He had been advertising it without any luck and I just happened to spot it on gumtree just after he’d reduced it because he just wanted it away! Made to measure for us . Next year will also see the drive getting done, it’s only hardcore just now, and after that a proper holiday will be called for! I almost forgot about the front door where we decided disabled access should be , our one and only visit from building control brought up the fact that the door , being one of these two half doors , wouldn’t be suitable for disabled access as it only has a handle on one door, the other being opened with two little bolts top and bottom which could not be accessed by a wheelchair user, our own fault, we were meant to have the access at the back door but we would have needed quite a long ramp so decided on the change without giving the actual door much thought. I don’t like the existing door anyway so we will source another in due course, we can’t get off a temporary habitation certificate anyway until the garage is completed so all things to work towards! I’ve been up since 5.30 this morning as I had to have one of the dogs operated on yesterday and with 10 people for dinner it’s going to be a long day! I hope you all have a good day whatever you’re doing.

Yep I love our kitchen sink I also loved the three others my wife chose prior to settling on this on some kind stone resin Try hard waring doesn’t scratch Blanco

Did you try a known good stat on the suspect location? Perhaps no power to that stat position? Caution some Heatmiser stats are 12V and some 230V. See if there are model numbers on the back. Google and download the manual which have wiring diagrams. Check which pins should have power on them.
