I think, as far as that picture goes , he was trying to tell me that my copper feed pipes are too long and bendy ,my manifold should be assembled the other way around . I don't think its going to matter, other than look a bit odd . Its a tight spot under the stairs and to me the way i done it...

any one can almost do it

yeah I'm getting a headache . thanks for all your help .

anyway , ive run the bloody thing again ... put the mixing valve on 45c room temp was 22c put 24c desired on the hive thermostat and watched what happened (this time i closed the windows) click! things come on pump zone valve open live goes to actuators i still cant see movement, after a minute...

i'm looking and looking but just not seeing it . its really obvious isn't it ! .......looking+looking ........... no its just not jumping out at me . I'm too thick ! do i have the wrong mixer valve ? is it that all my plumbing is back to front and i should have assembled the manifold pump...

you mean an overheat thermostat ?

thats what i was trying to deal with , but my poor brain just couldn't fathom it out . the wiring diagram doesnt go far enough to explain its relays and what they are supposed to switch . anyway im probably in dire need of professional help on many levels at this stage .

AAAHHHH thank you Roger thats really helped me get a clue :) so ive got a zone valve so the actuators can go (as its all 1 zone) and the wiring can stay as is , all be it a bit more tidy .

ok ive had a look , what ive done before is ok for just simple switching of pumps, valves and old boiler with just L.Eand N going to a chock block . that was just about within my capabilities or not , but its done and works to a point . I wasnt able to figure out how to connect the wiring...

they don't move , they are just open or is that closed as they are NC ? . the return gets hot so i assumed they open . hmmm? that's got to be one of my problems , thanks ill need to rewire the wiring centre and see if i can get them going .

1st hive unit switches ufh and hw zone valves its a hw cylinder rads upstairs thermostatic valves on zone valve with another hive for them its a heat only boiler . Its 3 seperate zones s plan Ill have to go and watch the actuators to be 100% , but they do open or stay open at least . ill get...

they are NC https://www.theunderfloorheatingcompany.co.uk/product/thermal-actuator-head-230v/ they are connected to the circuit board where they are supposed to go , they must be getting a feed as they do open . Its amazing I've got this far ,so i accept your gasps of disbelief along with...

a hive thermostat measuring air temp controls the boiler

yes they are 240v if thats what your getting at ? and all i have is Hive

wiring is just stuck in there any old how atm just to try and get it ON a few loose ends to say the least overheat thermostat wire dangling about waiting to go somewhere ive yet to figure out . i need a miracle . or an electrician
