Ah right ! Assumed closed was closed . Now you’ve concerned me I’m tempted to stick my own sensor on flow and return . I can then shut the manifold pump and actuators automatically if flow temp is too high . That sounds sensible ? . My uvc ufh output is set at the minimum I think of 30 degrees . So if I auto shut off everything if flow exceeds 35 degrees - it would be a good fail safe ?

Reading through old threads on all this and blending valves - naturally confusing myself . Understand the suggested requirement for a blending valve as to stop water to hot ( due to boiler /ASHP etc . failure ) entering the ufh . ’puts neck under blade ‘ . With these self regulating actuators and the delta being greater than 7/4 degrees - the actuator would shut - preventing potentially damaging the slab due to over heating . Erm , ( hides behind sofa ) - that’s correct yes ? ??

Carpet ? ??

Yeah I think so . Did search the forum and found some other threads on the issue . Will experiment next week ? It was just strange that the return / flow on that zone were cold after a few hours - even though actuator was on .

I’ll do more testing Monday

That’s what i would assume . But that flow / return on the actuator zone was cold

Maybe . But I’m still confused ! ( not hard to do ) . It would seem actuator powered is zone off I.e pin down . But in that case pump should be off . or I’ve got this all wrong ( ? ) . Ignoring the clever delta stuff - power to actuator means zone on or off ....??

Not sure https://www.wundatrade.co.uk/shop/home/quick-shop/wundatherm-quick-shop/controls-quickshop/actuator-auto-balancing/

If you zoom in on my previous photo the flow regs can be seen

Not on site now . The caps are on but loose I.e pin is up - zones open So I guess I’m saying I need to power the zones for heating off ? - but shouldn’t the pump be off then ???

Dirty dog ! Too early for that

The packaging??

What I’m saying is with zero power applied the actuator pin is in ; so if installed zone would be heated . So powering it closes the valve . So I’m heating all of upstairs apart from the bathroom???

Oh you thick (expletive deleted) ! Of course ALL the valves are open ! But I assume if I turn off the only installed actuator ( bathroom ) - power off will close the loop . So no heating in the bathroom ?!

Flow and return pipes for this zone don’t seem particularly warm . I assume I should be able to feel the heat at this point ??

I think it’s meant for detecting earthquakes - so perhaps you are right ?

That doesn’t mean I’m right ! The aeon multi sensors are z wave devices . Can measure movement , light , humidity , temp , vibration and 1 other thing ?

No I read up on this and thought it was a bit pointless . I’m just testing 1 zone at the moment , the bathroom . If has aeon multi sensors in it - so I can read the room temperature there .

Assuming this all works correctly what things should I take into account to control the ufh . All done via software . Do I take the external temperature and use that to adjust the ufh ? Perhaps use occupancy of a room to activate ufh ( though its slow to heat so not sure about this ) Any other suggestions to take into account ??

Ok . I left it for 5 minutes- it’s now switched the pump on .

I’ve wired this up correctly I think ? Can turn my fibaro z wave relay on and off which in turn activated the actuator ( though I broke one of the clips !! ) Pump is wired off S1 ( L1 and N ) . But when I enable an actuator ( actuator flashing led as it calibrates ) the pump doesn’t come on . It has to doesn’t it ???

Oi @joe90 you took a vow of silence!!

Ffs ! I posted a link to help @zoothorn Not directed at you @Declan52

Reminds me of the girl behind the bike sheds telling me I didn’t understand

Ah ! Haven’t got one of those . I’d add to your can’t take a joke list Be a landlord Face bankruptcy Highly judgemental of people ( see point 1 ) Highly cynical of people ( see point 1 )
