See pic. Current 3 port is a sunvic dm5601.
No grey wire on existing just orange, white, yellow, blue and earth?
Will a honeywell be able to be wired up here? I can't find a wiring guide for this model of sunvic.
Good evening everyone,
Question 1
I have just replaced my 3 port motorised valve head and wired it in.
When looking at my chocolate block connector the orange and grey wires are in different places than the diagram on the instructions shows.
As you look at the terminal block for all the wiring...
G'Day fellers. Appreciate your help please:
When my boiler fires up it heats the water and radiators regardless of what is selected. I'm guessing that this means the valve is not moving from the de-energised position?
Its a Honeywell V4073A. The manual/auto lever moves freely both ways and...
Hi guys,
Two questions I am hoping you can help me with.
1) My Danfoss HS3 motorised actuator has a rest position of B hot water as I found out is normal. Once I put the central heating on the valve winds fully to A again as expected but once the CH has been turned off the valve remains at A...
Hi guys.
Hoping for a quick Three port answer.
When wired to programmer tined switch?,is this the common wire to cylinder stat??.
As what I'm trying to retrieve is when the water is used and goes below set temperatures to fire up boiler.
Just trying to get heads up about the wiring again.
This...
Afternoon Lads and Lasses. I am setting up a 2 circuit UFH system the manifold has 3 ports. Do I blank off the spare ports or do I fit a loop and leave it turned off ? The other ports will be controlled with room stats.
Hi. I'm new to all this, and not sure it's appropriate, so be gentle with me.
This flue is to my newly fitted replacement Ideal Logic Max boiler. The position is the same as it was with my old boiler. I have been told in the past that it was incorrect, but my fitter has assured me it is now OK...
Had a couple occasions where roomstat was calling for heat but boiler wouldn't fire. Wiggled the head on the 3 port valve (Drayton MA1) and the lever would then move from M to H, there'd be a click, the pump would come on and the boiler would fire. Actually on both occasions it looked like the...
Are 2 port valves necessary on the flow of heating if a underfloor heating manifold is used such as this one in the picture? As far as i was aware the manifold acted as a valve.
Thanks
My Altech 010 seized (motor & valve), so I ordered another off eBay.
After it arrived, I removed my duff one, and when I opened the new box it was actually a Salus!
Not the end of the world I thought, so I swapped over the valves, but now I'm connecting the wiring, there's one white wire left...
Why does my heating only work when hot water is satisfied, the motorised valve only opens when hot water is up to temp when I turn up cylinder stat valve shuts again. Worked ok for long enough wondering if its the synchron motor but it seems to open valve ok when hot water is satisfied.
Are there any 3 port motorised valves (preferable cheap) that do not require a constant mains current to flow when the value is either open or closed (ie it just needs current while actually opening or closing)?
I'm trying to cobble together something for a small diesel heater to be used in a...
Hi I was wondering if any of you kind people have any old two port valves they wouldn’t mind cutting the cable off and posting me? I would obviously cover any costs..... I want to make a rig up so my apprentices can get familiar with wiring S-plans. I know I could just get some 5core but the...
Hi,
I have a fault with my CH that has only started in the last few days and its driving me mad.
My system is set up as follows - CH, HW and UFH.
There are two port valves on each and they all work independently.
CH stat is Salus RF, UFH is Polypipe again RF.
Programmer for CH & HW is Honeywell...
I have a Camray 5 90 external combi oil fired boiler. I replaced the 3 port valve body only as it was leaking and after that seemed to work ok. However shortly after when CH was being called for the accuator wasnt moving and had to manually be moved to man position to get CH. However the other...
Evening All,
I changed a Drayton three port valve today as the valve was completely seized. It appears to be wired correctly. When I switch to HW it moves to HW and when I switch to Mid it moves to Mid. But when I switch to Heating it clicks repeatedly, the small lever on the actuator stays in...
Hi,
I bought a house last (built 1988) which had a 3 port valve (Honeywell V4073A), a vented cylinder and 2x tanks in the loft. I had a plumbing company remove the cylinder, 2x tanks and replace it with an pressurised cylinder and filling loop along with new radiators. They chose to keep the...
