No probs

I have an EP2002 controller. Just fitted a Hive so its going beggin.

All working fine now. Two new valves fitted. Power to HW one from 5. Power to Heating one from 8. Both Grey switch wires connected to No 3 and Oranges to No 4. Now it allows HW and Heat to operate independently.

OK after industriously working my way through the various connections I have now established the following: The heating motorised valve powers open but the NC/NO connections remain open circuit whichever position its in. The hot water motorised valve doesn't power up and is permanently open and...

No, I meant the live was in 4, yellow in 3 and hot water in 2

Yeah, I'm thinking that's where I went wrong. I left the remaining wire in 5. That would mean the heating on was in the hot water on connection and the hot water on was in the heating off connection. When I get home I'll move the red from 5 to L and shuffle the other two up one. Hopefully...

Lol, yeah, and also not helped by the (I’m going to assume)installer using a bit of 2.5 flex to connect up the heating valve utilising the green/yellow where a white would be. I’m gradually working my way through it and agree, i think the issue is the wiring at the controller. The connections...

Sorry. I meant the heating valve

Ok. Been at this for hours tonight trying to figure out why it’s still not working properly. Managed to get the controller back out of gravity mode and it’s turning on and off ok. When I choose heating only. Pump runs but the heating motorised valve doesn’t open unless I select hot water. Then...

Ahhh. I see. Yes, those are the before pictures.

Yeah, I set it to gravity fed as the system is gravity fed. I’ll try it on fully pumped and see if that changes it. Daft thing is it shows heating and hot water independently on the screen but the receiver always has both lights on when the system is running.

Just wondering. I have the same system and have followed the instructions here but I thought you could have the hot water on but the heating off, but mine seems to run both at the same time. I’ve wired the receiver as shown (removed the live link) and shorted the red and yellow at the...

I'm also looking for a couple of these. did you find a supplier??
