Hive - Potterton EP3000 - help

[stevens1975]

Hi guys.

I have a Potterton EP3000 remote controller and a Worcester Greenstar Camray Utility 25/32

I've upgraded to Hive but I've got a problem. I can fire the hotwater up and the boiler kicks in, however, when I try to fire up the CH, the hive registers that the central heating is on but the boiler doesn't fire up.

I've attached the following pictures
1) Old Potterton wiring
2) Hive wiring
3) wiring in box by boiler.
4) wiring box cover

Any ideas on what I've done wrong please

That's great

Do you have two port valves or a 3 port

 

[stevens1975]

Its a two port.

attached is a photo of the set up in the airing cupboard if this helps.

When you link 4 and 5 on the old programer does the boiler fire for ch (you might need to turn the room stat up )?

The wiring is how it was on the original programmer and we've never had a room thermostat before. When you up the temp on the hive it show the central heating to be on but the boiler doesn't fire up

Link 4 and 5 on the old prog boiler should fire on ch

The old programmer has been removed and everything worked fine before.

Are you asking me to put the old programmer back on and change the wires?
