I bought the Hive Active Heating 2 (Black Friday) but I'm having trouble with the wiring. It seems my 20+ year old system is missing one wire - has 5 connected, but should have 6 wires.
This is the desired dual channel wiring diagram for the new Hive receiver which looks fairly simple if it was a straight swap:
I have a central heating + hot water system:
- Ideal Logic heat only boiler
- Lifestyle LP522 programmer/timer
- Hot water cylinder, pumped/gravity fed system/mid position valve, tank and room thermostat
This is the current wiring:
N - Neutral
L - Live supply (red) + Permanent feed for new boiler (brown)
(Previous boiler was switched by the timer but new one required a new core)
1 - HW/OFF (blue)
2 - **BLANK**
3 - HW/ON (red)
4 - CH/ON (red)
I tried wiring like-for-like on the new Hive receiver but when I tested CH, both CH and HW came on which doesn't look correct. I disconnected and put the old programmer back on to avoid any damage to the system.
Does any one know why my current system doesn't have a CH/OFF connection?
How should I wire this up to the new Hive receiver?
Any suggestions/help would be greatly appreciated.
P.S. I opened the junction box on the wall and nothing's labelled. It would take me some time to work all that out but maybe that's what I need to do - but hoping someone has a quick answer:
