Hi,
Please can I get some help with a hive install. I have multizone heating, so I have a Hive dual channel receiver and a single channel receiver. This has been installed since 2017 and working without issue. I have a hot water tank upstairs with ZA5 valves for the upstairs and downstairs central heating.
I haven’t used the central heating since the start of summer, fired it up the other day and the downstairs radiators aren’t working. To clarify, the hot water and upstairs radiators do work. The downstairs radiators use the dual channel receiver.
I assumed it was the motorised valve, but I have changed that and it didn’t solve it. More investigation and I’m pretty sure the downstairs heat On is not getting getting any power. The hive receiver turns green, I can hear the relay in the receiver click, but nothing happens and I don’t ‘think’ I get voltage on the switch wire near to the valve.
I should say, I have builders in at the moment, wish I had tested this before they started working!
Please can someone confirm that I have this right. In the picture of the hive receiver wiring, number 4 is the heating on and in the second picture, marked green is what I’m sure is the switch wire.
When a call for heating is made, mains voltage should go to number 4 and to the valve. If I get no power to the valve, then I think that either the builders have damaged the physical cable.. yet the permanent live has power.. or the hive receiver isn’t actually switching on number 4 although it looks and sounds like it is.
How can I test the continuity of the cable, could I bridge the permanent live to the switch and make sure the valve operates.. or how can I test the hive receiver? Or am I missing something else.
Thanks,
Chris
