Ok thanks, that was really useful, checked pump when hive was supposedly running central heating, the internal shaft was not rotating. However, i then wired the pump directly to the mains and what do you know the shaft starts spinning. Therefore I guess there might be a problem with how I have...

OK Thanks for the effort! I will take a look at your drawings and have a think. Having checked the remains of the old controller pictured, from which I only removed the wires mentioned above (3 core direct to spur, 3 core direct to boiler (HW on) and 3 core direct to pump (CH on)). I am...

That's what's confusing me, as far as i remember, the wire now coming from the 4 terminal originally ran directly to the water pump, and the wire that was the running from the thermostat ran only to the old controller, at terminal 5 with nothing from the stat connecting directly to the pump. I...

Ah, my understanding of the Hive system was that when the wireless thermostat decided it was too cold, it would tell the controller/receiver to close the circuit running from terminal 4 of the new backplate to the pump, i.e. the physical wire between the wall thermostat and the controller had...

Besides the 3 core going to the old wall stat (now entirely removed) and the 3 wires mentioned, all other wiring shown in that photo was purely internal within the old controller, running between one terminal or another. I assumed the function of these wires was replicated by the hive controller...

Here's my current status...Hive is wired in as described above and with the Hive set to gravity fed system. Hot water fires up fine independently and when CH is scheduled it fires on both the hot water light and the CH. However, upstairs radiators are the only ones getting hot. My thinking is...

Yes as per the original wiring shown above there were two wires going into CH on. Thanks for you help, much appreciated, just to clarify, by the wiring centre you mean the main fuse box for the entire house? Doesn't the hive receiver just connect to the mains via the live connection at the...

Hi all, Purchased a hive and as i have an oil fired Benson Jetstream boiler, BG will not install. Here's what the wiring of the old back plate looked like. What it boils down to is: Wire 1 containing: (1L) - A brown live wire coming from a fused spur, currently connected to the L. (1N) - A...
