All,
I've got myself into a pit of a pickle and after a bit of assistance.
Bit of a background, I've recently moved into a grade 2 listed Georgian priority with a number of foibles, but that is a story for another day.
The heating and hot water are via a boiler (old Ideal Mexico 2) and a hot water cylinder, with a pump and diverted valve, controlled via a Potterton EP2000 system, which seemed to have a mind of its own, hence the reason for looking to upgrading the system. There is no thermostat and no control for the hot water tank apart from a manual immersion heater switch.
I've bought a 2 channel hive system on the premise of the heating and hot water being separate, and removed the faceplate to be presented with an "interesting" array of wires connected in a strange way.
In the picture, the wire coming from below is the fused power, easy enough with live, earth and neutral.
My understanding, when I track back the cable on the left, is that this leads to the boiler and the one from the right goes to the pump and diverted valve.
But going on wiring diagram on the potterton backplate, this would be wrong.
On my understanding, E, N & L are self explanatory, 1 is HW off, 2 is CH off, 3 is HW on and 4 is CH on.
Looking at my wiring, HW and CH off are both not wired up, HW on goes to the boiler and CH on goes to the pump and diverter valve - have I read this right?
So when installing the Hive, would there be a way to off the CH and HW then the thermostat reads the right temperature or would it just be a lack on "on" from each of them?
Any help much appreciated.
