Hive help - what do I do with original programmer

[real_vibes]

Hello all

First post!

I’m trying to fit a Hive Heating and Hot Water unit in my home.

The backplate of my original Drayton unit is the same size and fits the hive.

I turned the programmer to OFF and OFF (heating and hot water) and merely switched the wireless units around and it did effectively work (tested with hot water and did as expected). However the heating remained on when it should not have been.

I am wondering if I need to remove the old programmer entirely. I’m sure my set up is pretty standard, and yet I can’t find any threads or info on how to proceed.

Pics of the set up below. Any advice would be gratefully received.

White wire with brown sleeve on Hive seems to be wrong to me, would expect to see two wires, two spaces, two wires.

However the programmer needs removing no point having two devices doing the same job. There is some times a case for fitting multi wall thermostats in parallel so if any room needs heat boiler runs, but with Hive the Hive TRV heads do that anyway, so not required.

And is t simply a matter of removing the wires from the old programmer? Or is there then briging etc to be done?

thanks

I can't see enough to be sure what needs doing however it is likely you are using an S-Plan, I can see the two motorised valve cables, and the colours to motorised valves are reasonable standard.

So looking at this diagram the Hive replaces the "Time Controller" however the CH would go to 5 instead of 4 and the wall thermostat is removed. Clearly yours is not using same numbers, so you need to identify which is 5 and 6 on your wiring unit.

So you have 6 cables as far as I can see, 4 you can easy identify, two to motorised valves, one to time controller/programmer, one to new Hive, which leaves two to work out, but looking are four items to be connected, live supply, connection to boiler, connection to tank thermostat, connection to room thermostat. Left hand cable seems to have more than 3 cores, so likely goes to more than one item, possibly supply and boiler?

But from pictures I can't see the links so could not possibly work out what goes to what.
