Replacing RF600 with hive

[RandomGrinch]

Do you get either? Didn’t you take a before photo of the wiring for the previous programmer?

I was hoping that...

I have replaced the old programmer with the new receiver using same wiring ports.

no wiring was changed from old programmer,

Meant that the old programmer used the same backplate, not an unrealistic assumption, but we never know!

I believe I is to the programmer, B is to the boiler, and there is a black wire from the boiler, that connects with a white cable (to the right of the 3 port valve cable), that goes to a pump?
The cable that is next to the WR1 cable, I believe has wires to the tank stat.

Yes it does

Ok, so it probably isn't to do with the wiring we have just changed.

Next I would keep our wiring change, take the WR1 off it's backplate (be careful of the live contacts) and put the old programmer back and see if that still works.

Does that make sense?

Sorry, don't have the original programmer now it got damaged

 

[RandomGrinch]

Yes it does

Thanks, I'm confident I've got the wiring sorted (in my head at least!).

It's probably unrelated, but the only niggle I have comes back to...

Just to note, there is a green/yellow wire connected to HW On, on the Hive backplate - I can't see any green/yellow switched live wires in the wiring centre. Was any wiring changed from the old programmer, or is there another junction somewhere?

The green/yellow wire at the programmer (somewhere) changes into a white wire at the wiring centre, going into terminal 1.
Did you touch the backplate of the original programmer at all?

The backplate is now the new hive plate as the original was larger, wires where though put back to corresponding terminals

Then no sign of a white wire?
There must be a junction elsewhere.
What was the model of the old programmer?

I can have a look in the morning for any junction.

I cannot be 100% on the model number but think the original programmer was a Drayton, possibly lp722

As I say it's only a niggle.
The LP722 is a direct swap for the Hive dual channel (you have got dual channel?! ). So things should be working.

Sorry to bombard you with questions, but did you try..

did you use the buttons on the front of the receiver to try and turn the heating, or water on?

Or did you try controlling it from the Hive thermostat.

I’m with @RandomGrinch - it’s either the green/yellow wire used incorrectly, wired up incorrectly or perhaps a faulty Hive. Do you have any electrical testing equipment?

 

[RandomGrinch]

or perhaps a faulty Hive

If receiver button presses don't do anything, I think I'd try linking out the programmer backplate next, if @Wiggy000 doesn't have any test equipment?

I thought about linking out, but if that is an earth wire could trip electrics? Or would that have happened already?

I was just double checking...
If the green/yellow was connected to earth, then the electrics would have tripped if hot water was selected at any point. If Heating only was selected, then the C/H should operate with no trips.
A link out between L and 4 at the programmer would be a safe test.

Thanks for the comments, and to make things more interesting and confusing. Woke up this morning to find that schedule set on hive has kicked in, so all working, now very confused. A bit later this morning I will re check the buttons on the receiver to see if they fire the boiler.

They only other think I can think of is it has been pretty cold so a frozen condenser pipe on boiler, as I believe that can prevent boiler from firing? Although yesterday was pretty warm and wet so I would of thought that would of thawed.

Thanks for all your help, I will keep you posted
