Hi Guys

[Code Breaker]

Hi there, I have following setup:
BG 330+ (Glow worm re-badged)
RC Plus wireless thermostat in hall
Timer/control Model UT2 in cupboard upstairs with hot water tank.

I bought the new Hive 2 kit for 'heating and hot water'. I unclipped the timer/control UT2 and clipped the new dual channel receiver onto the back plate. I setup rest of the Hive gear and its all up and running, except that the it doesn't start and run heating. Hot water works ok. I can access the thermostat from my phone and the internet and despite it saying heating is on (even if I set the temp to maximum) the boiler doesn't fire up.

The central heating light on the receiver lights up when expected but boiler not turning on.

Any ideas where I've possibly gone wrong or overlooked setting?

What I have noticed is that marked as number 4 on the new backplate for the receiver doesn't exist on the back of the UT2? I haven't changed the back plate to new one, old backplate has just been left and new receiver connected over onto it.

Many Thanks in advance

I've put batteries back in to the RC Plus, leaving all the new setup in situ, and when I turn temp up on RC Plus the boiler fires up and central heating kicks in! must be something silly.

I've a feeling its something to do with missing pin on old UT2?

Ya need to wire the back plate accordingly. not all programmers stats etc have the same configuration. Btw i'd recommend a heating engineer to do it who understands what wire does what. Unless ya understand and can test ya may knacker the new gear or get shocked.

Thanks for your reply. I understand your advice, and I expected the back plate will need rewiring, hence I would like the wiring diagram that shows which wires need moving.

I attached pictures of All devices in the existing and new circuit, so surely this can't be that hard.

Many Thanks

Attached is picture of wiring on back plate under the original UT2 as fitted by BG 2.5 years ago. So can anyone tell me which wires need moving to where? I've marked wires of what I can make out?

You don't have enough cores in the existing cable to wire as per the diagram.

We can't really tell you which cable to move without seing the wiring centre itself, and even then I would prefer to trace each cable to be sure which core is used for what. Any advice given on the basis of incomplete knowledge could cause damage to components, or bigger electrical problems.

It shouldn't take a competent hetaing engineer very long at all to figure out your existing wiring configuration and rewire accordingly. You will quite likely need another cable to be run to the backplate though.

For others that are new to this and to conclude, once I took a look at it all, all that was needed, which I'm sure all of you know/knew, was to reconfigure two wires to get the hot water running properly which is what I mainly needed, I will run a new cable from the UT2 backplate to the WR1 downstairs and connect to the two heating ON/OFF wires in the summer to complete.

In the pictures of the back plate, remove link between L and 1, then move wire from 2 to 1 that's it!


Thanks.

Thanks?

Huh? Yes thanks to those who replied.
