Hive to Worcester Green-Star 24Ri Issue

[Bayley Beard]

Evening All,

I'm looking for a bit of help wiring my receiver for hive heating at home.

The hot water and heating is a system setup with a hot water storage tank upstairs in a cupboard and a boiler downstairs, the hot water tank = BoilerMate OV A-Class.

I have called a friend heating engineer who said Hive isn't compatible with my BoilerMate and to just get the heating only version of the hive heating system instead and only control the heating not the water (he could be wrong) ...

Manuals;

http://www.gledhill-spares.net/documents/BMAClassOV-Iss8.pdf

I don't have a current receiver on the wall in the house anywhere to just change over to the hive receiver, all I have is a powered thermostat on the wall in the hallway downstairs.

Questions;

• Which hive heating setup do I need? Central Heating only or with hot water?

• Do I wire it directly into the boiler or the hot water tank?

• Does anyone have a detailed wiring diagram I could use to try and install it myself?

Thanks in advance, if all else fails I get a heating engineer in to have a look but I thought I'd try my luck on here.

Cheers,

Matt.

You can use a dual channel Hive, it is wired into the boilermate.
Look on page 25 of the instructions that you have a link to, it shows you how to wire it up there.
You would also need to disconnect the existing room stat and link L2 and SL-R where you disconnected it in the boilermate.

So terminate the wires from the thermostat on the wall in connector blocks? and then disconnect the wiring link in the Boiler Mate which goes from L2 to SL-R?

I have put a wiring diagram together for the receiver, does this look right?

CH OFF and HW OFF are not used

CH OFF and HW OFF are not used

Is this correct?

I can't seem to see any connection between L2 and SL-R, I've taken a photo;

 

[ianmcd]

yes your wiring is correct, you do have wires between L2 and SLR, you need to remove these two wires and make the link I have shown

Thanks Ian, what do I do with the wires once I have removed them? Just terminate them in connector blocks?

If you want they are not connected to anything any more you can remove them completely if you want, I would terminate them outside the Gledhill where ever is convenient

Hi Ian,

I just want to double check that i'm ok to completely remove the below cable as that is the cable that feeds the downstairs wall thermostat which will be redundant?

 

[ianmcd]

Yes but as already said you need to replace those wires with the link I posted for you, or it wont work

 

[Bayley Beard]

Thanks mate - all installed and working, I removed that cable and created a link between the two, couldn't of done it without your guidance!

No problem happy to be of assistance

Sorry to hijack this thread, looking to do the same with mine. Bookmarked this thread a while back with the intent to do before my gas fix finishes as I'd like to use hive to control hot water demand as leaving the boilermate to it uses a lot more gas.

Ive had my 2 channel hive for a few years now but just connected to SL‐R so only doing the heating at the moment.


Looks like my boilermate a class is a slightly earlier revision but apart from slightly different layout of the rails, it should all be the same but I'm confused slightly with the presence of existing wires to sl-w and sl-h, following them they look to goto the the rocker switches on the control panel.

Should I disconnected these and just fit the hive as above.

Picture for context.

Thanks in advance for any pointers.

Finally managed to come back to this and trace it on the wiring diagram. The SL-W and SL-H connections are from the rocker switches via the clock. Having looked at the OPs pictures, his has the same connection too, just didn't spot it originally but his terminals are doubled up at the top and that's where they are connected.

So, the logical thing to do in my mind is simply to disconnected them as control will be from Hive, leaving them in place just means the switches need to be in the off position to allow hive to control it?
