Hive setup on glow worm 30C

[alexwilliamrevell]

We have a glow worm 30c boiler in our new house.


Just trying to add our Hive from our old house to this one.


I'm a fire alarm tech for a living so would say I'm fairly competent wiring it in myself. I'm however having trouble getting it to work! Followed the wiring diagram from the manual and I'm getting stuck.


I've wired the HIVE receiver;


Hive Live to the boiler Live


Hive Neutral to boiler neutral


Put a link between Live and terminal 1 on the hive receiver


Then cabled from terminal 3 to the RT terminal.


Removed the link between the 24v and RT on the other side of the PCB. Removed my old remote thermostat from the Bus connections.


When I fire up the thermo stat I can hear the relay click over and the green light comes on, on the receiver telling me it's firing. It's just not activating the heating on the boiler.


Any help appreciated, I don't want to admit defeat

Were there any other switches for the heating on the previous, eg a timer? It could also still be looking for the ebus, I had something once on a Vaillant that needed a factory reset as it wouldn’t go higher than 50 degrees which was set by the previous thermostat and wouldn’t clear.

I don't believe so, I can't remember now. That's a good shout though. Any idea how I would go about that? Or Do you know if Hive or Glow worm will talk to me about it? If I have similar issues with my work I would call the manufacturer.

I'm not sure Hive will have much of a clue and Glow worm may not talk to you, it depends if the boiler cover forms part of the combustion circuit, if it does they won't and you should have it checked for safety. Daft question, but did you use the correct RT terminal?

 

[alexwilliamrevell]

I used the RT terminal that's on the same block as the mains incoming.

 

[alexwilliamrevell]

I see the RT and 24v terminals on the other side had a link in, which I removed. I however believe that's for 24v so I'm not sure that would work with the mains input from the hive receiver

That would seem to be correct:

However, isn't there a clock and internal timer which would have to be set to permanently on?

 

[alexwilliamrevell]

Im not so sure sorry, how would I go about looking for that? Or checking that out?
Thanks

Is this the correct model?

If so:

 

[alexwilliamrevell]

Oh right, no doesn't look like that. Just the menu button with a + - with the pressure displayed on the LCD screen. I wasn't sure if there was maybe an internal clock you was talking about sorry

 

[EFLImpudence]

Ok, which model is yours, then?

You must have a timer somewhere. Is that set to ON.

 

[alexwilliamrevell]

It's the energy 30c

Ok, this one:

Ok, so I've got it working. After playing around with it. I used the RT and 24v terminals on the right hand side of the PCB. I noticed that these needed a NO/ COMMON going closed connection to start the heating. So played around with the hive receiver and noticed I could get this with no voltage directly from terminals 1 and 3 with no links installed. When I fire the thermostat the relay would kick in and give me a common/NC, going directly into the 24v and RT.

I got there in the end .

Thanks for all the help

I think.
