Hive - Should I need to do HW & CH, or should CH do nothing??

[Chris M]

Hi Fellas, I've had a sniff around the forum and can't find a conclusive answer..

I've had Hive installed a couple of years ago and I'm starting to question if it's wired correctly or if it's just how my system works since I now know a few people who have it installed.

When I call CH, I have to also put on HW separately. Calling HW only does not turn on CH you'd expect. I'm not certain how the system worked pre Hive as we had it installed the week we moved in.

I've tried to read up on fully pumped vs gravity vs part pumped/ Y plan without HW off and the like but I'm no clearer on my set up. Below is a picture of the receiver wiring that shows there are 5 wires, but they're into 3 positions.



At the time the wife told me the installer said he'd had loads of trouble making it work but had got there in the end..

If it helps, the boiler is a greenstar 30CDI

System boiler with hot water cylinder?

We will need to know what type of set up, you have? S plan/Yplan or whatever.

A pic of the cylinder cupboard would be good.

Hi guys, missus has banned me from banging around the kids bedrooms till the morning!

(There a blue pump in there under the floor.

One thing that I couldn't identify is a black plastic box that appears to just sit 'on' a pipe that's got mains power to it with the word Range on it! (Took a pic of that earlier)

I'll kick proper pics in the morning.

Thanks all

Hi all,

Airing cupboard pics attached..
The pipe going in to the roof isn't connected - kind of looks like a sealed system looking at it but I don't know much!

Under the raised floor there are 2 pumps which I photo if needed but need to do a little dismantling - one is older. I've only caught the newer looking one of them running but we do have 3 power showers each with own pump so not a clue if one is 'support'?

I also notice when in the garage (near boiler) that boiler pressure was low (in the red) so assumed I could top up easily but there appears to be no loop and a sticker with 'direct cylinder' written on it!

(And in one of the colder rooms in an extension appears to have a cold outflow pipe despite rad getting hot but one thing at a time!!)

Thanks again.

What did you have before you had the hive fitted and how did it work previously?

Hi, there was just a large time clock there but we whipped it out not long after moving in over 2 years ago so don't remember to be honest :-/

I'm curious as I've never seen a diagram which groups 3 permanent lives (but that's limited to Google in the last week or so :-D).

I'm thinking I'm screwed for unless I pay someone to come and have a look first hand.. I'm comfortable with Electrics generally, but don't want to fry anything in the boiler by guessing!
