Hive active heating help

[Bibson]

Hello, I recently purchased the hive acting heating system and was looking for a little help on the wiring, my current programmer is a honeywell st9520c, I will include a wiring diagram of how it is wired into my house and also a diagram of the hive receiver, any help appreciated, thanks

Your present system has two zones, normally they are controlled with two separate thermostats and configured as 'upstairs' and 'downstairs'. The Hive only has a single channel, so is not a suitable replacement.

 

[Bibson]

So would I need to buy the additional multizone kit, or can it be rewired to a "single zone"

 

[stem]

In theory you could do either, but if you did wire it as a single zone, if the room where the upstairs thermostat is presently sited doesn't have a thermostatic radiator valve, it will likely get overheated.

I'm assuming too, that your property is fairly new, so the two zone installation would have been done to comply with the current building regulations.

So, as your system has been designed as a multizone, it would probably be best to keep it that way.

 

[Bibson]

You are correct it is a brand new build, I will purchase the multizone kit, this consists of another thermostat and single channel receiver, could you assist me on how this show be wired

If I'm around I will help, but if I'm not, you will still find quite a few regulars on here who are mustard at this sort of thing.

What boiler have u got?

You appear to have open thermostat connections there.

Hive is not open therm

Yes indeed, good spot!

I saw in the circuit diagram that the motorised valves were wired at 230V from the programmer, and that the grey wires to the motorised valve microswitches normally used for boiler control are shown wired to a permanent live, but then when you follow the orange wires that normally control the boiler they don't actually go anywhere.

It's a vokra linea one combi

@vulcancontinental is this OT?

 

[Bibson]

Yes it is ot compliant

Then you'd be better off ditching the hive and going with a Honeywell lyric or Vokera's own besmart.
I'd await Vulcans advice though cos he knows more about open therm (specifically with Vokera's) than anyone else I know.

Whatever u do don't put any voltage down those 2 wires

May just ditch for nest then, I believe it is opentherm compatible and can be set up for zoned heating, really wanted to have a system that is compatible with the amazon echo as the house is now kitted out with echo automated tech
