Pick your brain on Honeywell Multiple Heating Zones Wiring

[bashmaystor]

Hello all
I am designing an 4 zone central heating system, which comprises of:
- Vaillant Ecotec Plus 637
Zone 1 - Main Unvented Direct Hot Water Cylinder 300l
Zone 2 - Garage Rads
Zone 3 - House Rads
Zone 4 - UFH manifold (Nu-Heat)

2 Channel Programmer for zones 1, 2.
1 Channel Programmer for zones 3, 4.
I will use Honeywell Programmers and room-stats.

Does anyone know if a ready made wiring diagram exists for multiple zones such as above?

What I figured out is that almost always I have to design the wiring myself and its never like for like with the provided diagrams. I am hoping that there is a simple to follow diagram for multiple zones out there.

Many thanks
Vinnie

You will need a 2 channel programmer for zone 3-4 and room stats so you can have time and tempreture control over the radiator circuit and the underfloor heating you dont want them on together treat it as 2 s plans contact honeywell technical they will advise you , i would work it off a low loss header, cheers kop.

Pretty straight forward. 4 Zoned S plan like Shaun said.

KOP is right to mention the LLH too. I would want to install one of those.
Did you mean 'Indirect'?

If your really really struggling I can sort of whip a wiring diagram up

Hi
Yes Indirect! Thanks for the advice!

Why low loss header please advise

Why low loss header please advise

Any more than 3 zones it's best to fit a llh or where underfloor heating is involved
