One thing I just picked up on. Tom said the zone valves can be fitted at start or end (or even middle?) of a zone? Wouldn't it be preferable to plumb them in at the start to avoid possible pressure loss or does it really not make much difference? I've got the ck strippers but if I was buying again I reckon glowbugs recommendation of the £12 ones would be the ones to go for - they certainly look very similar to the ck. As for those Silverlines - haha made me laugh. For 4 quid surely worth doing a "review" of them for the comedy value.....  |

Wiring wise, zone control is easy too Rocky.
John’s videos are great & really worth watching.
However, the basics are; all the Neutrals & Earths are ‘common’, they’re just bunched together & forgotten about. For simple On/Off central heating controls its only the Live that’s switched, and it’s dead simple too.
In electrics there’s two main types of circuit, in series & in parallel. Check that out on utube, plenty of good videos on there about that subject, in fact John will have one👍👍
OK, for zone control it’s all Live serial switching(switch lives); the timeswitch/programmer makes/switches when it’s time for heat - the power goes to a room thermosat & if it’s below the set temperature it makes/switches - the power goes to the zone valve & it swings open.
Now, there’s a permanent live going to the zone valve & it’s connected to a wee micro switch, when the valve swings open it makes/switches the micro switch, so the permanent live power then runs the circulation pump & fires up the boiler.
All very simple as you’ll see on John’s video of an S Plan.

Dick/Rocky - I really like the Y and S Plan diagrams on the Octave Blue website by someone called John Turnball. The diagrams highlight the wires used for each function of the system by flashing to show the path of the live from programmer, through the wiring centre, to the boiler and pump. Makes something that's sometimes difficult to grasp, especially Y Plan, easy to follow.

They’re very good Woody, I see John is a Christian. I wonder what he says when he hits his thumb with a hammer?? |
