Y plan wiring system

[feebs73]

Help, I have a y plan wiring system I need to change, I have a Drayton wiring system, stat, cylinder stat, wiring loom, time clock, and the plumber has installed a Honeywell valve, is the wiring in the Honeywell valve the same as a Drayton valve i.e. same colors?, regarding the links in the wiring loom do I install all the dotted lines as it says or is a Y plan different.
Many Thanks to anyone who can help

The mid pos valve will work with whatever wiring accessories you have. Colours are universal - orange, white, grey, blue & g+y.

The easiest way is as you have said, to follow the connection diagram on the inside lid of the wiring center.

There are a number of wiring diagrams for further info in the 'stickies' at the top of the forum.
