Drayton LP522 to Drayton Wiser kit 1

[scotlad85]

Hello All above photo is the setup from the old LP522 which allows heating on and off and water on demand when I use the tap. When I have connected the new Wiser panel. The hot water will work on demand but the heating doesn't. Assuming it needs adjusting. Does anyone know the configuration? Apologies I got no Manual with it

Boiler is a Worchester Greenstar 32CDI

Yellow / blue in T3 and 4 on old backplate move to T1 and 2 on the wiser backplate.
You may already have done that, though.

Live also needs linking to T1 (the 522 did that bit internally).

EDIT wrong wiring see later corrected post

Is this a combi, hence the Wiser Kit 1? Do you have a hot water cylinder?

No just a combi without a tank

Can you post a photo of the Wiser wiring? Have you done anything that @Rodders53 has suggested?

Thats what I dont have? I dont have the wiring document. The backplate for the drayton wiser panel is the same as the LP522

Ok, so you need the link from L to 4

I know, same manufacturer.

It might be physically but not wiring wise.

NB I was wrong wiring wise

L loops to T1
Yellows stays on T3 CH on/call for heat
Blue needs to move to T4 as it was HW call and is unused in the Wiser 1. T4 is not connected and a parking terminal on Wiser 1.

EDIT. You'd be wise to check and double-check I
I have finally got that wiring right.

This configuration doesnt work. Heating doesnt come on

You have put Blue needs to move to T4. Its already on T4.... as per your instructions its simply loop L to T1. Going by what I already had. Do you mean Blue goes to T1?

Apologies I got it wrong (a little tired today). Link L to 1 and blue should be terminal 3 (Normally Open). Yellow shouldn’t be required as it’s previously for hot water. Any existing thermostat needs to be bridged or set to maximum.
