Our house has two zones for CH and for HW, with 2x Drayton

Customer Question

Our house has two zones for CH and for HW, with 2x Drayton LP722 programmers. Unfortunately they are wired with programmer 1 controlling CH for zones 1&2, and programmer 2 controlling HW for Zones 1&2. I would like to change it so that programmer 1 controls CH and HW for zone 1, and prog. 2 controls Zone2. I thought I could just swap the wire attached to CH Z2 on prog. 2 for the HW Z1 on prig. 1, but that doesn't seem to work. I suspect it is something to do with the motorised valves for the zones, but there is no wiring diagram!

Hi just reading through your description.

Plumberpro :

Are your programmers and wiring centre right next to each other?

JACUSTOMER-80bkzd0d- :

I've never seen a "wiring centre". No idea what that is!

JACUSTOMER-80bkzd0d- :

Bit baffled. My email says I was sent an answer at 16:21 (and that it took the system till 16:21 to verify my payment - over 1 hour!!

JACUSTOMER-80bkzd0d- :

Although it said someone is online, now it says "offline".
