its a 2 port valve
there is two outputs

1. turns on boiler and cir pump

2. opens valve to rads

i will take the valve out of programmer and leave it open. that leaves 1 output CH. winters coming so the raditors will always be on. i will have to get a spark next year

thanks for your help

Or just set the programmer to "10" (or gravity, or whatever they call it) mode and the system will work.

Or just make sure all your heating times also have the HW programmed on.
