Hi all, first post and it's a good one, so after some research I decided upon getting the vallient 938 boiler as this website said it was compatible with opentherm https://uk.myboiler.com/opentherm-capable-boilers/ via the vr 33 module I took the plunge.
As it turns out after scouring the Internet for a wiring diagram for the vr33 module it looks like the x31 socket on the 938 is being used. However there is a x31 port on the vr 33 so I'm wondering if this would just daisy chain?
Any help would be great.
