On a y plan system using a megaflow don't you have to wire a second shut off valve ( standard single port valve) to protect it incase the 2 port fails and calls for heat constantly

Yes chopper76 I believe this is new practice hence why people are moving away from 3 port valves and fitting 2 2 port valves instead easier for the installer all round. Normally you get electrical drawings with the cylinder too.
