so I've got an s plan heating system in 3 story house, separate valve and stat for each floor, then the hot water valve and then another valve for underfloor heating in extension. altogether 5 valves. so this wont work on standard 10 way honeywell junction box right? I'm learning these systems and want to understand them better, please talk me through it a bit and if possible direct me to suitable wiring diagram that would be close to this, i'm looking at the standard s plan, im thinking you would need larger junction box to have each stat operating each valve seperatly?
