rewiring a property and told young apprentice rip out all old wirng
unfortunately he included the boiler controls in it
its a worscter 28cdi combi now the stat a manual one was made off in a 6 terminal junction box i know that the stat goes straight to the boiler but this jb also had wires going to a wiring station
the system has 2 zone valves and a hot water cylinder with a stat
i cant work out how they were controlling the zone valves with just a 3 core up from the boiler which is just the stat
any suggestions
