Mate of mine has been let down by some sparks doing some work at his house and they were supposed to redo his heating side (s plan).
However this has not happened so been their today trying to sort it , one thing thats throwing me is his room stat receiver has 4 wires brown/blue/black/grey yet on the honeywell wiring centre we have terminals 1,2,3 and earth any idea which goes where?

blue neutral
black live sent
grey live return

It will depend weather the programmer is feeding the stat or the stat feeding the programmer but normally c/h on will liven up black. Brown and blue are permanents and grey switch live to zonevalve open however depending on the zone valve it may be moter open moter close if its not spring return.
