ok, I have done more research and as far as I can see the COM port is the common neutral, which needs to go to each solenoid. The other wire on each solenoid then must go to one of the 4 ports in the controller.
I have nothing going into the MV/P port at all, but as far as I can see I shouldn't need to. Why then is the unit complaining about a MV/P Short?
I cant seem to find any reference to why this error occurs, all the manual says is "check the solenoids". I had it wired up with just 1 solenoid (measuring 35ohms) and it still gave the same error.
The only other thing I can see is the 24v output seems to be reporting around 7v, although if I put the voltmeter accross the yellow wires it does indeed report 24v.
Any help would be appreciated, as time is off the essence and I really dont want to fork out for a new unit if it's some rookie mistake causing the error.
Thanks,
Jim
