I tried to wire this in but I still can't get it working.
I connected the L and N on the 927 to the RT 230V on block X1.
I connected the A and B from the 927 to the BUS connection on block X100.
I removed the link on the RT 24V from the X100.
It did not work and the boiler would not fire up...
Hi,
I could really do with some help, I am trying to wire a honeywell CMT927 to a vaillant ecotec plus 832 and the manual is unclear.
I need to know where the L and N and the A and B on the receiver connect to the boiler.
Can someone help, any help is appreciated.
Thanks
Terry
