CM 927 installation

[cully]

Please advise on the following,
While I am waiting for the plumber to change the boiler I require pointing in the right direction with the CM 900 wireless relay box.
I have powered the relay box L & N to mains and have it responding to the 927 stat heat demand (stat to relay) I have then taken a wire from relay box "B" terminal to a zone valve "brown" for this to operate the zone valve then start the boiler (the rest of the zone valve wires are connected as required apart from orange that will switch the boiler when its fitted
The problem is that I have 240V to the relay (L & N) but no volts at terminal "B" when in heat demand. (checked with volt meter between B and N
I am missing something apart from the voltage
There is no link between L & L in the relay box
All advise appreciated
Paul

Thanks Dan,
Don't ask why I didn't look at the wiring diagram for zone valve control because I don't know what I looked at but obviously not that.
Both zones are now working from the two stats.
Just waiting for the plumber to fit the boiler for my neighbor
Thanks again
Paul
