I have a Worcester Bosch Greenstar R29-40 HE Conventional boiler supplying 8 zones and DHW, all pressurised. I wish to control the 9 zone valves by 8 BDR91s and 1 ATF500DHW, these in turn programmed by an ATC928 / DTS92 combination i the heated spaces.

I read from the installation instructions for the BDR91s that they should be 300mm apart and remote from the boiler. Is this critical, and if so how far away could they be mounted for the tails to go back to the valves?
