honeywell y plan

[mal-165]

Hi, I am intending upgrading the controls on my heating system, currently there is a Sangamo M8 which gives no control of the DHW. I intend to use a honeywell 3 port mid position valve. honeywell L641A cylinder stat, a honeywell CM 927 wireless programmable room stat and a WickesRWB9 (already have this from a former installation) to control the timing for the DHW. I would appreciate your advise as to how to wire the wickes controller for my situation. I have got lots of good info from the Honeywell website regarding the wiring of their components.
thanking you in anticipation..
