Danfoss HSA 3 valve

[MZR]

hi all

been called to a gloworm ultimate 60ff today with a danfoss hsa3 motorised valve, the hot water works fine the heating when called for the stat says its on but the valve is not moving if i put it on manual then it all works fine but the stat wont switch it off until the valve is moved from manual, ive checked the wiring and found this blue wire from the valve not connected i have no idea where it goes and carnt find the pdf online for the valve i have attached a picture any help would be great the blue wire has red tape on it

Blue is a neutral
Brown/white goes in with ch on or return from room stat if there is one
Orange goes in with hw off and sat from stat
Grey goes in with pump boiler and cyl stat call

black wire

if there is no room stat which there is not, the black (br/wh) goes to CH (terminal 4) and the programmer will act as the switch ?
