Mend Boss CZV222 Valve Heating Cylinder

How to connect a motorised valve ?

I want to connect a motorised valve which would control via a simple on/off switch the heating of my hot water cylinder. I have already installed the valve (a Boss Therm czv222 5wire ) in the circs to the cylinder but don,t know how to wire it to the switch. The wires are coloured brown,orange,blue,grey and earth.
can anybody help?

you got the wrong valve mate u need a 3 wire not a 5 wire
blue = neutral
yell/green = earth
grey = permanent live
orange = power 2 pump and boiler
brown = switch live
more 2 the point mate u cant control the temp of ur water cylinder by doin that

If you just want to control it via a simple on off switch then you have got the wrong valve, you need a 3 way valve with only 3 wires, honeywell v4044c will do the job
