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

What does blue tend to be used for? :wink5:

on a plug it would be neutral but i did put it in the N on the terminal block and it didnt work i aint no sparky lol

will it make a difference white/brown not white black as the one in the picture is white brown ? what i carnt get my head round is the hot water works fine on the programmer ? even if the blue wire is neutral hot water still works ? its just the heating wont switch on from the programmer ?

 

[MZR]

im thinking the brown and white is wrong ? and neutral is just left out ?

There a duplicate thread going about

what type of valve is it (mid, diverter) ? and tbh mate it might be easier to change the valve for a new one depending on age

Why are the earth wires going to the grey wire on the zone valve? I think this needs to be stripped out and redone properly

did it work after my thoughts no

 

[ShaunCorbs]

mid position standard

blue netural
brown and white heating call
orange hot water call
grey hot water satisfied

i am crap with the wires on the terminal blocks just looks like a birds nest, what am i looking for to add the brown and white too ? would it go to the programmer ? sorry for the lame questions or where should it be going ?

 

[ShaunCorbs]

black wire

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

 

[MZR]

cracking guys thanks

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 ?
