Unsolvable motorised valve problem
Tado technical don't know how to do this so I'm hoping somebody/anybody here can offer some guidance.
I'm trying to control a normally-closed 5-wire motorised valve (see link below) with a Tado thermostat. I spoke to Tado technical and they said "wire the grey to NO and orange to COM". I did that but as soon a power is applied (blue and brown directly to live and neutral) the valve opens and stays open.
Tado support then said "we don't know, ask somebody else".
Is the valve faulty? Or are the instructions Tado supplied incorrect?
I looked at the wiring diagram here (https://i.imgur.com/VDYqofj.png) and live to the motor seems to go through the room stat and is switched that way, can i put 240v through the Tado stat and turn it on and off that way?
