Can anyone pls tell me where these PH controllers are made because mine is "Made in Romania" and i cant find on the net the homepage of the manufacturer.
The only thing I found is the australian homepage.
I have the SMS122 "reverse" controller and I solved all the compatibility issues (plugs and sockets,12V adaptors etc).
My problem is that i want to use a normally closed solenoid valve but this controller (reverse type) activates the solenoid when the ph value goes below the desired set point (the contrary from what i need).
Is there a way to make a modification or some regulation inside the unit so that it can work as the normal SM122 ??
