Try setting up today morning.
After some help from Bro Alex,finally setup the unit.

The controller was plastic seal and it come with a standard 3 pins plug and 3 pins control outlet.

PH/ORP controller
 

Are you using it for ozone generator? use only the ORP controller part?

The set come with 2 probes.One for PH and one for ORP
Both probes are also seal with plastics.
Below is thepicture ofone of the probes.

After removing the plastics seal from the probe you have to remove the front protection cap also.
This is the front protection cap you need to remove

After cleaning the probe under tap water.I connect up to the controller.
I select ORP and M.
The initial reading on power up is 154.
This reading continue to drop slowly 1 at a time.
After about 10 min it is reading 131.

Yes,bro.I am using for the ozone generator.
Thank You

Regards

I didnt attached the PH probe, cos it need buffer solution to calibrate (2 somemore, 7.0 & 4.0), anyway I'm only using it to control my ozone generator.

Question: How long it take for the controller to stablise, I got funny reading, everytime I turn on the ozone generator, the reading start droppping (thought its suppose to increase).Clueless??? :confused:

Ariel .. check out this thread as there are discussions regarding how long does the orp probe stabilize.
