Frequently asked questions

What is the maximum input voltage for the Smart pH 3?

The maximum input AC voltage must not exceed 125 V AC.

Can the relay control voltage be changed from the factory setting?

Yes, changing the jumper on the relay allows for different control voltages of 24V or a Dry Contact Switch.

Where should the flow sensor and pH sensor be installed relative to other equipment?

They must be installed after the filter but before the chemical injector, with the flow sensor placed before the pH sensor.
