Smart pH 4
1.4 SMART PHTM OVERVIEW
SUMMARY: The Smart pH is a microprocessor based, modular automation system capable of
continuous local monitoring and control of the pH water chemistry for pool and spa
applications. The Smart pH will maintain the pH levels (either increasing pH using base
or decreasing pH using acid) of your water system automatically. The Smart pH will
only increase or decrease the pH. The Smart pH is recommended for use with a
chlorine generator or an erosion type feeder. You can also use the Smart pH when hand
feeding liquid chlorine (base) or muratic acid as the chlorine will increase the pH and
the acid will decrease the pH. The Smart pH can also control CO2 gas systems with the
same efficiency as an acid feed controller. (For specific information on installation refer
to documentation supplied with CO2 chemical feeder).
RELAY: The Smart pH has one relay module to control the pH levels.
SENSORS: The Smart pH can measure inputs from one pH sensor.
VOLTAGE: The Smart pH can only work on an input voltage of 110 VAC.
