C. System Components
1. IPS M720 pH/ORP Controller
a. Allows automatic monitoring of pH and ORP levels through
a simple, user-friendly interface, resulting in easier
management of water balance in swimming pools, spas, or
circulating water environments.
b. Can be easily installed into your existing pool environment
and equipment, or can be customized to your needs.
c. Monitors and displays the pH and ORP levels using LEDs
and digital readouts on the front panel.
In addition, five separate function buttons allow simple
pushbutton control of these individual parameters:
1) Mode - Auto or pH Standby (programming),
2) Set Level - pH level to be maintained,
3) Dose Timer - Timed or Continuous feed modes,
4) Delay Time - Delay period after each Dose Time,
5) pH Cal - pH calibration.
d. When the pH level rises above (acid feed) or falls below
(base feed) the set level, the controller will activate the
chemical feeder for the set dose time. Then the set delay
time will occur. This dose and delay time will occur until
the set level is reached.
e. When the ORP (sanitizer) level reaches the set level, the
controller will activate the chemical feeder for the set dose
time. Then the set delay time will occur. This dose and
delay time will occur until the set level is reached.
2. Flow Cell with Flow Switch
a. An injection-molded flow cell with integrated flow-switch
houses the pH and ORP sensors, and partners with the
M720 controller to monitor the pH and ORP levels in the
water.
