M820 pH/Dual ORP Controller Owner's Manual
C. System Components
1. IPS M820 pH/Dual ORP Controller
a. Allows automatic monitoring of water sanitization and pH
balance 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. If the temperature
sensor is installed, the M820 will monitor temperature
and display on the front panel when in Temp mode.
Additionally, it will monitor up to two chemical tanks
equipped with level switches and displays status using LEDs
on the front panel.
There are six separate function buttons allow simple
pushbutton control of these individual parameters:
1) Set Level – ORP or pH level to be maintained,
2) Dose Time – Timed or continuous feed modes,
3) Delay Time – Delay time between feed cycles,
4) Over Timer – Maximum feed cycles or time allowed,
5) High Alert – Maximum level of ORP or pH allowed,
6) Low Alert – Minimum level of ORP or pH allowed,
7) pH Cal – pH calibration for variation in pH sensors.
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.
