C. System Components
1. IPS M820 pH/Dual ORP Controller
a. Allows automac monitoring of water sanizaon and pH
balance through a simple, user-friendly interface, resulng
in easier management of water balance in swimming
pools, spas, or circulang water environments.
b. Can be easily installed into your exisng 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.
Addionally, 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 funcon buons allow simple
pushbuon control of these individual parameters:
1) Set Level – ORP or pH level to be maintained,
2) Dose Time – Timed or connuous feed modes,
3) Delay Time – Delay me between feed cycles,
4) Over Timer – Maximum feed cycles or me 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 calibraon for variaon in pH sensors.
d. When the pH level rises above (acid feed) or falls below
(base feed) the set level, the controller will acvate the
chemical feeder for the set dose me. Then the set delay
me will occur. This dose and delay me will occur unl
the set level is reached.
e. When the ORP (sanizer) level reaches the set level, the
controller will acvate the chemical feeder for the set dose
me. Then the set delay me will occur. This dose and
delay me will occur unl the set level is reached.
