M920 & M920W pH/Dual ORP Controller Owner’s Manual
C. System Components
1. IPS M920 pH/Dual ORP Controller
a. Allows automac monitoring of water sanizaon and pH
balance through a simple, user-friendly interface, resulng in
easier management of water balance in swimming pools, spas,
or circulang water environments.
b. Can be easily installed into your exisng 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 M920 will monitor temperature and display on the
front panel when in Temp mode. Addionally. 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 funcon buons that allow simple
pushbuon control of these individual parameters:
1. Set Level – ORP or pH level to be maintained,
2. Dose Time – Timed or connuous 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 calibraon for variaon in pH sensors.
d. When the pH level rises above (acid feed) or falls below (base
feed) the set level, the controller will acvate the chemical
feeder for the set dose me. Then the set delay me will occur.
This dose and delay me will occur unl the set level is reached.
e. When the ORP (sanizer) level reaches the set level, the
controller will acvate the chemical feeder for the set dose me.
Then the set delay me will occur. This dose and delay me will
occur unl the set level is reached.
