& M920W

C. System Components
1. IPS M920
CA
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 M920
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 that allow simple
pushbutton control of these individual parameters:
1. Set Level – ORP or pH level to be maintained,
2. Dose Timer – Timed or continuous feed modes,
3. Delay Timer – 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.
8. FAC Cal – Free Available Chlorine Calibration
9. CYA Cal – Cyanuric Acid Calibration/Entry
d. Displays the calculated Free Available Chlorine (FAC) in parts per
million (PPM) when connected to the IPS Controllers monitoring
website. The ORP / FAC display will alternate between the
current ORP and the last calculated FAC. FAC (PPM) calculation is
not certified to NSF 50.
e. 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.
