Key Features
The Commander III Model JC7 display will show the
SANITIZER OUTPUT LEVEL
(in percent %) and whether the system
is in
BOOST
or
SUPER-BOOST Mode
on the first line of the two line alphanumeric display. The second line will display
the current
TIME
in either 12 or 24-hr mode, the
TEMPERATURE
in either Fahrenheit or Celsius, whether the cell is
powered or not, shown as ON or OFF and
Polarity Direction
, shown as a “
.
” or blank. Easy touch pads allow for adjusting
and programming the unit. A
Check System
visual alarm indicator works in conjunction with the display to advise of any
problems. All Menu, Select and Pump functions as well as any “Error messages” will be displayed on both lines of the
alphanumeric display.

The
SANITIZING OUTPUT LEVEL
is adjustable from 0% (OFF) to 100 % (MAX) by pressing the
Up/Down
Arrows to
obtain the desired Sanitizer Output Level. Little adjustment is needed once the initial setting is established.
Note: The Commander III Model JC7 does not test for sanitizer levels nor automatically adjust to maintain a desired
sanitizer level. This is done by periodically testing the water and adjusting the output levels up or down, as needed.
The Commander III Model JC7 is designed with an
AUTOMATIC TEMPERATURE COMPENSATION feature
, which
automatically adjusts the output level setting based upon changes in seasonal water temperatures only. This unique feature
conveniently compensates for warm (more sanitizer needed) or cold (less sanitizer needed) water conditions.
The
BOOST Button
increases the sanitizer output level to 100% for up to 72 hours, regardless of the initial output level
setting. The sanitizing agent is produced, continually; throughout the normal On/Off cycles of the pump and throughout all
power line disturbances until the end of the cycle or when manually discontinued. When Boost is activated with
External
Timer
setting programmed, the time remaining for the boost cycle is held in memory and will start up in Boost mode until
expired. With
Pump Program
or
2-Speed Pump
setting programmed, the time clock will be over ridden, producing
sanitizer until the end of the boost cycle. The display will indicate the
BOOST
Mode
on the second line when the boost
Button is pressed once. Once activated, the system will produce the sanitizing agent for 24 hours. The sanitizing agent can be
produced for 72 hours by pressing and holding down the Boost Button for 5-seconds from the Boost-Off position. This is
called the
SUPERBOOST
Mode
. The display will indicate that the system has successfully entered the Super Boost mode.
To discontinue operation of Boost mode or Super Boost mode, pressed the Boost Button once more. The pool/spa pump must
be turned on during the whole boost cycle. Do not let the pump run on a timer during that period.
The
Menu
and
Select Buttons
allows you to view the TEST mode, program the functions and time clocks. See the following
pages for description of the menu tree.
* The
PUMP Button
allows you to over ride the pump timer to temporarily turn the pump on or off (depending on its status of
operation), or to manually turn the pump off, indicated by the display “OFF FOR MAINTENANCE”. In “OFF FOR
MAINTENANCE” mode, the pump is prevented from restarting by the time clock and is only reactivated only by manually
programming it to turn the pump back on. Not applicable with “EXTERNAL TIMER” selection.
The
CHECK SYSTEM
light will flash if there is a problem with the system. The nature of the problem will be indicated by
the display through various error messages. See the Troubleshooting section, page 14, for repair solution.
FREEZE PROTECTION
:
this protective feature allows the pump, when programmed for One-Speed Pump, to override the
program cycle and run continually (30-minute minimum) when the water temperature falls below 4.4°C (40
°
F). This prevents
any damage to the PVC due to water expanding as it freezes.
