MX III CONTROLLER OPERATION
CONTROLLER OPERATION DURING PROGRAMMING
The controller enters the Program Mode in standby or service mode as long as it is not in regeneration. While in the
Program Mode the controller continues to operate normally monitoring water usage. The controller”s programming is
stored in memory permanently.
CONTROLLER OPERATION DURING A POWER FAILURE
All program settings are stored in permanent memory. Current valve position, cycle step time elapsed, and time of
day are stored during a power failure, and will be restored upon power re-application. Time is kept during a power
failure, and time of day is adjusted upon power up (as long as power is restored within 12 hours).
NOTE:
A flashing Time of Day display indicates a power outage. The flashing of the time of day can be stopped by
pressing any button on the display.
REMOTE LOCKOUT
The controller does not allow the unit/system to go into Regeneration until the Regeneration Lockout Input signal to
the unit is cleared. This requires a contact closure to activate the unit. The recommended gauge wire is 20 with a
maximum length of 500 feet. See P4 remote inputs in the wiring diagrams in the service manual.
REGENERATION DAY OVERRIDE FEATURE
If the Day Override option is turned on and the valve reaches the set Regeneration Day Override value, the
Regeneration Cycle starts if no other unit is in Regeneration. If other units are in regeneration, it is added to a
regeneration queue. This occurs regardless of the remaining volume available.
