for the next days operation, a regeneration cycle will be initiated immediately or at a preset time.
Time clock:
The controller will regenerate based on a set time of operation days.
Remote regen start
The controller will get a signal from a separate device to start the regeneration.

5.7.2. Multiple valves with lockout (System #5)

This system works with 2 to 4 valves.
All tanks in parallel are supplying treated water. Each unit in the system has its own flow meter. The
controller will delay the start of a regeneration if another unit is already regenerating. Once that unit
has completed a regeneration cycle and returned to service, the unit with longest regeneration queue
time will begin regeneration. Only one unit regenerates at the time.The regen can be trigged on a
volumetric or remote signal.
