If ROTATION is set to PUMP HRS, ROTATE TIME is used to
switch pumps when the pump‘s time difference is greater than
ROTATE TIME. Whichever pump has the least time and is at least
below the other (pump‘s time - ROTATE TIME) will switch to the
enabled state. This selection is used to equalize run time on the
pumps.
MORE MENUS New menu screen follows.
ZERO RUNTIME PUMP1 PUMP1- PUMP2
This menu allows the clearing of a pump‘s runtime counter.
Discretion is advised in clearing only one pump‘s hours after
replacement and then using ROTATION set to PUMP HRS. This
would cause the pump whose runtime was cleared to run until it‘s
time exceeded the other older pump.
