Step 7CS
Selecting the use of an outside signal to initiate a regeneration:
Selection only matters if a connection is made to the two pin
connector labeled DP SWITCH located on the printed circuit
board. Following is an explanation of the options:
oFF - Feature not used.
NOTE: In a twin alternating system each control must
have a separate dP signal or dP switch. One dP
signal or one dP switch cannot be used for both
controls.
on0 – If the dP switch is closed for an accumulative time of
2 minutes a regeneration will be signaled to the unit.
In a twin alternating system the MAV will transition
first to switch units so that the signaled unit can start
regeneration. After the MAV has fully transitioned, the
regeneration begins immediately.
NOTE: For W100T-CWS200 control valves
programmed for twin alternating: if the dP
function “on0” is set, the Delayed Rinse
and Fill feature is not available.
dELy – If the dP switch is closed for an accumulative time of
2 minutes a regeneration will occur at the scheduled
delayed regeneration time. In a twin alternating system
once the dP switch is triggered the PC Board will
display “REGEN TODAY” and when the delayed regen
time comes the control will switch tanks and the
triggered unit will then go into regeneration.
NOTE: For W100T-CWS200 control valves
programmed for twin alternating: if the dP
function “dEL” is set, the Delayed Rinse
and Fill feature is not available.
HoLd – If the dP switch is closed a regeneration will be
prevented from occurring while there is switch closure.
In a twin alternating system the regeneration of a
unit can be prevented upon switch closure. If the
unit depletes the capacity down to zero, it will not be
allowed to switch tanks to regenerate until the switch
is open.
NOTE: For W100T-CWS200 control valves
programmed for twin alternating the
Delayed Rinse and Fill feature can be set
in conjunction with the “HoLd” if desired.
