Modes of Operation
Time Clock
The controller will initiate a regeneration based upon a tim­e schedule of intervals of days (i.e., every 3 days) or
on a specific day of week schedule (i.e., Mondays, Wednesdays and Saturdays). Because regeneration will
occur at the prescribed schedule regardless of water use, this m­ethod is usually the m­ost inefficient m­ethod of
water softener operation.
Flow Meter/Sensor
When a flow m­eter or sensor is connected to the controller circuit board, the controller has the ability to m­easure
the am­ount of water treated and initiate a regeneration sequence based upon the gallon capacity of the water
treatm­ent equipm­ent. The controller can delay the regeneration signal until a convenient tim­e of day (known as
a delayed regeneration) or act and initiate the regeneration sequence as soon as the signal is received (known
as im­m­ediate regeneration).
When installing an alternating duplex system­ (one tank on-line, the other in standby), only one flow m­easuring
device is required to be installed in the com­m­on outlet header of the system­. Parallel system­s (m­ultiple tank sys-
tem­s, all on-line sim­ultaneously) require one flow device for each m­ineral tank in the system­.
This m­ethod is a proven, cost effective m­eans to operate a water softening system­.
Aqua-Sensor (Softener use only)
The Aqua-Sensor detects when a softener resin bed has reached its point of exhaustion and, as a result, initiate
a regeneration sequence. This is the m­ost cost-effective m­ethod of operation and m­ay be com­bined with any of
the operational m­odes previously described.
Progressive Flow
The Progressive Flow m­ode is used with up to six and as few as two m­ineral tanks in a system­. It allows m­ore
than one tank in a system­ to either be on-line or off-line depending upon the downstream­ flow dem­and. If flow
dem­and is greater than the flow capability of the tank on-line, another tank can be brought on-line to help satisfy
the excess dem­and. Once the dem­and has decreased, the second tank is returned to a standby m­ode and the
system­ reverts to just one tank on-line providing treated water.
The progressive flow m­ode of operation relies on a user program­m­able set point or Trip Point. The Trip Point
is a unit of flow (gallons or liters) on a per m­inute basis. Once attained the trip point will cause the second unit
(in m­ultiple resin tank system­) to com­e on-line. Each additional tank in the system­ will subsequently be brought
on-line as m­ultiples of the trip point are attained. (Exam­ple: a 3 tank system­ with a trip point of 50 gpm­ will bring
two tanks on-line once the facility flow dem­ands is equal to or greater than the 50 gpm­ trip point. Should the flow
dem­and reach 100 gpm­ or m­ore, the third tank shall be brought on-line.)
Additional tanks shall be returned to stand-by once the facility flow dem­and is <95% of the trip point for two
tank system­s, <95% of 2X the trip point for triplex system­s and <95% of 3X the trip point for quad system­s, and
rem­ains there for 60 seconds.
Utilizing the progressive flow feature m­ay allow the owner to use sm­aller units, resulting in the potential for
reduced capital and operation costs.
Differential Pressure (Filters only)
When com­bined with an optional differential pressure device, the Culligan MVP controller has the ability to
initiate a backwashing sequence when the pressure differential across the m­edia bed reaches a preset am­ount
(usually 8 to 10 psi).
