PROGRAM PUMP SETTINGS
General Guidelines
The host device must have the ability to interface with the pump via a 12-24 VAC/VDC
signal. For typical water softener installation, the controller provides the ability to program
the amount of water that passes through the water softener in gallons per signal (referred
to as Water Volume per Signal in 2a below) and the duration of the signal in seconds
(referred to as Water Softener Chemical Feed Duration in 2b below).
Refer to the specific water softener manual for instructions on how to program the settings
and make the signal connections to the metering pump.
1. Determine the desired water volume (in gallons) that will pass through the water
softener to require the (water softener) controller to send a signal to the metering
pump (e.g. at every gallon).
NOTE: Smaller water volume between signals generally allows for more even
chemical dispersion.
2. Calculate the Water Softener Chemical Feed Duration in Seconds.
The water softener chemical feed duration (in seconds) is the programmed amount of
time that the (water softener) controller is continually activating the metering pump
(to dispense chemical).
