Setup

Notes

Contact Set

[typical Aquatic uses

are sensor flow

switch, main

recirculation flow

switch, auto fill

switch, or low

chemical level alarm]

User selects Contact Set

Contact sets are ON when closed and OFF when

open. ON time is logged.

Contact sets used for interlocking, prevent relays

from turning ON when contact set is OFF, or open.

Contact sets may be configured as ‘inverted’ to act

and display as ON when they are OFF.

6.4. Frequency Controlled Pumps

Feed Rate Setting

The controller knows the pump’s mL/stroke and maximum stroke rate (Maximum SPM), based on the

ProMinent pump model entered, or the values you entered for ‘Other’.

Once you select the pump feed method or control mode, the controller sets the optimum Pump Speed.

ORP

TurnOFF :

pH or ORP setpoint

100%ON :

pH or ORP setpoint

Proportional control.

pH: Acid

As the pool or spa chemistry changes from swimmers or

Chlorine feed, the pH rises.

The acid pump is OFF at pH < TurnOFF.

The pump speed increases linearly between TurnOFF

and 100% TurnON setpoints.

ORP: Oxidant

As the pool or spa operates, contaminants are

introduced, Chlorine is consumed and the ORP falls.

The hypochlorite pump is OFF at ORP > TurnOFF

The pump speed increases linearly between TurnOFF

and 100%ON setpoints.

Base

mL/minute setpoint

Pump feeds at user set rate unless flow switch interlocks

(turns OFF) feed. [Not normally used in pool and spa

applications.]

Cycling

User sets cycle period in

minutes and ON volume in mL.

Pumps user set volume (1mL to 10L) at maximum SPM

at the start every user set period if above TurnON

setpoint. [Not typically used in Pool and Spas]
