PINPOINT pH Controller
***This example is for a CO2 dosing system.
When CO2 is added to water; it will lower the pH
of the water.
-You must first select an acceptable range of pH
like 6.6 to 6.4
At any pH value over 6.6 Outlet #1 will be
energized and the CO2 will bubble into the water
until the pH reaches the level of 6.4 At the 6.4
level the CO2 will shut off and stay off until the pH
rises above the 6.6 level.
-To achieve these setpoints, the selector switch
should read 6.60 when placed in the HI position
and 6.20 when put in the LO position. The Center
Value is the number that is exactly between the HI
and the LO. The Center Value in this example is
6.40 This Center Value must be calculated; it is not
displayed.
-To arrange these settings (HI=6.60, LO=6.20,
Center Value=6.40) into the controller you must do
the following 2 part adjustments.
1-Put the selector switch to the HI position and
note the number. Then put the switch to the LO
