To Activate The Switch On Increasing Flow:
1 - Set the flow rate to the desired set point and allow it to stabilize for 2 minutes.
2 - Turn the potentiometer counter-clockwise until the central LED turns red.
3 - Turn the potentiometer clockwise until the central LED changes to a blinking green.
4 - Continue to turn the potentiometer clockwise until the first 2 green LEDs in the bar
graph turn on.
In this mode the CF12 will activated on or above the set point. If there is a decrease of
flow, the CF12 will de-activate. When the flow rate reaches the set point, the CF12 will
activate.
To De-Activate The Switch On Decreasing Flow:
1 - Set the flow rate to the desired set point and allow it to stabilize for 2 minutes.
2 - Turn the potentiometer clockwise until the central LED is blinking green.
3 - Turn the potentiometer counter-clockwise until the central LED turns red.
4 - Continue to turn the potentiometer counter-clockwise until the 2 red LEDs in the bar
graph are off.
In this mode the CF12 will de-activate on or below the set point. If there is an increase of
flow the CF12 will activate. When the flow rate reaches the set point, the CF12 will de-
activate.
Detecting level:
1 - Fill the tank until the probe of the CF12 is fully submerged. Turn the potentiometer
counter-clockwise until the central LED turns red. With the central LED red, turn the
potentiometer clockwise until the central LED changes to a blinking green.
2 - Continue to turn potentiometer clockwise until all green LEDs in the bar graph turn on.
3 - In order to be sure that the adjustment is not at a critical state give the potentiometer
an additional quarter turn clockwise.
