-
Relay n° 3, 4 Free Chlorine;
-
Relay n° 5 Rx;

It is the windows deserved to relay:
SETPOINT: Set the value of the setpoint in ppm
HYSTERESIS: Set the range around the setpoint (setpoint ± hysteresis is the range)
DOSING MODE: Set the Relay mode:
- HIGH: The Relay closes when the measures is lower of setpoint ± hysteresis, and open
when the measure is upper of setpoint ± hysteresis
