Pump OFF
● 4 = ON/OFF chlorine (this option is typically used for chlorination or
alkalization; the pump activates when the measurement is lower than the
"working threshold – ½ hysteresis" value and deactivates when the
measurement exceeds the "working threshold + ½ hysteresis" level).
● 5 = Proportional chlorine (the pump is definitely active when the measurement
is lower than the "working threshold – ½ hysteresis" value and definitely off
when the measurement is greater than the "working threshold + ½ hysteresis"
level, while for measurements between these limits the operating time of the
pump is proportional to the distance of the measurement from the limits. The
time base is fixed (90 seconds) and operation follows the trend shown in the
table below):

● P5: This parameter allows setting the working threshold used when the pump
operates in automatic control.
● P6: This parameter represents the intervention hysteresis around the working
threshold; in the case of ON/OFF controls, it can be set between zero and 2.00
