Example: A grower wants to lower the EC as the kPa decreases. He sets this screen to reduce the increase in EC to
match the decreasing VPD levels.
2.8.7 62BTemperature Influence on Target EC
You can adjust the EC based on the air temperature. As the temperature rises or falls, the program can increase or
decrease the EC level according to your requirements.
1. In Installation > Analog Input define:
a. a sensor as EC
b. an air temperature sensor

Note: You can verify the EC status using Hot Key Screen 4, the temperature sensor status using Hot Key
Screen 6.
2. In Configuration > Dosing Channel Configuration set React to EC.
3. In Configuration > Dosing Configuration > EC Control, set EC Control to Yes.
