9.2.2.1 Radiation Influence on EC
This function enables adjusting the EC based on solar radiation. Solar radiation increases the greenhouse
temperature. Adjust the EC according to your crops’ requirements.
To set the Radiation Influence:
1. In Installation > Analog Input, define a sensor as EC.
2. In Configuration > Dosing Channel Configuration, set React to EC.
3. In Configuration > Dosing Configuration > EC Control to Yes.
4. In Program > Irrigation, select Radia./EC.
5. Define the Radiation set points (w/m2).
6. Define the EC change in percentages.
7. Set ACTIVE/SOURCE to Yes.
8. Press Menu and confirm changes.
9. In Program > Dosing Program:
a. set the Target EC
b. set EC Dosing Method to Qty.
Example: As sunlight increases, a crop requires higher EC levels. The following screen illustrates increasing in the
EC based on radiation. Since Irrigation Junior Pro calculates the increase in EC proportionally, there will be a 7.5%
increase when the radiation reaches 60 w/m2.
