CONTROLLER ADVANCED FEATURES
8.4 Dosing Configuration
• EC/pH Control Step 1
• EC/pH Control Step 2
8.4.1 EC/pH Control Step 1
System injects ± depending on EC levels, auto-adjust to meet target levels. Set limits for controller adjustments when
levels are too high/low/
Example: If dosing Channel 1 is set by the grower to inject 10 liter/m3, the controller auto adjust range is 5 to 15
liter/m3 in order to meet the EC level.
8.4.2 EC/pH Control Step 2
• EC/pH coarse tuning: When way off target, faster/stronger correction
• EC/pH fine tuning: Off target is low, slow/light correction
• Control cycle: Delay time from fertilizer/Acid injection point to EC/pH sensors reading
• EC/pH averaging: Balanced reading from EC/pH sensors
• Dose boost off delay: Time clear water circulated through system after fertigation stops and Venturi closes
