2.2.5 54BEC Pre-Control
Use this option in hydraulic pre-control systems in greenhouses. When collecting excess water from drains, the
grower can set an EC target before water goes through an irrigation system. This method reuses excess fertilizer and
water, recycling them for a second irrigation run.
Note: An EC Pre-Control valve relay must be defined by a technician at installation.
