How ET Manager Cartridge Works

Installs easily into ESP-LX Modular controller converting it to a weather based controller. Essentially preventing watering until moisture loss in the landscape reaches a predetermined amount (i.e. acts much like the fuel warning light to your gas tank). ET Manager Cartridge calculates moisture loss based upon:

• Hourly Rain and ET data received from ExactET’s local weather network.
• Site specific information (e.g. slope, plant type, root depth, soil type, sprinkler system) programmed in using the Setup Wizard.
