Frequently Asked Questions

Q: What happens if I don’t upgrade? What functionality will I lose?

A: The controller will continue to irrigate but will no longer be receiving daily site-specific ET weather data and irrigation schedules will not be optimized. You will not be able to remotely manage or control the system from a laptop or mobile device and no longer receive alerts and notifications of system issues. The benefits of an ET-based smart irrigation controller you have become accustomed to will not be available, the controller will be functioning as a basic irrigation timer that is managed manually on the face plate.

The following features will NO longer work:

  • WeatherTRAK Central internet control, reporting and alerting
  • WeatherTRAK daily ET weather data
  • Automated daily schedule adjustments
  • WeatherTRAK Mobile access

Q: What happens to all the settings and data from my Pro2 controller if I opt to upgrade?

A: All settings and data will automatically transfer to the upgraded (NEW) serial number when it is activated. Users will need to provide old serial number when activating.

Q: Is the Pro2 controller still supported? Will customer service still help me? Will I be able to order replacement parts?

A: The Pro2 controllers will still be supported by customer service, but without communication, ability to provide support will be limited. If your controller is still under warranty and you experience hardware problems, please contact customer support and they will be able to assist you.

Q: Who will install the upgrade for me?

A: Upgrading is simple! Customers are responsible for installing and activating the upgrade with our easy to follow installation instructions: Installation Instruction for LC 2G to LTE. If you would like a recommendation for a local installer, please ask us.

Q: What is I want to upgrade to a WeatherTRAK OptiFlow XR controller instead of an ET Pro3?
