Product Overview

Compatibility & Installation Notes

Check Wi-Fi reception at the mounting location and record existing zone wiring before replacing a controller. Use the supplied AC adapter with compatible 24V AC irrigation valves; DC transformers are not supported. Install and close the outdoor enclosure according to Rachio’s instructions. Have a qualified installer handle line-voltage connections. A supported flow sensor is required for flow measurements; electrical wiring alerts alone do not measure water flow. Rachio’s four-year Pro warranty requires a qualifying sale and installation by a Rachio Pro.

Frequently Asked Questions

How many zones does 16ZULWC-PS control?

16ZULWC-PS controls up to 16 irrigation zones and has a separate master-valve/pump-relay connection.

Is the outdoor enclosure included?

Yes. 16ZULWC-PS is the Pro package with a weatherproof outdoor enclosure and a 6-foot pigtail.

Which Wi-Fi bands does it support?

The controller supports both 2.4 GHz and 5 GHz Wi-Fi. Check signal strength at the installation location before mounting.

Does the controller measure flow without a sensor?

No. Water-flow measurements require a compatible flow sensor. Faulty-wiring alerts monitor an electrical issue and do not replace a flow sensor.

Why Buy from Big Frog Supply?

Choose 16ZULWC-PS for a landscape with up to sixteen valve circuits that also needs an outdoor controller enclosure. The larger zone capacity accommodates separate lawn and planting-bed schedules, while the supplied weatherproof cabinet and 6-foot pigtail simplify selecting the correct outdoor package. Its screw terminals distinguish the Pro hardware from easy-press consumer models.
