Bring app-based irrigation control to an indoor location with the 16-zone 16ZULWC-PRO-BLI. Its black faceplate and stainless-steel screw terminals distinguish the Pro hardware from a standard consumer controller.

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. Mount indoors in a protected location. A compatible weatherproof enclosure is required for outdoor installation. 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-PRO-BLI control?

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

Can this indoor model be mounted outside?

16ZULWC-PRO-BLI is supplied as an indoor controller. Add a compatible Rachio weatherproof enclosure before installing it outdoors.

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-PRO-BLI when an indoor installation needs more than eight zones or room for additional separately controlled valve circuits. Sixteen terminals and a dedicated master-valve/pump-relay connection help organize a larger irrigation layout, while the black faceplate and screw terminals retain the indoor Pro format. Add an enclosure only if the mounting location will be outdoors.
