Brand: K-Rain SKU: 3206
Product Overview
The K-Rain 3206 is a radio-frequency module with a short-distance antenna for compatible PRO EX 2.0 irrigation controllers. It installs at the controller's designated RF-module connection and provides the receiving hardware needed for supported K-Rain wireless accessories that communicate through the PRO EX 2.0 radio system.
This is an accessory module, not a complete controller. It does not add irrigation stations, provide Wi-Fi service by itself, include a weather sensor, or function as a handheld remote. It also should not be confused with the separate long-range antenna and coax-cable assembly used where the approved installation requires a different antenna arrangement.
Before ordering, inspect the controller model, existing modules, installed accessories, and the contents of any previously purchased kit. Some compatible wireless-accessory kits may already include the required receiver hardware, while a standalone sensor may require the 3206 to communicate with a standard PRO EX 2.0 controller. Actual radio performance depends on antenna placement, building materials, terrain, nearby electrical equipment, and line-of-sight conditions. Install the module only in the approved controller location and follow current K-Rain pairing and antenna instructions.
