A Hunter CLIK sensor or closed circuit type weather sensors can be connected to the X2. The purpose of this sensor is to stop automatic watering when weather conditions dictate.
Remove the metal jumper plate that is attached across the two SEN terminals inside the controller.
Connect one wire to one SEN terminal and the other wire to the other SEN terminal.
When the weather sensor has deactivated automatic watering, the OFF, and 
icon will appear on the display.
The X2 provides simplified testing of a rain sensor when the sensor is wired into the sensor circuit. You can manually test proper operation of the rain sensor by running a MANUAL CYCLE or by activating the system using the One Touch MANUAL START. During the Manual cycle, pressing the test button on the Mini-Clik® will interrupt watering.
NOTE: Do not use Manual option located on the dial position to test sensor operation. Manual One Station will override an active (or wet) sensor.
If the rain sensor is interrupting irrigation, you can bypass it by using the bypass switch on the front of the controller. Slide the switch to the SENSOR BYPASS position to disable the rain sensor from the system to allow for controller operation. You can also bypass the weather sensor for manual operation by using the MANUAL – ONE STATION function.
