Connecting a Weather Sensor (Not Included)

A Hunter Mini-Clik® rain sensor or other type of micro-switch weather sensor may be connected to the Pro-C. The purpose of this sensor is to stop watering when precipitation is sufficient. The sensor connects directly to the controller and allows you to easily override the sensor by using the Rain Sensor bypass switch on the controller.

  1. Route the wires from the rain sensor up through the same conduit used for valve wiring.
  2. Remove the jumper from the two SEN terminals.
  3. Connect one wire to the SEN terminal and one to the other SEN terminal.

NOTE: If the rain sensor switch is left in the ACTIVE position and no sensor is connected and the jumper has been removed, the display will read SEN OFF and no irrigation will occur. To eliminate this problem when no sensor is connected, leave the switch in the BYPASS position or install a short jumper wire between the sensor terminals.

NOTE: If the sensor interrupts a watering cycle and resets before the cycle would have finished, the remaining portion of the watering cycle is terminated.

Testing a Weather Sensor

The Pro-C provides simplified testing of a rain sensor when the rain sensor is wired into the sensor circuit. It also provides the user the ability to override the rain sensor when necessary to perform system inspections and manual watering.

  • Testing the Rain Sensor - The user can manually test the proper operation of the rain sensor by running a manual "all stations cycle" or by activating the system using the one touch manual method. During a manual cycle, pressing the test button on the Mini-Clik® will interrupt watering.
  • Overriding the Rain Sensor - The SRR remote control device (single station operation only, not programs A, B, or C) and manual single station function on the Pro-C dial will override the rain sensor. This function provides the users the ability to operate the system even though the rain sensor has shut the system off.
