P2C - Connecting a Hunter Clik Weather Sensor

A Hunter weather sensor or other micro-switch-type weather sensors can be connected to the Pro-C® Controller. The purpose of this sensor is to stop automatic watering when weather conditions dictate.

  1. Remove the metal jumper plate that is attached across SEN-2 and COM.
  2. Connect one wire from the sensor to the SEN-2 screw terminal and the other sensor wire to the COM terminal. When the weather sensor has deactivated automatic watering, OFF will appear on the display.

IMPORTANT: The SEN-1 terminal will only be used for the Solar Sync Sensor. Learn More

IMPORTANT: The Manual single-station function ignores any attached sensor and will allow watering.
