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.
- Remove the metal jumper plate that is attached across SEN-2 and COM.
- 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
