CONNECTING SENSORS OR FLOW METERS
(OPTIONAL)
Pro-HC Controller supports most open/closed contact type of sensors, such as Hunter
rain and soil moisture sensors.
1. Connect one sensor wire to COMMON on the controller.
2. Connect the Normally Closed or Normally Open wire from the sensor to SEN-1 or
SEN-2 on the controller and configure in the Hydrawise app.
For full details, refer to the instructions
