Third Party Rain/Freeze Sensors
Third-party rain and freeze sensors typically operate by breaking the connection between the field
common wire and the controller.
Sensors must be wired according to Calsense requirements (Figure 20
). If using a different weather
sensor, including a wireless sensor, contact Calsense at [phone] for a wiring diagram.
Caution: DO NOT
install a rain and/or freeze sensor other than directed as doing so will disable some of
the controller's features.
