series include a freezer sensor to signal building/irrigation management
systems when temperature hits the freeze thresholds.
NOTICE

Without the connection kit, the sensor is a passive component that
does not communicate with any other device. (The kit can also be used
to retrofit existing installations. For ordering details, see "Add-on Sensor
Connection Kit.") BMS/IMS only.
