C7089U Outdoor Sensor: Negative temperature coefficient
(NTC) means that resistance decreases as the
temperature increases. See Table 13 in the Operation
section for sensor resistance characteristics.

coefficient (NTC), means that resistance decreases as the
temperature increases. See Table 14 in the Operation
section for sensor resistance characteristics.
