The Model 31A00-1 Indoor/Outdoor Temperature Sensor is used for sensing outdoor or indoor temperature. It is coated with a sealant to withstand outdoor moisture and features a new, high accuracy temperature sensor that doesn’t need calibration.

The temperature can be used to activate programs for controlling temperatures in attics, garages, greenhouses, basements, wine cellars, and coolers. The temperature can be displayed on the console or spoken over the telephone. It can also report, log, alert, or generate an alarm if the temperature reaches freeze conditions or if the temperature goes above the high setpoint or drops below the low setpoint programmed in the system.
