1 When any A99 Series Temperature Sensor is connected to a standard A421 Control model, the range of displayed
temperature values is -40ºF to 212ºF or -40ºC to 100ºC.
The performance specifications are nominal and conform to acceptable industry standards. For
application at conditions beyond these specifications Johnson Controls shall not be liable for damages
resulting from misapplication or misuse of its products.
Type A99BA and A99BB: -40°F to 212°F (-40°C to 100°C)
Type A99BC: -40°F to 248°F (-40°C to 120°C)
1,035 ohms at 77°F (25°C) and 855 ohms at 32°F (0°C)
0.9°F (0.5°C) between 5°F and 167°F (-15°C and 57°C). Refer to the
