Accuracy
Indoor Temperature
Operating temperature range: 32°F to 122°F (0°C to 50°C)
Accuracy: ± 2°F 32°F to 122°F (0°C to 50°C)
Resolution: 0.1°F
When above 122°F (50°C) the temperature sensor should continue to read the correct temperature
as long as the LCD display continues to function.
When below 32°F (0°C) the temperature sensor should continue to read correctly as long as the LCD
display continues to function.
Outdoor Temperature
Operating temperature range: -40°F to 140°F (-40°C to 60°C)
Accuracy: ± 2°F 32°F to 122°F (0°C to 50°C)
Accuracy: ±4°F
