Feature	Filter Change Reminder	Room Temperature Calibration	Minimum Compressor On Time	Compressor Short Cycle Delay	Cooling Differential	Heating Differential
Adjustment Options	The filter change reminder can be adjusted from OFF to 2000 hours in 50 hour increments.	The room temperature display can be adjusted to read 3° above or below the factory calibrated temperature.	The minimum compressor run time can be adjusted from OFF to 3, 4, or 5 minutes. If 3, 4, or 5 is selected, the compressor will run for at least the selected time before turning off (although the fan may continue to run for a short time).	The compressor short cycle delay setting can be removed by selecting OFF.	The cooling differential setting is adjustable from 0.2°F to 2°F	The heating differential setting is adjustable from 0.2°F to 2°F.

Feature	Filter Change Reminder	Room Temperature Calibration	Minimum Compressor On-Time	Compressor Short Cycle Delay	Cooling Differential	Heating Differential
Factory default settings	OFF	0°F	OFF	On	0.5°F	0.4°F
Feature Description	This setting will flash FILT in the display after the elapsed run time to remind the user to change the filter. The OFF setting will disable this feature.	This setting allows the installer to change the calibration of the room temperature display so that, for example, the thermostat would read 72°F instead of 70°F.	The installer can select the minimum run time for the compressor to help protect the compressor from short-cycling.	The compressor short cycle delay setting will not allow the compressor to be turned on for 5 minutes after it was last turned off in order to protect the compressor.	The cooling differential is factory preset at 0.5°. This means that whenever the room temperature heats by 0.5° full degree from the temperature setting, the cooling system will turn on. If the cooling system turns on too often, increase the temperature differential.	The heating differential is factory preset at 0.4°. This means that whenever the room temperature cools by 0.4° from the temperature setting, the heating system will turn on. If the heating system turns on too often, increase the temperature differential.
