Resume / Adaptive Intelligent Recovery Capability
Brings the room temperature back to the programmed temperature at the set time, even when you may have manually over-ridden the program in the interim which will maximize comfort and energy savings.
Indoor Temperature Sensing Capability
Some thermostats provide for wiring to an accessory called an indoor sensor. The indoor sensor mounts in the home living space away from the thermostat, and tells the thermostat what the temperature is in that area. The thermostat will then use the temperature from the sensor to indicate the home's current comfort level, instead of just the temperature near the thermostat.
Allows easier viewing of disply screen in the dark.
Outdoor Temperature Sensor Capability
When used with an outdoor air sensor, this features allows the thermostat to sense the outdoor temperature and indicate such on the screen. Also allows some thermostats to automatically decide whether to heat or cool the home based on outside temperatures.

Having this feature will store your set temperature or temperature schedule. In the event of a power failure, you won't have to reprogram the thermostat when the power returns.
Humidifier Panel Indication

This feature allows the thermostat to automatically switch from heating to cooling based on the temperature inside. This is useful between seasons when heating may be needed at night, and cooling during the day.
Indicates that you may select to allow only individuals who have a numeric code (which you create) to change the temperature or settings on the thermostat. This feature is useful for thermostats located in public spaces, or to keep children from operating the thermostat.
Allows you to program your thermostat to operate your heating/cooling system at a minimum when you leave on vacation (to save money), and then automatically return the temperature to a normal comfort setting just before you arrive home. Having this capability will mean that when you return, your house will be nice and comfortable.
