Stages of Heat

The number of terminals on the thermostat that can be used to individually control separate heating functions. Many furnaces that are called two stage heaters will require at least a two stage thermostat to operate appropriately. You may also choose a multiple stage thermostat when pairing different heating equipment. Such as a heat pump and a furnace.

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.

Outdoor Temperature Sensor Capability
No
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.

Indoor Temperature Sensing Capability
Yes
Auto Changeover

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.
