Auto-Changeover: A mode in which the thermostat turns on the heating
or cooling based on room temperature demand.
Cool Setpoint: The warmest temperature that the space should rise to
before cooling is turned on (without regard to deadband).
Deadband: The number of degrees the thermostat will wait, once a
setpoint has been reached, before energizing heating or cooling.
Dehumidify: To reduce the amount of moisture in the air.
Differential: The forced temperature difference between the heat
setpoint and the cool setpoint.
Heat Setpoint: The coolest temperature that the space should drop to
before heating is turned on (without regard to deadband).
Humidify: To increase the amount of moisture in the air.
Icon: The word or symbol that appears on the thermostat display.
Mode: The current operating condition of the thermostat (i.e. Off, Heat,
Cool, or Auto).
Non-Programmable Thermostat: A thermostat that does not have the

the thermostat into unoccpied settings.
Programmable Thermostat: A thermostat that has the capability of
running Time Period Programming.
Reheat: Runs the cooling and 2nd stage strip heaters at the same time
in order to dehumidify the air without significantly cooling down the
room temperature.
Time Period Programming: A program that allows the thermostat to
automatically adjust the heat setpoint, or cool setpoint, based on the
time of the day.
