Special features
Smart Response
®
Technology: This feature allows the thermostat to
“learn” how long the furnace and air conditioner take to reach programmed
temperature settings, so the temperature is reached at the time you set.
For example: Set the Wake time to 6 am, and the temperature to 70°. The
heat will come on before 6 am, so the temperature is 70° by the time you
wake at 6. The message “Recovery” is displayed when the system is
activated before a scheduled time period.
Compressor Protection: This feature forces the compressor to wait a few
minutes before restarting, to prevent equipment damage. During the wait
time, the message “Wait” is displayed on screen.
Auto Changeover: This feature is used in climates where both air condi-
tioning and heating are used on the same day. When the system is set to
Auto, the thermostat automatically selects heating or cooling depending on
the indoor temperature. Heat and cool settings must be at least 3 degrees
apart. The thermostat will automatically adjust settings to maintain this
3-degree separation.
CAUTION: To avoid possible compressor damage, do not use Auto Changeover if the
outside temperature drops below 50°F (10°C).
