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 tempera-
ture 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 conditioning 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).
