Smart Response
®
Technology: This feature allows the thermostat to “learn” how
long the furnace and air conditioner take to reach programmed temperature set-
tings, 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 befor
e 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 (RTH7500 only
): 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 thermo-
stat 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).
