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 (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 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). 16 RTH7400/RTH7500 Battery replacement Grasp thermostat and pull to remove from wallplate Batteries are optional (to provide backup power) if your thermostat was wired to run on AC power when installed.
