Special features

Auto Changeover: When set to Auto, the thermostat automatically selects heating or

cooling depending on the indoor temperature. Adaptive Intelligent Recovery: 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.
