PROGRESSIVE RECOVERY
The Progressive Recovery feature, if enabled by the installer, allows the thermostat to activate the
heating and cooling equipment PRIOR to a scheduled event in order to reach the desired temperature
at the start of that scheduled event. When a heating or cooling call is active for Progressive Recovery,
the current event schedule will ash.
EXAMPLE: Set the WAKE time to 6:00 am, and the temperature to 70°. The heat will come on before 6:00
am, so the temperature is 70° by the time you wake at 6:00 am�
