ENERGY EFFICIENT RECOVERY

When turned on, the thermostat will look up to two hours before the next event and anticipate when to turn on to reach the desired temperature.

NOTE: This will not allow the second stage to turn on until 20 minutes before the event.

DEADBAND SETPOINT

Deadband is used only when the AUTO CHANGEOVER feature is enabled. The deadband is the temperature difference between the heating and cooling setpoints. This is adjustable from 3-8°F (2.0-4°C).
