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).
HUMIDITROL
If the HUMIDITROL accessory is present in the HVAC equipment, this feature should be enabled.
Otherwise, it should be disabled.
