6.3.1.6. Smart Recovery On/Off

NOTE: "Smart Recovery" refers to transitions between and among the Home, Sleep and Wake

modes. Moving from the Away mode to any other mode is covered by the "Smart Setback"

feature.

Smart Recovery applies to programmable operation only. Smart Recovery causes the system to

ramp the system target setpoints to those for the next programmed schedule period to help save

energy during period transitions. Smart Recovery will start recovery 90 minutes prior to

schedule change in both heating and cooling mode. After the selection is made, touch SAVE.

• Smart Recovery: On or Off. Default = On

NOTE: The "Temperature Units Display" set-up section has been moved to the Homeowner

Screens. See the Owner's Manual for more information.

6.3.2. Fan Coil

First touch SETUP, then touch FAN COIL to set up the parameters for the fan coil unit.

6.3.2.1. Airflow

This option allows the installer to select the appropriate air flow based on the needs of the

installation. The QUIET airflow means the minimum cooling airflow that the system can safely

run (typically 300 CFM/ton). Use this setting if duct noise is a severe problem. Note that duct

sweating in high humidity environments could become an issue at low airflows. The

COMFORT airflow means airflow is varied depending on humidity and temperature demand

settings. This selection enables the full dehumidify and comfort capabilities of the system. The

EFF325 airflow is a fixed airflow used to achieve specified ratings – no dehumidification

airflow reduction is performed. This is nominally 325 CFM/ton, but will vary if a 2-stage

outdoor unit is used. The EFF350 airflow is a fixed airflow used to achieve specified ratings –

no dehumidification airflow reduction is performed. This is nominally 350 CFM/ton, but will

vary if a 2-stage outdoor unit is used. The MAX airflow is a fixed 400 CFM/ton. No

dehumidification airflow reduction is performed.

The dehumidify airflow, when set to NORMAL, is allowed to adjust to a minimum to satisfy

the dehumidification call. When set to HIGH, the minimum airflow during the dehumidify

mode is increased to reduce duct and register sweating. Also the airflow increases minimum

airflow during normal cooling operation to help reduce duct sweating.

After the selections are made, touch SAVE.
