EFF1) 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 (or
EFF2 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.
NOTE: For Geothermal Heat Pumps, the airflow labels have been
changed from EFF325 and EFF350 to EFF1 and EFF2, respectively.
Nominal geothermal system airflows for these settings tend to be
different than the typical 325 and 350 CFM/ton values.
The dehumidify airflow, when set to NORMAL, the airflow 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.
• Cool: Quiet, Comfort, EFF325 (or EFF1), EFF350 (or EFF2), or Max.
Default = Comfort
• HP Heat: Comfort, EFF325 (or EFF1), EFF350 (or EFF2), or Max.
Default = Comfort
• Dehumidify: Normal or High. Default = Normal
6.3.3.3. Furnace Staging
This option controls the staging of the furnace and selects the minimum
amount of time low stage must operate before high stage is activated.
SYSTEM setting will allow the Infinity Zone Control to determine
furnace staging. LOW will only run the low stage of furnace heat.
LOW-MED will run the low and medium stages (2 stages of heat). MED
will only run the medium stage of heat. MED-HIGH will run the
