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.
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, 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.
• Cooling Airflow: Quiet, Comfort, EFF325 (or EFF1), EFF350 (or
EFF2), or Max. Default = Comfort
• Heating Airflow: Comfort, EFF325 (or EFF1), EFF350 (or EFF2), or
Max. Default = Comfort
• Dehumidify Airflow: Normal or High. Default = Normal
6.3.2.2. Altitude
• Static Pressure selection: 0 to 10,000 ft. This is used to correct the
static pressure readings the system performs.
