IDENTIFICATION
Model Number, Serial Number and Software Version are displayed within this menu. A model number check will help determine
if the equipment shared data is correct for the unit. If the model number is not correct, even though very rare, a memory card
is available to load the proper data.
SENSORS
The outdoor ambient temperature and coil temperature are displayed in the Sensor Menu. This information can be used for
troubleshooting purposes.
COOL S ET-UP
This menu allows for the adjustment of several cooling performance variables. Cool Airflow Trim (range from -10% to 10% in 2%
increments), Cool Airflow Profiles, Cool Fan ON Delay, Cool Fan OFF Delay and Dehumidification Select (enable or disable
dehumidification) can be adjusted in this menu. See the following images showing the four cooling airflow profiles.
• Profile A (default) provides only an OFF delay of one (1) minute at 100% of the cooling demand airflow.

• Profile B ramps up to full cooling demand airflow by first stepping up to 50% of the full demand for 30 seconds. The motor then
ramps to 100% of the required airflow. A one (1) minute OFF delay at 100% of the cooling airflow.

STATUS
The current system operational mode and requested indoor CFM is reported in this menu. This information can be used for
troubleshooting purposes.
HEAT S ET-UP
This menu allows for the adjustment of several heating performance variables. Heat Airflow Trim (range from -10% to 10% in
2% increments), Heat Fan ON Delay, Heat Fan OFF Delay, Defrost Interval and Compressor Delay can be adjusted in this
menu. Defrost Interval determines the amount of compressor run time between defrost cycles. Compressor delay selects a
compressor off time after a reversing valve shift.
