To Set Airflow: (1) Select model and desired High Stage Cooling Airflow. Determine the corresponding tap (A, B, C, or D). Set dip
switches S3-1* and S3-2* to the appropriate ON/OFF positions. (2) Select model and desired High Stage Heating Airflow. Determine
The corresponding tap (A, B, C, or D). Set dip switches S4-3* and S4-4* to the appropriate ON/OFF positions. (3) Selecting Airflow
Adjustment Factor: For 0% trim set S5-2* to OFF (trim disabled). If trim is desired set S5-2* to ON (trim enabled) and set S3-3* and S3-4*
to appropriate ON/OFF positions. Tap A is +5%, Tap B is -5%, Tap C is +10%, Tap D is -10%. To Set Comfort Mode: Select
Desired Comfort Mode profile (see profiles above). Set dip switches S4-1* and S4-2* to the appropriate ON/OFF positions.
Dehumidification: To enable, set switch S5-1* to ON. Cooling airflow will be reduced to 85% of nominal value during cool call. To
disable, set switch S5-1* to OFF. Continuous Fan Speed: Set dip switches S5-3* and S5-4* to select one of 4 continuous fan speeds
(25%, 50%, 75%, or 100%). “See installation manual for details” *the “S” number refers to one of four labeled dip switch section each
containing 4 individual dip switches. The following number refers to the individual labeled dip switch within that section.
