Indoor Blower Options

• Humidity Control for Cooling — This unit is capable of providing
additional dehumidification during the cooling mode by reducing
the airflow when humidity is above the set point. A conventional
field supplied humidistat is required to control this function.
1. Cut the BK jumper on the AFC.
2. Using a field supplied humidistat, wire 24VAC Hot to one side of
the humidistat. Wire the other side of the humidistat to the BK
terminal on the low voltage terminal board. See wiring diagram.
• Pulse Width Modulation (PWM) — Typically used with A/
TCONT402 or zoning control.
1. The BK jumper must be cut on the AFC.
— Do Not cut the Y0 jumper.
• All zoning applications MUST be set to Constant CFM mode.
