**Humidistat will reduce cooling airflow by 10% in high humidity.
***Airflow is greater of Cool and Heat when both electric heat and heat pump are
operating.
NOTES:
■ Adjust the Control Board Tap (+) will increase airflow by 10%, while the Control Board
Tap (-) will decrease airflow by 12%.
■ Adjust the Control Board Tap (-) test will cause the motor to run at 70% of full airflow.
Use this for troubleshooting only.
■ At the start of a call for cooling, there is a short run at 82% of airflow for 7.5 minutes.
■ At the end of a call for cooling, there is a blower delay of 1 minute.
