*This CFM is not approved for use with highest kW heater size.
**Humidistat will reduce cooling airflow by 10% in high humidity.
***Airflow is the greater of the COOL and HEAT values when both electric heat and heat pump are operating.
NOTES:
Adjust tap (+) will increase airflow by 10%, while tap (-) will decrease airflow by 12%.
Adjust 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.
