** Humidistat will reduce cooling airow by 10% in high humidity.
*** Air ow is greater of COOL and HEAT when both electric heat and heat pump are operating.
ADJUST tap (+) will increase airow by 10%, while tap (-) will decrease airow by 12%.
ADJUST tap TEST will cause the motor to run at 70% of full airow. Use this for troubleshooting only.
At the start of a call for cooling there is a short run at 82% of airow for 7.5 minutes.
