1.
All furnaces ship as high speed for cooling. Installer must adjust blower speed as needed.
2.
For most jobs, about 400 CFM per ton when cooling is desirable.
3.
Do not operate above .5" w.c. ESP in heating mode. Operating CFM between .5" and .8" w.c. is tabulated for cooling purposes only.
4.
Continuous fan speeds of 25%, 50%, 75% of maximum cooling airflow are available when using a communicating thermostat and 25%, 50%, 75%, 100%
of maximum cooling airflow are available in legacy mode by setting dip switches
