PERFORMANCE DATA
AIRFLOW DELIVERY — COOLING, HEATING, ELECTRIC HEATING MODES
The FCM4X fan coils will provide airflow at a rate that is requested by the wall control during air conditioning or heat pump heating (without electric heat) modes. The nominal airflow for both heating and cooling modes is 350 cfm/ton nominal size of the outdoor unit installed. The airflow actually requested by the wall control is modified by its internal algorithms for zoning, comfort or efficiency concerns. Refer
to the documentation for the wall control for more information on how the wall control controls the fan coil. Safe operation of electric heaters requires airflow delivery at or above the minimum CFM for electric heater application listed in the chart below. The fan coil will adjust its airflow delivery to maintain safe airflow as operating mode and staging conditions require.
