PERFORMANCE DATA
AIRFLOW DELIVERY — COOLING, HEATING, ELECTRIC HEATING MODES
The FCM4X fan coils with the Observert Communicating Wall
Control 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 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.
