C-Adjusting Unit CFM
The supply CFM can be adjusted by changing Unit
Controller settings. Refer to table 4 for menu paths and
default settings. Record any CFM changes on the
parameter settings label located on the inside of the
compressor access panel.
IMPORTANT - The default value for Cooling Low CFM
is lower than a traditional singe- or two-speed blower. If
operating the unit with a 2- or 3-stage controller (2- or
3-stage thermostat, DDC controller, etc.), it is
recommended to increase the Cooling Low CFM
default value to a suitable level for part load cooling
(typically 60% of full load CFM).
