CKT04 ADDENDUM

Dehumidification Select*
When Dehumidification mode exists, the circulating fan
output is reduced, increasing system run time, over cooling
the evaporator coil and ultimately removing more humidity
from the structure than if only in cooling mode.
The system can have Dehumidification operation in setting
“STD”, “A”, “B” or “C” of “Dehumidification Select” based on
dehumidification demand.
Setting “STD” allows for the widest compressor operation
range with lower CFM than Cooling mode.
In the Enhanced Dehumidification (setting A, B and C)
the indoor airflow is lower than Standard Dehumidification
(STD).
Setting “A” allows for the same compressor operation
range as standard Dehumidification with lower CFM
than standard dehumidification (STD). Setting “B”
limits compressor operation range and keeps high
dehumidification capacity. In setting “C” the system runs
fixed at 100% compressor and airflow. See Figure 1.
NOTE
: In high humidity environments, sweating on supply
ducts, cased coils or air handler cabinets can become an
issue in Enhanced Dehumidification operation. It is strongly
recommended covering then with 2" fiberglass insulation
for these installations.

and 0601BC or earlier models are different from this
specification. For details, see the Installation Manual
or Service Manual that matches the Major and Minor
