The thermostat reads the indoor humidity level from the field
setting menu and allows the user to set a dehumidification
target based on these settings. The thermostat controls the
humidity level of the conditioned space using the cooling
system. Dehumidification is engaged whenever a cooling
demand is present and structural humidity levels are above
the target level. When this condition exists the circulating
fan output is reduced, increasing system run time, over cool-
ing the evaporator coil and ultimately removing more humidity
from the structure than if only in cooling mode.
For effective dehumidification operation:
• Please revise it to read ensure Dehumidification is NOT
set to "OFF."
• If "STD", system run lower CFM than normal cooling
mode.

Dehumidification operation in setting "A", "B" or "C"
based on dehumidification demand.
In the Enhanced Dehumidification the indoor airflow is
lower than Standard Dehumidification. Setting "A" allows
for the widest compressor range with lower cfm than
standard dehumidification. 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.
• Verify the cooling airflow profile (cool profiles) is set to
"Profile D".
• For additional dehumidification control, airflow settings
are field adjustable and can be fine-tuned to a value that
is comfortable for the application from a range of Cool
Airflow Trim.
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 recomended
covering them with 2" fiberglass insulation for these instal-
lations.

QUIET MODE enables the system to operate at decreased
compressor and fan speeds to satisfy quiet driving.
QUIET MODE is initiated by user's setting ("ON" or "OFF".
Default is "OFF").
NOTE:
"NOISE DOWN LEVEL" is initiated by user's setting.
("LEVEL" "1" , "2" or "3" . Default is "LEVEL" "2" . "LEVEL" "3"
is the most quiet.)
If during operation the capacity demand is high, then the
quiet mode function will be temporary off by capacity prior-
ity function to return the room temperature to the set point.
(Default capacity priority setting is ON)

ZONING MODE is recommended to use when the zoning
controller and dampers are installed. This mode allows the
system to run with lower indoor air flow comparing with normal
operation when the cool or heat demand is low. The ZONING
MODE is disabled in factory default setting. It can be activated
through the thermostat user menu and 7-segment display.
c
irculation selection
This setting can be used to switch circulation factor ON and
OFF to avoid automatically increasing the indoor CFM by
circulation control.
When it is ON, the system may increase indoor CFM to cir-
culate indoor air in the event the outdoor control detected low
evaporative temperature.
When it is OFF, even if the outdoor control detects low evapora-
tive temperature, it will NOT increase CFM.
ON is reccomended generally, but when a zoning controller is
connected, it is recommended to be OFF on this setting to avoid
unexpected high static pressure.
s
et thermostat to aDjust maximum compressor speeD
Maximum compressor speed at which the outdoor unit will
operate can be changed using thermostat. Maximum com-
pressor speed can be changed to get the required capacity
or efficiency. Once the maximum speed is set, the system
operates between the set maximum speed and default low
speed.
