Operational Test Modes
Operational test modes are a variety of tests used to
evaluate different modes of operation. Operational tests
include Dehumidification, Comfort Cooling Heating and
Fan Only modes.
Operation test modes will time out
after 30-minutes.

T5: Enter (Select and Set Value)
T6: Scroll Down/Decrease Value
Occupancy
Occupancy:
This input can be toggled between
OCCUPIED, UNOCCUPIED, and OFF. OCCUPIED forces the
unit into an occupied state. UNOCCUPIED forces the unit
into an unoccupied state. OFF allows the occupancy
function to perform as normal.
Dehumidification
Dehumidification Test Mode:
This mode is used to test
unit response to a call for space dehumidification. When
activated the space temperature and humidity will be
overridden to 72
˚F and 70%, resulting in a dew point
reading of 70˚F. To ensure the compressors initiate, the
suction pressure will be overridden to 200PSI, if ambient
conditions are above compressor lockout conditions.
Comfort Cooling
Comfort Cooling Test Mode:
This mode is used to test
unit response to a call for space cooling. When activated
the space temperature and humidity will be overridden
to 81.5
˚F
and 15%. To ensure the compressors initiate,
the suction pressure will be overridden to 170PSI, if
ambient conditions are above compressor lockout
conditions.
Heat Test Mode
Heating Test Mode:
This mode is used to test unit
response to a call for space heating. When activated the
space temperature and humidity will be overridden to
58.5
˚F and 15%.
Fan Only Test Mode
Fan Only Test Mode:
This mode is used to test unit
response to no call. When activated, the space
temperature will be set to the cooling setpoint minus the
cooling cut out value and the space humidity will be
overridden to 15%.
