NOTE: Not more than 0.5 lb. (8 Oz.) of refrigerant
must be added to the system in order to achieve
the target subcooling. It is recommended to add 4
oz. refrigerant each time and try adjusting the TXV
and let the system stabilize.
*1. 10 ° F ± 1 ° F only for DZ9VCA6010A*.

It is recommended to set the outdoor temperature lockouts
during the initial thermostat set up. Heat pump (compressor)
lockout temperature will enable the compressor to be turned
o and switch heating source from refrigeration to auxiliary/
secondary heating under low outdoor ambient conditions.
Auxiliary (backup) heat lockout temperature will enable aux-
iliary/secondary heating to be turned on when outdoor tem-
perature is much higher than indoor temperature, compressor
might stop operating under this circumstance.

BOOST MODE enables the system to operate at increased
compressor speed to satisfy unusual high loads. BOOST
MODE is initiated by an outdoor temperature sensor
located in the outdoor unit. Please note that outdoor
equipment operational sound levels may increase while
the equipment is running in BOOST MODE. Disabling
BOOST MODE will provide the quietest and most ecient
operation.
NOTE: BOOST MODE performance is most eective when
paired with an electronic expansion valve enabled indoor unit.
NOTE: BOOST MODE is ON by default and is activated when
the outdoor temperature reaches 105°F. BOOST MODE can
be disabled and enabled and the activation temperature
adjusted.
The thermostat reads the indoor humidity level and allows
the user to set a dehumidication target based on these
settings. The thermostat controls the humidity level of the
conditioned space using the cooling system. Dehumidica-
tion 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 cooling the evaporator coil
and ultimately removing more humidity from the structure
than if only in cooling mode. The thermostat also allows for
an additional overcooling limit setting from 0°F to 3°F setup.
This allows the cooling system to further reduce humidity
by lowering the temperature up to 3°F below the cooling
setpoint in an attempt to better achieve desired humidity
levels.
