Heat Pump with Outdoor Temperature Lockouts
It is recommended to set the outdoor temperature lockouts
during the initial thermostat set up. This will enable the
compressor to be turned off and switch heating source
from refrigeration to auxiliary/secondary heating under low
ambient conditions.

Inverter units are accessed the compressor lockout by any
of the following methods:
• setting the “Cbp” menu (Compressor lockout
temperature) to through the indoor unit control board
push buttons
• Through the CoolCloud HVAC phone application
If installing with a CTK04 thermostat, please see the
addendum for further instructions.
Field Selectable Boost Mode
BOOST MODE can be enabled or disabled through the
control board push buttons or through the CoolCloud app.
BOOST MODE allows the system to operate at increased
compressor speed to satisfy unusually 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 efficient operation.
NOTE: BOOST MODE is applicable only for
AVZC200**AB and GVZC20**AA or later revision.
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 in the Settings menu of the CoolCloud app or
through the indoor / outdoor push button menus.
If installing with a CTK04 thermostat, please see the
addendum for further instructions.
Dehumidification
NOTE: For regions with high humidity, it is
strongly recommend to use a thermostat with
humidity sensor and dehumidification terminal.
Without this type of thermostat, dehumidification
operation does not work.
Dehumidification requires a thermostat capable of reading
the indoor humidity level and allowing the user to set a
dehumidification target.
The thermostat controls the humidity level of
the conditioned space using the cooling system.
Dehumidification is engaged whenever a cooling demand
is present and 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 may also allow for an additional
overcooling limit setting depending on the thermostat
utilized. This allows the cooling system to further reduce
humidity by lowering the temperature below the cooling
setpoint in an attempt to better achieve desired humidity
levels.
Dehumidification Tips
For effective dehumidification operation:
• Ensure “Dehumidification selection” is NOT set to
“OFF”.
• Verify the cooling airflow profile is set to “Profile D”.
- See the Cool Set-up section of the Installation Manual for
complete airflow profile details.
- By default, “Dehumidification selection” is standard and
the cooling airflow profile 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.
• In addition, the system can have Enhanced
Dehumidification operation in setting “A”, “B”,
or “C” of “Dehumidification Selection” based on
dehumidification demand.
- See the DEHUMIDIFICATION SELECT section of the
Installation Manual for more detail.
COMFORTBRIDGE™ SYSTEM
Overview
The ComfortBridge based inverter heating and air
conditioning system uses an indoor unit and outdoor unit
digitally communicating with one another via a two-way
communications path. ComfortBridge is compatible with
any 24 VAC single stage thermostat which send inputs to
the indoor unit.
Comfortbridge System Advanced Features
The ComfortBridge system permits access to system
information, advanced set-up features, and advanced
diagnostic/troubleshooting features via the control board
push buttons or the CoolCloud HVAC app.
