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
AVXC200**1AB 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.
