Field Selectable Boost Mode
BOOST MODE enables the system to operate at increased
compressor speeds to satisfy unusual high loads. BOOST
MODE is initiated by an outdoor temperature sensor locat-
ed 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 performance is most effective 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 ad-
justed in BOOST TEMP menu using the following procedure:
1. On the HOME screen, select MENU.
2. From the MENU screen, select COMFORTNET™
USER MENU.
