BOOST MODE

BOOST MODE enables the system to operate at a higher com-
pressor speed than rated maximum compressor speed and
satisfy the structural load more effectively during higher
ambient outdoor conditions. BOOST MODE is initiated by
an outdoor temperature sensor located in the outdoor unit.
Please note that outdoor equipment operational sound lev-
els 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**1AB
or later revision. BOOST MODE performance is most effec-
tive when paired with an electronic expansion valve enabled
indoor unit.
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 the BOOST TEMP menu using the following proce-
dure:
1. On the CTK04 HOME screen, select MENU.
2. From the MENU screen, select COMFORTNET™ USER
MENU.
