Field Selectable Boost Mode
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 efficient operation.
NOTE: Boost mode is applicable only for
*VZC200**1AB and GVZC20**AA or later revision.
BOOST MODE performance is most effective 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
adjusted in the BOOST TEMP menu using the following
procedure:
1. On the CTK04 HOME screen, select MENU.
2. From the MENU screen, select COMFORTNET™
USER MENU.
3. Enter Installer password. (The password is the Date
Code located on the thermostat and is available by
entering the EQUIPMENT STATUS menu and scrolling
to the bottom).
