COOLING EMERGENCY MODE WIRING FOR TXV AP-
PLICABLE INDOOR UNIT
Cooling emergency mode is available when using a TXV
applicable indoor unit. To energize the blower at the appro-
priate speed, standard Legacy wiring is required. The im-
age below shows how the thermostat input terminals are to
be wired when selecting a cooling airflow. Note: the blower
will run continuously with this wiring which is required. The
outdoor unit will cycle as described in the Cooling Emergen-
cy Mode section when appropriate dip switch modes are
set.
