COOLING EMERGENCY MODE WIRING FOR TXV APPLI-
CABLE INDOOR UNIT
Cooling emergency mode is available when using a
TXV applicable indoor unit. To energize the blower
at the appropriate speed, standard Legacy wiring is
required. The image below shows how the thermo-
stat input terminals are to be wired when selecting
a cooling airflow. Note: the blower will run continu-
ously with this wiring which is required. The out-
door unit will cycle as described in the Cooling
Emergency Mode section when appropriate dip
switch modes are set.
