Mode 4—Constant ON fan
The default setting for Mode 4 is OFF.
NOTE: Constant fan “on” runs the indoor fan continuously
at high speed—even if the unit is turned off.
Mode 5—Temperature limiting
The default setting for Mode 5 is as follows:
Cool: 2 (66ºF to 85ºF) Heat: 5 (60ºF to 78ºF)
Temperature limits—Cool Temperature limits—Heat
0 = 60°F to 85°F 0 = 60°F to 65°F
1 = 64°F to 85°F 1 = 60°F to 70°F
2 = 66°F to 85°F 2 = 60°F to 72°F
3 = 68°F to 85°F 3 = 60°F to 74°F
4 = 70°F to 85°F 4 = 60°F to 76°F
5 = 72°F to 85°F 5 = 60°F to 78°F
6 = 74°F to 85°F 6 = 60°F to 80°F
7 = 76°F to 85°F 7 = 60°F to 85°F
Mode 6—Remote thermostat – Class 2
The default setting for Mode 6 is OFF. Setting this mode
to ON will allow the unit to operate with a Class 2 Remote
Control Wall Thermostat. Hitting the + button a second time
will turn on Mode 6A, which is required for auto-changeover
thermostats.
Mode 7—Duct mode
The default setting for Mode 7 is OFF. This setting is used
when the unit is installed using a duct adapter kit. If the
unit is ducted, the Duct Mode needs to be set to ON.
This increases the fan speed to ensure proper circulation.
NOTE: Heater wattages are reduced in duct mode
(see page 39).
NOTE: This function is disabled on Dry Air 25 models.
Mode 8—All-electric heat (AZ65 only)
The default setting for Mode 8 is OFF. This electric heat
option functions only on the AZ65 model. When this option
is ON, heat pump operation is locked out, causing the unit
to provide only electric resistance heat.
Mode 9—Heat boost (AZ65 only)
The default setting for Mode 9 is OFF. The Heat Boost option
works with remote thermostat operation and unit control
operation. This setting is used to provide 1000 watts of
supplementary electric heat to the heat pump operation.
