Auxiliary Control Settings (cont)

Mode 3—Freeze Sentinel/Heat Sentinel The default settings for Mode 3 are:

Heat Sentinel is off Freeze Sentinel is on.

When Freeze Sentinel is activated, it automatically provides heat without user interface. This helps to prevent plumbing damage by turning the heater and indoor fan ON at 41ºF and OFF at 46ºF.

When Heat Sentinel is activated, it automatically provides cooling without user interface. This helps to prevent an excessively hot room by turning the air conditioner ON at 85ºF and OFF at 80ºF.

NOTE: These functions are active whenever the unit is plugged in, even if the unit is in the STOP position.

Mode 4—Constant ON Fan

The default setting for Mode 4 is OFF.

Mode 5—Temperature Limiting

The default setting for Mode 5 is as follows:

Cool: 0 (60ºF to 85ºF)

Heat: 7 (60ºF to 85ºF)

Temperature limits—Cool

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.

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.

Mode 8—All-Electric Heat (AZ6100 only) The default setting for Mode 8 is OFF.

This electric heat option functions only on the 6100 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 (AZ6100 only) The default setting for Mode 9 is OFF.

When Heat Boost is ON and outer temperatures are between 25ºF and 46ºF, heat pump only operation is locked out. This setting is used to provide supplementary heat to the heat pump operation by electric resistance heat in conditions where the heat pump-only operation is not sufficient to maintain a consistent, comfortable room temperature. NOTE:

Temperature Boost option should not be used with remote thermostat operation. This will cause the unit to switch to resistance heat when the outdoor temperature is 46ºF.
