Select the fan setting
Press FAN to select Auto or selectable fan speed.
In “Auto” fan mode the equipment deter-mines the optimal fan speed to meet the set temperature.
When system switch is “Off”, press FAN to circulate air. The fan will run at the user’s selected fan speed.
Note: Selectable fan speed options may vary depending on your equipment.
Select the system setting
Press SYSTEM to select:
- Cool: Remote controller controls only in the cooling mode.
- Heat: Remote controller controls only in the heating mode.
- Drying: Remote controller directs indoor unit to remove moisture out of the air. May result in temperatures below your cool setting
- Auto: Remote controller automatically selects heating or cooling depending on the indoor temperature.
- Off: Indoor unit is off.
Note: Options may vary depending on your equipment.
Multi-zone configurations
In multi-zone configurations, each zone is typically set to the same mode (Cool, Heat, or Drying).
If zones are set to different modes, the first indoor unit to call for heat or cool will take priority. Other zones go into standby, and “Wait” will be displayed on the screen.
Drying mode (if configured)
Drying mode removes moisture from the air and works differently depending on the type of equipment installed. The tem-perature setting might or might not be displayed.
The indoor unit will determine the Drying mode temperature setting. The setting will be either:
- the cool temperature setting, or
- 3°F (2°C) below room temperature.
Commercial program default settings
This remote controller is pre-set to use energy-saving program settings. We recommend these settings, since they can reduce your heating/cooling expenses. (See page 12 to adjust times and temperatures of each time period.)
occupied 2 and unoccupied 2 periods may be programmed as needed, depending on installed configuration.
Residential program default settings
This remote controller is pre-programmed to use commercial energy saving program settings. For use in a home, change the program to match your schedule. (See page 12 to adjust times and temperatures of each time period.)

Permanent hold (residential only)
Press HOLD to permanently adjust the temperature. This will override the temperature settings for all time periods.
The HOLD feature turns off the program schedule and allows you to adjust the temperature manually, as needed.
The system will maintain the set temperature until you manually change it or you press CANCEL to resume the program schedule.
System Changeover
System Changeover is a feature used in climates where both air conditioning and heating are often used on the same day. When the system is set to “Auto,” the remote controller automatically selects heating or cooling depending on the indoor temperature.
Heat and cool settings must be at least 2 degrees apart, depending how your remote controller was configured. The remote controller will automatically adjust settings to maintain this 2
(or more) degree separation.
Note: The “Auto” system setting may not appear, depending on how your remote controller was configured.
Portable Central Controller (optional)
The optional Portable Central Controller can manage temperatures of multiple split-zoning systems from almost anywhere on the property.
The Portable Central Controller also works with other RedLINK™ devices used with other types of heating and cooling equipment.
One Portable Comfort Control can adjust up to 16 zones on a single property.
Note: The remote controller may take up to 15 seconds to respond to commands entered at the Portable Central Controller.
Outdoor air sensor (optional)
The outdoor air sensor allows outdoor air temperature and humidity to be shown on your remote controller.
The outdoor air sensor also works with other RedLINK™ devices used with other types of heating and cooling equipment.
Only use AA lithium batteries for the outdoor air sensor.
Remote Controller additional features
