Menu: Vacation scheduling (residential use)
This feature lets you conserve energy while away, and restores a comfortable temperature just before you return to your home. Press s or t at each screen to enter temperatures, dates and times as prompted, then press DONE. The temperature you set will be maintained until you return, then the program schedule will resume.
Menu: Holiday/event scheduling (commercial use)
This feature lets you conserve energy when the workplace is unoccupied for special events or on holidays. The US (United States) and CANADIAN options allow you to select from a list of holidays commonly observed in each country. You can set the system to “unoccupied” or “occupied” mode for the days you select. The CUSTOM EVENTS button gives you more options to customize temperatures for specific dates and times in the future
Menu: Holiday override (commercial use)
Press HOLIDAY MODE to set temperatures that will be maintained from now until the date you expect to return. The thermostat will resume the normal schedule on the date you set. You can press CANCEL at any time to resume the normal schedule.
Initiate Occupancy mode (commercial use)
This feature keeps temperature at an energy-saving level until the PRESS TO START OCCUPANCY button is pressed. When you arrive, press the button to maintain a comfortable temperature while the room is occupied. Press the s or t buttons to set the temperature or “Hold Until” time. The temperature is maintained until the time you set. Temperature returns to an energy- saving level after the timer expires, or the “Occupied” period ends. The thermostat keeps temperature at an energy saving level until OVERRIDE or PRESS TO START OCCUPANCY button is pressed.
Remote setback (commercial use)
During occupied periods, an occupancy sensor tells the thermostat to go to STANDBY (setback settings) when no one is in the room. If someone is in the room, then it follows the settings of the occupied period. The occupancy sensor is ignored during unoccupied periods. If the thermostat is setup for non-programmable, the sensor tells the thermostat to go to STANDBY settings when no one is in the room. If someone is in the room, then it follows the settings set by the user. Depending on how your thermostat was installed, there may be a time delay of up to 30 minutes before it switches from occupied settings to the standby settings. This allows the room to stay comfortable if the room is unoccupied for a short period of time.

Advanced features
Adaptive Intelligent Recovery (residential use only)
Over time, the Prestige® thermostat “learns” how long it takes your system to provide the temperature you want. It turns on the heating or cooling system earlier to make sure you’re comfortable at the time you expect.
Dehumidification Away Mode
Your system can be set to control indoor climate while your home is vacant during the humid season. Before you leave, press MENU, then select DEHUMIDIFICATION AWAY MODE. Temperature and humidity will be kept at levels adequate to protect your home and possessions while you are away. When you return, press CANCEL to resume normal operation.
Compressor Protection
This feature protects your air-conditioning system by forcing the compressor to pause before restarting, to prevent damage. During this brief pause, the message “Waiting for Equipment” is displayed on screen.
Pre-occupancy Purge (commercial use only)
This feature turns on the fan 1 to 3 hours before each “occupied” time period, to provide a comfortable work environment when you arrive.
Menu: Installer options
- These options should be changed only by professionally qualified technicians.
- To avoid disabling or damaging your equipment, do not change these options yourself.
- The USB port on the bottom of the thermostat is for use by professional installers only. Do not attempt to use this port yourself.
Battery replacement: Wireless outdoor sensor
Replace batteries in your outdoor sensor when a warning appears on the thermostat screen, about two months before batteries are depleted. After new batteries are installed, the outdoor sensor will restore communication with the wireless network within a few seconds
Battery replacement: Wireless indoor sensor
Replace batteries in your indoor sensor when a warning appears on the thermostat screen, about two months before batteries are depleted. When the sensor status light begins flashing red, battery power is critically low and will be depleted within 2–3 weeks. During normal operation, the status light remains off
Humidity display
In some circumstances, the humidity displayed on the Home screen may not match humidity near the thermostat. Some systems are set up to use two sensors, one to control humidification, the other for dehumidification. These sensors are often installed in different locations. Depending on how it was configured when installed, the thermostat will only display humidity readings from one sensor on the Home screen.
Optional accessories
Portable Comfort Control
If you have only one thermostat, you move this remote control from room to room (like a portable thermostat), to make sure the temperature is comfortable in the room you’re using. If you have multiple thermostats, you can view and adjust the temperature in each room from your armchair.
Wireless Outdoor Sensor
With a wireless outdoor sensor, your Prestige® thermostat can display outside temperature and humidity. This information can also be displayed on your handheld Portable Comfort Control.
Wireless Indoor Sensor
If an indoor sensor is installed, your Prestige® thermostat can monitor the temperature and humidity at that location and adjust the system to maintain comfort there. With multiple sensors, the thermostat can average temperature readings from each, to optimize comfort throughout your home.
RedLINK™ Internet Gateway
The Honeywell RedLINK Internet Gateway gives you remote access to your Prestige® thermostat via the Internet or from your smart phone. You can use a Web browser to review or adjust indoor temperature, system mode and other settings. The Gateway can also send alerts to as many as 6 email addresses to notify you if a problem occurs.
Wireless Entry/Exit Remote
This handy device mounts beside your door for convenient one-touch control. Press AWAY when you leave, and HOME when you return, to keep your home comfortable while occupied and save energy when you’re away. To change pre-set temperatures, go to MENU > ENTRY/EXIT REMOTE SETTINGS.
