Touch Screen Thermostat

User Guide

Welcome

Congratulations on your purchase of a Honeywell touch screen programmable thermostat. When used with the optional RedLINK Internet Gateway, you can remotely monitor and control the heating and cooling system in your home or business—you can stay connected to your comfort system wherever you go.

Honeywell’s Total Connect Comfort is the perfect solution if you travel frequently, own a vacation home, a business or manage an investment property or if you are simply looking for peace of mind.

Features of your Prestige thermostat

With your new thermostat, you can:

 Connect to the internet to monitor and control your heating/cooling system

and receive alerts by email (requires optional RedLINK Internet Gateway)

 View outdoor temperature and humidity (requires optional Wireless

Outdoor Sensor)

 Control humidification, dehumidifcation or ventilation

Your new thermostat also provides:

 Adaptive Intelligent Recovery—over time, the Prestige thermostat “learns”

how long it takes your system to reach the temperature you want. It turns on the heating or cooling system earlier to make sure you’re comfortable at the time you expect.

 Dealer information on the screen—making it easy for you to contact your

dealer for service.

 Vacation and holiday scheduling—allowing you to program a setback

temperature to save energy while you are away.

 Keypad lockout to prevent unauthorized changes.  Equipment status—provides on/off status of all equipment controlled by

the thermostat.

 Preferences—allowing you to customize the thermostat to your desired

settings.

Remote setback (commercial use)

During Occupied program periods, an occupancy sensor directs the thermostat to go to REMOTE SETBACK settings when the room is empty. If someone is in the room, it uses the Occupied program period settings. The thermostat ignores the occupancy sensor during Unoccupied program periods.

If the thermostat is set up to be non-programmable, the sensor directs the thermostat to go to REMOTE SETBACK settings when the room is empty. If someone is in the room, then it follows the settings set by the user.

Depending on how your thermostat was installed, it may delay for up to 30 minutes before switching to REMOTE SETBACK settings. This delay allows the room to stay comfortable if the room is unoccupied for only a short time.
