Honeywell TH8110R1008/U User manual

VisionPRO®Series with RedLINK™
User Guide
TM

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 (TH8321 model)
Your new thermostat also provides:
• Adaptive Intelligent Recovery—over time, the VisionPRO 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.
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.

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.

Using the 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 your thermostat was
installed, the thermostat Home screen
will display humidity readings from only
one sensor. Humidity reading
depends on location
of sensor.
