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. Two covers are sold with the
device that allow it to be used in residential or commercial
applications. Residential cover uses HOME, AWAY and
VACATION and the Commercial cover uses OCCUPIED,
UNOCCUPIED and HOLIDAY. The thermostat can work with up to
3 Entry/Exit remotes. Each Entry/Exit remote can control up to 16
thermostats.
WIRELESS VENT AND FILTER BOOST REMOTE
This handy device mounts anywhere in your home (typically
bathroom or kitchen) for convenient on demand ventilation. Select
20, 40 or 60 minutes as desired for increased ventilation. The
thermostat can work with up to 6 Vent Boost remotes.
