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. A Portable Comfort Control can
control up to 16 thermostats.
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 will
respond to temperature and humidity readings at the sensor
location—providing comfort where the sensor is located. With
multiple sensors, the thermostat can average temperature
readings from each, to optimize comfort throughout your home.
The thermostat can be used with up to 6 Wireless Indoor Sensors.
REDLINK™ INTERNET GATEWAY
The Honeywell RedLINK Internet Gateway gives you remote
access to your Prestige
®
thermostat from the web, smart phone or
tablet. You can view 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 device mounts beside your door for one-touch control. Press
AWAY to control to an energy saving temperature when you leave
home. Press HOME to control to a comfortable temperature when
you return. 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. The
Residential cover is labeled HOME, AWAY and VACATION and
the Commercial cover is labeled OCCUPIED, UNOCCUPIED and
HOLIDAY. The thermostat can be used 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 for increased ventilation. The thermostat can
be used with up to 6 Vent Boost remotes.
