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 tempera-
ture 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 ComfortNetTM CTK03 communi-
cating 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 ComfortNetTM CTK03 commu-
nicating 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.
