DESCRIPTION
The Comfort365 thermostat controls heating, cooling and
airflow to the sleeping and living spaces. The thermostat is
installed in the living space, a temperature sensor is
installed in the bedroom space and two modulating
dampers are installed to control the airflow to the living and
sleeping space.
The C365 thermostat monitors the temperature at the
sensor and the temperature at the thermostat every 2
minutes during heating and cooling calls. If the
temperatures are different, the Comfort365 automatically
adjusts the modulating dampers 2% so that more airflow is
directed to the space that needs it for a uniformly
comfortable home.

Nighttime Operation
At night, the C365 thermostat uses the temperature sensor in
the sleeping space to control heating and cooling calls and
directs more airflow to the sleeping space and less airflow to the
unoccupied living space. Energy savings is 30% at night. If
bedrooms are located downstairs, consider turning off the
Nighttime Airflow Control option off.
