AIRFLOW CONTROL Airflow control can be turned off using
Option 17. The thermostat will operate as a typical thermostat.
AIRFLOW LIMITS Maximum airflow limits in heating and
cooling can be set during installation.
NIGHTTIME OPERATION The C365 thermostat uses the
temperature sensor to control heating and cooling calls and
directs more airflow to the sleeping area. If bedrooms are
located downstairs, consider turning off the Nighttime Airflow
Control option off.
COMPATIBLE EQUIPMENT Gas/electric equipment with 2-
stage heating and 1-stage cooling or 1-stage heating and 2-
stage cooling and heat pumps with 2-stage heating and 2-
stage cooling.
TEMPERATURE SENSOR One TS510W sensor or two
TS520W temperature sensors can be used in the sleeping
area.
MODULATING DAMPERS Round or rectangular dampers

Comfort
The Comfort365 thermostat controls heating, cooling and airflow to
the sleeping and living areas. The thermostat is installed in the living
area, a temperature sensor is installed in the bedroom area 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.
The energy saving nighttime airflow control option uses the
temperature sensor in the sleeping space to control heating and
cooling calls and directs more airflow to the upstairs sleeping space
while decreasing the airflow to unoccupied living space.
The user can manually adjust airflow on occasions when more airflow
is needed in the bedroom space or living space.

User Airflow Control enables the user to control the
airflow rather than the thermostat automatically
controlling the airflow. Installer must enable Option 18
and the user must turn off automatic airflow in the
User Options. The Nighttime Airflow Control is still
enabled, but can be turned off using User Options.
Disabling Airflow Control Turn Airflow Control Off
using Option 17. The thermostat will control the system
just like any other thermostat. Dampers fully open,
nighttime airflow options are disabled and airflow is no
longer displayed on the thermostat
i

SEPARATE THE C365 SUBBASE
Place a slotted screwdiriver in the slots as shown and rotate to
remove subbase from the C365 housing.
!Turn off all power to the HVAC system before wiring or installing Comfort365 components.
READ THESE INSTRUCTIONS CAREFULLY
AND COMPLETELY BEFORE PROCEEDING WITH INSTALLATION.
ATTACH THE SUBBASE TO THE WALL
Attach the subbase to an interior wall and about 5-feet above
the floor as shown using the screws and wall anchors supplied.
The wires to the dampers, HVAC equipment and the
temperature sensor pass through the opening between the
terminals.

INSTALL TWO AA BATTERIES
The batteries power the clock

Slide the battery cover
downward and install the two
AA batteries as shown.
Install an R80CT damper in the duct supplying air to the
sleeping area and wire the terminals to the corresponding
terminals on the C365T21. Install a second R80CT damper in
the duct supplying air to the living area and wire it to the
C365T21. Each damper uses 2.4VA of power.
When two or more dampers are required to define the sleeping
or living area, the dampers may be wired in parallel. LEDS on
the damper actuator indicate when the damper is fully open
(green) or fully closed (red).
INSTALL SLEEPING AND LIVING AREA DAMPERS
Ensure that damper installation does not cause
obstruction to the damper blade.
