Airflow Control
Airflow control can be turned off using Option 17. The
thermostat will operate as a typical thermostat.
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.
Wired Sleeping Area Temperature Sensors
One TS510W sensor or two TS520W sensors can be used in the
sleeping space and wire to the thermostat.
Modulating Dampers
Round or rectangular dampers using the A80MT wired actuator
and up to 1 inch static pressure.
Power
Operates on 24VAC from the HVAC equipment using the R and
C wires.
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.
Remotely access the home’s HVAC system from anywhere using
a smart phone, tablet or PC.
Remote Access
FEATURES
Airflow Limits
Maximum airflow limits in heating and cooling can be set
during installation.
Manual Airflow Control
Manual airflow control enables the homeowner to direct more
airflow to the living or sleeping space as they desire. This option
is ideal for homeowners who have an unusual work schedule,
home office or spend more time in one space than the other.

This manual is separated into two different sections: one for the Homeowner and one for the Installer.
CAUTIONS
Use cautions when mounting components to surfaces
that may have concealed wiring beneath the surface.
!
INSTALLATION
Before installing the Comfort365 system, turn off
all power to your HVAC system.
Read and follow all instructions carefully.
Follow all local electrical codes during installation. All
wiring must conform to local and national electrical
codes.
i
ATTENTION INSTALLER (cont.)

When servicing Comfort365 system or accessing
products, turn off all power to these items.
Nighttime Airflow Control is defaulted to ON. If
bedrooms are located downstairs, consider turning this
option Off using the User Options if bedrooms are not
on the same trunk.
Airflow Control Off Option 17 turns off Airflow Control.
The thermostat controls the system, dampers fully open,
nighttime airflow control is disabled and airflow is no
longer displayed on the thermostat.
User Airflow Control can be enabled using the User
Options.
Install batteries and set the time and day (see Installing
Batteries and Set Time and Day section)
9)
Test the damper operation and airflow by initiating a
cooling call and overriding automatic airflow. Touch
the area where Airflow % is displayed. The set point
temperature will disappear. Use the UP key to direct
150% airflow to the sleeping space. You should feel
more airflow in the sleeping space compared to the
living space. The LED on the sleeping space damper
should be green (open) and the LED on the living
space damper should be off (partially closed).

The thermostat automatically controls airflow to the living and
sleeping space. However, the thermostat includes options to
allow the homeowner to direct more airflow to either the living
space or the sleeping space.
Override Airflow for 3 Hours
Touch the Airflow % area. The set point disappears. Use the UP
key to increase airflow to the sleeping space or the DOWN key
to increase airflow to the living space. To end airflow override,
touch the Airflow % area, then touch the MODE key.
Override Airflow Permanently (Manual Control)
Touch the MENU key twice to display the AAC option. This
option, Automatic Airflow Control, defaults to On. Turn OFF by
touching the DOWN key. Manually change the airflow by
touching the Airflow % area and using the UP or DOWN key to
direct airflow to the living or sleeping space. The airflow % will
remain until the homeowner makes an adjustment.
Note: If Nighttime Airflow Control is On, at the morning start
time when Nighttime Airflow Control ends, the airflow % will
change to 100%. This prompts the homeowner to evaluate the
airflow needs for that day.
How do I direct more airflow to the downstairs
living space or upstairs bedroom space.
HELPFUL HINTS FOR HOMEOWNERS
Many homeowners run their thermostat in the HOLD mode. Set
the HOLD mode by touching the MODE key until HOLD is
displayed. Now select the SYSTEM mode and adjust your set
point. In COOL the thermostat will turn on cooling when the
room temperature is at or above the set point temperature. In
HEAT the thermostat will turn on heating when the room
temperature is at or below the set point temperature.
If your household follows a set schedule, the SCHEDULE mode
can be selecting by touching the MODE key until SCHEDULE is
displayed. The thermostat will now follow the default schedule
or a custom schedule set by the homeowner.
What are common settings for my thermostat?
Touch the area where Living and the room temperature is
displayed. The thermostat will now display the sleeping space
temperature. Touch the area again to display the living space
temperature.
If the sleeping space temperature is unusually low or high,
contact your installer. The wrong type of sensors may have been
installed or the sensors may have been wired incorrectly.
Note: If Nighttime Airflow Control option is On, the thermostat
will automatically display the sleeping temperature at the Night
start time.
How do I display the sleeping space
temperature?
One of the biggest energy saving features is the Nighttime
Airflow Control option which can save 30% in energy at night.
This option is defaulted to On and is ideal when all of the
bedrooms are located upstairs. This option uses the
temperature sensors in the sleeping area to make heating and
cooling calls. In addition, the thermostat automatically directs
130% more airflow to the sleeping space and 30% less airflow
to the unoccupied living space.
Does the Comfort365 have any energy saving
features?
Test the airflow by overriding the airflow (See above). Increase
the airflow to the sleeping space to the maximum. You should
feel more airflow coming from the registers in the sleeping
space compared to the registers in the living space. Now
increase the airflow to the living space to the maximum. You
should feel more airflow coming from the registers in the living
space compared to the registers in the sleeping space.
If you do not get these results, contact your installer.
My airflow doesn’t seem to be working properly.
