Apply 24VAC to the dampers and set them as the Upstairs
or Downstairs damper.
Wire the 24VAC terminals on the dampers to R and C at
the equipment.
Remove the existing thermostat and install the C365
subbase.
Using the existing thermostat cable connect the subbase
to the equipment.
Install two AA batteries in the C365 thermostat.
Install one or two upstairs temperature sensors.
Set the sensor as #1 or #2
Use the Comfort365 to select equipment and options.
When two or more wireless Comfort365 systems are
installed within 300-feet of each other, different home
addresses can be used to prevent adjacent systems from
interfering with each other.
The small pushbutton switch on the damper actuator is used to
set the wireless damper actuator as the Upstairs or Downstairs
damper. With 24VAC power applied to the actuator, press and
hold the switch until the green LED blinks once or twice.
Release the switch after one blink to set the damper as the
downstairs damper or release the switch after two blinks to set
the damper as the upstairs damper. If more than one damper is
required to define the upstairs or downstairs area, follow the
above instructions to set the additional dampers as Upstairs or
Downstairs dampers.

4) Wiring C365 Subbase
The subbase is connected to the equipment using the existing
thermostat cable or a new cable if the replacement equipment
requires more wires.
Warning!
Turn the power to the HVAC equipment off before wiring.
