To disable airflow control so the thermostat operates
as a typical thermostat, use Option 17 to turn airflow
control off. The thermostat will control the system as
any other thermostat and the nighttime airflow option
will be disabled.
i
The C365 thermostat controls heating, cooling and airflow to
the upstairs and downstairs using an upstairs and a downstairs
modulating damper. A temperature sensor located upstairs
monitors the upstairs temperature and the temperature sensor
in the C365 monitors the downstairs temperature.
The C365 adjusts the upstairs and downstairs airflow during
heating and cooling calls to maintain uniform upstairs and
downstairs temperatures.

AIRFLOW CONTROL Airflow can be turned off using Option
15. Dampers fully open, nighttime airflow options are disabled
and airflow is no longer displayed on the thermostat.
AIRFLOW LIMITS Maximum upstairs and downstairs, heating
and cooling airflow limits can be set during installation.
NIGHTTIME OPERATION The C365 thermostat uses the
upstairs temperature sensor to control heating and cooling
calls and directs more airflow upstairs. If bedrooms are located
downstairs, the Nighttime Airflow option should be turned 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.
UPSTAIRS TEMPERATURE SENSOR One TS510W sensor
or two TS520W upstairs temperature sensors can be used.
MODULATING DAMPERS Round or rectangular dampers
using the A80MT actuator and up to 1 inch static pressure.
POWER Operates on 24VAC from the HVAC equipment using
the R and C wires.

Description

SEPARATE THE C365 SUBBASE
ATTACH THE SUBBASE TO THE WALL
INSTALL TWO AA BATTERIES
Place a slotted screwdiriver in the slots as shown and rotate to
remove subbase from the C365 housing.
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 upstairs
temperature sensor pass through the opening between the
terminals.
The batteries power the clock when 24VAC power is lost. Slide
the battery cover downward and install the two AA batteries as
shown.
Install an R80CT damper in the duct supplying air to the upstairs
and wire the terminals to the corresponding terminals on the
C365T. Install a second R80CT damper in the duct supplying air
to the downstairs and wire it to the C365T. Each damper uses
2.4VA of power.
When two or more dampers are required to define the upstairs or
downstairs zones, the damper may be wired in parallel. LEDS
on the damper actuator indicate when the damper is fully open
(green) or fully closed (red).

WIRING INSTRUCTIONS (Cont)
Use 3-conductor, 18 or 20 gage, thermostat cable to wire from
the C365 Thermostat to the upstairs and downstairs dampers.
There are separate terminals for the upstairs and the
downstairs dampers.
Multiple dampers can be used to construct the upstairs or
downstairs zones. Daisy chain terminals– COM to COM, OPN
to OPN and CLS to CLS.
Use 2-conductor, 18 or 20 gage, thermostat cable to wire from
the C365 Thermostat to the upstairs temperature sensor.
For single temperature sensor application, use Model TS5-10.
Two temperature sensors can be installed in different areas
upstairs and the two temperatures will be averaged. For dual
sensor applications, use Model TS5-20 and daisy chain the
sensors.
