The EvenAir WiFi thermostat controls heating, cooling and AIRFLOW to the sleeping and living
areas in a home and provides remote access to your HVAC system using a smart phone, tablet or
PC. The thermostat is installed in the downstairs living area, a temperature sensor is installed in the
upstairs bedroom area and two modulating dampers are installed to control the airflow to the
living and sleeping area.
The EvenAir 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
EvenAir thermostat automatically adjusts the modulating dampers 2% so that more airflow is
directed to the space that needs it for a uniformly comfortable home.
COMPONENTS:
EvenAir T21WF Thermostat
EvenAir TS51 or TS52 Wired Temperature Sensor(s) (sold separately)
EvenAir AMT Type Motorized Damper, With Terminals (sold separately)

DISPLAYING THE LIVING AND BEDROOM AREA TEMPERATURE
The living area temperature is normally displayed. The bedroom area temperature can be displayed by touching
Living on the touchscreen. The temperature will change to the bedroom space temperature, indicated by Sleeping.
Touch Sleeping to return to displaying the Living area temperature.
NIGHTTIME AIRFLOW CONTROL
The Nighttime Airflow Control option is an energy saving feature where the thermostat uses the temperature sensor
in the bedroom area to control heating and cooling calls and directs more airflow to the bedroom at night
and less airflow to the unoccupied living . Nighttime Airflow Control begins at 10:00pm but can be changed
by accessing the schedule in the User Options. The airflow to the bedroom space defaults to 130% but can be
adjusted for both heating and cooling in the User Options. Nighttime Airflow Control is defaulted to On but can be
turned Off in the User Options. The homeowner should consider turning this option off if bedrooms are located on
the same floor as the living area and using the same airflow trunk as the living area.
AUTOMATIC OR MANUAL AIRFLOW CONTROL
Automatic Airflow Control is the thermostat default and is typically used by homeowners to maintain uniform
comfort throughout the home. However, homeowners with unusual work schedules, home offices, etc. may want to
use the manual airflow control feature. This features allows the homeowner to change the airflow level as desired
and hold that level indefinitely. This feature needs to be enabled using Installer Option 18. The homeowner then
needs to turn automatic airflow control off using the User Options. The Nighttime Airflow Control option is still
enabled but can be turned off, if desired, using the User Options.
AIRFLOW OVERRIDE
On occasion, homeowners may want to direct more airflow to an area. For example, during a party, more airflow
may be desired in the living area. The homeowner sets the airflow level to the area and the thermostat will hold
the airflow for 3 hours. After 3 hours, the thermostat returns to automatic airflow control.
area
area
AIRFLOW CONTROL TURNED OFF
In some installations, the EvenAir thermostat has been installed to control the system only. The thermostat operates
just like any other thermostat. The airflow control options are disabled and airflow is no longer displayed on the
thermostat.
WiFi REMOTE ACCESS
The EvenAir WiFi thermostat connects to the home’s WiFi network and provides remote access, via the internet, to your
home’s heating and cooling system from anywhere using a smart phone, tablet or PC.

all power to your HVAC system.
Read and follow all instructions carefully.
Read entire manual before installing EvenAir products.
Follow all local electrical codes during installation. All
wiring must conform to local and national electrical
codes.
Use cautions when mounting components to surfaces
that may have concealed wiring beneath the surface.
When servicing EvenAir system or accessing products,
turn off all power to these items.
ATTENTION INSTALLER
1)
Install and wire components to the thermostat.
(see Wiring section)
2)
Place the thermostat on the subbase. Do not install
batteries.
3)
Turn power to the HVAC equipment On.
4)
Check for Error Messages. (see Error Message section)
5)
Set equipment options 1-5 if different than factory
default settings. (see Installer Options section).
6)
Test the installation using the Installer Test Menu.
(see Installer Test Menu section on page 13)
7)
Install batteries and set the time and day (see Installing
Batteries and Set Time and Day section)
REMOVE SUBBASE
Place a slotted screwdriver in the
slots as shown and rotate to
remove subbase from the
thermostat housing.

INSTALL DAMPERS
Install a damper with an AMT actuator in the duct supplying air
to the sleeping area and wire the terminals to the
corresponding terminals on the T21. Install a second damper
with an AMT actuator in the duct supplying air to the living area
and wire it to the T21. Each damper uses 2.4VA of power.
Ensure that damper installation does not cause obstruction
!
to the damper blade.
When two or more dampers are required to define the sleeping
or living area, the damper may be wired in parallel. LEDs on
the damper actuator indicate when the damper is fully open
(green) or fully closed (red). When properly installed, the
dampers will never fully close.

MAINTENANCE AND TROUBLESHOOTING
DAMPER OPERATION
Problem - No airflow to the sleeping area AND living
area registers
Turn system off immediately. Both dampers may be wired
backwards at the subbase or at the damper actuator (closing
rather than opening).
Problem - No airflow to the sleeping area OR living
area registers
Turn system off. One of the dampers may be wired backwards
at the subbase or at the damper actuator (closing rather
than opening).
Problem - When directing airflow to the sleeping area, the
airflow is actually directed to the living area, and when
directing the airflow to the living area, the airflow is actually
directed to the sleeping area.
Turn system off. Check if the dampers are switched (sleeping
area damper is wired to the living area terminals and the
living area damper is wired to the sleeping area terminals.)
COMFORT CONCERNS
Problem - Downstairs bedroom is too cold or too hot at night.
The Nighttime Airflow Control option directs more airflow to the
sleeping area and less airflow to the unoccupied living area. If
the downstairs bedroom is on the same HVAC trunk as the
living area, the downstairs bedroom may become uncomfortable
at night. Turn off the Nighttime Airflow Control option using the
User Options.
SENSOR INSTALLATION
Problem - nS message on thermostat.
Check that the sensor is wired correctly. Check for a short in
the sensor wiring.
Problem - Sleeping area temperature reading very high or
very low.
Check that the correct sensor(s) have been used. One TS51
sensor is used in a single sensor installation. Two TS52
sensors are used in a dual sensor installation.
Problem - The room temperature on the thermostat seems
too high or too low.
The thermostat is factory calibrated within 1 degree.
However, if a homeowner finds the temperature “feels”
too high or too low, the thermostat can be calibrated to
what the homeowner feels is the correct temperature using
Installer option 13 for the living area and option 14 for
the sleeping area.
