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.
