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)
