Indoor Air Quality (IAQ)
Indoor Air Quality (IAQ) has become an important part of our everyday lives. IAQ affects us in the workplace, schools and more significantly, in our homes. The American Society of Heating, Refrigeration and Air-Conditioning Engineers publishes ASHRAE 62.2, a standard that defines minimum ventilation requirement and acceptable indoor air quality in low-rise residential buildings.
The DFC Digital Fan Control uses smart technology to meet the requirements of ASHRAE 62.2, and is capable of automatically calculating the airflow required to achieve acceptable indoor air quality. It is designed to provide increased ventilation control that is efficient and affordable. Its unique architecture offers a choice of five distinct modes of operation, allowing the control to be programmed to suit a user's preference and lifestyle. The DFC Digital Fan Control provides an excellent way of meeting IAQ needs when combined with an Energy Star qualified AXC-ES In-Line Duct Fan.

Applications
The DFC Digital Fan Control allows the user to choose from five modes of operation.
1. Ventilation Mode
The Ventilation Mode is designed to achieve ASHRAE 62.2 acceptable indoor air quality. In this mode, the fan control operates on a 60 minute cycle, automatically determining the percentage of run time based on floor space, number of rooms and fan capacity. For example, if the fan is On for 15 minutes, it will be Off for 45 minutes.
2. Customized Cycle Mode
The Customized Cycle Mode allows the user to set the On and Off periods for the fan. Once selected, the control will cycle the fan automatically based on the user's preference.
3. Daily On/Off Mode
The Daily On/Off Mode allows the user to program the fan to turn On and Off once a day, at user defined times.
4. Manual Mode
In the Manual Mode, the control operates the fan like a regular on/off switch. Simply pressing the main switch turns the fan On or Off.
5. Countdown Mode
The Countdown Mode allows the fan to operate for any period between 10 and 60 minutes. At the end of the countdown period, fan operation will return to its prior programmed mode.
