DFC DIGITAL FAN CONTROL
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 the minimum ventilation requirement and acceptable indoor air quality in low-rise residential buildings.
The DFC Digital Fan Control uses smart technology
to address the requirements of ASHRAE 62.2, and it 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 affor
dable. 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. When combined with an AXC In-Line Duct Fan, the DFC Digital Fan Control provides
an excellent way of meeting IAQ standards.

MODES OF OPERATION
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, automat-
ically 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
pro-
gram 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 button turns the fan On or Off.
5. Countdown Mode
The Countdown Mode allows the fan to operate for
any period betw
een 10 and 60 minutes. At the end
of the countdown period, fan operation will return
to its prior progra
mmed mode.
