Startup
The AFA1000/E must be field-calibrated once the
room air supply and exhaust is proportionally
balanced. When the unit is powered up, the
following sequence of events occurs:
1. The alarm performs a self-test of its
functions, LEDs and audible alarm
(approximately 3 seconds).
2. At the end of the delay, the unit will do
one of two things:
a. If the controller has been calibrated, the
unit enters normal operating mode (displays
airflow velocity, LED’s and audible alarm
enabled).
b. If the controller has not been calibrated,
the unit will display “ Requires set up, press
Enter to continue”.

Calibration
1. Press Enter from the “Requires set up” screen or if the controller
is in the Run screen Press and Hold the Enter button for 5 seconds
until the Main Menu is displayed.
2. Using the + / - buttons select SET UP, then select CONFIGURE, then
enter the password (the factory default password is 0-0-0-0), press
Enter to continue.
3. Using the + / - buttons select ECON CONFIGURE, then select
MANUAL / AUTO and press Enter, select MANUAL and press
Enter to continue.
4. Open the sash to the normal operating height and measure the
face velocity using a calibrated instrument. Using the + / - buttons
adjust the Manual output so that the face velocity is equal to the
design velocity, e.g. 0.50m/sec (100fpm) , then press Enter, then
select DONE and press Enter again.
5. Using the + / - buttons select SET UP, then select CALIBRATION,
then enter the password (the factory default password is 0-0-0-0),
press Enter to continue.
6. With the sash open to the normal operating height again measure
the face velocity using a calibrated instrument. Using the + /
-buttons enter the measured face velocity then press Enter, the
controller will then sample the airflow for 5 seconds.
7. If the airflow sample is unstable the controller will display
“Deviations too High”, follow the instructions to repeat the
sample or quit the calibration.
