Start-up
Let's get started on the startup of the unit. The best
way to check the unit out is to follow the
Sequence of
Operations
.
1. All sensor readings should display a good
value. A sensor reading -60.2 or 296 has an
open circuit or is shorted respectively. The
condition on the second line will display
“ALARM/ SENSOR FAIL” or “SAT FAIL’. By
selecting the alarm key (red square with
an exclamation point on top line) the new
screen will display the failed sensor. If there
are no failures navigate to the
Calibration
screen by press the Setup link on the Home
screen. Now press the calibration link to
display the
Calibration
screen. Show all
points. Remember the unit will receive the
OAT/OARH readings from the BAS system.
However, you should check the local OAT/OARH
sensor by navigating to the
Control
screen
and turning on “Lock OAT/OARH sensor ON”.
Return to the
Calibrate
screen and check the
OAT/OARH reading. Turn this option off after
verifying the readings. Correct the sensor
before proceeding. The SF AMS reading will be
checked after the supply fan is running.
