POSSIBLE PROBLEM
16AI input dip switches are set
improperly.
Incorrect board and point
address.
Incorrect sensor type.
Incorrect board and points
assignment.
Check the Heat and Cool OAT
lockout temps.
SOLUTION
The 16 dip switches on the 16AI
board correspond to each of the
inputs:
Dip Switches Up = Temperature
Sensor
Dip Switches Down = Pressure
Transducer
Set proper board and point set-
tings for both input and output:
Go to the Inputs tab in the appli-
cation's Setup screen and check
Board and Point.
1. Verify that the sensor type in
E2 is the same as the sensor
installed. (For example, "5V-
200PSI" is a 5-volt powered
200PSI pressure transducer, and
"Temperature" is the standard
Retail Solutions temperature
sensor.
NOTE: The previous Eclipse
and Standard sensors are now
5V and 12V respectively.
2. From the Main Menu, select
System Configuration (7) and
Input Definitions (1).
3. Highlight the desired input
and press  (SETUP) to
check Sensor Type.
Make sure that your board and
points are assigned to the correct
compressors and heat stages
From the Home screen, press
 (AHU),  (SETUP).
Move cursor to C5 (HT/CL
