2-4 Sequence of Operation
Analog Inputs Analog Inputs Analog Inputs Analog Inputs
Only Analog Input #1 (AIN1) and Analog Input #6 (Airflow Sensor) have a specific
function that cannot be changed. All other inputs are user configurable in one of the
following modes:
0 Not Used ( Nothing connected to this input )
1 Slide Offset ( Requires Flush Mount Wall Sensor with this Option )
2 Supply Air Temperature
3 Return Air Temperature
4 Mixed Air Temperature
5 Outdoor Air Temperature ( Will broadcast to ALL other controllers )
6 Humidity Sensor ( 4-20 ma scaling )
7 Humidity Sensor ( 0-5 vdc scaling )
8 CO² Sensor ( 4-20 ma scaling )
9 CO² Sensor ( 0-5 vdc scaling )
10 Relief Pressure Sensor ( Requires 0-5 vdc ±0.3” WG Sensor )
11 Dirty Filter Contact ( Normally Open )
12 Alarm Contact ( Normally Open )
13 Alarm Contact ( Normally Closed )

Fan Status Contact ( Normally Open )
Later in this manual, when it discusses the available options, it will be assumed that you
have installed and configured the correct sensors required for the options you select. If
you haven’t then improper operation will occur.
NOTE: All temperature sensors must be Thermister Type III
which provide 77
°
F @ 10K Ohms Resistance.
There are a total of 5 programmable Analog Inputs ( AIN2 - AIN5 and AIN7 ).
Analog Input #1 is always configured for a Space Temperature Sensor. This is also the
input that a push-button override would be connected to since the button press
temporarily shorts the thermister sensor to ground to indicate the override request.
Analog Input #6 ( Airflow Sensor ) can be used for status only or to verify fan operation.
No other control outputs can utilize this sensor.
