CAUTION
DO NOT make any connections to the I/O Box terminals labeled “NOT USED”.
Attempting to do so may cause equipment damage.
Figure 2-12. I/O Box Terminal Strips
2.12.1 Outdoor Air Sensor
Not Applicable to Water Heaters.
2.12.2 AUX SENSOR IN
The AUX SENSOR IN terminals can be used to add an additional temperature sensor for monitoring
purposes. This input is always enabled and is a view only input that can be seen in the operating menu.
The sensor must be wired to the AUX SENSOR IN and SENSOR COMMON and must be similar to
AERCO BALCO wire sensor P/N 12449. A resistance chart for this sensor is located in APPENDIX C.
2.12.3 ANALOG IN
The ANALOG IN + and – terminals are used when an external signal is used to change the setpoint
(Remote Setpoint Mode) of the heater.
Either a 4 to 20 mA /1 to 5 VDC or a 0 to 20 mA/ 0 to 5 VDC signal may be used to vary the setpoint or
air/fuel valve position. The factory default setting is for 4 to 20 mA / 1 to 5 VDC, however this may be
changed to 0 to 20 mA / 0 to 5 VDC using the Configuration Menu described in Chapter 3.
If voltage rather than current is selected as the drive signal, a DIP switch must be set on the PMC Board
located inside the Control Box. Contact the AERCO factory for information on setting DIP switches.
