Since identical I/O Boxes are used with both AERCO gas-fired boilers and water heaters, some
of the input and output connections apply only to boilers while others are common to both
boilers and heaters. These I/O Box connections are noted in the sections below.
NOTE
Use Figure 2-12 to determine the functions of the I/O PCB connections. Do
not use the silkscreened labels on the PCB itself, as these may not match.
DO NOT make any connections to the I/O Box terminals labeled “NOT
USED”. Attempting to do so may cause equipment damage.
