Figure 2-13: Input/Output (I/O) Box – Front View, Box Cover Removed
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 2-14 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.
--WARNING! -
DO NOT make any connections to the I/O Box terminals labeled
“NOT USED”. Attempting to do so may cause equipment
damage.
