** The THP9045A1098 C-wire adaptor is used on heat/cool systems when you only have four
wires at the thermostat and you need a fifth wire for a common wire. Use the K terminal in place
of the Y and G terminals on conventional or heat pump systems to provide control of the fan and
the compressor through a single wire—the unused wire then becomes your common wire. See
THP9045 instructions for more information.
