* Remove factory installed jumper for two transformer systems. ** The THP9045A1023 Wire Saver module 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.
