or NOTE: The product data sheets list all installer setup options and is available at customer.resideo.com.
** 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.
