Terminal can be jumped using Slider Tab. See “Setting Slider Tabs” above.
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.
