Wiring UWP
Push down on the tabs to put the wires into the inner
holes of their corresponding termi nals on the UWP (one
wire per terminal) until they are firmly in place. Gently
tug on the wires to verify they are secure. If you need to
release the wires again, push down the terminal tabs on
the sides of the UWP.
Setting Slider Tabs
Set R Slider Tab.
• Use built-in jumper (R Slider Tab) to
differentiate between one or two transformer
systems.
• If there is only one R wire, and it is connected
to the R, Rc, or RH terminal, set the slider to
the up position (1 wire).
• If there is one wire connected to the R
terminal and one wire connected to the Rc
terminal, set the slider to the down position (2
wires).
NOTE: Slider Tabs for U terminals should be left
in place for other thermostat models.

** The THP9045A1098 C-wire adapter 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.
