A wire saver acts as a splitter for
applications that do not include a
24-volt C wire. If your heating/cooling
system does not include a C wire,
install the wire saver in or near the
main unit (furnace, air handler) of
your heating/cooling system.
What tools do I need to install it?
• Small, flat screwdriver
• Two-sided mounting tape (included)
• Thermostat wire bundle, ends
stripped (included)
