Wallplate
Important! The Z-Wave thermostat requires a C wire to operate. The C, or common,
wire brings 24 VAC power to the thermostat. Many older mechanical or battery operated
thermostats do not require a C wire. If you don’t have a C wire, try:
• Looking for an unused wire that is pushed into the wall. Connect that wire to C and
check that it is connected to the 24 VAC common at your heating/cooling system.
Note: Not all heating/cooling systems label the 24 VAC common C. Check your system
manual or contact the manufacturer to find out which terminal is the 24 VAC common.
Wiring
For conventional heating/cooling systems (natural gas, oil or electric furnace, air
conditioner), see page 6. See “Glossary” on page 25 for further definition.
For a heat pump system, see page 6. See “Glossary” on page 25 for further
