Installing your thermostat
6 Mount wallplate for Z-Wave
thermostat.
Mount your new wallplate using
screws and anchors included with the
thermostat.
If necessary:
Drill 3/16-in holes for drywall.
Drill 7/32-in holes for plaster.
Note:
You may be able to use your
existing wall anchors. Hold the wallplate
up to the existing anchors to check for
alignment.
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.
