4. Using the provided stickers, label each wire
according to the chart.
• If the terminals are not labeled, contact a qualied
HVAC technician.
•Note: Wire colors do not always comply with
standards, so wire color should be ignored. Refer
to the existing terminal designation for proper
identication.
• *If wires marked Y & C are both present, C may
be a Common wire and should not be used. If you
have a wire marked C, do not connect it to any
terminal. This wire is used only for non-battery
powered thermostats.
5. Do not let the wires slip back into the
wall during disconnection. You may want
to secure the wires to the wall as you
disconnect them. After all wires are labeled,
disconnect each wire and remove the
existing wall plate.
