uninstalling the existing unit  
1. Turn the system power OFF from the existing thermostat. Turn  
the power to the HVAC system OFF at the main power panel or  
at the furnace.  
(Failure to turn off the power to the existing thermostat before  
removal could damage your system.)  
2. Remove the existing thermostat cover to access the wires from  
the wall.  
(Some thermostats may have multiple covers, screws or other  
locking devices that must be removed or disengaged. See page  
8 for common examples.)  
3. Locate, but do not disconnect the wires.  
(If wires are not visible, they may be connected to the back  
of the wall plate. Some models may have doors that open to  
expose the wires and mounting screws.)

4. Using the provided stickers, label each wire according to the  
Wire Labels chart. (If the terminals are not labeled,  
contact a qualified 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 identification.  
*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.  
(Any unused wires should be capped with an approved electrical connector,  
such as electrical tape.)
