Remove The Old Thermostat Cover; Label Wires - Emerson White-Rodgers P210 Install Manual

3.2 Remove the old thermostat cover

Remove the old thermostat's front cover from the wall base. Some covers pull off easily, while others may need to
be removed by prying the cover off with a screwdriver.
Your old thermostat may have a sealed glass tube containing mercury. Be careful not to damage the tube or dispose of the tube in your trash.
For safe disposal information, please see Mercury Notice on page 43.

3.3 Label wires

Tip: Taking a picture with a camera or smartphone can help you not only remember how wires are connected
to the terminals, but can also ensure that you label your wires correctly.
Using your screwdriver, carefully unscrew one wire at a time from the terminal block and attach the corresponding
wire label sticker.
Please note that not all terminals may be used, and that there's no standard color code for thermostat wires, so
your wire colors may vary. For your reference, we've included a terminal label reference chart on page 7 to help you
connect the wires in your old thermostat to your new thermostat in case you get stuck.
