Cover  
Wallplate  
Your old thermostat may consist of:  
3 parts: a cover, base and wallplate  
or  
The Cover: This usually pulls off, but is sometimes secured by a  
screw which must be loosened.  
The Base: This either pulls off or needs to be removed by loosening  
2 parts: a cover and wallplate  
screws under the cover.  
The Wallplate: This is removed by loosening the screws that hold  
the thermostat to the wall.

2.1.2 Loosen all screws holding the old thermostat’s wallplate to  
the wall. Do not disconnect the wires from terminals. Allow  
the wallplate to hang loosely on the wires.  
2.2 Label and disconnect the wires  
2.2.1 Note you may see two types of wiring in the old thermostat:  
1. Wires leading from the wall to a  
wall  
terminal on the thermostat  
Wall opening  
2. Wires connecting one terminal to  
another (jumper wire).  
These don’t have to be labeled.  
Wallplate hanging on the wires  
Ignore wire colors. There is no standard color code for  
thermostat wires.  
Ignore existing wire labels, if they are present.  
Use the provided labels to label/re-label the thermostat wires.  
The new labels must remain on the wires at least until the  
installation process is complete.  
No two wires can have the same label.

2.2.3 After labeling all the wires, use a screwdriver to disconnect  
2.4 Match and connect wires  
each wire from its terminal. Remove the old thermostat.  
2.4.1 Match each wire coming from the wall to its corresponding  
terminal, as shown in the illustration below. Insert each wire into  
the hole on the side of its matching terminal. Using a screwdriver,  
tighten the screw securely. DO NOT REMOVE THE WIRE LABELS.  
Make sure that the wires don’t fall  
into the wall after you detach them from  
the old thermostat. You may choose to  
tape them to the wall or tightly wind them  
around a pencil or screwdriver.  
No thermostat installation uses all of the wires shown below.  
In most cases, between 4 and 5 terminals are wired. The remaining  
terminals will not be used.

2.4.2 In the new thermostat, a jumper wire  
connects the RC and RH terminals.  
Do not allow wires to touch each other or parts on  
the thermostat. Doing so could result in damage to your heating and  
cooling unit.  
If, in your OLD thermostat…  
Then…  
Terminals RC and RH (or 5, or R5)  
were connected by a jumper wire,  
…leave the jumper wire in place  
in the new thermostat.  
There was a terminal R, which you then  
labeled RC according to 2.2.2,  
…leave the jumper wire in place  
in the new thermostat.  
2.3.3 Move the wallplate aside. Drill the mounting holes using a 3/16"  
drill bit. With a hammer, tap the wall anchors, provided in the  
package, into the drilled holes.  
2.3.4 Position the wallplate on the wall again and screw the mounting  
screws into the wall anchors. Do not use a power screwdriver,  
you may damage your thermostat.  
Terminals RC and RH (or 5 or R5)  
were NOT connected by a jumper wire,  
…remove the jumper wire from the  
new thermostat.  
If you’re not sure whether terminals RC and RH were connected in your old  
thermostat, refer to your notes made in section 2.2.2.

Appendix: Heat Pump  
Identification  
1. How do I know if I have a Heat Pump?  
Check the documentation for your heating and cooling system or  
contact your HVAC contractor.
