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.
