However, some thermostats will have a jumper wire that doesn't go back through the wall to connect to your system. Instead, a short jumper wire connects 2 thermostat terminals together. This is fairly common on the Rh and Rc terminals. . Nest thermostats don't use jumper wires Nest thermos...
Terminal R Rh Rc Wire Color 8 Write down the color of the wires Check mark the wires that are connected to terminals. Next to the check mark, write down the color of the wire. Do not include jumpers as a part of your count. Check all that apply (Not all will apply): Terminal ...
Remove any jumper wires (wires that connect to two terminals), like Rh to Rc. Using the wire labels provided, label each wire based on where it’s connected to the thermostat terminal—NOT based on the color of the wire. Disconnect the wires and unscrew the old thermostat base. Be carefu...
and 5 wire thermostats. At every stage, we will point out what 2 wire or 5 wire thermostats are used to wire, for example, to get a bigger picture of where those color wires go and how they enable the functions of air conditioners and furnaces. ...

The thermostat includes isolation circuitry housed within the thermostat to safely connect to the HVAC control wires and power wire(s) whether the HVAC system has one or two separate transformers without the use of removable jumpers or manual rewiring. The thermostat can include a processor that ...
The Honeywell RTH111 comes with a jumper wire installed between the Rh and Rc terminals. These supply power to the heating and cooling systems respectively. If you have only one power wire (which is usually red), leave the jumper in place and connect the wire to either Rc or Rh. However...
Mine did NOT use C, because it has it's own battery power. It had 2 connections for 'R' (Rc & Rh), which were jumpered together from factory. I left the jumper in place, and used 'Rc' and 'Y' for Cooling, and it works great. The Temp Controller actually had about 5 different...
