The RC terminal has a cooling power supply on it. There is a heating power supply in the terminal. The RC and RH terminals are jumpered in a four-wire heat/cool system and a single-stage heat pump system but not in a five-wire heating/cooling system.
Do I use RC or Rh on thermostat?
Your thermostat’s power source is the red wire. A red Rc wire can be found on the thermostat if it is dedicated to air conditioning. The red Rc and red Rh wire are used for heating and cooling.
Should I use RC or RH?
Is the red wire going to RC or the other way around? There isn’t a standard for the color of the wire. The RC wire is referred to as red cooling. It’s the same thing with the thermostat’s power source.
Do I need a jumper between Rh and RC?
It’s a bad idea to put more than one wire into a thermostat connection. The internal jumper between the Rh and Rc is used by the Nest Learning Thermostats.
What is RC and Rh on a Nest thermostat?
Rc. is a form of taxation. If you do not have an Rh wire, the Rc wire is the power wire. The power wire for your cooling system should be the Rc wire.
Can an RC wire go into R?
If you have one wire that’s labeled RC, it goes into the R terminal, setting the jumper that connects the two terminals in place.
Is RC the same as C wire?
The wires aren’t the same. The wiring of the previous thermostat should be followed when installing this thermostat.
Is RC or RH for heat pump?
The RC terminal has a cooling power supply on it. There is a heating power supply in the terminal. The RC and RH terminals are jumpered together in a four-wire heat/cool system and a single stage heat pump system but not in a five-wire heating/cooling system.
Why connect RC and Rh?
Rh and Rc are related to Red-Heat and Red- Cool. The jumper between Rh and Rc is required if you only have one red wire. A compressor is yellow or Y. There is a heating element.
What if there is no C wire for thermostat?
G-wires can be used if there is no hidden C-wire. You won’t be able to use your fan on your own if the heating or cooling isn’t on. Many heating and cooling systems are not compatible with the solution.
What does no power to Rh wire mean?
There’s a chance that the problem with your air conditioning is with the float switch. If you have too much water in the pan, the float switch will prevent your AC from turning on.
What does B mean on a thermostat?
The O and B wires switch the valve between heating and cooling.
Why is there no yellow wire on my thermostat?
If there are no yellow wires, it’s likely because the manufacturer chose to color the wire blue. It is possible that the second wire is colored light blue if you know that your system has two stages of cooling.
What is the best setting for Nest thermostat?

Does the Rh or RC matter on a Nest?
