Learning Thermostat Install - R/Rc Jumper. Having some trouble installing my new learning thermostat. I've got an older thermostat with 4 wires, a Y1, G, W1, and R. There is a jumper between the R and Rc terminal. When trying to setup my nest thermostat I've put the R wire into both the Rh and Rc terminals on separate occasions, but in either ... OLD Thermostat: G – G wire, W – W wire, Y – Y Wire, Rc + Rh (R wire with jumper between Rc and Rh) New Thermostat : needs a C wire. Due to old heater panel, I could not find the C wire to hook up. So, hooked up external transformer and connected to C and Rc. Removed jumper between Rc and Rh as suggested by Bill Lee below. …Radio controlled (RC) airplanes have been around since the early 1900s, and they are still a popular hobby today. RC airplanes are miniature model aircraft that are powered by an e...If your old thermostat had both R and RH wires, remove metal jumper. Connect the R wire to the RC terminal, and the RH wire to the R terminal. Remove metal jumper connecting R and RC only if you must connect both R and RC.

However, the heating still needs to be controlled, so a wire known as a jumper is connected between the RC and the RH terminals so that power gets to the heating control part of the thermostat. Does RH go to R or RC? Some thermostats have a jumper switch, some …Ecobee3 Heating - RC vs RH. Ecobee3 has been working fine this summer for cool. Last night house was down to 60F so I switched to heat. Immediately the fan came on - so I switched it to furnace control rather than thermostat control. But no heat would ever come on. So I switched the red wire from RC to RH - now heat comes on, but A/C no longer ...The RC and RH terminals are Red Heat and Red Cool, a long time ago General Electric made HVAC systems with 2 transformers, 1 for Cool and 1 for Heat, thus the RH and RC terminals, thermostats come with a jumper wire between RC and RH so modern single transformer systems can run their Red thermostat wire to either RC or …R wire - Power [R+Rc joined by jumper] Y wire - Compressor contactor C wire - 24VAC common O/B wire - Changeover valve G wire - Fan relay. 2H/1C Heat Pump System: NOTE: If dual fuel, TH6320WF (Trade FocusPRO WiFi 6000 only) R wire - Power [R+Rc joined by jumper] Y wire - Compressor contactor C wire - 24VAC common O/B wire - Changeover valveIn most cases, the Rc wire is used for cooling systems, while the Rh wire is used for heating systems. The Rc stands for “red cooling,” and it powers the cooling system. On the other hand, the Rh stands for “red heating,” and it powers the heating system. However, it is important to note that there is no standard color coding for these ...The Rc and Rh may or may not be connected. If yes, then there will be a red wire indicating the jumper between them. The Rc stands for red cooling. Comparing the Rh wire, it activates the thermostat but supplies the cooling system. So, for its connection, if you have all three wires, such as Rh, Rc, and R, you need to connect the Rc wire to the ...Rc and R are the same terminal. For nest you don't need a jumper. The reason for the 2 terminals is so you can use one thermostat for 2 types of units. Rc is for the indoor air handler when you run the AC. R is for the boiler that does your radiator heat, sometimes you see RC and RH, c is for cool h for heat.Ecobee3 Heating - RC vs RH. Ecobee3 has been working fine this summer for cool.

So I switched the red wire from RC to RH - now heat comes on, but A/C no longer ...35. A thermostat basically just energizes the individual circuits (G (fan), W (heat), Y (cool) ) which in turn (via the furnace controller) powers a relay which provides line voltage to the actual units (like the fan or A/C. In the case of heat, it instructs your furnace to open the valve supplying gas). R (or Rh and Rc) provides the 24VAC power.If your old thermostat had both R and RH wires, remove metal jumper. Connect the R wire to the RC terminal, and the RH wire to the R terminal. Remove metal jumper connecting R and RC only if you must connect both R and RC.
