Can you Jumper a thermostat?
Some thermostats have a jumper switch, some have a metal staple, others may have a plug, and the jumper may also just be a wire connecting the two terminals. If you have two wires, R or RH will go into the R terminal, and RC will go into the RC terminal. This wire will go to the G terminal on your new thermostat.

Why is there a jumper between RC and RH?
Effectively there isn’t a second RH wire, although there is an RH terminal. 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.
How do you put a jumper wire on a thermostat?
To create a new jumper for RC/RH, use a short piece of thermostat wire, strip the insulation off both ends of the wire and bend it in half. Connect one end to RC and the other end to RH on the wall plate. Leave the wire that comes out of the wall attached to either RC or RH.
Why is my thermostat not communicating with AC unit?

Why is my thermostat not hardwired?
If your thermostat wall does not have a c-wire, or common wire, your thermostat most likely is not hooked up to your HVAC system for its power and needs batteries. When your screen is blank, it could indicate you need to replace the batteries. Most thermostats display a low-battery symbol when the juice is running low.
What do you do if your AC compressor stops working?
You will want to have the unit examined to look for signs of a blown fuse, a tripped circuit breaker, a broken thermostat, or dirty air filters. Dirty or clogged filters commonly make AC compressors stop working.

Does red wire go to RC or RH?
There is no standard for the colour of the RH wire, but most units use a red one. The RC wire, on the other hand, refers to “red cooling”. It’s the same with the RH wire in that it powers the thermostat. For the RC, it powers the cooling system.
