Can you use stranded wire for thermostat?
Nest thermostats don’t support stranded wires, they require solid-core copper wires.
Why does my thermostat have a jumper wire?
Most of your current thermostat’s wires will be connected to your thermostat and go through the wall to connect to your HVAC system. 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 two thermostat terminals together.
Where does the jumper wire go on a thermostat?
You typically have one or two of those three. If you have one wire — even if it’s labeled RC — it goes into the R terminal, setting the jumper connecting terminals R and RC in place. Thermostats may have a jumper switch, metal staple, or plug. The jumper may also be a wire connecting the two terminals.
What happens if you connect thermostat wires wrong?
Potential consequences of improper installation could include: Electric shock. Blowing a circuit breaker. Damaging the thermostat unit, the electrical system or even the AC/furnace unit itself.
Is stranded wire better than solid?
Stranded wires offer superior bendability and flexibility, making them easier to route around obstacles than solid wires. Flexibility. Stranded wires are more flexible and can sustain more vibration and flexing without breaking.
Can stranded wire be connected to solid wire?

What is the W1 wire on a thermostat?
The W or W1 wire controls your heating system. In most systems, the Y or Y1 wire controls your cooling system. If you have a heat pump, your Y or Y1 wire controls your compressor. Your compressor is responsible for heating and cooling your home.
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.
What are some of the common mistakes when installing a thermostat?
4 Mistakes You May Be Making With Your Thermostat
- Not Using a Programmable Thermostat.
- Not Programming the Thermostat Properly.
- Bumping the Temperature Up/Down to Quickly Heat/Cool Home.
- Not Maintaining the Thermostat.
How do I know if I installed my thermostat correctly?
How to test if the thermostat is properly installed?
- Step 1 – Turn off HVAC power.
- Step 2 – Remove the thermostat cover.
- Step 3 – Remove wires from terminals.
- Step 4 – Turn HVAC power back on.
- Step 5 – Test other wires.
- The display.
- Incorrect temperature.
- Strange behavior.
Can I use stranded wire in place of solid wire?
In short, you may use stranded wire up to 6mm (10AWG) for enough flex if needed, other than solid wire is perfect. Solid wire is less likely to be affected by corrosion and vibration due to the less surface areas as compared to the stranded wire especially when used for outdoor applications.
Can you mix stranded and solid wire?
It is possible to mix a solid and a stranded wire but that does not necessarily mean that you should do it. Connecting a solid copper wire to a stranded wire is a relatively complex process. There is a significant chance that something may go wrong.
Is it OK to use stranded wire?
Stranded wire is more flexible and malleable than solid wire, and it won’t split or sever. It is often used for indoor applications such as electronic devices, circuit boards, and speaker wires.
Can stranded wire carry more current than solid wire?
Because of its thickness, solid wire has a decreased surface area that reduces dissipation. Because of the given thickness of stranded wire, i.e., it’s thinner, there are more air gaps and a greater surface area in the individual strands of wire. Therefore, it carries less current than similar solid wires can.
How do you remove a jumper from a thermostat?
Can jumper wires be soldered?
Uninsulated jumper wires shall be less than 25mm (0.984 in.) long, and shall not violate minimum electrical spacing requirements. Silverplated, stranded wire shall not be used. Jumper wires may be terminated and soldered into a via hole.
Can you jumper W1 and W2 on thermostat?
If W1 is only wired up, it will always run in 1st stage, 2nd won’t come on unless W2 is wired to a two stage t-stat, or jumper to it.
Does white wire go to W1 or W2?
Thermostat White Wire (“W1” or “W2” Wire)
W wires go directly to the source of heating; that may be a furnace (gas, electric, oil, you name it) or heat pumps (mini-split heat pumps included). W2 is designated for two-stage heating. Most heat pumps include second-stage heating and require the white W2 wire.
Why is there a jumper between RH and RC?
In most cases, the heating and cooling system share a single transformer by leaving the jumper in the lower right corner it connects the RC and RH to power heat and cool features.
Is RC same as C wire?
The C and Rc wires are not the same. To install this thermostat you should follow the exact same wiring of the previous thermostat.
What is a common problem with thermostat?
A common thermostat issue that usually results in the temperature never reaching what you have it set for. Grime can build up inside a thermostat. When this happens, the thermostat doesn’t correctly gauge the temperature of the air in your house. Older thermostats can be cleaned by dusting inside the cover.

Does it matter if you use stranded or solid wire?
In general, solid cables are better electrical conductors and provide superior, stable electrical characteristics over a wider range of frequencies. They’re also considered more rugged and less likely to be affected by vibration or susceptible to corrosion, since they have less surface area than stranded conductors.
