You would need a common wire to power the thermostat also, so one would need to be connected at some point in the wiring to the common side of the 24 volt transformer. The thermostat operates at low voltage (24 volts), so if you get a shock, it won't be a bad one. This transformer is located inside your hvac equipment.
In this hvac installation training video, i show how to wire the low voltage thermostat wires into a furnace and ac unit. Knowing what each thermostat wire does can help in wiring up a new or replacement room thermostat. Heck, now i'm not calling anyone a dummy! However, if the low voltage wires touch each other during the work, the system's internal fuse will blow. If you see 120 vac or 240 vac on the thermostat, a low voltage thermostat will not work with your system.
The orange thermostat wire links to your heat pump, if you have one. Troubleshooting your thermostat, wiring, voltag. The old thermostat may say somewhere on the thermostat that it is for 24 volt (24vac) or maximum 30 volts (30vac). Ask question asked 2 years, 8 months ago. The 2 wire thermostat for line voltage systems are technically known as single pole thermostat (and the 4 wire version is known as double pole thermostat). At 240 volts, a max load of 3500 watts can be. The main trouble is dealing with those different colored wires, knowing which one does what and if that wasn't enough, you also have numbers and letters to deal with. Nevertheless, no shock is better than a mild one, so play it safe and turn off the power whenever you're handling the wires.

Active 2 years, 8 months ago. A line voltage thermostat tends to have either double pole wiring or single pole wiring based on the thermostat and heater features. Viewed 9k times 1 i'm working on adding a smart thermostat, and as many older setups have it, my current thermostat doesn't have a 'c' wire. This article explains just what wire at a room thermostat actually controls. This type of wiring requires a line voltage thermostat and is not compatible with low voltage thermostats if you see wires connected to terminals labeled g1,g2,g3, you will need a thermostat capable of controlling multiple fan speeds, none of our retail thermostats are compatible with this system type. The 2 wire thermostat for line voltage systems are technically known as single pole thermostat (and the 4 wire version is known as double pole thermostat). The orange thermostat wire links to your heat pump, if you have one. In general, the following standards are used for wiring thermostats. A line voltage thermostat ranges from 120 to 240 volts. This additional terminal is labeled 'g' in the thermostat. The main trouble is dealing with those different colored wires, knowing which one does what and if that wasn't enough, you also have numbers and letters to deal with. Typically i see amperage ratings for these line voltage devices ranging from about 10.5a up to about 22a. The thermostat operates at low voltage (24 volts), so if you get a shock, it won't be a bad one.

Typically i see amperage ratings for these line voltage devices ranging from about 10.5a up to about 22a. The 2 wire thermostat for line voltage systems are technically known as single pole thermostat (and the 4 wire version is known as double pole thermostat). If you have baseboard or wall heaters, you likely have line voltage.
Heck, now i'm not calling anyone a dummy! If you're unsure of your system voltage, you or a contractor should measure voltage using a multimeter. In this hvac installation training video, i show how to wire the low voltage thermostat wires into a furnace and ac unit. Additionally, operating line voltage thermostats is straightforward and installing them is not a big deal. The old thermostat may say somewhere on the thermostat that it is for 24 volt (24vac) or maximum 30 volts (30vac). The thermostat operates at low voltage (24 volts), so if you get a shock, it won't be a bad one. At 240 volts, a max load of 3500 watts can be. The 2 wire thermostat for line voltage systems are technically known as single pole thermostat (and the 4 wire version is known as double pole thermostat).
G is compatible, but not g1,g2,and/or g3.
Each wire in the thermostat cable serves a different purpose. Sensi thermostat is not compatible with line voltage systems. The typical #18 awg wire used for thermostat wiring is expected to handle a maximum of 2.3a (for power transmission). In general, the following standards are used for wiring thermostats. The orange wire connects to terminal o on your thermostat. The thermostat uses the low voltage wires to send an electrical signal to the furnace or boiler, which is a way of providing commands to turn the heat or air conditioning on and off. Just like this, a '2 wire thermostat' can be either a line voltage model (operating at 120 v or 240 v) or a low voltage model (operating at 24 volts). See how the yellow wire from the thermostat is wire nutted to a red wire going off into a. The main trouble is dealing with those different colored wires, knowing which one does what and if that wasn't enough, you also have numbers and letters to deal with. This transformer is located inside your hvac equipment. Line voltage is more commonly used with radiant, convention, or resistance heat sources. Color of wire and termination. Viewed 9k times 1 i'm working on adding a smart thermostat, and as many older setups have it, my current thermostat doesn't have a 'c' wire.
It uses more power than low voltage thermostats because it delivers power directly to your heater. The orange thermostat wire links to your heat pump, if you have one. Ask question asked 2 years, 8 months ago. In the most basic system, this functionality is provided by use of a fan center relay, and the low voltage wiring to the thermostat now will require a minimum of three wires (for heat only units) and four wires (for heat / cool / fan) for control. It terminates in your outdoor condenser for reversing valve operation from hot to cold.
If you have baseboard or wall heaters, you likely have line voltage. Conduct a simple pretest you might not even have to remove the thermostat cover to find out if the unit has power.

It uses more power than low voltage thermostats because it delivers power directly to your heater. It is a red wire and comes from the transformer usually located in the air handler for split systems, but you may find the transformer in the condensing unit. Sensi thermostat is not compatible with line voltage systems. The thermostat uses the low voltage wires to send an electrical signal to the furnace or boiler, which is a way of providing commands to turn the heat or air conditioning on and off. In fact, many thermostats are powered by the 24 volts from the transformer. See how the yellow wire from the thermostat is wire nutted to a red wire going off into a. A line voltage thermostat will typically have wires larger than 18 gauge and may not have terminal labels. In general, the following standards are used for wiring thermostats. Just like this, a '2 wire thermostat' can be either a line voltage model (operating at 120 v or 240 v) or a low voltage model (operating at 24 volts). 4.5 out of 5 stars 185. Raym64 december 24, 2020, 5:20am #10 mine wouldn't power up until i hooked up the rc wire in addition to the rh wire even though i don't have ac either.
