Thermostat Wiring Letters : Thermostat Wire Reference Chart / What thermostat wire labels mean.. The thermostat uses 1 wire to control each of your hvac system's primary functions, such as heating, cooling, fan, etc. In general, the thermostat wire colors match the first letter of terminal names such as red wires for r terminals (for power), yellow wires for the y terminal (for cooling), white for the w terminal (for heating), green wires for the g terminal (for the fan). How do i pair my hive thermostat with my hive hub? The app will give you a custom wiring diagram to help you install the nest thermostat. Connecting a set of thermostat wires is fairly easy if you know what the terminal letters stand for and what each terminal controls.

L1 and l2, or 110, 120 or 240 volts In general, the thermostat wire colors match the first letter of terminal names such as red wires for r terminals (for power), yellow wires for the y terminal (for cooling), white for the w terminal (for heating), green wires for the g terminal (for the fan). The 5 strands of wire provide enough functions for the modern. Generally the red is your hot wire, straight from transformer that supplies constant power to your thermostat, which when each function, ie, cool, or heat is engaged, allows connection between red and whichever wire is called for by the thermostat.

These wire labels indicate a proprietary system that isn't compatible with ecobee thermostats. W (white) controls the auxiliary heating elements. At every stage, we will point out what 2 wire or 5 wire thermostats are used to wire, for example, to get a bigger picture of where those color wires go and how they enable the functions of air conditioners and furnaces. As shown these thermostat wire connections are for a heating only or heating and cooling system (not heat pumps) using a single 24vac transformer for power. Generally the red is your hot wire, straight from transformer that supplies constant power to your thermostat, which when each function, ie, cool, or heat is engaged, allows connection between red and whichever wire is called for by the thermostat.

How can i tell if my wires are inserted properly? Knowing what each letter stands for and what it's used for can help you figure out which wire goes where on your new thermostat. Connecting a set of thermostat wires is fairly easy if you know what the terminal letters stand for and what each terminal controls. The wiring of your thermostat appears complicated, but when you understand the basic structure of it, including the terminals and thermostat wiring colors, it's much less overwhelming of a task to install your own system. These wire labels indicate a proprietary system that isn't compatible with ecobee thermostats. While thermostat wiring only utilizes 24 volts (thus it won't shock you or is even detectable), it's still a good idea to shut the power off to your entire hvac system before replacing the thermostat, so. Do i need to use all the wires coming out of my wall for my hive thermostat? See the diagram below for what each wire controls on your system: How do i pair my hive thermostat with my hive hub? The yellow wires connect to the y terminals on your thermostat. The hvac wiring is coded based on the action it performs while where the wire goes determines the terminal. It terminates at the air handler or furnace. An important thing to note is that the actual instructions for wiring thermostats is really a 'cheat sheet'.
Color of wire and termination: While thermostat wiring only utilizes 24 volts (thus it won't shock you or is even detectable), it's still a good idea to shut the power off to your entire hvac system before replacing the thermostat, so. Y = yellow, g = green, r=red, w = white. The yellow wires connect to the y terminals on your thermostat. Trane uses numbers and the new one uses the normal letters.

Each terminal is marked with a letter that usually corresponds to the color of the wire that should be used to connect it. Generally the red is your hot wire, straight from transformer that supplies constant power to your thermostat, which when each function, ie, cool, or heat is engaged, allows connection between red and whichever wire is called for by the thermostat. For heat pumps there are typically o and b terminals also. W/ aux not used m32714 remove metal jumper if you have both r and rc wires. The main difference setting each apart is the number of colored wires. Here's a list of the basic terminal letters and their functions: The thermostat uses 1 wire to control each of your hvac system's primary functions, such as heating, cooling, fan, etc. A few exceptions are blue (or sometimes black) wires for the c terminal (common.
