If you have a heat-only system, you may notice that your thermostat has three wiresR, G, and W. There are three options available to create a C wire and make the ecobee compatible.
Can I use ecobee without C wire?
Even though it comes with an adapter for missing c-wires, ecobee is what we’d pick even for systems with a c-wire. If you’ve got a 24v HVAC system but no C-wire, check out the ecobee product line. Every ecobee ships with an adapter that you can install yourself at your furnace to make up for a missing C-wire.
How many wires do you need to hook up a smart thermostat?
In order to use an adapter kit, there must be a minimum of four wires currently present on your thermostat and HVAC system.
Does ecobee need a jumper?
The Ecobee3 connects the Rc and Rh terminals automatically which means you can choose either Rc or Rh to plug the wire into. It also means no jumper bridge is needed.
What if my thermostat only has 3 wires?
If you have a heat-only system, you may notice that your thermostat has three wiresR, G, and W. In this scenario, the Power Extender Kit (PEK) is not compatible. There are three options available to create a C wire and make the ecobee compatible.
Why does my thermostat have three wires?
The 3 wires you will find usually have codes R, G, and W. The difference between 2 wire and 3 wire thermometer is the G or green wire that is usually used for fans. In the 3 wire thermostat wiring, the green wire serves as a repurposed C or Common wire.
How many Ecobee do I need?
‘ it depends on the zoning in your house. If your house is a two-story apartment, then you would definitely need two Ecobee thermostats for each of the stories, in order to keep a balanced temperature of the house and maintaining the thermal atmosphere.
What is C wire required?
A common wire (C-Wire) provides Wi-Fi thermostats continuous power by connecting it to a heating and cooling system (e.g. furnace). C-Wires are required on most Honeywell Wi-Fi thermostats, with the exception of the Smart Round Thermostat (formerly known as the Lyric Round).
Does Ecobee work with stranded wires?
If you have a high-voltage setup, a smart thermostat isn’t going to work. For Ecobee thermostats, 120V and 240V systems (such as baseboard heating) will not work at all.Google Nest also points out that its thermostats won’t work with systems that use stranded wires or stranded wires that are connected by a wire nut.
Is white wire always neutral?
The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.This is to prevent the electricity from running through you!
What is the O B wire?
O, B, O/B: These wires are responsible for switching the changeover valve in a heat pump system. The O wire reverses the valve from heating to cooling, and the B wire switches the valve from cooling to heating. Sometimes it might be a single O/B wire instead of two separate wires.
Where does Aux wire go on Ecobee?
If you have a heat pump system with auxiliary heating, you will normally connect the wire labelled AUX/AUX1 or W2 to the ecobee’s W1 terminal. If you have two stages of AUX heat, connect the AUX2 wire to the ecobee’s W2 terminal.
What is the AUX wire on a thermostat?
Some HVAC systems support auxiliary heat (AUX) as well as emergency heat (E).A thermostat senses this and automatically turns on electric heat strips to provide the additional heat needed. Some thermostats have an E wire. The E wire controls emergency heating.
What happens if you wire a thermostat 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.
Can I use a 4 wire thermostat on a 2 wire system?
Yes, you can connect a four wire thermostat to this setup. Connect the white wires in the same manner as the black wires are connected.
Why does my thermostat only have two wires?
If your heating system has only two wires, the job of the thermostat is simple. All it has to do is turn the heat or the cooling on and off.There’s also no thermostat blue wire, or common wire, to power the thermostat, so it has to operate on its own, either using batteries or mechanical temperature detection.
Can I have multiple ecobee thermostats?

Can one ecobee control multiple zones?
The Ecobee thermostat can be used to create up to 16 different zones to control your home’s temperature.The Ecboee Smart Sensor/Room Sensor can connect up to 32 devices to your Ecobee thermostat. There are multiple reasons for wanting to create zones in your home.
How do I know if I have C wire?
It is easy to see if you already have a c-wire connected to your system. Simply remove your current thermostat face from its baseplate and look for the terminal labeled with the letter c. If this terminal has a wire attached to it, you have an active c-wire.
What does a neutral wire do?
Neutral wire carries the circuit back to the original power source. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. This gives currents circulation through your electrical system, which allows electricity to be fully utilized.
