Keeping this in consideration, do you need AC wire for thermostat?
The C wire, or “common wire” enables the continuous flow of 24 VAC power to the thermostat. If your system doesn't have a C-wire, you'll need to run a new cable from your furnace to your thermostat to install most of the modern smart thermostat models. Thermostat wire is just a big spool of bundled, color-coded wires.
Furthermore, will ecobee work with 2 wires? ecobee thermostats require a C (common) wire to power on. If you only have two wires at your current thermostat, there are a few installation options available, depending on your application. Note: You will not be able to install the Power Extender Kit (PEK) with heat-only 2-wire systems.
People also ask, what wires does ecobee need?
Depending on your system, the Power Extender Kit (PEK) included in the box with every ecobee may be able to provide a C wire connection.
How many wires do I need to install an ecobee thermostat?
|Type of system||Minimum wires needed||PEK compatible?|
|Cooling-only||4 (R, C, G, Y) 3 if PEK is used||Yes|
Is RC same as C wire?
RC and RH. If the air conditioning thermostat has one transformer to power both the heating and cooling system, then the wire from the transformer goes directly to the RC terminal and is called the RC wire. Effectively there isn't a second RH wire, although there is an RH terminal.
