Nest thermostats are designed to use very little power, and in many cases they can use your system’s heating and cooling wires to get enough consistent power. Although Nest thermostats would generally work without a common (C) wire, there are some systems that would require a C wire on the Nest thermostat like a heat only or cool only systems. And sometimes, you may need to connect a common wire (C wire) or power accessory, like the Nest Power Connector, to make your system compatible. You may also need the power connector or a C wire in these cases: - When you set up your thermostat, the Google Home app tells you that you need the Power Connector or a C wire. - Your thermostat screen shows a power-related help code, such as E1, E297, N260 or N261. - Your thermostat screen shows “Very low battery. Replace now and install stable power source.” - Your thermostat battery keeps draining. - Your thermostat keeps disconnecting from Wi-Fi.
