24V Power Adapter/Transformer, C-Wire Adapter for Ring Doorbell, Ecobee, Sensi and Honeywell Thermostats (25Ft Cable)

To prevent a lack of power output, it is essential to ensure that the terminals are stripped and the screw terminals are securely clamped into the thermostat to maintain good contact. It is strongly recommended to have a person with electrical expertise, such as an electrician, handle the installation. It is important to note that the initial ends on this wire are treated, and if you cut them to shorten the wire, the copper will be more challenging to insert into the thermostat with pinch vs. screw terminals, which will result in no power output.

For the Nest E thermostat, the 24V power adapter should be connected to the C and R pins (with the HVAC's Red line also connected to the R pin). For the Nest Learning Thermostat, 3rd generation, the adapter should be connected to the C and RC pins.

The 24V power adapter can be used to power popular smart thermostats, such as Honeywell, Ecobee, Emerson, and Sensi, as well as other devices that require 24V AC current for operation. It is important to note that the C wire adapter is not compatible with the Nest Learning Thermostat, 3rd generation.

The power adapter has the following technical specifications: Input voltage of 120V AC, 60Hz; Output voltage of 24V, 300mA/AC. The brand names mentioned are solely for demonstrating compatibility.

To install the adapter, it is crucial to ensure that the terminals are stripped and the screw terminals are securely clamped into the thermostat to maintain good contact. The 2-pin non-polarity wires are designed to ensure easy and error-free installation for installers of all skill levels and knowledge bases. If the wiring is complicated, it is recommended to seek assistance from a professional electrician.

The power adapter features an extra-long, 7.6M (25ft) cable, allowing for flexible installation along the wall and connection to the electrical outlet, whether inside or outside.

For the Nest E thermostat, the adapter should be connected to the C and R pins, with the HVAC's Red line also connected to the R pin. For the Nest Learning Thermostat, 3rd generation, the adapter should be connected to the C and RC pins.

For the Nest Learning Thermostat, 3rd generation, the wiring should be as follows: White wire to C, White/Grey striped wire to the same (along with) the Red wire to RC, Y1 (connected to the Blue wire), G (connected to the Green wire), RC (connected to the Red wire and the power adapter Grey and White wire, RC is to be connected to the 2 with the wire), and W1 (connected to the White wire) C (connected to the power adapter White wire).

By following these guidelines, you can ensure a successful and reliable installation of the 24V power adapter for your smart thermostat or other 24V-powered devices.
