Setup and Installation

The 24 Volt Power Adapter is designed to provide continuous power to devices that require a C-wire (common wire) or a dedicated 24V AC power source. The 25-foot cable allows for flexible placement of the adapter near an electrical outlet while reaching your device.

Connecting to Smart Thermostats

This adapter is compatible with various smart thermostats, including models from Ecobee, Sensi, and Honeywell, that require a 24V AC C-wire for consistent power. It is generally not compatible with Nest Learning Thermostat 3rd generation.

1. Identify Thermostat Terminals: Locate the C (Common) and R (Power) terminals on your thermostat's wiring base. Some thermostats may have Rc (Cooling Power) and Rh (Heating Power) terminals. If only one R terminal is present, use that. If both Rc and Rh are present, you may need to connect one wire to C and the other to either Rc or Rh, depending on your thermostat's specific requirements. Consult your thermostat's manual for precise wiring.
2. Prepare Wires: The adapter's cable has two bare wire ends. Ensure they are stripped appropriately to expose enough copper for connection.
3. Connect Wires: Connect one wire from the adapter to the 'C' terminal and the other wire to an 'R' terminal (either R, Rc, or Rh) on your thermostat. The adapter provides AC power, so the polarity of these two wires does not matter.
4. Secure Connections: Tighten the terminal screws to ensure a secure connection.
5. Plug in Adapter: Plug the WUYELIN 24 Volt Power Adapter into a standard 120V AC wall outlet.

Connecting to Ring Doorbells

The adapter can also provide continuous power to Ring doorbells, eliminating the need for battery charging. Ensure your Ring doorbell model supports external power input.

1. Access Doorbell Terminals: Remove your Ring doorbell from its mounting plate to access the wiring terminals.
2. Prepare Wires: Strip the ends of the adapter's 25-foot cable to expose enough copper for connection.
3. Connect Wires: Connect one wire from the adapter to each of the two terminals on the back of your Ring doorbell. The polarity does not matter for AC power.
4. Secure Connections: Tighten the terminal screws to ensure a firm connection.
5. Mount Doorbell: Re-mount your Ring doorbell to its plate.
6. Plug in Adapter: Plug the WUYELIN 24 Volt Power Adapter into a standard 120V AC wall outlet.

Operating Instructions

Once properly installed and plugged into a power outlet, the WUYELIN 24 Volt Power Adapter/Transformer will continuously supply 24V AC power to your connected device. No further user interaction is required for its operation. The connected device (thermostat or doorbell) will draw power as needed.

Maintenance

The WUYELIN 24 Volt Power Adapter/Transformer requires minimal maintenance. Keep the adapter and its cable clean and free from dust. Do not attempt to open or repair the adapter. If the cable or adapter housing is damaged, discontinue use and replace the unit.

Troubleshooting

• Device not powering on:
  • Ensure the adapter is securely plugged into a working wall outlet.
  • Verify that the wires are correctly and securely connected to the device's terminals.
  • Check for any loose connections or damaged wiring.
  • Confirm device compatibility with a 24V AC power source.
• Intermittent power:
  • Inspect all wire connections for looseness or corrosion.
  • Ensure the wall outlet is providing consistent power.
• Adapter feels warm:
  • It is normal for power adapters to feel slightly warm during operation. If it becomes excessively hot or emits a burning smell, immediately unplug it and discontinue use.
