セットアップとインストール
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.

- 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.
- ワイヤーを準備する: The adapter's cable has two bare wire ends. Ensure they are stripped appropriately to expose enough copper for connection.
- ワイヤーを接続する: 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.
- 安全な接続: Tighten the terminal screws to ensure a secure connection.
- プラグインアダプタ: Plug the WUYELIN 24 Volt Power Adapter into a standard 120V AC wall outlet.

- Access Doorbell Terminals: Remove your Ring doorbell from its mounting plate to access the wiring terminals.
- ワイヤーを準備する: Strip the ends of the adapter's 25-foot cable to expose enough copper for connection.
- ワイヤーを接続する: 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.
- 安全な接続: Tighten the terminal screws to ensure a firm connection.
- ドアベルの取り付け: Re-mount your Ring doorbell to its plate.
- プラグインアダプタ: Plug the WUYELIN 24 Volt Power Adapter into a standard 120V AC wall outlet.

操作手順
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.
メンテナンス
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.
