セットアップとインストール

Proper installation is crucial for the optimal performance of your thermostat. If you are unsure about any steps, consult a qualified HVAC technician.

1. 安全上の注意

• Turn off power to the heating and cooling system at the main fuse or circuit breaker panel before beginning installation.
• Ensure all wiring connections are secure to prevent electrical shorts or hazards.

2. 古いサーモスタットの取り外し

1. HVAC システムの電源をオフにします。
2. 古いサーモスタットのカバーを取り外します。
3. 参考のために既存の配線接続の写真を撮ります。
4. Label each wire with the terminal designation it was connected to (e.g., W for Heat, G for Fan, Y for Air Compressor, R for Power).
5. Carefully disconnect the wires and remove the old thermostat base from the wall.

3. 新しいサーモスタットの取り付け

1. Feed the thermostat wires through the opening in the new thermostat base.
2. Secure the thermostat base to the wall using the supplied screws and anchors.
3. Ensure the base is level for accurate temperature readings.

4. 配線接続

Connect the labeled wires to the corresponding terminals on the new thermostat base. Refer to the wiring diagram provided with your unit for specific connections. Common connections include:

• R (or Rh/Rc): 24VAC Power (often red wire)
• W: Heat (often white wire)
• Y: Air Compressor / Cool (often yellow wire)
• G: Fan (often green wire)
• O / B： Heat Pump Reversing Valve (if applicable)

Note: If your system has separate transformers for heating and cooling, ensure the Rh and Rc terminals are connected correctly, or remove any jumper if instructed by your system's wiring diagram.

5. System Type Selection (Gas/Electric)

Locate the Electric/Gas switch inside the thermostat unit. Set this switch according to your heating system type:

• 設定 電気 for Heat Pump or electric heat applications.
• 設定 ガス for gas or oil applications.

6. バッテリーの取り付け

1. Open the battery compartment, usually located at the bottom front of the thermostat.
2. Insert the two "AAA" batteries, ensuring correct polarity (+ and -).
3. 電池ケースをしっかりと閉めてください。

Note: Some models may have a protective tab to remove before first use.

7. Completing Installation

The System switch controls the overall mode of your HVAC system:

• 涼しい： 室温が設定温度を超えると、サーモスタットが冷却システムを起動します。
• OFF： The heating and cooling systems are turned off. The fan can still be operated manually if set to ON.
• 熱： 室温が設定温度を下回ると、サーモスタットが暖房システムを作動させます。

メンテナンス

1. バッテリーの交換

Replace the two "AAA" alkaline batteries annually, or immediately when the low battery indicator appears on the display. To replace:

1. 電池ケースを開けます。
2. 古い電池を取り外します。
3. Insert new "AAA" alkaline batteries, observing correct polarity.
4. 電池ケースを閉じます。

Note: Always use fresh alkaline batteries. Do not mix old and new batteries, or different types of batteries.

2. サーモスタットの清掃

サーモスタットの外側を掃除するには、柔らかくて乾いた布で優しく拭いてください。amp 布で拭いてください。研磨剤入りの洗剤や溶剤は、表面や内部部品を傷める恐れがあるため、使用しないでください。
