5. セットアップとインストール
5.1 取り付け
- Choose a suitable location for mounting the controller, away from direct heat sources, moisture, and vibrations.
- ユニットの周囲に十分な換気を確保してください。
- Cut a rectangular opening in the panel according to the controller's dimensions (refer to the product diagram for exact measurements).
- Insert the controller into the opening and secure it using the provided mounting clips.
5.2配線
警告： 配線する前に必ず電源を切ってください。
- 電源： Connect the main power supply (L and N) to the designated terminals on the controller.
- 温度センサー: Connect the NTC temperature sensor to the sensor input terminals. Ensure correct polarity if applicable. The sensor should be placed in the area where temperature needs to be monitored and controlled.
- コンプレッサー出力: Connect the compressor's power line to the compressor relay output terminals.
- Defrost Heater Output: Connect the defrost heater's power line to the defrost relay output terminals.
- ファン出力: Connect the evaporator fan's power line to the fan relay output terminals.
Refer to the wiring diagram printed on the side of the controller or in the specific model's manual for precise terminal connections.
6. 操作手順
6.1 電源オン/オフ
- To power on, connect the main power supply. The display will show the current temperature.
- To power off, disconnect the main power supply.
6.2 View温度
The current measured temperature is continuously displayed on the front panel.
6.3 パラメータの設定
The controller allows adjustment of various parameters such as setpoint temperature, differential, defrost cycle, and fan operation. The exact procedure may vary slightly by model, but generally follows these steps:
- を押し続けます SET / OK button for 3-5 seconds to enter parameter setting mode.
- 使用 UP そして 下 buttons to navigate through the parameter codes (e.g., F1, F2, P1, P2).
- プレス SET / OK に view 選択したパラメータの値。
- 使用 UP そして 下 ボタンで値を調整します。
- プレス SET / OK again to confirm the new value and move to the next parameter, or press and hold SET / OK to save all changes and exit the setting mode.
一般的なパラメータは次のとおりです。
- Set Point (SP): 希望する温度。
- Differential (Hy): The temperature difference between the set point and the turn-on/off temperature.
- Defrost Cycle (Id): Interval between defrost cycles.
- Defrost Duration (Ed): Length of the defrost cycle.
- Fan Control (Fc): Settings for fan operation during refrigeration and defrost.
7. メンテナンス
7.1 クリーニング
- 定期的にフロントパネルを柔らかくて乾いた布で拭いてください。amp 布で拭いてください。研磨剤や溶剤は使用しないでください。
- 過熱を防ぐために、通気口にほこりやごみがないことを確認してください。
7.2 Sensor Check
- Periodically inspect the temperature sensor and its wiring for any damage or corrosion.
- Ensure the sensor is securely placed and making proper contact.
8。 トラブルシューティング
| 問題 | 考えられる原因 | 解決 |
