4. セットアップとインストール
4.1 サーモスタットの取り付け
The T4 Pro Thermostat uses a UWP (Universal Wiring Plate) mounting system for easy installation. Follow these steps:
- 回路ブレーカーで暖房/冷房システムの電源をオフにします。
- 古いサーモスタットを壁から取り外します。
- Mount the UWP to the wall using the provided screws and wall anchors. Ensure it is level.
- Connect the wiring as described in the next section.
- Snap the T4 Pro Thermostat onto the UWP.

4.2配線接続
The T4 Pro Thermostat supports 1 Heat/1 Cool conventional systems and 1 Heat/1 Cool heat pump systems. Refer to your system's wiring diagram. If a common wire (C-wire) is available, connect it to the 'C' terminal on the UWP for continuous power, reducing reliance on batteries. If no C-wire is present, the thermostat will operate on battery power.
一般的な配線端子:
- R/Rc: 24V AC power (heating/cooling)
- C: Common wire (optional, but recommended for continuous power)
- W/Aux: Heat (conventional) / Auxiliary Heat (heat pump)
- Y: Compressor (cooling)
- G: ファン
- O / B： Reversing valve (heat pump)
4.3初期構成
After installation and power restoration, the thermostat will guide you through initial setup. This includes selecting your system type (e.g., conventional furnace, heat pump) and other basic settings. Accurate configuration is crucial for optimal performance.
5. サーモスタットの操作

5.1ディスプレイオーバーview
The LCD screen displays the current temperature, setpoint, system mode, fan status, and programming information. The backlight illuminates the display for better visibility, though some users may find its brightness to be moderate.
5.2 基本的な制御
- 温度調整: 使用 + そして - buttons on the front of the thermostat to raise or lower the desired temperature setpoint.
- システム モード: Press the 'Mode' button (typically on the side or bottom) to cycle through available system modes: Heat, Cool, Off.
- ファンコントロール: Press the 'Fan' button to select fan operation: 'Auto' (fan runs only when heating/cooling) or 'On' (fan runs continuously).
6. サーモスタットのプログラミング
The T4 Pro Thermostat offers flexible programming options to suit your schedule and energy saving preferences. You can choose between 7-day, 5-2 day, or 5-1-1 day programming, or operate it as a non-programmable thermostat.
6.1 Setting a Schedule
Access the programming menu (refer to the on-screen prompts or specific button combinations in the full manual) to set up your desired temperature schedule for different times of the day and days of the week. Each programming period (e.g., Wake, Away, Home, Sleep) can have a unique temperature setpoint.
6.2 Temperature Holds
- 一時的な保留： Adjusting the temperature using the + or - buttons will temporarily override the schedule until the next programmed period begins.
- 永続的な保留： To maintain a specific temperature indefinitely, enter the 'Hold' function (usually by pressing a dedicated 'Hold' button or navigating through the menu). The thermostat will maintain this temperature until the hold is manually canceled.
7. メンテナンス
7.1 電池の交換
The thermostat requires two AA batteries for operation if a C-wire is not connected, or for backup power to maintain the clock and settings during a power outage. A low battery indicator will appear on the display when batteries need replacement. To replace:
- Gently pull the thermostat body away from the UWP mounting plate.
- 古い単三電池を取り外します。
- Insert two new AA alkaline batteries, observing polarity (+/-).
- Snap the thermostat back onto the UWP.
7.2 フィルター交換リマインダー
The thermostat can be configured to remind you when it's time to change your HVAC system's air filter. When the reminder appears, change the filter and reset the reminder through the thermostat's menu settings.
8。 トラブルシューティング
If you experience issues with your Honeywell T4 Pro Thermostat, refer to the following common problems and solutions:
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| 何も表示されない、または画面が空白になる | 電源がない、電池が切れている、または配線が緩んでいる。 | Check circuit breaker. Replace AA batteries. Verify secure wiring connections at the UWP. |
| System not responding (no heating/cooling) | Incorrect system mode, wiring issue, or HVAC system fault. | Ensure thermostat is in 'Heat' or 'Cool' mode. Check wiring. Consult an HVAC professional if the system itself is not functioning. |
| Display temperature seems inaccurate | Thermostat location, system cycling settings. | Ensure thermostat is not exposed to direct sunlight or drafts. Review advanced installer settings for cycles per hour (CPH) to optimize system performance. |
| バックライトが暗い | Normal operation for this model. | The backlight on this model is designed to be moderate. Ensure fresh batteries if operating without a C-wire. |
For more complex issues or if troubleshooting steps do not resolve the problem, contact Honeywell customer support or a qualified HVAC technician.
