) selection

button, two Adjustment buttons (▲&

), one Fan Speed ( ) selection button and one

On/Off (

) button.

安装

T6000温控器安装在用户容易观看屏幕和方便调节温度设定点的地方。并使温控器位

于能代表房间总体环境温度的地方。避免将温控器安装于冷热源附近，如通风口、加

热器、室外或阳光照射到的地方。

安装

T6000系列温控器设计为标准75x75x35mm墙装接线盒安装。 (见

图

: 拆开图)

按照指示打开后盖底座，把它安装在墙上并接线。

注意

所有T6000系列温控器型号，需要两枚Mx5安装螺钉 (盒中自带，如遗失，需采

用PWT2.5X5X5.5螺钉)。

Installation

Install the T6000 where the occupant can read the display and adjust the setpoint easily.

Situate the thermostat where the temperature is representative of the general room

conditions. Avoid installing the T6000 near cold or warm air drafts, radiant heat, on an

outside wall, or in direct sunlight.

Mounting

Mount the T6000 Series thermostat to a 75x75x35mm standard electrical wallbox. (See

Figure

)

Follow the instruction in removing the base and then proceed to the wall box Mounting and

the Wiring sections.

Note:

All T6000 Series models require two No. Mx5 mounting screws (Included in the box,

screw PWT2.5X5X5.5 is required if missing).

Removing the Base

Loosen (Do Not Remove) the single Phillips-Head retaining screw at the top of the case to

swing the thermostat slightly away from the base. By gently sliding it forward, the thermostat

hinge hooks come away from the hinge slots at the bottom of the mounting base to provide

easy access for mounting and wiring. The Printed Circuit Board (PCB) is attached inside the

cover with connection pin near the middle of the mounting base.

Do you have a question about the Johnson Controls T6634-TE21 and is the answer not in the manual?

The T6634-TE21/22 LCD Digital Fan Coil Thermostat is a modulating/floating thermostat designed for controlling fan coil units. It features a large LCD display for clear visibility of settings and status. The device is intended for use as an operating control in line voltage fan coil applications.

Function Description

The thermostat provides control over fan coil units, offering both modulating and floating control options. The T6634-TE21-9JSO model is for modulating applications, while the T6634-TE22-9JSO is for floating applications. An additional model, T6634-TE21-9JRO, supports modulating applications with a remote temperature sensor.

The device allows users to set the desired temperature, fan speed, and operating mode (Cool, Heat, or Fan Only). It incorporates a microprocessor for precise control and offers various user-selectable settings to optimize comfort and energy efficiency. The LCD display provides real-time feedback on the current temperature, setpoint, fan speed, and operating mode.

Important Technical Specifications

The thermostat operates on line voltage and is designed for use with fan coil units. It features a large LCD display with a backlight for improved visibility in various lighting conditions. The dimensions of the thermostat are approximately 126.0 mm (height) x 88.0 mm (width) x 27.0 mm (depth) when mounted. The mounting box dimensions are 75x75x35mm.

The device supports various fan speed settings, typically Low, Medium, and High, and can also be set to Auto fan speed mode. It includes a temperature adjustment button for fine-tuning the setpoint. The thermostat is designed for indoor use and should not be installed in condensing, wet, or damp environments.

Usage Features

The T6634-TE21/22 thermostat is user-friendly, with intuitive controls and a clear LCD interface.

Temperature Adjustment: Users can easily adjust the desired temperature using the up and down arrow buttons. A 5-second delay is incorporated before the new setpoint is displayed, allowing for quick adjustments without immediate screen changes.
Fan Speed Control: The thermostat offers multiple fan speed settings (Low, Medium, High) and an Auto mode. In Auto mode, the fan speed adjusts automatically based on the difference between the room temperature and the setpoint.
Operating Modes: Users can select between Cool, Heat, and Fan Only modes to suit their comfort needs.
Occupied/Unoccupied Mode: The thermostat supports an Occupied/Unoccupied mode, which can be activated manually or through a timer. In Unoccupied mode, the thermostat operates at a predefined energy-saving setpoint.
Timer Function: A timer function allows users to set a duration for the thermostat to operate in Occupied mode before returning to Unoccupied mode. This is useful for temporary comfort needs.
Keypad Lock: The keypad can be locked to prevent unauthorized changes to the settings.
Backlight: The LCD display features a backlight that activates with any button press and remains on for a short period, enhancing visibility.
Parameter Settings: The thermostat allows access to a parameter setting menu for advanced configuration, including adjusting temperature offsets, fan control logic, and other system-specific settings. This menu is typically accessed by pressing and holding specific buttons for a few seconds.

Maintenance Features

The T6634-TE21/22 thermostat is designed for reliability and ease of maintenance.

Wiring Connections: All wiring connections should be made in accordance with local, national, and regional regulations. It is crucial to disconnect the power supply before making any electrical connections to prevent electrical shock.
Mounting: The thermostat is designed for easy wall mounting using a standard 75x75x35mm electrical wall box. The mounting process involves securing the backplate to the wall box and then attaching the thermostat body.
Troubleshooting: The manual provides troubleshooting guidance for common issues, such as the display not working or incorrect temperature readings. In case of a malfunction, it is recommended to check wiring connections and power supply first.
Product Warranty: The product warranty is void if the PCB is removed from the enclosure cover. This emphasizes the importance of not tampering with internal components.
Grounding: Proper grounding of the thermostat is essential to prevent electrical shock and ensure safe operation.
Unused Wire Leads: Any unused wire leads must be insulated and secured before applying power to prevent property damage, electrical shock, and personal injury.

Important Considerations:

The T6000 Series Line Voltage Fan Coil Thermostat should only be used as an operating control. Additional safety devices, such as supervisory or alarm systems, should be incorporated into the system to prevent personal injury or property damage in case of thermostat failure.
The thermostat should not be installed in environments with condensation, moisture, or dampness, as this can cause damage.
All wiring connections must adhere to the specified electrical ratings of the T6000 Series thermostat.
Do not apply power to the system before checking all wiring connections to avoid short circuits or improper connections that could lead to permanent damage to the equipment.
