myTEM FT RGBW Modul MTRGB-100-FT

Product Overview

The myTEM FT RGBW Modul (Model: MTRGB-100-FT) is designed for controlling and dimming 4-coloured LED strips or 4-coloured LED bulbs. Its programmable behavior allows for flexible integration into smart home systems. The device is intended for installation within a flush-mounted box.

Safety Instructions

⚠️ WARNING!

• Operate this device only as described in the manual.
• Do not operate this device if it has obvious damage.
• This device shall not be altered, modified, or opened.
• This device is intended for use in buildings in a dry, dust-free location.
• This device is intended for installation in a flush-mounted box. After installation, it must not be openly accessible.

⚠️ To avoid electrical shock and/or equipment damage, disconnect power to the main fuse or circuit breaker before installation or maintenance. Prevent the fuse from being accidentally switched on again and check that the system is de-energized.

⚠️ The device shall be connected according to the wiring diagram only. Covers of the flush-mounted boxes must comply with relevant safety standards.

⚠️ The electrical installation must be protected with a fuse of max. 10 A.

⚠️ The myTEM FT RGBW Modul should be installed in a flush-mounted box (wall, ceiling) in compliance with relevant national safety standards and with a depth of not less than 60 mm.

❗ CAUTION!

This word warns of possible damage to property.

❗ The myTEM FT RGBW Modul and the LED lighting should be placed close to each other. The cross-section and cable length of the LED supply should be dimensioned so that the voltage drop is lower than 1 Volt. A cable with 1.5 mm² should therefore not exceed 5 m in length in order to be able to use the maximum drive power.

ATTENTION: This device is not a toy. Please keep it away from children and animals!

Please read the manual before attempting to install the device!

Functions

• Supply voltage device: 24 VDC with 4-pole push-in support terminals for further wiring. The device operates correctly even if the supply voltage drops down to 10 VDC.
• Outputs: Four dimmable, electronic MOSFET outputs (R/G/B/W) with 2 A per channel. This allows for 48 W per channel with a 24 VDC LED supply or 24 W per channel with a 12 VDC LED supply.
• Communication: CFT bus with free wiring according to the tree topology.

Installation

⚠️ WARNING! Depending on national safety standards, only authorized and/or trained technicians may be allowed to make electrical installations on the power supply. Please inform yourself about the legal situation before installation.

Use a separate LED supply per FT RGBW Modul. To avoid ground loops, do not connect its ground (GND) to the ground of the FT RGBW Modul.

⚠️ The maximum length of the cables on the output side must not exceed 2 m.

⚠️ Maximum loads must not exceed 2 A for each channel.

Installation Steps:

1. For your safety, switch off the mains voltage (break fuse) during installation. Make sure that wires are not short-circuited during and after installation, as this may damage the device.
2. Connect the device according to the circuit diagram of the myTEM ProgTool or the terminal assignment shown in the diagrams. Use solid wires (Ø0.8 mm) for supply and communication, stripped by 5 to 6 mm. Insert the conductors until they hit the backstop. Use up to 2.5 mm² wires as LED supply, stripped by 6 mm. Connect the 1.0 mm² strands to your loads via terminals, using the orange strand as power supply for the LED lighting.
3. Check the wiring and then push the device into the flush-mounted box.
4. Switch on the mains voltage and include the device with the myTEM ProgTool in the server.
5. Switch off the mains voltage and fit a cover over the flush-mounted box. When you switch the mains voltage back on again, your device is ready.

Diagram Description (Network Structure): The network structure is depicted as a tree topology, illustrating how the CFT bus can be wired with free connections, allowing for a distributed network.

Diagram Description (Wiring - Page 1): This diagram details the terminal connections for the myTEM FT RGBW Modul. It shows input terminals for 24 VDC power supply (V+, GND), CFT bus communication (CFT-, CFT+), and four output channels (R, G, B, W) for controlling LED loads. It also indicates separate inputs for the LED power supply (12/24 VDC) and specifies the wire color for each LED channel (R-Red, G-Green, B-Blue, W-White).

Diagram Description (Wiring - Page 2): This diagram shows the module's integration within a smart home system. It depicts connections for the 24 VDC supply, a separate 12 or 24 VDC LED supply, and the communication link to the FT Base Module via CAN+ and CAN- terminals. A critical note explains that ground (GND) is essential for reliable communication but must be connected at only one point to prevent ground loops. Test points are also visible for voltage checks.

Diagram Description (Dimensions): The module's physical dimensions are 44 mm (Width) x 41 mm (Height) x 18.5 mm (Depth). It is designed for installation in a standard flush-mounted box, requiring a minimum diameter of 60 mm and a minimum depth of 60 mm.

Note on Terminals: To release a wire from a push-in terminal, hold it firmly and pull it out of the terminal by simultaneously twisting it back and forth. ⚙️

LED Display and Behavior

The LED next to the wires may show the following states:

• LED flashing green: Device is connected to the FT Base Modul and is in normal operating mode.
• LED green: Device gets network configurations from the FT Base Modul.
• LED flashing blue: Device is identified using the myTEM ProgTool.
• LED flashing green and red: Device started and connected to the FT Base Modul but not yet added to a Smart Server or Radio Server. (Requires an action in myTEM ProgTool.)
• LED red: Device started but has no connection to the FT Base Modul.
• LED off: Device not powered, not started, or broken.

Behavior after power failure

After a power failure, all outputs are switched off until the new settings are received from the Smart Server or Radio Server.

Troubleshooting

The following hints may help solving trouble:

1. Make sure that the power supply is connected with the correct polarity. With wrong polarity, the device does not start.
2. Make sure that the voltage has not dropped below the allowed operating voltage. The push-in terminals have openings (Test) for test probes.
3. If a device cannot establish communication to the myTEM FT Base Modul, check if the CFT bus (C+/C-) is correctly wired and the ground (L / GND) is connected. A missing ground connection can affect the communication.

Applications

• Switching of 4-coloured LED lights
• Dimming of LED lights
• Wiring according to the tree topology. Supply and communication each have four connection points for distribution to other devices. These push-in terminals can be pulled upwards for easy replacement of the device.
• Operation via the central server

Technical Specifications

Note on Fixed Conductors: WARNING! The fixed conductors can be shortened but cannot be replaced. If they are damaged, the device should be discarded.
