myTEM SmartHome MTSWI-100-FT FT Switch Dual

The myTEM FT Switch Dual is a universal wall or ceiling switch and is used to control a motor or two electrical devices (ON/OFF). The combined power and energy consumption of the connected devices are measured. The programmable behavior allows flexible use in the house. The device is intended for installation in a flush-mounted box.

Product Description

The myTEM FT Switch Dual is a universal wall or ceiling switch and is used to control a motor or two electrical devices (e.g. roller shutters, window blinds, lamps, fans, etc.) (ON/OFF). The combined power and energy consumption of the connected devices are measured. The programmable behavior allows flexible use in the house. The device is intended for installation in a flush- mounted box, e.g. behind light switches or sockets.

Applications

Switching of lights
Switching of single-phase fan motors
Switching of electric blinds or similar shading devices
Measuring the combined power and energy consumption of connected devices
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.

Functions

Supply voltage 24 VDC with 4-pole push-in support terminals for further wiring. The device is working properly even if the supply voltage drops down to 10 VDC.
Two digital outputs with potential-free relays 6 A, 250 VAC or 30 VDC (Out1 / Out2) with measuring of the current for the combined power and energy consumption.
Up to 50 FT devices can be connected per CFT bus.
CFT bus with free wiring according to the tree topology as indicated in the picture below. The total length of the lines can be up to 500 m.

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.
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 Switch Dual 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. The length of the cables between the device and the load should not exceed 10 m.

CAUTION: Maximum loads shall not exceed 6 A, 250 VAC, (cos(φ) = 1.0).

Please install the device according to the following steps

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.
Connect the device according to the circuit diagram of the myTEM ProgTool or the terminal assignment from the picture below. Use solid wires (Ø0.8 mm) for supply and communication, stripped by 5 to 6 mm. Insert the conductors until they hit the backstop. Connect the 1.0 mm² strands to your loads via terminals, the middle strand being the common input.
Check the wiring and then push the device into the flush-mounted box.
Switch on the mains voltage and include the device with the myTEM ProgTool in the server.
Switch off the mains voltage and fit a cover over the flush-mounted box. When you switch the mains voltage back on again is your device ready?

LED display

The LED next to wires may show the following states:

LED flash-ing green: The device is connected to the FT Base Modul and is in normal operating mode
LED green: The device gets network configurations from the FT Base Modul
LED flash-ing blue: The device is identified using the myTEM ProgTool
LED flashing green and red: The device started and connected to the FT Base Modul but not yet been added to a Smart Server or Radio Server. (Requires an action in myTEM ProgTool.)
LED red: The 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.

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

Quick troubleshooting

The following hints may help solve the trouble

Make sure that the power supply is connected with the correct polarity. With the wrong polarity, the device does not start.
Make sure that the voltage has not dropped below the allowed operating voltage. The push-in terminals have openings (Test) for test probes.
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 (GND) is connected. A missing ground connection can affect communication.
If the power measurement is out of tolerance, the magnetic field of the measurement is affected. This can happen, for example, when the distance to other power lines or the steel in the concrete is very small. In this case, you can adjust the measurement with the myTEM ProgTool.

Configuration

The products can be used immediately after being added to the Smart Home network. However, depending on the function, a configuration may be helpful or required. After setting the parameters, further optional corrections such as offset, etc. are sometimes possible.

CAUTION: Depending on the function, the server may change some settings.
