Remote Switch Bricklet¶

Switch 230V devices¶

Switching 230V devices is a typical application. Devices for this come in several forms. For example, as intermediate adapter that goes into your standard socket (e.g. Intertechno ITR-1500 and ELRO HE874) or designed for flush-mounting (e.g. Intertechno ITL-1000). Additional features such as timers to turn off the connected device after a given amount of time are also available.

Switch 12/24V devices¶

Low-voltage or battery powered systems are common in cars, trucks and boats. There are specialized remote switches that operate on 12/24V (e.g. Intertechno CMR-1224).

Dim (energy-saving) light bulbs and LEDs¶

In addition to simple on/off switches there are also dimmers for normal lamps (e.g. Intertechno ITLR-300), for energy-saving lamps (e.g. Intertechno ITL-150) and for LED lamps (e.g. Intertechno ITL-250).

Control Garage Doors and Blinds¶

For garage doors and blinds simple on/off switches are not enough. For this applications there are specialized remote switches that can handle three state up, down and off (e.g. Intertechno CMR-500).

Trigger Gongs¶

Beside switches in different variations there are also gongs (e.g. Intertechno ITR-7000) that can draw attention with sound and/or light signals and are trigger remotely.

Type A: House Code and Receiver Code¶

The house and receiver codes are typically configurable with small DIP-switches inside the remote switch or dimmer. Please note that house and receiver code is sometimes labeled differently. In the following example image the removed cover of the DIP switch is labeled with "System Code" and "Unit Code". "System Code" means house code and with "Unit Code" the receiver code is meant.

In the image below DIP-switches 1 and 5 are on for the house code, this equals 10001 in binary (least-significant bit first) or 17 in decimal. For the receiver code only DIP-switch A is on, this equals 10000 in binary (least-significant bit first) or 1 in decimal.

Type B: Address and Unit¶

Devices of type B do not have switches to configure their address and unit. Instead the remote switch or dimmer has to learn its address and unit. Depending on the specific device at hand it is in learning mode for some seconds after it has been plugged in (left one from Intertechno in the image below) or it has a button that has to be pushed to enter learning mode (right one from ELRO in the image below). While in learning mode you have to send a switch-on command to the device with the address and unit that should be assigned to the device. Maybe it is necessary to send this command several times until the device leaves the learning mode.

Type C: System Code and Device Code¶

The system and device code are typically configurable with code wheels on the back of the remote switch or dimmer. Please note that the system code is sometimes called differently. For example, "House Code", "System Character" or "Family Code".

In the image below the left code wheel (A-P) is set to M for the system code and the right code wheel (1-16) is set to 1 for the device code.
