7 Start up

7.1 Simple operating functions on the device

There is one control button per channel on the devices (one UP button and one DOWN button for the blind actuator). You can operate the actuator immediately (teaching is not required) and check for correct electrical installation. With switching and dimming actuators, you can use it to switch the channel on and off. With blind actuators, you can move the hangings up or down.

Only the brief button press is used for operation. The longer button press (holding longer than 4 seconds) switches the actuator to teach mode.

7.2 Teaching-in

Please read this section completely before starting with any teaching-in!

Teaching-in requires that both devices to be connected are put into teach mode and the desired channel must be selected for training.

The surface-mount actuators have no special teach button. Teaching a certain actuator channel requires pressing and holding the respective channel button (one of the two buttons ▲ or ▼ for the blind actuators).

Teach mode is indicated by the device LED flashing continuously.

If no teaching occurs, teach mode is automatically ended after 20 seconds. If other devices are in teach mode, these are taught.

8 Operation

After teaching, simple operating functions are available using the taught control elements.

8.1 Switching actuator

Depending on the control elements that have been taught, the switch actuator can be controlled in two button ON/OFF mode or in toggle mode.

8.2 Blind actuator

Depending on the control elements that have been taught, the blind actuator can be controlled in two button UP/DOWN mode or in toggle mode (UP/STOP/DOWN/STOP).

8.3 Dimming actuator

Depending on the learned operating element, the dimmer can be used in two button ON/OFF operation or in toggle operation ON/OFF with a brief press on the button and brighten/dim with a longer press of the button.

9 Resetting to the initial state

In order to reset the actuator to factory status, switch the device to teach mode with the (first) channel button

(hold button pressed for at least 4 seconds).

If the device is in teach mode, hold the (first) channel button pressed down for at least 4 seconds. The actuator reset is indicated by the device LED flashing quickly.

10 Device LED feedback

10.1 Flash codes

Different actuator states are indicated by the channel LED/channel LEDs flashing:

Slow flashing Teach mode
Fast flashing Reset
One long, x-short (depends on the type of error)	Error

10.2 Operational status display

As soon as the relay for a channel (or a direction for the blind actuator) is triggered, the respective channel LED will be illuminated continuously.

After configuring the actuator with the center or a programming tool, the device LED indicates other device states besides those described. More relevant information is provided in the configuration instructions for the devices and in the system manual.

11 Behavior after power restoration

After switching the operating voltage on (mains voltage returned), the actuator checks the respective components. If an error is detected, it is indicated by all channel LEDs flashing (the LEDs for both directions flash for the blind actuator). This is repeated continually and the device starts to work with the respective functionality.

If the test runs without any errors, the actuator sends a radio telegram with the respective status information.

The actuator waits a random delay time before sending so that all actuators are not sending at the same time when the power returns (after a power outage or shut-down).

During this time, the channel LEDs flash (like in teach mode). If the delay time is short, the flashing may not even be noticeable.

12 Maintenance and cleaning

This product is maintenance-free. Repairs are only to be done by trained professionals.

Dimming actuator

The device is provided with two internal device fuses for protecting the triac from greater current loads. If the device becomes overloaded and a fuse is blown, it can be replaced by a technician!

Disconnect the mains power before removing the device (switch the circuit breaker off)! Work on the 230V network is only permitted by qualified electricians (in accordance with VDE 0100).

Replace fuses with same type fuses (microfuse 5 x 20 mm, 2.5 A slow)!

13 Other notes on operation

Applicable for HM-LC-Dim2T-SM: If the device reaches too high a temperature during operation (due

to insufficient air circulation at high load, for example), the load will first of all be reduced by lowering the brightness. If the overtemperature persists, the load will be disconnected.

If the actuator is operating via the HomeMatic central control unit (CCU), please note that the central control unit will not be informed in the event of a load failure.
