1 Introduction
Before you start with the installation of the Dual Dimmer 1 and put the device into operation, please read these
installation and operating instructions carefully until the end, especially the section of the safety instructions.
2 Product Description
With the Dual Dimmer 1 you can dim and switch lamps very gently.
The brightness of the connected lamps can be controlled or switched on/off by the push-button dimmer function in
the living room (extension input), by push-buttons on the top of the module and electronically via the 1-wire
interface. Any buttons from all switch ranges can be used for the push-button dimmer function. The dimmer
behavior is always very soft and pleasant.
You can change the brightness by pressing the living area buttons for a long time and switch on/off by briefly
pressing the button.
The touch dimmer function works with 12V or 24V DC voltage, which does not give off any disturbance in the
living room. This makes the Dual Dimmer 1 ideal for low-radiation areas such as bedrooms and living rooms.
The ESERA manual control allows you to operate the lighting reliably. Everything functions as in a "normal
house", even without Smart Home control or software.
The 1-Wire Bus interface is available for integration into your Smart Home control system.
* When installed in distribution cabinets with low heat dissipation, e.g. installed in wooden or (RI) plaster walls, the connected
load must be reduced by 25%, also when the ambient temperature rises above 25°C.

This dimmer can switch and dim both dimmable LED luminaires, ohmic (e.g. incandescent lamps, HV-halogen)
and inductive (e.g. LV-halogen with transformer or fans) loads with corresponding power. Low-voltage halogen
lamps may only be operated in conjunction with a wound transformer.
For the living room touch dimmer function, it is sufficient to supply the dual dimmer 1 with the 1-wire bus voltage
(12V). This enables a "Smart Home Ready" installation in your building or apartment. This also ensures extremely
high reliability, as the lighting functions when the Smart Home control is not yet programmed or has failed.
3 Auto-E-Connect® Support
The ESERA Auto-E-Connect® 1-Wire Plug and Play system will be used for the
1-Wire Bus supported. This enables fully automatic configurations of 1-Wire sensors
and actuators on the 1-Wire bus. It is optimized for industrial applications and
enables significant added value beyond the sensor and chip data.
The Auto-E-Connect function automatically recognizes ESERA chips, sensors and actuators, starts suitable
libraries and outputs fully formatted data.
The Auto-E-Connect functionality will be available from mid 2020 via 1-Wire Controllers, 1-Wire Gateways and
1-Wire ECO from ESERA available.
Further information on ESERA Auto-E-Connect can be found on the ESERA website, ESERA Config-Tool 3, or in
the download area for this article in the ESERA Webshop.

Note on the detection of suitable and unsuitable transformers
For wound transformers, a commercially available resistance meter (multimeter) can be used to measure the
Transformer resistance (power 20-250W) with less than 50 Ohm between L and N can be measured.
With electronic transformers of comparable power, you can usually achieve resistance values of greater than
Measure 100,000 Ohm between L and N.
These electronic transformers are not suitable for the dual dimmer 1 (phase angle control).
An already wired electronic transformer must always be disconnected from the mains on the 230 V and
low-voltage side. The circuit must be disconnected (see safety instructions).
Make the connection according to one of the following circuit diagrams. The cables to be connected
should be stripped approx. 12 mm.

8 Operating mode, display and operation
The Dual Dimmer 1 has two operating modes, normal mode and submenu.
The behavior of the dimmer can be changed via the submenu.
8.1 Normal operation
After commissioning, the device is in normal operation. The two dimmer channels can be controlled via the
buttons on the top of the module, the external binary inputs or via the 1-wire interface.
The current dimmer values are shown on the LED display in 25% steps.
8.2 Submenu for dimmer behavior
If you press both buttons on the top of the module simultaneously for 3 seconds, the module switches to the
submenu where you can change the dimmer behavior.
If the dual dimmer 1 is in this menu, the status LED flashes continuously fast. The selected menu option is
animated by the upper row of LEDs.
If you do not use a button for 3 seconds, the Dual Dimmer 1 automatically switches to normal operation.
Functions of the module buttons in the submenu
Button 1: Select mode (currently the Dual Dimmer 1 has two modes to choose from)
Button 2: Mode on/off.
Mode 1 (LED 25%): dimmer on/off hard or soft
Mode 1 can be used to select how the dimmer behavior is to behave on a short keystroke (output on/off).
You can choose between soft and hard.
Mode 2 (LED 50%): dimmer on/off, 0/100% or 0/last dimmer value
Mode 2 can be used to select whether the dimmer value changes to 100% or to the last stored value after
briefly pressing the button.
9 Brightness control Dimmer
The dimmer channels can be controlled directly via the two buttons on the top of the module.
With a short push of a button the corresponding output is switched on or off.
A long press of the button makes the brightness brighter or darker.
The current dimmer value is shown on the LED display on the top of the module in 25% steps.

10 Pushbutton interface
In addition to the manual control (module top) and the 1-wire interface, the Dual Dimmer 1 also has an 8-fold
pushbutton interface (8 x binary input) for switching and dimming the outputs.
To switch an output, a short input signal (keystroke) is sufficient, to dim a long input signal to the corresponding
input.
The inputs of the 8-fold pushbutton interface (extension inputs) are intended for switching and dimming luminaires
or luminaire groups in commercial and residential areas. The inputs are controlled with a typical 24V (10-30V) DC
voltage. Pushbuttons from any switch manufacturer can be used on the inputs. Any number of push-buttons can
be connected in parallel at each input of the push-button interface.
The direct control of the Dual Dimmer 1 via pushbutton interface ensures very fast switching and dimming
even without a Smart Home System (software).
In addition to pushbuttons, another pulse control signal can also be used to switch and dim the outputs of the
Dual Dimmer 1.
All three interfaces, module push-button, pushbutton interface and 1-wire interface, work in parallel on the
outputs. An output switched e.g. by the 1-Wire interface can be switched off or on and dimmed manually or via
pushbutton interface.
11 Software / Control
The 1-Wire interface of the Dual Dimmer 1 is controlled by standard commands for the DS2408 module.
The 1-Wire interface can be used to read back every keystroke as well as the dimmer values of the outputs. The
dimmer values are output alternately via the 1-wire interface. Channel 2 can be detected by bit 5 (1).
The outputs of the dual dimmer 1 are controlled as follows via the 1-wire interface by byte command:
One output can be controlled per transmitted byte value.
- Bits 0-4 corresponds to the brightness value (32 dimmer levels)
- Bit 5 is reserved, currently no function
- Bit 6 is intended for the selection of the dimmer output.
Channel 1 is addressed with a 0, channel 2 with a 1.
- Bit 7 is reserved, currently no function
11.1 Control via 1-Wire Controller / 1-Wire Gateway
The control and data output of the Dual Dimmer 1 is very simplified via the 1-Wire Controller / 1-Wire Gateway.
The current dimmer values and the status of the push-button interface are output continuously.
In the case of a control signal on the push-button interface or on the top of the module, a separate data record
with the normal formatting is output. The following control command can be used to control the dimmer value of
one output at a time. There are 32 dimmer values available per output.
11.2 Control Command for Dual Dimmer 1
One output of the Dual Dimmer 1 is controlled per command. To control the dimmer outputs, the following options
are available
32 dimmer stages (0-31) per channel available.
Command: SET,OWD,DIM,OWD-number, output, dimmer value
Example: set,owd,dim,2,1,25 => OWD number 2, output 1 is set to dimmer value 25.
After controlling the dimmer, the new dimmer value is output as confirmation.
11.3 Data Output 1-Wire Controller / 1-Wire Gateway
For the Dual Dimmer 1 the following data for push-button interface and outputs are output.
The input and output values are output as decimal values 0-254 and in a second data set binary with 0 and 1.
Each input and output has a value which is summed up.
