Eltako EUD12NPN-BT/300W-230V Universal Dimmer Switch with Bluetooth

Introduction

The Eltako EUD12NPN-BT/300W-230V is a universal dimmer switch featuring integrated timer functionality and Bluetooth connectivity, controllable via the ELTAKO Connect app. It utilizes a Power MOSFET for loads up to 300W and offers automatic lamp detection with a low standby loss of only 0.3 watts.

The device allows for granular control over minimum and maximum brightness, dimming speed, and various specialized functions such as a children's room mode, snooze function, motion detector, and programmable timer/astro functions. Settings can be managed through the app, including time, date, location, and Bluetooth parameters.

It is a modular device designed for DIN EN 60715 TH35 rail mounting, occupying 1 module (18 mm width, 58 mm deep). It is suitable for dimmable 230 V LED lamps and dimmable energy-saving lamps (ESL), with performance dependent on lamp electronics and dimming technology.

Key Features & Operation

The dimmer switch supports soft start and soft OFF functions to protect lamps.

Control & Power:

• Control, supply, and switching voltage: 230 V.
• Integrated timer with up to 10 program memory locations.
• Automatic date and summer/winter time changeover.
• Power reserve without battery: approx. 5 days.

Program Memory Locations: Each location can be configured for the Astro function (automatic switching after sunrise or sunset) or one of 9 other functions: On, Off, On with dimming value (%), On with memory value, light alarm clock, snooze switch, On with residual brightness, Off with residual brightness, or TI (Impulse Generator).

Power Failure Handling: In case of a power failure, the switching position and brightness level are stored and the device resumes operation upon power return.

Protection: Automatic electronic overload protection and over-temperature switch-off.

Manual Control: A front button allows manual switching On/Off. The control input A1 supports universal buttons for pulses. A separate direction button for 'off' can be connected via a diode (RTD), and a direction button for 'on' connects directly to A1. The input A1 can switch between 'direction button' and 'universal button' modes.

Advanced Inputs:

• BM input: For connecting a motion detector.
• ZE and ZA inputs: For central On/Off control with priority, overriding other inputs when active. A green LED indicates activation of one of the four control inputs.

ELTAKO Connect App Integration

The dimmer switch is configured via the ELTAKO Connect app.

Connecting to the App:

• Press the front button for 6 seconds until the blue LED flashes.
• Establish connection via the app (default PIN: 123123).
• The blue LED flashes during pairing readiness and turns solid once connected.
• The connection automatically ends after 3 minutes of inactivity or can be manually ended.
• The app guides users through the setup process.
• Automatic disconnection occurs after 20 minutes of no app interaction.

Bluetooth Reset: Tap the front button 8 times to reset the Bluetooth PIN. ?

App Operation - Basic Settings:

• Local Pushbutton Input (A1): Auto-detects universal or directional pushbuttons.
• Directional Pushbutton: Manual switching via a directional pushbutton.
• Universal Pushbutton: Manual switching via a universal pushbutton.

App Operation - Operating Mode:

• Auto (Default): Short commands switch On/Off; continuous control adjusts brightness to maximum. Interruptions change dimming direction. Central control has priority. Motion detector, light alarm clock, and snooze functions are configurable.

Special Functions & Modes

Motion Detector:

• No Residual Brightness: Turns off when the BM input is inactive and the off-delay expires.
• With Residual Brightness: Remains at a set residual brightness when the BM input is inactive and the off-delay expires.
• Residual Brightness via Switching Program: Configurable residual brightness control within programs.
• Residual Brightness via ZE and ZA: ZE activates with residual brightness, ZA deactivates.
• No Residual Brightness (Semi-Automatic): Turns off only after the BM input is inactive and the off-delay expires.

Light Alarm Clock:

• Activated via a switching program.
• Switches on at low brightness and slowly dims up.
• Duration settable from 1 to 240 minutes.
• Can also be activated by briefly clicking ZE or double-clicking the 'on' universal/directional button (UT/RT).

Snooze Function:

• Activated via a switching program.
• Dims to minimum brightness and switches off. Can be cancelled by briefly pressing the button.
• Duration settable from 1 to 240 minutes.
• Can also be activated by briefly clicking ZA or double-clicking the 'off' universal/directional button (UT/RT).

TI | Impulse Generator: Clock generator with adjustable switch-on/off times (0.1s to 9.9 min) and adjustable maximum brightness (4-100%). Central inputs and BM are inactive.

Relay Function (ER): Switching relay with adjustable brightness (4-100%). Soft on/off duration configurable. Central inputs, BM, and switching programs are inactive.

ESV | Impulse Switch with Off Delay: Adjustable off delay (1-120 min) with optional switch-off warning (0-3 min). Central inputs are active; BM and programs are inactive.

Staircase Timer Switch (TLZ): Switchable switch-off warning, adjustable off delay (1-120 min). Off-delay can be extended by button presses. Permanent light activation possible. ZE and BM inputs start off-delay; ZA input switches off.

MIN Function: Switches to minimum brightness on control voltage application, dims to maximum during the set time, and switches off immediately when voltage is removed. Central inputs active; BM and programs inactive.

MMX Function: Similar to MIN, but dims down to minimum brightness before switching off when voltage is removed.

Dimming Behavior & Curves

Minimum Brightness: Adjustable from 4% to 90% (must be 10% lower than maximum).

Maximum Brightness: Adjustable from 14% to 100% (must be 10% higher than minimum).

Send Brightness: Dims to the current app-set minimum/maximum brightness without altering the memory value, using the app's dimming speed.

Dimming Curves:

• Auto: Suitable for all lamp types. Inductive (wound) transformers can only be used here.
• Leading Edge (LC1-LC3): For dimmable 230 V LED lamps that require specific dimming curves.
• Trailing Edge (LC4-LC6): For dimmable 230 V LED lamps that require specific dimming curves.

Dimming Speed: Settings for overall dimming speed, switch-on speed, and switch-off speed.

Switch-on Behavior:

• Use Memory Value: Resumes the last set dimming value.
• Switch-on Brightness: Lamps can be set to start at a specific brightness before reaching the memory value.
• Switch-on Value: Sets the initial brightness level.

Programs & Channel Settings

Programs: Up to 10 programs can be edited, activated, and deactivated.

Channel Settings: Define actions for 'On', 'Off', 'On with dimming value (%)', 'On with memory value', 'Light alarm clock', 'Snooze', 'On/Off with residual brightness', and 'TI | Impulse generator'. These require specific operating modes to be active.

Active Days: Select days of the week for program execution.

Trigger:

• Time: Set specific switching times.
• Random Mode: Randomly shifts switching times by up to 15 minutes.
• Astro: Automatic switching based on sunrise or sunset, with adjustable time offsets (up to ±2 hours) and solstice influence. Requires correct location setting.
• Time Offset Solstice: Adjusts time offsets for summer/winter time relative to sunset/sunrise.

Device Settings

Device PIN: Manual or automatic setting of date, time, time zone, and summer/winter time.

Location: Manual or automatic entry of location.

Bluetooth: Enable permanent visibility for easier connection. ?

Factory Settings: Options to reset programs, dimming settings, Bluetooth settings, or the entire device.

Technical Data

Notes:

• ¹⁾ For lamps with a maximum of 150 W.
• ²⁾ Max. 2 inductive (wound) transformers of the same type per dimmer. No-load operation on the secondary part is not permitted. No load-switching-off on the secondary part is allowed. Parallel operation of inductive and capacitive transformers is not allowed.
• ³⁾ When calculating load, consider 20% loss for inductive transformers and 5% for lamp load.
• ⁴⁾ Affects maximum switching power.
• ⁵⁾ Applies to dimmable ESL and 230 V LEDs. Lamp electronics may cause limited dimming range, switch-on/off issues, or restrictions on lamp quantity, especially with low loads (e.g., 5 W-LEDs). Leading/trailing edge optimization may limit output to 100 W and is not suitable for inductive transformers.
• ⁶⁾ With loads over 100 W, maintain a ventilation distance of 12 modules to adjacent devices.
