Important safety information.

Please read this and other device guides carefully. Failure to follow the recommendations set forth by Aeotec Limited may be dangerous or cause a violation of the law. The manufacturer, importer, distributor, and / or reseller will not be held responsible for any loss or damage resulting from not following any instructions in this guide or in other materials.

Pre-Installation of Nano Dimmer.

Nano Dimmer installs behind a lighting switch or dimmer. It works with both 2-wire and 3-wire (with or without neutral) lighting setups, though each installation of Nano Dimmer is accordingly slightly different:

• First determine if there is a neutral wire present in your gangbox located behind your lighting switch. This will determine if you are wiring under 2-wire or 3-wire.
  • If there is a neutral present, you will follow "Wiring diagram of 3-Wire system" under the section "Install Nano Dimmer"
  • If there is no neutral present, you will follow "Wiring diagram of 2-Wire system" under the section "Install Nano Dimmer"

• Depending on your load size, you may or may not need to install a bypass load if your minimum load does not meet expectations. To determine if you need a Bypass load, determine if your load meets the minimum power requirements. 

• There are some important electrical specifications you will need to know about Nano Dimmer before installing it to your load:

Power input: 120 to 240VAC, 50/60Hz.

Maximum Rated Current Output: 1.2A maximum

Maximum Rated Power Output: 144W maximum.

If your Load (ie. 4x Incandecent bulbs each 40W each = 160W) exceeds 144W maximum load, your Nano Dimmer will automatically turn itself off after a certain amount of time to avoid any damages to it. In this case, it would be best to replace your load with low power bulbs which will help save power, and ensure that you do not bypass the 144W load.

• Last but not least, please note the Nano Dimmers Supported Loads before you continue on to installation:

1. Set your Z-Wave controller into pairing mode

2. Toggle the External Switch once (If using a momentary push button tap the button once), the green LED (basic secure indication) will blink to indicate the Nano Dimmer is entering into pairing mode.

3. If the Nano Dimmer has been successfully added to your Z-Wave network, its RGB LED will be solid. If the pairing was unsuccessful, the red LED will be on for 2 seconds and then remain a colourful gradient, repeat the instructions above from step 1.

Removing Nano Dimmer from a Z-Wave network using the Internal Button.

Your Nano Dimmer can be removed from your Z-Wave network at any time. You’ll need to use your Z-Wave network’s main controller. To set your Z-Wave controller/gateway into removal mode, please refer to the respective section within your controller instruction manual.

1. Set your Z-Wave controller into removal mode.

2. Press the Action Button on the Nano Dimmer.

3. If the Nano Dimmer has been successfully removed from your Z-Wave network, its RGB LED will remain colourful gradient. If the removal was unsuccessful, the RGB LED will still be solid (following the state of the output load), repeat the instructions above from step 1.

Removing your Nano Dimmer to Z-Wave network using the External Switch.

Using this method, you will never have to remove the external switch to get to your Nano Dimmers button to perform an exclusion.

1. Set your Z-Wave controller into removal mode.

2. Toggle the External Switch 2 times within 1 second (If using a momentary push button tap the button 2 times within 1 second).

3. If the Nano Dimmer has been successfully removed from your Z-Wave network, its RGB LED will remain colourful gradient. If the removal was unsuccessful, the RGB LED will still be solid (following the state of the output load), repeat the instructions above from step 1.

Advanced functions. 

Changing mode on the External Switch/Button Control.

The Nano Dimmer can be controlled via 2-state (flip/flop) external/manual switch, momentary push button or the 3-way switch. To automatically detect and set the mode to the appropriate type of manual switch wired into Nano Dimmer, toggle the button on the manual switch once and wait 2 seconds for the Nano Dimmer to detect the type of manual switch.

You can also set the external switch mode through Configuration Command Class. 

Parameter 120 [1 byte] (for S1) and Parameter 121 [1 byte] (for S2) is the parameter that will set one of the 3 different modes. You can set this configuration to:

(0) Unknown Mode

(1) 2-state switch mode

(2) 3-way switch mode

(3) Momentary push button Mode

(4) Enter auto switch detection mode

Touch panel control.

As you can see that the Nano Dimmer’s surface has a pin port, this port is used to connect the Touch panel. When you have already connected it to the Nano Dimmer, you will be possible to control the Nano Dimmer through the Touch panel directly.

Monitoring Energy Consumption.

The Aeotec Nano Dimmer can report wattage energy usage or kWh energy usage to a Z-Wave control point when requested. If this function is supported by the control points, the energy consumption will be displayed in the user interface of the control points. (The specific Z-Wave commands supporting energy monitoring are the Meter Command Class. Automatic reports are sent to association group 1, which is setup via the Association Command Class.) Please consult the operation manual for these control points for specific instructions on monitoring the Nano Dimmer.

Advanced or Basic security feature of your Nano Dimmer in Z-Wave network.

Including Nano Dimmer as a basic secure device:

If you want your Nano Dimmer as a basic secure device in your Z-Wave network, press the Action Button once on Nano Dimmer when you pair it to your gateway. If inclusion is successful, the green LED will be on for 2 seconds, and then return to a solid indication. If inclusion is unsuccessful, the red LED will be on for 2 seconds and then return to a colourful gradient.

Including Nano Dimmer as a advanced secure device:

In order to take full advantage of the Nano Dimmer, you will want your Nano Dimmer as a security device that uses encrypted messages to communicate in your Z-wave network. A security enabled controller/gateway (or Z-Wave Plus controller) is required.

1. Set your Z-Wave Plus controller into pairing mode.

2. Press the Action Button 2 times within 1 second on the Nano Dimmer, the blue LED (advanced secure indication) will blink to indicate the Nano Dimmer is entering into advanced secure pairing mode.

3. If the Nano Dimmer has been successfully added to your Z-Wave network, its RGB LED will be solid. If the pairing was unsuccessful, the red LED will be on for 2 seconds and then remain a colourful gradient, repeat the instructions above from step 1.

Reset your Nano Dimmer.

If at some stage, your primary controller is missing or inoperable, you may wish to reset all of your Nano Dimmer’s settings to their factory defaults. 

To do this, press and hold the Action Button for 20 seconds and then release it. Your Nano Dimmer will now be reset to its original settings, and the green LED will be solid for 2 seconds and then remain the colourful gradient status as a confirmation.

Manually detecting or setting the External Switch over S1 or S2 terminals.

There are actually 2 different methods that you can approach this issue, (1) use your gateway to send in the configuration settings, or (2) manually toggle the internal button of Nano to force it into switch detection mode.

Method 1 - Parameter settings

If you have an understand on how to use your gateway to send in parameter settings, you can refer to the below parameter settings.

Method 2 - Manually forcing Nano to enter switch detection mode for S1 or S2

To force the Nano to enter external switch detection mode again (For S1):

1. Tap the Nano button 4x times within 1-2 seconds which will force Nano to enter External Switch detection mode. (LED will flash blue)
2. Flip your external switch once, then wait at a minimum 10 seconds before you flip the switch again.
3. Now test your external switch.

To force the Nano to enter external switch detection mode again (For S2):

1. Tap the Nano button 6x times within 1-2 seconds which will force Nano to enter External Switch detection mode. (LED will flash green)
2. Flip your external switch once, then wait at a minimum 10 seconds before you flip the switch again.
3. Now test your external switch.

Adjusting dimming range and ramp speed of Nano Dimmer.

You may notice that the dimming ranges over your dimmable LED bulb will vary, and sometimes it may seem that your dimmable LED bulb turns on instantly. You can adjust the range of dim level as well as the speed that the Nano Dimmer ramps up or down.

You may find more information in our article: Adjusting dimming ranges and rate of dim speed with Nano Dimmer.
