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.


Warning: Risk of electrical shock. The main circuit breaker or fuse must be shut off during installation. A licensed electrician with knowledge and understanding of electrical systems and safety should complete the installation.

Nano Dimmer current can not exceed 1.2 amps. Its maximum rated power output is 144 watts for 110 volt models, and 278 watts for 220-240 volt models and comparable.



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. 


Installation Type
Minimum load power requirement.
3-wire Installation with Neutral Wire
10W
2-wire Installation without Neutral Wire
20W


  • 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:

Control ability
Supported load types
With dimming function (On/Off/Dim control)
Incandescent bulbs, Halogen bulbs with or without electronic transformer, Dimmable LED bulbs (leading edge and trailing edge), Dimmable Fluorescent lamps.
Without dimming function (On/Off control only)

Note: The “N” terminal should be connected to the “L” terminal when the Nano Dimmer is installed by 2-Wire system.


Installing a Bypass Load.


You may need to connect a small power load (E.g. a LED light or a compact fluorescent lamp) to be controlled. In this case, the Nano Dimmer may not get enough power from the AC power supply, so a bypass can be added to act as a dummy load to keep your Nano Dimmer get enough power from the power supply. It can also keep your light from flickering when diming off the light.
