  Vocabulary
    Electrical Terms * **Line:** This is your hot wire (120V) - also known as your, "live" wire * **Wiring Color:** Black (however, sometimes it can be white/black or red/black) * **Load:** This is the wire that runs from your light switch to what you're controlling (ie: bulb(s), exhaust fan, etc) * **Wiring Color:** Black (however, sometimes it can be white) * **NOTE:** A load can be made up of multiple bulbs or fixtures -- what's important is to understand what turns on and off when you flip your switch. * **Neutral:** This is the wire that carries current back to the power source. * **Wiring Color:** White (or sometimes gray) * **NOTE:** You may not have this wire in your house -- if you do have them, they are often clumped together at the back of your gang-box * **Ground:** This is the wire that provides a path directly to ground (earth) should the current need it * **Wiring Color:** Green or copper
    Wiring Type Terms **NOTE:** In all cases below, when we say, "load", it can be one bulb, multiple bulbs, etc -- think of it as, "whatever turns off when you flip a switch" * **Single-Pole:** One switch controlling one load * **3-Way:** Two switches controlling the same load * **4-Way:** Three switches controlling the same load * **5-Way:** Four switches controlling the same load * **Multi-Way:** For simplicity sake, we will use this term when referring to 3-Way, 4-Way, or 5-Way setups as the switch is programmed the same regardless
    Switch Layout Terms * **Dumb Switch:** Refers to your existing switch (ie: the switches you had before replacing with a smart switch) * **Aux Switch:** Refers to the Inovelli Aux Switch [INSERT HYPERLINK TO PRODUCT PAGE] or the GE, Honeywell, or HomeSeer versions (sometimes these are also called an, "add-on" switch) * **Neutral Setup:** Refers to having a neutral wire present in your wiring setup * **Non-Neutral Setup:** Refers to not having a neutral wire present in your wiring setup
--
Step 1 - Determining Wiring Type The first step is to determine how many switches control your load(s) (aka: lights(s)).

Using the above diagram, please determine what your wiring type is and remember this selection:

  • Single-Pole: One switch controls one load (load may contain more than one light, fan, etc).
  • Multi-Way: Two or more switches control one load (load may contain more than one light, fan, etc). We will use the term, “multi-way” instead of 3-Way, 4-Way, 5-Way, etc as the programming of the switch is the same regardless

REMEMBER/CIRCLE: Single Pole or Multi-Way

Step 2 - Determining Switch Layout **NOTE:** If you determined in Step #1 that your switch is single-pole, you can skip this step and move to Step #3. This step is for multi-way setups only.

Using the diagram above, please determine what your wiring layout is and remember this selection:

  • Smart Switch + Dumb Switch: One smart switch and one dumb/existing switch (one already in your wall).
  • Smart Switch + Aux Switch: One smart switch and one aux/add-on switch (special switch designed by Inovelli).
  • Smart Switch + Smart Switch: Two smart switches

REMEMBER/CIRCLE: Multi-Way (Dumb), Multi-Way (Aux) or Multi-Way (Smart)

Step 3 - Determining AC Power Type In this step, we will determine if you have a neutral wire, which is typically white or not in your switch gang-box. The picture below illustrates what a neutral wire typically looks like.

Other signs you may have a neutral wire include:

  • If your house was built in the mid-1980’s or later
  • If there is an outlet (receptacle) near the switch
  • If switches are in the same gang-box (regardless of the year your house was built)

REMEMBER/CIRCLE: Neutral Wire or No Neutral Wire

Step 4 - Check for Compatibility In this step, we will determine if your switch can be installed with your current setup. If not, you can see some alternate solutions on how to accomplish compatibility.

Taking the answers you remembered/circled in Steps 1-3, please see the chart below to see if your switch is compatible with your setup.

Example: If you circled, “Multi-Way”, “Multi-Way (Dumb)” and “Neutral Wire”, you will see that your wiring is compatible. However, if you circled, “Multi-Way”, “Multi-Way (Dumb)” and “No Neutral Wire”, you will see that your wiring is not compatible and you will need to purchase an auxiliary switch.

IMPORTANT: For installations where no neutral wire is present, depending on the load wattage, you may need to install a special bypass to prevent flickering and/or keep your switch powered. Bypasses can be purchased here: Aeotec Bypass

Step 5 - Selecting Your Schematic The last step is to install your switch. After you’ve determined your wiring type, switch layout, AC Power type and whether or not you have a compatible setup, it’s time to look at the wiring schematics and install your switch.

Using the answers you remembered/circled above, please do the following:

  • Navigate to the Wiring Schematics section
  • Select from the drop-downs your Wiring Type (Single-Pole or Multi-Way)
  • Select from the drop-downs your Switch Layout (Dumb, Aux, Smart)
  • Select from the drop-downs your AC Power Type (Neutral or Non-Neutral)
  • Look at the before schematic that best matches your current wiring (NOTE: Take a picture of your wiring before removing your old switch(es) in case you get confused)
  • Start the Installation Process (remember to turn off the power)
