Auxiliary Switch Make Three-Way or Multi-Way Connections

The Auxiliary Switch can be used with any HAI Lighting Control (HLC) Switch to make "three-way" (two switches control one light) and multi-way (more than two switches control one light) using conventional "three-way" wiring techniques.

HLC Products work as stand-alone or with a Home Control System.

Switch Operation

The Auxiliary switch has a Decora-style rocker switch that may be used to control the lighting load as follows:

Rocker Event

Top Rocker

Bottom Rocker

Double-Tap Snaps the light to fully on Snaps the light to fully off
Hold Starts brightening the light towards fully on Starts dimming the light towards fully off
Release Stops brightening the light Stops dimming the light

Switch LED

The Auxiliary switch comes equipped with a multi-color LED indicator that may be set to off, blue, red, or magenta, depending on how the switch is wired.

If the switch is wired to use the LED, it will always remain on with the hard-wired color, regardless if switch is on or off.

This switch comes with a default white paddle, connectors, and instructions.

Switch Color Change Kits (HAI Part Number 35A14-color codeCS) are available in White (WH), Ivory (IV), Almond (AL), Light Almond (LTA), Brown (BR), Grey (GR), and Black (BL) colors. They are sold in case lots of 12 only.

About HAI Lighting Control (HLC)

An HAI home control system has the ability to change your light settings by the time of day, a set schedule, by the triggering of events (including motion), via a telephone call, Touchscreen, Smartphone, or by a computer connected to the Internet.

All HLC products, including this Auxiliary Switch, are UL Listed.

Easier to Install

HAI Auxiliary switches have been engineered with less depth than competitor products; consequently, HAI Auxiliary switches are easier to install.



Configuration Software

When used with an HAI Home Control System HLC products automatically configure themselves, and outside software is not required. HAI offers HAI UPB™ UPStart Configuration software for professionals who desire to make advanced changes to HAI's default setup.

Requirements / Recommendations

  • The Auxiliary Switch requires a neutral (white) connection wire.

  • If you are using an HAI home control system with HLC switches, you must install a UPB™ PIM.

  • HAI recommends that every HAI Lighting Control (HLC) installation include a Phase Coupler.

  • To use the HAI Upstart Configuration software you must install a UPB™ PIM and use a UPB™ PIM to computer cable to connect it to a computer.
