The HZ2‑AUX Horizon® 2 in‑wall multiway remote controls Horizon 2 dimmers and switches. Its design matches the entire line of Horizon 2 dimmers, switches, and keypads, making it a great addition to new or retrofit installations.
Note: The HZ2‑AUX only accepts the style 6 button assembly (large rocker) and does not have an LED backlight. For multiway control using a device that accepts any style button assembly and has LED backlighting, use an HZ2‑KPEX.
The HZ2‑AUX is available with default engraving or custom engraving on a rocker button assembly (Style 6).
- Default engraving on a rocker button assembly (Style 6) is provided with the HZ2‑AUX‑A, HZ2‑AUX‑W, HZ2‑AUX‑B, HZ2‑AUX‑GLASS‑W, HZ2‑AUX‑GLASS‑B, HZ2‑AUX‑BR‑BLK, HZ2‑AUX‑BR‑BRASS, HZ2‑AUX‑DRK‑BRZ, and HZ2‑AUX‑DRK‑NKL. The default engraving includes a simple dot to provide feedback and indicate where the button can be pressed.
- Custom engraving on a rocker button assembly (Style 6) provided with the HZ2‑AUX‑A ENGRAVED, HZ2‑AUX‑W ENGRAVED, HZ2‑AUX‑B ENGRAVED, HZ2‑AUX‑GLASS‑W ENGRAVED, HZ2‑AUX‑GLASS‑B ENGRAVED, HZ2‑AUX‑BR‑BLK‑ENGRAVED, HZ2‑AUX‑BR‑BRASS‑ENGRAVED, HZ2‑AUX‑DRK‑BRZ‑ENGRAVED, and HZ2‑AUX‑DRK‑NKL‑ENGRAVED.
NOTE: Faceplates are not included. Refer to the HZ2‑FP‑G series faceplates for more information.
Button Engraving
Each button on the assembly can be labeled with a custom laser-etched engraving to indicate its specific function. Engraving is included with ENGRAVED models. Textured button assemblies without engraving (BLANK models) are also available and can be used as is or can be custom engraved by a third-party engraver.
Note: Glass and metal buttons can only be engraved by Crestron and are not offered blank.
When a custom engraved model is ordered, the completed engraved button assembly is installed on the device before it is shipped. Engraving files must be provided at time of order and can be created using Impress Custom Engraving Software, the Crestron Home® Setup app, the Crestron Home Online Configurator, or D3Pro® software. If necessary, custom engraving can be changed until the order is processed by emailing orders@crestron.com with the updated engraving file and order information.
To order replacement engravings, refer to the HZ2-BTNS ENGRAVED button assembly product page.
Multiway Dimming and Switching
Similar to traditional three‑ or four‑way circuits, the HZ2‑AUX lets you control the lights from multiple locations using the traveler wire. Up to four devices can be connected to a single dimmer or switch. The HZ2-KPEX provides button backlights and six different engravable button assembly options while the HZ2-AUX provides no button backlight and only accomodates a single large rocker button assembly (Style 6).The multiway controller provides instant usability upon installation without the need for programming.
Note: The HZ2‑AUX cannot be used to control a load directly. It must be used in conjunction with a HZ2‑DIMEX, HZ2‑DIMUEX, and HZ2‑SWEX, (all sold separately).
Multigang Expansion
Install up to four Horizon® 2 devices side‑by‑side in a US multigang electrical box with a compatible HZ2‑FP‑G series faceplate. When multiple devices are installed in a 2-, 3-, or 4-gang faceplate, the buttons on the devices are aligned to form one continuous control surface.

Field-Replaceable Button Assemblies
Field-replaceable button assemblies allow for changes in device function or for the customer to use the system before finalizing the engravings. The button assembly can be replaced with a custom engraved or blank Style 6 HZ2-BTNS button assembly. All Horizon 2 devices can use textured, glass, or metal finishes.
