Lutron Sunnata RF Switch HRST-8ANS Installation and Wiring Guide

Introduction

This document provides installation instructions for the Lutron Sunnata RF Switch (HRST-8ANS) and its companion switch (HRST-RS). It covers wiring configurations, operation, setup, and troubleshooting for smart home lighting control systems.

Please read all instructions before installing.

Step 1: Turn Power OFF at Circuit Breaker

⚠️ WARNING: ELECTRIC SHOCK HAZARD. May result in Serious Injury or Death. Turn off power at circuit breaker or fuse before installing.

Ensure the circuit breaker controlling the power to the installation area is in the OFF position.

Step 2: Load Types and Derating

This section details the maximum allowable load for the switch based on the type of lighting or motor being controlled and the gang configuration of the installation.

* Minimum load is for Incandescent (INC), Magnetic Low Voltage (MLV), Electronic Low Voltage (ELV), and Fluorescent lighting. LED lighting minimum load is a single LED bulb.

Switch Load Type: HRST-8ANS is designed for use with permanently installed 120 V~ incandescent, magnetic low-voltage, electronic low-voltage, or fluorescent loads and with motor loads up to 1/4 HP (5.8 A).

Companion Switch: HRST-RS is designed for use with Lutron 120 V~ electronic switches.

Note: HRST-8ANS controls have fins that need to be removed for multigang installations.

Step 3: Determine Wiring Configuration

This section outlines different wiring scenarios based on the number of locations controlling the lights.

3A: For lights switched from one location

Diagram Description:

The diagram shows the HRST-8ANS switch. It has terminals for Line/Hot (Black wire), Load/Light (Blue wire), Neutral (Silver wire), and Ground (Green wire). The wiring involves connecting the incoming Line/Hot wire to the switch's Line/Hot terminal, the Load/Light wire to the switch's Load terminal, the Neutral wire to the switch's Neutral terminal, and the Ground wire to the switch's Ground terminal.

Wire Connection Methods:

Fully wrap wires around the screw terminals and tighten, or strip insulated wires to 1/2 in (13 mm) and insert into the push-in terminals. Solid copper wire only.

Torque Specification: 5 in-lbs (0.55 N•m)

Wire Gauge: 12/14 AWG (2.5-1.5 mm²)

3B: For lights switched from two locations

Diagram Description:

This configuration uses one HRST-8ANS switch and one HRST-RS companion switch. The HRST-8ANS is connected to the Line/Hot and Load. The HRST-RS is connected to the Load and acts as a traveler. The diagram shows the HRST-8ANS with terminals for Line/Hot, Load, Neutral, and Ground. The HRST-RS has terminals for Load, Traveler (often marked or a specific color), and Ground. The diagram emphasizes that the HRST-8ANS must be on the load side and the HRST-RS acts as the companion switch.

Important Note: Tag or mark the common wire on both existing devices. This is usually connected to a darker (or different) colored screw than the others. This does NOT include the ground screw.

Note: Only one switch can be used per circuit. The HRST-8ANS must be wired on the load side. Connect Neutral to the switch. Up to four companion switches may be used.

3C: For lights switched from three or more locations

Diagram Description:

This configuration involves one HRST-8ANS switch and multiple HRST-RS companion switches (up to four). The HRST-8ANS is connected to Line/Hot and Load. The HRST-RS switches act as travelers between each other and the main switch. The diagrams show the HRST-8ANS and multiple HRST-RS units, illustrating the flow of power and traveler wires. The primary switch (HRST-8ANS) is always on the load side, and companion switches (HRST-RS) are wired in series with traveler wires.

Important Note: Tag or mark the common wire on existing 3-way devices. This is usually connected to a darker (or different) colored screw than the others. This does NOT include the ground screw.

Note: Only one switch can be used per circuit. The HRST-8ANS must be wired on the load side. Connect Neutral to the switch. Up to four companion switches may be used.

Step 4: Mount all devices using the provided screws and attach wallplate

Securely mount the switches and companion switches into the wallbox using the provided screws. Then, attach the wallplate.

Step 5: Turn Power ON at Circuit Breaker

After all wiring is complete and devices are mounted, turn the circuit breaker back ON to restore power.

Step 6: Operation

ON (Lights or load turns on):

• Lights or load turns on.
• Refer to Sunnata MyLevel Personalization Application Note #734 (P/N 048734) to change the appearance of the light bar.

OFF (Lights or load turns off):

• Lights or load turns off.

FASS (Front Accessible Service Switch):

This feature allows for serviceability. Pull the tab out to change the room's light bulb.

Step 7: Setup

Setup for use WITH a system (e.g., HomeWorks)

For use in a HomeWorks system, please refer to the Getting Started Guide: www.lutron.com/HWsupport

For reliable performance in a system, this device should be placed within 25 ft (7.6 m) of two additional compatible HomeWorks Sunnata dimmer, switch, keypad, or HomeWorks processor wireless devices. For more information, please refer to the Wireless Setup guide: www.lutron.com/HWsupport
