Product Description:
The SunTouch SunStat Relay R4 is a high-capacity load control relay designed to safely manage electric radiant floor heating systems that exceed 15 amps. Manufactured by SunTouch, this advanced relay allows SunStat thermostats to control larger heating zones by offloading electrical demand while maintaining precise temperature regulation and system reliability.
Engineered for dual-voltage operation at 120V or 240V, the SunStat Relay R4 connects directly to compatible SunStat thermostats and regulates power delivery to SunTouch electric floor heating cables and mats. It supports both wired and wireless communication, featuring built-in 915 MHz wireless technology for seamless pairing with the SunStat ConnectPlus thermostat, while also offering a wired connection option for Connect and Command thermostats.
This relay is ideal for large residential and commercial underfloor heating installations where higher amperage loads are required. A single wired ConnectPlus thermostat can control up to 10 SunStat Relay R4 units, while wireless systems can support up to 6 relays. When combined, these relays can manage heating coverage of up to 1650 square feet at 120 VAC or up to 3300 square feet at 240 VAC, making the system scalable for expansive floor warming applications.
Each SunStat Relay R4 requires its own dedicated 20-amp circuit and individual circuit breaker to ensure safe operation and compliance with electrical codes. The unit includes a built-in GFCI for enhanced electrical protection, along with clear status indicator lights that provide real-time system feedback for installers and homeowners.
When paired with the SunStat ConnectPlus thermostat, users gain Wi-Fi connectivity and remote system monitoring through the free Watt Home app, available for both Apple iOS and Android devices. The ConnectPlus system also supports smart home integration, allowing voice control of the floor heating system through Alexa and Google Assistant. For Command and Connect thermostats, the Relay R4 op
