Product Description:

The SunTouch SunStat ConnectPlus Wi-Fi Programmable Thermostat is a premium smart thermostat designed for electric radiant floor heating systems. Engineered by Watts, a global leader in heating and plumbing solutions, this innovative control allows homeowners to manage floor warmth remotely while maximizing comfort and efficiency. With Wi-Fi connectivity, the ConnectPlus integrates seamlessly with the Watts Home app, giving users complete access to system settings, scheduling, and real-time energy reports from any smartphone or tablet.

This Wi-Fi programmable thermostat automatically synchronizes with internet-based time servers for precise clock updates and displays current outdoor temperatures and weather forecasts directly on the touchscreen interface. Its outdoor temperature compensation and warm weather shut-down functions help conserve energy by reducing heating output when external conditions do not require additional warmth.

Compatible with Amazon Alexa and Hey Google, this thermostat offers convenient voice control for adjusting temperatures and modes without manual input. The 4.3-inch full-color digital touchscreen provides intuitive control and visual clarity, with multiple screen layout options and flexible mounting—perfect for modern homes, condos, and commercial spaces.

Advanced features include energy-usage monitoring, customizable alerts via email or text, and compatibility with optional SunStat Relay R4 modules to expand control to multiple heating zones. The thermostat operates using 915MHz wireless technology, ensuring strong connectivity between the controller and linked components. It also offers second-stage heating, ammeter diagnostics, and a help screen for quick troubleshooting.
