S1 - Smart Heat Trace Controller

The S1 is a single-circuit IoT heat trace controller for use in snow melting, freeze protection and temperature maintenance applications. The device can drive up to a 30A resistive load to control electric heat trace systems operating between 110 VAC and 277 VAC. The S1 comes in an outdoor rated enclosure tested to IP67 standard.

WiFi/Ethernet

The S1-A supports both WiFi or ethernet connections. The device is designed to use 802.11n Wi-Fi operating in the 2.4GHz band or the 5GHz band. It is also compatible with older 2.4GHz 802.11b, 802.11g, and 802.11a networks. The ethernet connection supports 10Mbps and 100Mbps operation.

Control Modes

Freeze Protection

Smart freeze protection uses feedback from the heater and weather forecast to ensure the system only operates when needed. Connect a temperature sensor for a foolproof offline fallback option on critical systems.

Snow Melting

Smart snow melting uses weather data to activate the heating system, includes optional preheating, the ability to ignore light storms, and dynamic heating after the storm, all to improve overall system performance and reduce energy use and operating cost. Frio’s proprietary algorithms let you chose between a variety of snow melting systems from gutters, to roof edges, to heated driveways.

Temperature Maintenance

Connect a temperature sensor or use smart control based on heater feedback. For high precision systems, using smart control with a temperature sensor will give you the best results.
