This operating manual provides a complete overview of the S1 IoT Heat Trace Controller, including an installation
guide and all relevant information required to use the controller. The Frio S1 shall only be used for the purposes
described in this manual and must be installed by a trained service professional in compliance with all applicable local
electrical codes, according to the instructions contained herein. For more information, including device terms and
conditions and limited warranty information, please visit www.frio.co.

O
VERVIEW
The S1 is a single-circuit IoT heat trace controller for 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
100 VAC and 277 VAC. The S1 comes in an outdoor-rated enclosure tested to IP67 standards.
Wi-Fi, Ethernet, and Cellular (available on the S1-C) capability allow the S1 to connect to the Frio cloud platform via
the internet, enabling smart, cloud-based control. When connected to the cloud, the S1 will upload system status and
receive operational commands. The Frio cloud platform integrates weather data, system feedback, and proprietary
control algorithms to automatically maximize system effectiveness and efficiency. Multiple S1 devices can be joined
together in the Frio cloud platform, allowing centralized control of multiple heat tracing systems.
The cloud connection enables advanced monitoring and notification of your heating system. Data on key performance
characteristics are monitored over time, and anomalies or excursions are flagged and reported. The Frio cloud
platform offers customizable SMS and email notifications so that the user can be alerted immediately if there are any
issues with the system. Users can access their S1 device remotely via the Frio cloud platform to check status, activate
the system, or run a diagnostic test, eliminating the need to physically check the heater control system. If an internet
connection is not available, the S1 can operate in an offline configuration.
