US 2026/0086536 A1 · SYSTEMS AND METHODS FOR A VIRTUAL ELECTRIC HEAT TRACE CONTROLLER

Abstract

An electric heat trace (EHT) control system and corresponding methods are provided. The system comprises a heat trace cable to heat a surface, a sensor that outputs a status value, and an EHT controller in communication with the heat trace cable and the sensor. The EHT controller receives the status value from the sensor, compares the status value to a first threshold, and outputs the status value and a first alarm flag when the status value meets the first threshold. The system further comprises a gateway in communication with the EHT controller. The gateway receives the output status value and the first alarm flag when output from the EHT controller, compares the status value to a second threshold, and communicates a second alarm flag to a management system in communication with the gateway when the status value meets the second threshold.
