Isotherm SED00036DA – Intelligent Temperature Control (ITC) Digital Display Kit for 101N212/101N510

Isotherm SED00036DA – Intelligent Temperature Control (ITC) Digital Display Kit for 101N212 / 101N510

The Isotherm SED00036DA Intelligent Temperature Control (ITC) Kit is an advanced digital interface designed for marine refrigerators equipped with Secop electronic boards 101N212 (BD35/50F) and 101N510. The system enables precise external temperature regulation, status monitoring, and optimized compressor performance, significantly reducing onboard power consumption. Using a dedicated air sensor inside the cabinet, the ITC module continuously analyzes cooling demand and adjusts compressor RPM through proprietary microprocessor algorithms to maximize efficiency and power savings.

The unit supports overcooling modes to store cold energy in food and beverages during periods of surplus charging (shore power, alternator, AC/DC kit), reducing battery load later. Three selectable battery-protection levels, Eco mode, Boost mode, and soft-start function further enhance system control and longevity. The digital panel may be wall- or flush-mounted and serves as a complete retrofit solution for upgrading legacy Isotherm refrigerators to smart, energy-optimized operation.

Technical Specifications

Main Features
