STC9200 digital temperature controller with dual sensors delivers accurate temperature monitoring and flexible control for refrigeration and storage applications. Dual sensor accuracy: Two included sensors provide reliable readings from 50 to 50 C with 0.1 C resolution, supporting precise climate management. This helps maintain stable temperatures and reduces drift across cooling and storage environments. Comprehensive control modes: Supports refrigeration, defrost, and fan operations, with separate user and administrator menus for flexible and secure system management. Robust and compact construction: Built from grade materials for industrial use, the unit measures 75 x 34.5 x 85 mm and supports an 8 A / 220 VAC output load for consistent performance. Advanced safety features: Includes multiple protection and alarm options along with differential control to help prevent temperature fluctuations and equipment issues. Use scenarios Commercial refrigeration and display: Ideal for grocery, restaurant, and cold storage displays where stable temperatures are critical for perishables and prepared foods. Dual sensors enable monitoring of multiple points within a single unit. Cold storage and pharmaceutical cabinets: Suitable for small to medium cold rooms and medicine cabinets, providing precise control with secure access via separate admin menus and alarms for safer operation. Industrial cooling and processing: Fits control panels for freezers, process chillers, and equipment cooling lines, with defrost and fan control to maintain consistent temperatures and manage frost buildup.
