The SH3B23 is an intelligent small-size temperature controller designed by Weite for low temperature bottle coolers, ice cream display cabinets, frozen refrigerated cabinets and food service equipment. Featuring high-precision PTC/NTC temperature sensors, it accurately monitors and controls cabinet temperature to ensure ice cream and frozen beverages are stored at optimal low temperature conditions with consistent taste. The built-in Energy Saving strategy intelligently optimizes compressor operation to reduce energy consumption and lower operating costs, enhancing market competitiveness.
The product features a compact 75×33×59mm design with panel snap-in installation, suitable for various small low-temperature refrigeration equipment modifications. The front panel meets IP65 protection rating, dust and water resistant, suitable for humid commercial environments. Equipped with multiple status LEDs (compressor, defrost, evaporator fan, energy saving, on/off), providing clear operation status at a glance for easy maintenance.
Supports multiple protective functions including door alarm (id), temperature alarms (AL/AH), probe faults (Pr1/Pr2), pressure switch alarm (iA), condenser overheat alarm (COH), and compressor shut down alarm (CSd), ensuring safe and stable equipment operation. Auto keyboard lock after 30 seconds of inactivity prevents misoperation, long press 1 second to unlock. Temperature unit can be switched between °C and °F via parameters. Ideal for ice cream display cabinets, convenience store freezers, supermarket frozen/refrigerated cabinets, and food service equipment.
