Temp Contr STC-9100 Double 220V

Description

The STC-9100 Digital Temperature Controller is an intelligent, high-precision dual-sensor thermostat designed explicitly for sub-zero cooling and refrigeration systems. Operating on a standard 220V AC current, this commercial-grade controller manages both active refrigeration (cooling) and automated defrosting cycles with absolute precision.Equipped with a bright, dual-color LED digital display and two independent NTC temperature thermistor probes, it continuously monitors both the ambient storage space and the evaporator coil temperatures. This allows the system to trigger smart, time-and-temperature-controlled defrosting patterns, preventing frost buildup, optimizing energy consumption, and protecting valuable inventory.Technical Specifications & FeaturesPower Supply: 220VAC $pm$10%, 50/60HzTemperature Measuring Range: $-50^circtext{C}$ to $50^circtext{C}$Dual Sensor Array: Includes 2 NTC Sensor Probes (one for room temperature, one for defrost control).Output Relay Capacity: * Refrigeration/Compressor Relay: 8A / 220VACDefrost Relay: 8A / 220VACExternal Alarm Relay: 8A / 220VACSafety & Warnings: Features multi-mode alarm outputs via buzzer or display flashing to warn users of sensor failures or extreme temperature overshoots.Compatible Appliances & SystemsThe STC-9100 is a universal retrofit controller engineered to replace or upgrade factory thermostats across a wide variety of commercial and industrial refrigeration equipment, including:Commercial Cold Storage Walk-ins: Ideal for walk-in coolers, medium-to-low temperature chillers, and localized cold room facilities.Commercial Display Freezers: Frequently used in supermarket open-air display cases, glass-door beverage coolers, and commercial ice cream freezers.Kitchen Refrigeration Equipment: Directly compatible with commercial reach-in line coolers, under-counter restaurant refrigerators, and prep tables.Seafood & Meat Storage: Controls specialized meat locker storage environments and seafood holding tanks requiring tight, reliable temperature boundaries.Medical & Lab Refrigeration: Provides reliable backup or primary temperature regulation for lab-grade specimen refrigerators or vaccine storage coolers requiring dedicated over-temperature alarm relays.⚠️ Installation Safety Notice: Wiring this unit requires working directly with high-voltage 220V mains electricity. Ensure the power source is entirely disconnected before installation. The two NTC thermistor sensor cables must be kept strictly separate from the high-voltage load lines (compressor and defrost power wires) to avoid electrical noise interference and erratic readings.
