Temp Contr STC-9200 Double 220V

Description

The STC-9200 Digital Temperature Controller is an advanced, commercial-grade microcomputer thermostat specifically designed to manage complex refrigeration setups. Operating on a standard 220V AC current, this high-precision controller features three output relays, allowing it to simultaneously regulate your compressor (cooling), an automated defrost system, and an evaporator fan.Equipped with a dual-sensor array (two independent NTC waterproof thermistor probes), the STC-9200 monitors both the ambient storage space and the evaporator coil temperature. This intelligent design allows the controller to trigger defrost cycles based on actual frost conditions rather than a rigid timer, optimizing energy efficiency and preventing unnecessary heating of your cooling chamber.Technical Specifications & FeaturesPower Supply: 220VAC $pm$10%, 50/60HzTemperature Measuring & Control Range: $-50^circtext{C}$ to $50^circtext{C}$Dual Sensor System: Includes 2 NTC Sensor Probes (Room temperature probe + Defrost/evaporator coil probe).Triple Output Relay Capacity:Refrigeration/Compressor Relay: 8A / 220VACDefrost Relay: 8A / 220VACEvaporator Fan Relay: 8A / 220VACIntelligent Fan Management: Programmable fan modes (continuous, cycle-delayed, or tied to the compressor state) to maximize air distribution and humidity control.Safety Protocols: Built-in buzzer alarm and visual display flashing for over-temperature limits or sensor faults.Compatible Appliances & SystemsBecause of its unique ability to control the evaporator fan independently from the compressor, the STC-9200 is the industry-standard retrofit choice for air-cooled and ventilated sub-zero refrigeration equipment:Walk-In Cold Rooms & Blast Freezers: Perfectly manages commercial walk-in chillers, meat lockers, and low-temperature storage facilities requiring forced-air circulation.Air-Cooled Display Cases: Ideal for supermarket open-front multi-deck displays, glass-door beverage coolers, and commercial ice cream islands.Commercial Kitchen Refrigeration: Directly compatible with restaurant reach-in line freezers, under-counter prep tables, and heavy-duty industrial ice machines.Cold Chain & Mobile Transport: Used to upgrade or repair localized mobile cooling units, marine refrigerators, and specialized cold storage shipping container boxes.Medical & Laboratory Cold Storage: Provides ultra-reliable temperature management for lab-grade specimen coolers or pharmacy vaccine freezers requiring active air circulation and dedicated alarm warnings.⚠️ Installation Safety Notice: Wiring this unit involves high-voltage 220V mains electricity. Ensure the power grid is entirely disconnected before installation. The two NTC thermistor sensor cables must be kept physically separate from the high-voltage load lines (compressor, heater, and fan power wires) to eliminate electromagnetic interference and prevent erratic display readings.
