STC-3028 220AC Digital Temperature Humidity Controller

Dual Temperature & Humidity Control: Integrated dual relay outputs allow simultaneous monitoring and automated regulation of both heating/cooling equipment and humidification/dehumidification systems.

220V AC Mains Operation: Powered directly by a standard 220V AC electrical line, eliminating the need for external power transformers or step-down converters.

Dual High-Brightness Digital Display: Crisp dual LED display provides real-time telemetry for ambient temperature and relative humidity (RH) side-by-side.

Integrated High-Precision Integrated Sensor: Includes a sensitive, integrated temperature and humidity combo sensor probe for reliable thermal and environmental sensing.

Comprehensive Protection Parameters: Configurable options for high/low alarm setpoints, relay delay protection, and independent sensor calibration for precise climate stability.

Housing Material: Flame-retardant ABS plastic panel-mount housing with side mounting clips and protective terminal covers.

Technical Specifications:

Input Voltage: 220V AC (-+ 10%), 50/60 Hz.

Temperature Range: -20°C – +80°C.

Humidity Range: 0% – 100% RH.

Relay Output Rating: 10A / 220VAC (per relay output).

Housing Color: Grey / Black Casing with Red/Blue LED Displays.

Usage Advice: Disconnect main 220V power before wiring phase, neutral, and load connections; ensure terminal screws are firmly tightened to prevent contact resistance.

Maintenance: Keep the integrated sensor housing free of heavy dust, moisture condensation, or oil residue to preserve measurement accuracy.

Essential All-in-One Climate Controller: Position as a complete climate automation module for egg incubators, green houses, mushroom cultivation, curing rooms, and reptile terrariums.

Highlight Combined Environmental Control: Emphasize how a single 220V unit simultaneously commands both temperature (heater/cooler) and humidity (humidifier/dehumidifier) without requiring dual devices.

Recommended Cross-Sell Add-ons: Pair with STC-3028 12V Digital Temperature Humidity Controller, STC-3028 24V Digital Temperature Humidity Controller, STC-3008 220AC Thermostat Dual Temperature Controller, and ESD antistatic mat 50x40CM PCB Welding Mat.
