Keywords: digital temperature controller, ECS-974T thermostat, defrost fan controller, Smart Life wifi temperature controller, refrigerator thermostat

Digital refrigeration temperature controller with compressor, defrost and fan outputs, a -50°C to 99°C measuring and controlling range and Smart Life WiFi remote monitoring.

Key Features

1.  Refrigeration, Defrost and Fan Outputs: Compressor output for refrigeration, defrost output for automatic or manual defrost, and fan output for air circulation — flexible configuration for various temperature control needs.

2.  Wide Temperature Measurement Range: Stable and accurate control across a wide temperature range (see "Technical Specifications" below for the exact figures).

3.  Bright LED Display: Displays real-time current temperature and setpoint values; clear and visible readings even in low-light conditions.

4.  Safety and Protection Functions: Compressor delay protection to prolong compressor life; over-temperature alarms to prevent system damage.

5.  Easy Programming and Operation: Simple button interface for quick setup and adjustments; supports manual calibration for precise system tuning.

6.  Wi-Fi Remote Control: 2.4G Wi-Fi connection for remote check and control via the Smart Life app.

7.  Copy Card Support: Parameters can be uploaded to / downloaded from a copy card for quick batch setting.
