Digital Temperature Controller -40°C to 110°C with LCD Display and Micro Thermostat Functionality

[Simple to Use]: Temperature range: -40°C to 110°C. Easy to set and adjust with HD LCD display and four buttons. Relay-type temperature controller—requires separate power supply for the connected load. [High Current 30A Relay]: Rated for 220V AC, 30A. Suitable for high-power equipment such as refrigerators, brooders, incubators, fermenters, and greenhouses. Connect power supply and heating/cooling devices, place the sensor, and set desired temperature for reliable operation. [Heating/Cooling Function]: Heating Mode (H): Relay activates when measured temperature is less than or equal to (set temperature − hysteresis); deactivates when measured temperature reaches set temperature. Cooling Mode (C): Relay activates when measured temperature is greater than or equal to (set temperature + hysteresis); deactivates when measured temperature falls to set temperature. [Delay Start & Temperature Correction]: Delay Start (OPH): After completing a heating or cooling cycle, the system waits for the configured delay time before initiating the next cycle. Temperature Correction (OFE): Adjustable from -10.0°C to +10.0°C to compensate for sensor drift. Actual temperature = measured temperature + correction value. [High-Temperature Alarm]: Triggers audible and visual alarm and cuts relay output when temperature reaches the preset alarm threshold. Press any button to silence the alarm. Usage Steps: 1. Connect sensor to controller. 2. Power the controller. 3. Set start temperature, stop temperature, and temperature correction. 4. Disconnect power. 5. Connect load to relay output terminals (if required). 6. Reconnect power to controller. 7. Test and operate. Color: As shown Material: Plastic Package Contents: As listed
