Digital Temperature Controller -40°C to 110°C, LCD Display, Waterproof Sensor

[Simple to Use]: The temperature range for this temperature controller is -40°C to 110°C. Easy to set and adjust, with HD LCD display and 4 buttons. It is a relay-type temperature controller; an external power supply is required for the load. [High Current 30A Relay]: Rated for 220V AC, 30A. Suitable for high-power equipment such as refrigerators, brooders, incubators, fermenters, and greenhouses. Connect the power supply and heating/cooling device, place the sensor, and set the desired temperature — it will operate reliably. [Heating/Cooling Function]: Heating Mode ('H'): When the measured temperature is less than or equal to the set temperature minus hysteresis, the relay activates to power the heating device. When the measured temperature reaches or exceeds the set temperature, the relay deactivates and the heating device stops. Cooling Mode ('C') operates on the same principle in reverse. [Delay Start & Temperature Correction Function]: Delay Start ('OPH'): After completing a heating or cooling cycle, the system begins a timer 'T'. Once 'T' equals or exceeds the OPH value, the next heating or cooling cycle may begin. Temperature Correction ('OFE', range: -10.0°C to +10.0°C): Compensates for long-term measurement drift. Actual temperature = measured temperature + correction value. [High Temperature Alarm Function]: If the actual temperature reaches or exceeds the alarm threshold, the system activates audible and visual alarms and cuts power via the relay. Press any button to silence the alarm and reset the indicator. Usage Steps: 1. Connect the sensor to the controller. 2. Connect power supply to the controller. 3. Set start temperature, stop temperature, and temperature correction. 4. Disconnect power supply. 5. Connect the load (heating/cooling device) to the relay output terminals, ensuring proper power supply connection. 6. Reconnect power supply to the controller. 7. Test and begin operation.
