XY-DT01 Digital Temperature Controller -40°C To 110°C LCD Display Thermostat

[Simple to Use]: Temperature range: -40°C to 110°C. Easy to set and adjust with HD LCD display and 4 buttons. Relay-type temperature controller; external power supply required for the load. [High Current 30A Relay]: Rated capacity: 220V AC, 30A. Suitable for high-power devices such as refrigerators, brooders, incubators, fermenters, and greenhouses. Connect power supply and heating/cooling equipment, place the sensor probe, and set desired temperature — ready to operate. [Heating/Cooling Function]: Heating Mode ('H'): Relay activates when measured temperature is less than or equal to (set temperature – hysteresis), turning on heating equipment; relay deactivates when measured temperature reaches set temperature, stopping heating. Cooling Mode ('C') operates on the same principle. [Delay Start & Temperature Correction]: Delay Start ('OPH'): After completing a heating or cooling cycle, the system begins timing; once the delay period elapses, the next cycle starts automatically. Temperature Correction ('OFE'): Adjustable from -10.0°C to +10.0°C to compensate for long-term measurement drift. Actual temperature = measured temperature + correction value. [High-Temperature Alarm]: When actual temperature reaches alarm threshold, audible and visual alarm activates and relay disconnects. Press any button to silence alarm. Usage Steps: 1. Connect sensor to controller. 2. Connect power supply to controller. 3. Set start temperature, stop temperature, and temperature correction. 4. Disconnect power supply. 5. If required, connect load and power supply to relay output terminals. 6. Reconnect power supply to controller. 7. Test and begin operation.
