- The temperature probe must be securely connected to ensure accurate readings and safe operation.
- Avoid installing the device in areas with high humidity or extreme temperatures outside its operating range.
3. Product Features Overview
The GUETNEU XS-036-WK-1 offers several features designed for efficient and reliable temperature control:

- LED Display: Provides clear, real-time temperature readings.
- Three Modes: Easily switch between Heating, Cooling, and Countdown modes.
- PA66 Material: Constructed from premium PA66 for insulation, heat resistance, and chemical resistance.
- 94V-0 Flame Retardant: Enhances safety by preventing fire spread.
- High Precision Temperature: Ensures accurate temperature monitoring and control.
4. Installation and Wiring
Proper installation is crucial for the safe and effective operation of the temperature controller. This device is designed for DIN rail mounting.
4.1. DIN Rail Mounting
The controller features a sliding rail clip for easy installation onto a standard DIN rail. Ensure the rail is securely mounted before attaching the device.
4.2. Connecting the Temperature Probe
The temperature probe connects to the dedicated port on the side of the controller. Ensure a firm and secure connection.

The probe cable length is approximately 6.56 feet (2 meters), allowing for flexible placement to monitor the desired temperature accurately.
4.3. Electrical Wiring
Connect the input terminals (N and L) at the top of the device to your 110/220V AC power supply. Connect the output terminals (N and L) at the bottom to the load (e.g., heating element, cooling fan). Always ensure proper polarity (Neutral to N, Line to L).

5. Operating Instructions
The controller features an LED display and three buttons: On/Off, SET, +, and - for configuration.
5.1. Setting Temperature Parameters
Press the "SET" button to enter the setting sequence. Use the "+" and "-" buttons to adjust the values. The sequence typically involves setting the Operating Temperature and Stop Temperature.

5.2. Heating Mode
In Heating Mode, the device activates when the operating temperature is below the set operating temperature and deactivates when it reaches the set stop temperature. This mode is suitable for applications requiring temperature increase.

5.3. Cooling Mode
In Cooling Mode, the device activates when the operating temperature is above the set operating temperature and deactivates when it drops to the set stop temperature. This mode is ideal for applications requiring temperature reduction.
5.4. Countdown Mode
Press the "SET" button to switch to the countdown timer function. Use the "+" and "-" buttons to adjust the timer from 1 minute to 24 hours. When the countdown begins, the blue light will illuminate, and the device will automatically power off the output terminal once the timer expires.
6. Temperature Calibration
After powering on, press and hold the "SET" button for more than 5 seconds to enter the temperature calibration function. You can adjust the temperature deviation by ±10°C to fine-tune accuracy. This feature ensures the product's temperature readings align with your specific requirements.
