4.2. Wiring
Warning: All wiring should be performed by a qualified electrician in accordance with local electrical codes and regulations. Ensure the power supply is disconnected before commencing any wiring work.
- Identify the power input terminals (typically marked L and N for Live and Neutral, or + and - for DC).
- Connect the temperature sensor to the designated sensor input terminals. Observe polarity if applicable.
- Connect the load (e.g., compressor, heater) to the relay output terminals. Ensure the load's power requirements do not exceed the controller's relay specifications.
- Verify all connections are secure and correct before applying power.
4.3. Initial Power-On
Once wiring is complete and verified, apply power to the controller. The display should illuminate, showing the current temperature or an initial setup screen. Refer to the operating instructions for initial parameter configuration.
5. Operating Instructions
5.1. Display Overview
The main display shows the current measured temperature. Various indicator lights provide status information:
- Temperature Value: Large red digits indicate the current temperature.
- °C / °F Indicator: Shows the unit of temperature measurement.
- Compressor/Heating Indicator: A light (often a snowflake or flame icon) indicates when the cooling or heating relay is active.
- Defrost Indicator: A light (often a fan or water droplet icon) indicates when the defrost cycle is active.
- Alarm Indicator: A light (often a bell or exclamation mark) indicates an alarm condition.
5.2. Basic Operation
- Power On/Off: Typically, the device powers on automatically when connected to a power source. Some models may have a dedicated power button or a combination of buttons to turn on/off.
- Viewing Setpoint: Press the SET button once to view the current temperature setpoint.
- Adjusting Setpoint:
- Press the SET button for approximately 3 seconds until the setpoint value flashes.
- Use the Up (▲) and Down (▼) arrow buttons to adjust the desired temperature.
- Press SET again to confirm and save the new setpoint, or wait a few seconds for it to save automatically.
- Accessing Parameters Menu: Press and hold the SET button and the Down (▼) button simultaneously for several seconds to enter the parameter configuration menu. Refer to the detailed parameter list for specific settings.

6.2. Inspection
Periodically inspect the wiring connections for any signs of loosening, corrosion, or damage. Ensure the temperature sensor is securely in place and free from obstructions. Check for any unusual noises or smells coming from the unit, which could indicate a problem.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank | No power supply; incorrect wiring; internal fault. | Check power connections and supply. Verify wiring. If problem persists, contact support. |
| Temperature reading is inaccurate | Sensor fault; sensor not properly installed; incorrect calibration. | Check sensor connection and placement. Replace sensor if damaged. Check calibration parameters. |
| Controller not activating load (e.g., compressor) | Setpoint not met; relay fault; load wiring issue; parameter settings. | Verify setpoint and differential. Check load wiring. Review operating parameters (e.g., defrost cycles, delays). |
| Error code displayed (e.g., "E1", "P1") | Specific sensor or system fault. | Consult the full product manual for specific error code definitions and solutions. |
