Figure 4.1: Close-up view of the HJM LAGAN 500W control panel with digital display and control buttons.
The control panel typically includes a digital display, power button, temperature adjustment buttons (+/-), mode selection, and programming buttons. Refer to the display for current temperature, mode, and program status.
4.2 Basic Operation:
- Power On/Off: Press the power button (usually indicated by a ⏻ symbol) to turn the radiator on or off.
- Set Temperature: Use the '+' and '-' buttons to adjust the desired room temperature. The display will show the set temperature.
- Mode Selection: Press the mode button (often a 'M' or similar icon) to cycle through available modes such as Comfort, Economy, Anti-freeze, or Programmed mode.
4.3 Programming (24/7):
The radiator offers flexible programming options to suit your lifestyle and optimize energy consumption.
- Pre-installed Programs: The unit comes with 9 pre-installed automatic programs for quick setup. Consult the on-screen menu or specific programming section in the full manual for details on selecting and activating these.
- Customizable Programs: You can create up to 4 personalized daily and weekly programs. This typically involves setting desired temperatures for specific time slots throughout the day and week. Access the programming menu via the control panel and follow the on-screen prompts.
4.4 Special Functions:

If storing the radiator for an extended period, ensure it is clean, dry, and stored in a cool, dry place, protected from dust and direct sunlight.
6. Troubleshooting
If you encounter issues with your radiator, refer to the following common problems and solutions before contacting customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Radiator does not turn on. | No power supply. Power button not pressed. Keyboard lock activated. | Check if the power cord is securely plugged in and the outlet is functional. Check your circuit breaker. Press the power button. Deactivate the keyboard lock. |
| Radiator is on but not heating. | Temperature setting too low. Open window detected. In Anti-freeze mode. | Increase the set temperature above the current room temperature. Close any open windows or doors. The radiator will resume heating. Change the operating mode to Comfort or Programmed. |
| Radiator heats intermittently. | Normal operation (thermostat cycling). Programmed schedule. | This is normal as the radiator maintains the set temperature. It will cycle on and off. Check your programmed schedule to ensure it aligns with your desired heating times. |
| Unusual noises from the radiator. | Expansion/contraction of materials. Air in the system (unlikely for sealed fluid radiators). | Minor clicking or creaking sounds are normal as the metal heats and cools. If loud or persistent, contact customer support. |
| Display shows an error code. | Internal fault. | Note the error code and consult the full product manual or contact customer support. |
