If the Newlec NLSH050 is on but not producing heat, possible issues could include:

1. Comfort Off Period – The heater may be in a scheduled ‘Comfort Off’ period, during which it does not deliver heat.
2. Incorrect Settings – The programmable timer may be set to a mode like ‘Out All Day,’ preventing heat output.
3. Open Window Detection – If the heater detects an open window, it may reduce or stop heating to save energy.
4. Energy Storage Issue – The heater may not have stored enough energy due to incorrect charging or insufficient power supply.
5. Advance Mode – If the Advance button has been pressed, it may override the heating schedule.
6. Display Sleep Mode – The display may appear inactive, but pressing a button will reactivate it to check settings.

Checking the timer settings, ensuring no open windows are detected, and verifying energy storage levels can help resolve the issue.
