What trips people up on this model?
- In the photo 선택 sits on the left (온수전용) — that means NO heating. Slide it right in winter.
- No room-temperature mode; the dial sets boiler-water temperature.
- No timer on this panel.
- 급속 burns a lot of gas — use only briefly.
- If the 물보충 (water refill) light or code comes on, the boiler is low on heating water and will stop to protect itself. Do not open panels or valves. Message your landlord / building manager first, then call the A/S number. A light that keeps coming back usually means a leak.
- Lotte left the boiler business in 2020; spare parts are now scarce and the printed number may not reach Lotte service. Ask your landlord first — repairs often mean a boiler replacement.
