켜기
- 1Press 전원 (top right). The 실온 or 온돌 lamp lights.
- 2Turn the 난방 dial into the 저–고 arc.
A simple Rinnai panel with one big heating dial (저 low to 고 high), a 실온/온돌 mode button, a 예약 timer button and a hot-water button that steps 저/중/고.

실온 mode, dial set so the screen reads 22°C; 온수 on 중. Leaving for a day or more in winter: dial to 외출, not 꺼짐 or 전원 off.
| 실온 램프 | Room lamp | Room-air mode is active; the dial target is an air temperature (5–40°C). |
|---|---|---|
| 온돌 램프 | Floor lamp | Floor-water mode is active; the target is the water temperature (40–85°C). In 온돌 mode the set value only shows while heating is on. |
| 예약 램프 | Timer lamp | The repeat timer is running. |
| 30 / 1h / 2h / 3h / 4h | Timer interval | Shown on the screen when you press 예약: the gap between 20-minute heating bursts. |
| 불꽃 + 빨간 점 | Flame + red dot | Burner is firing. |
| 온수 저/중/고 램프 | Hot water level | Steady = hot water on at that level. Blinking = hot tap is open and the boiler is heating water. |
| 깜박이는 숫자 (11, 14, 16…) | Blinking number | Error code — see error help. |
If the boiler stops and a number blinks on the screen, read the number. 11 = no ignition: check the gas valve on the pipe is open (handle parallel to the pipe), then switch heating off and on. 14 = overheat cut-out: wait up to 30 min, then switch on again. 16 = water overheating: open at least one floor-zone valve on the manifold and bleed air. Anything repeating: call Rinnai A/S 1544-3651. 35 = room sensor fault: switch to 온돌 mode and call A/S.
