¿Cómo…?
Calentar la habitación a una temperatura
- 1Touch 난방/온수 until 실내 shows.
- 2Touch + / − to 22 (range 10–40°C, default 25).
- 3Stop touching; after a few seconds it shows the current room temperature and fires (연소) if the room is colder.
Modo suelo (ondol)
- 1Touch 난방/온수 until 바닥 shows.
- 2Touch + / − to 60 (range 46–80°C, default 55).
- 3Setting exactly 45 switches to 보온 (keep-warm) mode: 30 min on, 3 h off, repeating.
Salir unos días
- 1Pick 바닥 or 실내 with 난방/온수 and set the temperature (e.g. 바닥 50).
- 2Touch 외출/타이머 so 바닥 (or 실내) and 외출 show together.
- 3Touch + / − to the pause in hours (e.g. 4; range 1–24).
- 4Stop touching; it blinks 4 s and is set. It now heats 20 min every 4 h.
Programar
- 1Same as Away: choose 바닥 or 실내 and a temperature, touch 외출/타이머, set hours with + / −.
- 2Example from the manual: 바닥 65°C + 6 h = runs 20 min at 65°C every 6 h.
- 3Timer does not work in 온수전용 mode.
Solo agua caliente (verano)
- 1Touch 온수전용. 온수 shows; heating is off.
- 2The boiler fires only when a hot tap is open.
Ajustar el agua caliente
- 1Touch 온수전용.
- 2Touch + / − (steps of 5 or 10°C; range 45–80°C, default 70). This is the boiler's internal water temperature, not the tap temperature — 50–55 is usually enough.
- 3Touch 난방/온수 to go back to heating; heating uses the same hot-water setting.
Apagar
- 1Touch 전원.

Trampas de este modelo
- Floor 45°C is a special keep-warm mode (30 min on / 3 h off), not just 'low'.
- After a few seconds the display stops showing your setting and shows the current temperature — that is normal.
- Remembers settings after a power cut.
- Keep the boiler plugged in during winter; its freeze protection needs power.
- This boiler normally refills itself. If 'd1' blinks with 연소, check for a building water cut. 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.
¿Sale un código de error?
Codes show on the display with the 연소 lamp blinking. From the manual: E1 = gas leak (unplug, ventilate, call A/S); d1 = water supply cut — check, then A/S; P6 = water refill needed; P4 = leak, check then A/S.
