Rinnai RICH-02CR in English
The living-room master of an older Rinnai multi-room system: it controls every room's floor valve AND the Rinnai gas boiler (hot water, heating-water temperature) with a big dial.
We could not find this exact model's manual, so these steps come from its closest sibling. If your panel behaves differently, send us a photo.

How do I…?
Heat the room to a set temperature

- 2Turn the dial until 설정 reads 22.
- 3Press the centre 설정 button to confirm.
Leave for a few days

- 2Press 외출 again when you are back.
Run on a timer
- 1Hold 기능선택 for 3 seconds (예약).
- 2Turn the dial to set hours.
- 3Press 설정. Heating stays off for that time and then starts (unverified on this exact model).
Hot water only (summer)
- 1Press 전체난방 to switch room heating off.
- 2Make sure 온수 shows on the screen; if not, press 온수. Hot water keeps working with heating off.
Change the hot-water temperature
- 1Press 기능선택 repeatedly until hot-water temperature (온수 온도) flashes.
- 2Turn the dial to set it (about 45°C is comfortable and safe).
- 3Press 설정 to confirm.
Turn it off
- 1Press 전체난방 to turn all rooms off, or 난방 for just the selected room.
What do the words on the screen mean?
| 현재 / 설정 | Current / Set | Room temperature now / target. |
|---|---|---|
| 온수 | Hot water | Boiler hot water enabled. |
| 거실, 방1-방5 | Living room, rooms 1-5 | Zones; a mark beside one means that room's valve is open and it is heating. |
| 오전/오후 | AM/PM | Clock. |
What trips people up on this model?
- This panel controls the boiler too: turning 온수 off means no hot shower even though the boiler is fine.
- Settings apply to the room highlighted by 방선택. Check the room before turning the dial.
- RICH-02 is discontinued (replaced by RICH-04 / RICH-W). Repairs usually mean replacing the whole set.
