An older Kiturami (HOMSYS) wall controller: one round button cycles Room / Timer / Away, side buttons set the temperature, season and timer.

9Power · 전원jeonwonTurns the controller and boiler on/off. Also resets the boiler after an error (3 tries in a row, then wait 5 min).
어떤 설정이 좋나요?
Winter: 실내 mode, wanted temp 21–22°C, season 겨울 (80°C water). Spring/autumn: 초겨울 or 봄. Out for the day: 외출. Avoid 예약 unless you set sensible numbers (about 20–30 min on / 1–2 h off).
어떻게 하나요?
켜기
1Press 전원 (big round button, bottom right).
2The screen lights up and shows the last mode used.
실내 온도 맞추기
1Press 실내·예약·외출 until the top-left of the screen says 실내.
2Press ▲ or ▼ until the right number (희망온도) shows 22.
3Press 계절선택 until the bottom of the screen says 겨울 (Dec–Feb) or 초겨울 (Nov, March).
4Wait. The 운전 light is on while the room is colder than 22°C and goes off when it reaches it.
며칠 집 비울 때
1Press 실내·예약·외출 until the screen says 외출.
2Leave the power ON — the boiler needs power and gas to protect the pipes.
3In a deep freeze (below about −10°C outside) use 실내 at 10–15°C instead, as the manual advises.
예약 설정
1Press 실내·예약·외출 until the screen says 예약.
2Press 예약설정. One number flashes — set it with ▲/▼.
3Press 예약설정 again. The other number flashes — set it with ▲/▼.
4Left number = 예약가동 = minutes the boiler RUNS. Right number = 예약정지 = hours it RESTS.
5Example from the manual: 20 min on, 2 h off, repeating. A good winter start is 20–30 min on / 1–2 h off.
6Stop touching it for a few seconds and it saves.
온수만 (여름)
1This model has no 'hot water only' button.
2In summer press 실내·예약·외출 until it says 외출: heating stays off unless pipes risk freezing, and taps still give hot water.
3Optional: press 계절선택 until it says 여름 (lowest radiator water temp, 45°C).
끄기
1Press 전원. Screen goes dark.
2In winter, use 외출 instead of switching off so the pipes cannot freeze.
화면 글자는 무슨 뜻인가요?

이 모델에서 자주 헷갈리는 점
A wanted temp of 30°C (as in one photo) means the boiler basically never stops — big gas bill. 21–23°C is plenty.
Timer trap (photo 49): 예약 showing 60분 예약가동 / 22시간 예약정지 means the boiler runs 60 minutes and then rests 22 HOURS. The room will be cold almost all day. Lower the 정지 number to 1–2 hours or switch back to 실내.
계절선택 (season) only changes how hot the radiator water is. Setting 여름 does not turn the heating off — use 외출 for that.
목욕 switches back to the previous mode after 2 h 30 min by itself.
The one round mode button cycles 실내 → 예약 → 외출. If you overshoot, keep pressing — it loops.
에러가 떠요
Errors flash on the screen as 'Er' plus a number, and the screen may also show 'A/S 문의는 1588-9000'. From the CTR-5700PLUS manual: Er 01 = burner did not light, Er 03 = flame went out (check the gas valve is open), Er 95 = low water (refill/pressure), Er 96 = overheat, Er 97 = gas leak detected (open windows, do not use switches, call). Press 전원 (power) off/on to restart — it only allows 3 restarts in a row, then wait 5 minutes. If it comes back, call 1588-9000.
