| timer bar 1–24 | Timer | Dark segments = chosen interval. |
| Uo | Ignition failure | Check the gas valve is open / gas supply. |

Les pièges de ce modèle
- Holding 난방 (not tapping) switches room vs water mode — a tap just turns heating off.
- In room mode the reading depends on where the controller hangs; drafts or sun make it wrong (manual note).
- Settings blink for 10 s before they save.
- Remembers its settings after a power cut.
- No 물보충 lamp: low water shows as error E1. 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.
Un code erreur s'affiche ?
Codes show on the LCD. Uo = no ignition (open gas valve); E1 = no water (check water cut, then A/S); E3 = overheating (open the floor manifold valves); E6 = gas leak; others call 1588-7339.
