If option trouble is occurred with slight (or heavy) trouble at the same time, the system puts higher priority to
slight (or heavy) trouble and operates as if slight (or heavy) trouble is occurred.
Therefore, sometimes DHW heating can be impossible in emergency operation mode. When DHW is not warm-
ing up while emergency operation, please check whether the DHW sensor and related wiring are connected well
or not.
• Emergency operation is not automatically restarted after main electricity power is reset.
In normal condition, the unit operating information is restored and automatically restarted after main electricity
power is reset.
But in emergency operation, automatic re-start is prohibited to protect the unit.
Therefore, user must restart the unit after power reset when emergency operation has been running.
