• Duplicated trouble : Option trouble with slight or heavy trouble
- 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 sanitary water heating can be impossible in emergency operation mode.
When sanitary water is not warming up while emergency operation, please check if sanitary
water sensor and related wiring are all Ok.
• Emergency operation is not automatically restarted after main electricity
power is reset.
- In normal condition, the product 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 product.

been running.
