Emergency operation
• Definition of terms
- Trouble : a problem which can stop system operation, and can be resumed temporally under limited operation
without certificated professional's assist.
- Error : problem which can stop system operation, and can be resumed ONLY after certificated professional's
check.
- Emergency mode : temporary heating operation while system met trouble.
• Objective of introducing 'trouble'
- Not like airconditioning unit, Air-to-Water heat pump is generally operating in whole winter season without any
system stopping.
- If system found some problem, which is not critical to system operating for yielding heating energy, the system
can temporarily continue in emergency mode operation with end user's decision.
• Classified trouble
- Trouble is classified two levels according to the seriousness of the problem : Slight Trouble and heavy trouble
- Slight trouble : Sensor trouble.
- Heavy trouble : Compressor cycle trouble.
- Option trouble : a problem is found for option operation such as water tank heating. In this trouble, the trou-
bled option is assumed as if it is not installed at the system.
• When the AWHP has any trouble,
(1) If there is not a function to judge possibility of operation : Once an error occurs mainly in outdoor unit, AWHP
stops. On the other hand, Remocon allows the product to activate On/ Off operation.(On : emergency opera-
tion)
- Slight / Heavy trouble : Heating Operable only
- Critical trouble : Full stop

ble, pop-up phrase is guided separately on display.
