limited operation without certificated professional's assist.
- Error : problem which can stop system operation, and can be resumed ONLY after certificated
professional's check.

• Objective of introducing 'Trouble'
- Not like airconditioning product, Air-to-Water heat pump is generally operation 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

sensor problems. The outdoor unit is operating under emergency mode operation condition
which is configured by DIP switch No. 4 of the unit PCB.
- Heavy trouble : a problem is found inside the outdoor unit. As the outdoor unit has problem, the
emergency mode operation is performed by electric heater located in the unit.
- Option Trouble : a problem is found for option operation such as water tank heating. In this
trouble, the troubled option is assumed as if it is not installed at the system.
• When the AWHP has any trouble,

the product to activate On/ Off operation. (On : emergency operation)
- Slight / Heavy trouble : Heating Operable only
