The term "thermostat", which is widely used in this chapter, is a kind of 3rd party accessory. LG Electronics does not supply thermostat and it should be supplied 3rd party manufacturers. Room thermostat can be used for easy and convenience control. To utilize thermostat more efficient- ly and correctly, this chapter presents information about using thermostat.

Using Thermostat Emergency Operation • Definition of terms - Trouble : a problem which can stop system operation, and can be resumed temporally under limit- ed operation without certificated professional's assist. - Error : problem which can stop system operation, and can be resumed ONLY after certificated professional's check.
Page 29
Using Thermostat • 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.
