	Working Liquid (Chilled Water) Temp	5 to 35 ℃
		0 to 35 ℃
	Freeze-Prevention Mode	This function operates the discharge pump in order to prevent drops in water temperature and freezing during winter months when the product is not otherwise operating. When enabled, the discharge pump will operate when the water temperature falls to 3 ℃ or below.
	Warm Up Mode	This function will automatically operate the discharge pump at times when the product is otherwise not operating when the ambient temperature is low, for example during winter months, in order to prevent the water temperature from dropping too much and in order to help maintain the set water temperature. When this mode is enabled, the water temperature can be set within the temperature range of 10 to 35 ℃ as desired.
	Low Noise Mode	This function will limit the upper speed of the fan, thus reducing the fan ventilation noise. ※4

	Liquid (Chilled Water) Temp Upper/Lower Limit Warning Option	The method of abnormal liquid (chilled water) temperature detection can be selected. Can enable or disable the alarm and standby sequence for relative value and absolute value alarms. ※ Regarding the standby sequence, the alarm will be output after startup until the liquid temperature has initially reached a normal value and then later goes outside the normal range.
	Liquid (Chilled Water) Temp Upper/Lower Limit Warning / Absolute Value Upper Limit	The warning will occur if the liquid temperature goes above the set temperature (2 to 40 ℃) regardless of the actual set water temperature. Will be enabled when the absolute values for "Liquid (Chilled Water) Temp Upper/Lower Limit Warning" have been selected.
