1-1-1 Major Part Characteristics
Part Name FEED valve / NOS valve (for safety cutoff)
Use Source water entry and safety cutoff function
Operation
principles
Opens and closes the flow path when full water signals from the low water level/full
water level sensor and overflow sensor are detected to stop entry of source water
in two ways.
Part Name Low water level / Medium water level / Full water level sensor (capacitance sensor)
Use Water level detection in the room-temperature water tank
Operation
principles
Detects the room-temperature water tank level in three stages and adjusts room-
temperature water operation through the FEED valve.
Part Name Overflow sensor (capacitance sensor)
Use Water level detection in the room-temperature water tank
