Product characteristics·Electrical schematic diagram „ Product characteristics 1. Safe and reliable: Dry-heating prevention unit: under abnormal conditions, when the heating components of the water heater are at an overly high temperature, the hand-reset temperature controller will cut off the power supply automatically and stop heating. Low water pressure and low flow protection: in case of shutoff of water control valve or abrupt cutoff of water supply which results in the water flow lower than the minimum operating water flow, the water heater will stop working automatically. "Shockproof wall" patent design makes for safer use. 2. Advanced design, highly efficient and energy saving: A water switch is installed to realize electrification by water supply, electrical outage by cutting off water, heating while in use, high efficiency and energy saving. Small volume, light weight, easy selection of installation position, and easy fastening. Pollution-free, long service life, novel environmental-friendly green product. 3. Multipurpose: Enclosed structure, able to connect with several outlets. „ Electrical schematic diagram L: Live wire (brown/red/black) N: Zero line (blue) E: Ground electrode (yellowish green) MT: Hand-reset temperature controller EH: Heating pipe K1, K2 and K3: switches HL1, HL2 and HL3: Indicator lamps BT: Constant temperature controller Note: This is the line diagram of DSF65/80B (E) 1
