it has perfect 14 Function system, to come true your water heater keep safety, energy-saving, and convenient First, power-on self-test To tell you the machine is belong to normal estate. Let you feel easement. Second, water level preset. According to your using requirement of hot water, setup water level in advance arbitrarily, keep sun energy and water energy reach the best matching. Third, watering with brainpower Heat up with solar energy from low water level, to insure the using range of water temperature keep above 45℃, up to fill water tank , watering with brainpower insure the need of hot water. Fourth, water level show Controller interface intuitionistic show the water level in water box, and setting is more convenient. Fifth, water temperature show Let you espial the water temperature exactly, Sixth, watering on time Easy to settle some problems in other regions, such as : can¡¯t support water a day, low hot pressure in day, difficult to watering,etc. and it will watering when the water pressure is high. Seventh, use low water pressure to watering During water process, if you meet low water pressure or shut-down, the controller will enter into low water pressure mode automatically. Eighth, watering automatically when the lack of water When the lack of water state appeared, the water will added to water level after 15 minutes automatically. Ninth, manual control Come true your especial need in especial conditions. Manual watering, manual calefaction, the design shows more human nature . Tenth, calefaction intellectualized When it can¡¯t get advance temperature it will use solar energy to heat. And startup electrical heat to supply energy to advanced temperature, Then it will stop automatically. It not only save your electric energy, but also ensure your hot water temperature. Eleventh, piping heat preservation It especially suitable for cold north region,it can startup tube electrical heat job, actualize tube heat preservation to insure the normal condition of system. let you s |
