Max.number of collectors:2
Main Functions: Timing heating Temperature difference control 2*ΔT Collector emergency shutdown Collector cooling function Collector low temperature protection Collector frost protection Tank re-cooling function Maximum temperature of tank ( 2*storage tanks) Maximum turnoff temperature (for solid fuel boiler return heating heat transferring between tanks) Minimum turnon temperature (for solid fuel boiler return heating heating transferring between tanks) Anti-Legionella function Temperature controlled hot water circulation pump RPM speed controlling (1*semiconductor) Thermal energy measuring Priority logic of multiple-tanks(2*storage tanks) High temperature by-pass function(Collector cooling down) Manual Control( for 5 outputs:R1...R4H1) Password setting Recovery to factory setting Holiday fucntion Manual Heating Temperature query function Memory Protection Screen protection Trouble shooting Trouble protection Trouble checking TECHNICAL DATA Dmension: 191mm x140mm x40mm Power supply:200V-240V AC or 100V-130V AC50-60Hz. . Power consumption: < 3W Accuracy of temperature measuring: ± 2oC Range of collector temperature measuring: -10oC ~200oC Range of tank temperature measuring: 0oC ~110oC Suitable power of pump: 5 pumps possible to be connected power of each pump < 200W . Inputs: 6 sensors 2pcs*Pt1000 sensor (≤500oC) for collector (silicon cable≤280oC) 4pcs*NTC10K B3950 sensor (≤ 135oC) for tank (PVC cable ≤105oC) Outputs:5 relays for circulation pumps or 3-way electromagnetic valve Ambient temperature:-10oC ~ 50oC. Water proof grade: IP40. Working Principle:
This type use all-glasses evacuated tubes as the solar collector for absorbing sun energy and transferring it into heat energy. As the different densities of hot water and cold water, the hot water flows automatically upwards while the cold water flows down. The water flowing cycle is created in the tube. And the water in the storage tank is heated from this natural circulation. The hot water pressure of this non-pressure system is from the gravity, so it should be installed on the roof or at least 3-4 meters higher than hot water tap. Or you can install a booster pump to get stronger outlet hot water.
Optional Accessories:
1. Booster Pump (adding the hot water out pressure) 2.Temperature Monitor(showing hot water temperature inside the main tank) 3. Electrical Heater (as back-up for cloudy or rainy day)
