Production details1.Good lookingIntroduceAPPLICATIONS CAPACITY Max.number of collectors:1 Max.number of storage tanks:1 Max.number of relays:4 Max.number of sensors:5 Max.number of application system:1 APPLICATIONS DESCRIPTION The solar circuit pump (R1) is switched on as soon as the switch-on temperature difference (ΔTon) between the collector array (T1) and the storage tank (T2) is reached. I f the temperature difference between the collector array (T1) and storage tank (T2) drops below the switch-off temperature difference (ΔToff), or the temperature of storage tank (T3) reaches the preset maximum storage temperature, then the solar circuit pump(R1)is switched off. Back-up heating by auxiliary boiler:Within the preset time section of back-up heating, if the temperature T3 is below the switch-on temperature, then the circulation pump(H1) of back-up heating is triggered, when T3 is heated to the switch-off temperature, circulation pump H1 of back-up heating is ceased.Main technical datas 1.Dmension: 120mm x120mm x23mm2.Installation: wall mounting,also suitable for mounting into patch panels3.Power supply:200V-240V AC or 100V-130V AC,50-60Hz. . 4.Power consumption: < 3W 5.Accuracy of temperature measuring: ± 2oC6.Range of collector temperature measuring: -10 ~200oC7.Range of tank temperature measuring: 0 ~110oC8.Suitable power of pump: 4 pumps possible to be connected, power of each pump < 200W . 9.Inputs: 5 sensors, 10.Pt1000 sensor (≤500oC) for collector (silicon cable≤280oC),11.NTC10K, B3950 sensor (≤ 135oC) for tank, (PVC cable ≤105oC), 12.Outputs:4 relays, for circulation pumps or 3-way electromagnetic valve 13,.Ambient temperature:-10oC ~ 50oC. 14.Water proof grade: IP40.Main functions details1.Timing heating2.Temperature difference control 1*ΔT3.Collector emergency shutdown4.Collector cooling function5.Collector low temperature protection6.Collector frost protection7.Tank re-cooling function8.Celsius and Fahrenheit temperature switch9.Maximum temperature of tank(max.number 1)10.Anti-Legionella function11.Temperature controlled hot water circulation pump12.RPM speed controlling(1*semiconductor)13.Thermal energy measuring14.Pump interval functions.15.High temperature by-pass function16.Manual Control( for 4 outputs:P1,P2,R1,H1)17.Password setting18.Recovery to factory setting19.Holiday fucntion20.Manual Heating21.Temperature query function22.Memory Protection23.Screen protection24.Trouble shooting25.Trouble protection26.Trouble checkingInstallation drawing
