As products are improving and in systematization from time to time, we apologize that the product you purchased may have something differences with drawings in this instructions. Main Technical Data 1.Outline Sizes of Display: 170mm×128mm×40mm.2.Power Consumption: < 5W.3.Accuracy of Temperature Measuring: ±2C.4.Range of Temperature Measuring: 0 - 99C.5.Controlled Power of Circulation Pump: < 600W.6.Power of Electric Heating: ≤2000W. Input and Output 1.Input Signal1) Temperature Probe storage tank top T12)Temperature Probe collector T23) Temperatur Probe storage tank below T32.Output Control1)Electric Heating2)Circulation 13)Circulation 2 Main Functions 1. Time Display: the clock time is displayed in 24hour system.2.Temperature Indication: display temperatures of the solar heat collector and the water tank.3.Circulation Pump 1 (temperature difference circulation)3.1When the temperature of the heat collecting pipe (T2) is larger than the set temperature of the bottom of the water tank (T3), the circulation pump is started to exchange heat. The set temperature of start of the circulation pump: 2- 20C (default is 10C).3.2When the temperature of the heat collecting pipe (T2) is larger than the set temperature of the bottom of the water tank (T3), the circulation pump is stopped. The set temperature of stop of the circulation pump: 0-15C (default is 5 ). Protection Function 1. Anti-Freezing Protection: when the temperature of the water tank is lower than 10C, the electric heating is started forcibly while when it is higher than 15C, the electric heating is stopped.
