[Input and Output]
1.Input Signal
1) Temperature Probe storage tank top T1
2) Temperature Probe collector T2
3) Temperature Probe storage tank below T3
2.Output Control
1) Electric Heating
2) Circulation 1
3) Circulation 2[Main Function]
1.Time Display: the clock time is displayed in 24hours system.
2.Temperature Indication: display temperature of the solar heat collector and the water tank.
3.Circulation Pump 1 (temperature difference circulation).
3.1 When 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 if stared to exchange heat. The set temperature of start of the circulation pump: 2-20¡æ (default is 10¡æ).
3.2 When 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: 0-15¡æ (default is 5¡æ)
4.Circulation Pump 2 (timing circulation)
4.1 Working Principle: the working principle of the timing circulation 2: to work from 19: 00-22:00(working course: the circulation pump works in the circulation of running for 1 minute and stopping for 3 minutes).
5.The working Principle of Timing Heating: when the set time is up and the temperature of the top of the water tank (T1) is 6¡æ lower than the set temperature of water , the electric heating is started while the temperature of the water tank is up to the set temperature of water or the set time is up, the electric heating is stopped.
6.Anti-Freezing Protection: when the temperature of the water tank is lower than 10¡æ, the electric heating is Started forcibly while when it is higher than 15¡æ, the electric heating is stopped.carton
