Product features

1. Multiple patents have been obtained in solar water heater and electric water heater at home and abroad.

2. Complete defensive functions: bipolar control, electric leakage detection, water leakage detection and dry burning-resistant protection with its homologous codes.

3. Real time monitoring on the states of solar hot water with real time clock display, tank temperature display, heat collector temperature display and other executing states display.

4. Four time slots of startup and shutdown settings are permitted, and each time slot of temperature control can be set separately. Workday and weekend can be set separately as well.

5. Real time recording on electric heating time and monitoring electricity consumption.

6. The functions of anti-freezing protection of heat collector and water tank temperature automatic cycle. Anti-freezing protection temperature spots and cycle temperature difference parameters can be set. Heat collection recycle pump, AC/DC pump compatibility can be opened constrainedly through display board and APP.

7. All setup parameters are recorded when power off, and backup battery keeps clock on.

8. 220VAC/24VDC solar cell is used in controller, monitoring alternating current power supply, and it automatically transfers to direct current 5-24V power supply with the function of direct current low voltage protection.

9. Local operation display panel is connected with main control panel through RS485, and keeps completely synchronized monitoring with remote control terminal.

10. Remote control method could be realized by PC, IOS APP or Android APP, entering internet wit WIFI or 3G, transmitting control command and state parameters by P2P data between cloud servers and ZIGBEE gateway (with TCP/IP protocol). Data transmission is realized with radio frequency identification between ZIGBEE gateway and ZIBGEE module. ZIBGEE module is fixed on the port of main press board RS485. The same with local display panel, it is a slave of RS485, real time transmitting the running state of solar water heater on main control panel and remote APP parameter setting as well as control command.

11. This system adopts the communication modes such as RS458, ZIGBEE RF radio frequency identification, internet, WIFI, 3G. It installs ZIGBEE module (with RS483 port) on main control panel, connects ZIGBEE TCP/IP radio network gateway to home or office wireless router, and then system accesses to internet, so it can monitor solar water heater by wireless remote APP through PC, IPHONE/IPAD, ANDROID phone or pad, thus realizing the function of Internet of Things. One ZIGBEE gateway could make it convenient for main control panel networking with one or more ZIGBEE modules. Networking mode could adopt center radiation networking and relay networking. The networking distance is large and each networking module has independent IP address.  On APP, at most 8 networking main control panels could be displayed. APP can switch to another APP for monitoring. This combination is very suitable for the solar water heater in hotel or office.

12. Jumper selection: solar control, electric water heater control

13. This system is suitable for voltage saving type and separated type solar water heater and electric water heater control.
