The controller is suitable for closed loop, pressurized, split type solar hot water heater systems. It is capable of
controlling the operation of 6 different system configurations:
- Standard split pressurized solar water heating system with 1 collector array and 1 storage tank with single heat exchanger;
- Standard split pressurized solar water heating system with 1 collector array and 1 storage tank with double heat exchanger, with using gas boiler as auxiliary heating device;
- Standard split pressurized solar water heating system with 1 collector array and 1 storage tank with single heat exchanger, with electric heater as auxiliary heating device;
- Standard split pressurized solar water heating system with 1 collector array and 1 storage tank with single heat exchanger, with gas boiler as auxiliary heating device to realize heat collecting function;
- Standard split pressurized solar water heating system with 1 collector array to directly heat swimming pool;
- Standard split pressurized solar water heating system with 1 collector array to heat swimming pool using heat exchanger;
Buyer requirements
- have given more than 3 negative or netural feedbacks during past 60days.
- have received 3 or more negativeor netural feedback during past 60days
- have opened dispute twice in past 60days.
Delivery will not be make even if the order placed by those buyers.We believe that all problems could be fixed by communication between buyers and sellers as long as both of us are honest and understanding.
