CA0 Solar Commercial Controller

1.Touch screen, embedded system; 2.Control thermal system; 3.Password Protection; 4.Monitoring system; 5.Customized program.

This controller is preprogrammed for commercial or larger residential systems with tank capacity less than 3000 liters. The system can be natural, as in thermosyphon, or pressurized forcing circulation.  The controllers provide simple solutions to control more complex arrangement needs in stores, small shops, or residences. These include temperature differential controls to activate/deactivate the solar loop pump to transfer heat to the storage tank; an alternative heating energy source controller, which can be an energy source provider of electricity, gas, or other fuel, to regulate a boiler or resistor functioning to heat water in the storage tank, if the solar system is unable; frost protection; storage tank level monitoring; and system fault localization.
