Professional controller for solar multifunctional and designed for different tasks to control besperboynoy operation of solar systems for different purposes, providing additional heat generation due to automatic time control of the system, as well as work tselbyu electricity. All controllers are numerous tests for tightness and strength, which eliminates the possibility of marriage. Controllers highly intellectual and can design solar systems of any complexity. The product is versatile, reliable, "intuitive control" and reasonable price.

SK868S9 controller allows to set separately the power section (power and temperature sensors) and display controls. This allows to place the contact-force portion of the controller in the most appropriate place in terms of installation, service, control logic or switching between the elements of the system (typically boiler or furnace), and the display in turn, in the most convenient place for the user (Hall , bathroom, bedroom).
