Control for a dual heating system determines the optimum operation using a fossil fuel or solar energy according to current conditions

摘要

The control for a dual heating system, which uses fossil fuel to generate heat and also uses solar energy for heating, has a display to show the operating parameters and the assembly functions and/or a remote control at the heated space. Overlaid values are registered and displayed from the current operating values, for the function and effect of the whole heating assembly and/or a section of it, or for evaluation.
