During scheduled operation (clock), the state indicator (a 
white arrow) will show you the control mode of the selected 
circuit. The white arrow will blink when this is a heating 
circuit and it is in the optimizing period.
The mode can be set differently for each circuit by means of 
the function selector. However, if manual operation (hand) is 
chosen, this mode will apply to all circuits.
