READOUT IN THE DISPLAY
By default, the first line of the display shows
the relative humidity.
The second line shows the information about
the switching status of the relay (as a circuit) on the left,
and the respective switching value in % r.H. on the right
(switchpoint adjustable by potentiometer,
factory setting 75 % r.H.).
○
Circuit, empty = relay in idle state
●
Circuit, full = relay energised
