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
