After strong temperature fluctuations it can take a long time until the device
acclimatises and has constant values. This could be the case after a new
installation, for example. A half hour calibration time is not unusual in this
case.
The flashing of the values for "°C" and "RH" stops when the self-heating
process of the device has concluded.
When the threshold values are exceeded, the display is illuminated red.
–
When the threshold values drop below their set value, the display is
illuminated again in white.
If the status of the relay is altered by hand, it is retained for the duration of
the switch-off delay. Then the status of the relay switches back into the
correct status (after the measured values and threshold values).

After a reset or a mains failure the device
re-calibrates itself automatically. When
the first reliable measured values are
available, the device switches to the
standard display.
