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.

Waiting on the calibration
NOTE
■
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).
