rement
The temperature probes are precise to
± 1 °C. If other
units with temperature display are operated, the
displayed temperature values may differ from one
another by up to 2 °C.
− Recommendation: The arithmetic mean of all
displayed values produces a useful approximation of
the actual temperature.
− Greater deviations are possible if the units are
exposed to direct sunlight. For this reason, ensure
that the unit is installed such that it is protected from
direct sunlight.
