Line no. Operating line
7150 Simulation outside temp
To facilitate commissioning and fault tracing, outside temperatures in the range from –
50 to +50 °C can be simulated. During simulation, the actual, the composite and the
attenuated outside temperature are overridden by the set simulated temperature.
During simulation, calculation of the 3 mentioned outside temperatures continues and
the temperatures are available again when simulation is completed.
The function is deactivated by setting - - on this operating line, or automatically after a
timeout of 5 hours.
