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 will be 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 1 hour.

The input / output test is used to check the correct functioning of the connected
components.
When selecting a setting from the relay test, the relevant relay is energized, thus
putting the connected component into operation. The correct functioning of the relays
and wiring can thus be tested.
Important:
During the relay test, limitation of the boiler temperature by the electronic control
thermostat (TR) remains activated. Other limits are deactivated.
Selector sensor values are updated within a maximum of 5 seconds.
The display is made with no measured value correction.
