8.4.4 Outside temperature simulation
To simulate the outside temperature and test the response of the plant, the
measured value of the outside temperature can be overridden.

During simulation of the outside temperature, message "Outs sensor simulation
active" appears.
No. Text Effect
12 Outs sensor
simulation active
Non-urgent message; must not be
acknowledged
This message remains active until "Simulation " is returned to "----". This ensures
that the simulation is always completed.
The simulated outside temperature is used only locally; it is not sent via bus to
other controllers.
8.4.5 Troubleshooting
When you exit the "Commissioning" menu, a check is carried out to see if the
outside temperature is connected. If the outside temperature is connected at this
point and missing later, message "[...X...] sensor error" appears.
For each system, only one outside temperature can be sent within the same zone
(only one outside temperature master).
If several controllers send outside temperatures within the same zone, message
">1 outside temperature sensor" appears. The fault is sent by the controllers
sending and receiving outside temperature signals to and from the same zone.
If the controller expects an outside temperature signal via the bus and the signal is
not sent, message "Outside temperature sensor fault" appears.
