Troubleshooting
When you leave the commissioning menu, the universal controller checks whether
the room and the supply air temperature sensor are connected and then responds
as follows:
Room and supply air
temperature sensor
present?
•
If, at that time, the measured values of room and supply air temperature are
available, but are missing later, a sensor error message is delivered and
presented on the display:
–
"Xx ---"
=> sensor missing
–
"Xx ooo"
=> short-circuit
•
If, at that time, the measured value of the room temperature is missing, the
supply air is controlled to the adjusted room temperature setpoints
•
If, at that time, the measured value of the supply air temperature is missing, the
plant will be shut down (MAINALM)
