Shut-down for Maintenance
The air conditioner can be switched off, e.g. for maintenance work, using BI or the
BACnet object. In this case, the shutdown sequence is started and the system
performs a controlled shutdown. The stop sequence is executed by activating the
input PrtOpModRIn or the BACnet object PltShD. These functions override all other
influences except the emergency control, protection control and operation via BI.
