Central Operating Mode
Overview
The Central Operating Mode Determination passes central commands from PXC con-
troller or Desigo CC Scheduler and distributes them to DXRs located in the building
zones.
The application receives operating mode commands (inputs) either
• From Desigo CC via BACnet command (normally priority 8 or 13). It overwrites
the other input sources.
• From a clock timer with switching output, switch or relay contact (Prio 16). The
function is only active if no scheduler and no manual operation is active.
• From a scheduler on PXC Controller (Prio 15)
• As an option, the Application Function receives a request for night cooling, free
cooling, and a switching signal from the AHU.
