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.
