Functional Description

Introduction This part gives more detailed information on the functions and controls of the unit. This information is

used as background information for troubleshooting. An extensive overview of the functioning of the

controller is also given in this part. Knowledge of the controller is essential to gather information prior

to servicing and troubleshooting.

The functional control description is split up in two chapters, one concerning the standalone units and

a second one concerning DICN setup. The DICN is the Daikin Integrated Chiller Network, also known

as Master Slave Option. When we talk about operating as a standalone unit we mean a standalone

unit (MSOption = "NO") or a unit in DICN (MSOption = "YES") but set to mode disconnected. When

operating in DICN setup we mean with MS Option set to "YES" and Mode set to "Normal" or "Standby".
