Part 2

3 The Functional Controller for DICN

3.1 What Is in This Chapter?

Introduction The functions that will be described in the next chapters are basically the same as those that were

described in previous chapters. Therefore the details and the description of the function itself will not

be described again, but only the specific difference that occur when the units are used in a DICN setup

(DICN = Daikin Integrated Chiller Network).

By DICN setup we mean MS Option is yes and the mode is "Normal" or "Standby".

Understanding these functions is vital when diagnosing a malfunction, which is related to functional

control.
