Daikin EWAP460MBYN [270/452] Dicn network overview

The Functional Controller for DICN ESIE05-07

2–74 Part 2 – Functional Description

3.2 DICN (network): Overview

Introduction DICN = Daikin Integrated Chiller Network

Also referred to as master-slave system.

Remark: In a DICN system (Master-Slave), all the pCO

-controllers must have the same software,

code, bios, and boot version!

Function

description

To activate the DICN function MS Option must be set to "Yes" in the service menu. In the user settings

menu of the master it must also be specified how many slave units are connected.

When activated, this function will transfer all parameters to the different units through pLAN

communication line.

In DICN setup (when MS option is yes): the different units can be put in "normal" or "standby" mode

or in disconnected ON / OFF mode. When the mode is disconnected the unit selected will operates

as standalone units.

Remark: If the master is down (= no power) then a network safety is activated and all units will work

as standalone (no parameters are transferred), and they will work with their own setting in

the controller.

Overview of

possibilities

Basic principles:

P No ER-units in a DICN-system.

P Possible to combine all air-cooled chillers (including HR options and Fan inverter options:

EWAP110~540MBYNN/EWTP110~540MBYNN.

P Possible to combine all water-cooled chillers: EWWD120~540MBYNN.

P Possible to combine all remote condenser water chillers: EWLD120~540MBYNN.

P Max to combine 4 units in one DICN-system.

Important:

P It is not possible to combine pCO

and pCO

controllers in one DICN system.

P It is not possible to combine step and stepless compressors in one DICN system.
