Communication Interface Options
Percent capacity output
The controller provides an analog voltage output
(0-10 VDC) to communicate active unit capacity [%].
This signal is available on option module 1A4, Terminal
block J2 – Y1, identified on the wiring diagram as S1.
General
WARNING Ground wire! All field-installed wiring must
be complete by qualified personnel, and comply with
the local codes and regulations. Failure to follow this
instruction could resut in death or serious injury.
Field wiring for the communication link must meet the
following requirements:
• All wiring must be in accordance with local codes and
regulations.
• Communication link wiring must be shielded, twisted
pair wiring (Belden 8760 or equivalent), below table
provides recommendation for wire size selection:
• The communication link cannot pass between
buildings
• All units on the communication link can be connected
in a “daisy chain” configuration.
Note: to prevent control malfunctions, do not run low
voltage wiring (< 30 V) in conduit with conductors
carrying more than 30 V.

LonTalk Communication
Unit chiller controller provides integrated LonTalk
communication between chiller and the Building
Automation System (BAS). The input/outputs include
both mandatory and optional network variables
as established by the LonMark Functional Chiller
Profile 8040.
Installation Recommendations
The Lon interface uses an Echelon FTT-10 transceiver,
which is approved to be used on the TP/FT-10 channel.
This channel is characterized by the following main
features:
• It consists of up to 60 nodes on a single network
segment
• Data rate : 78 125 kbps
• Maximum distance : 1400 meters
• Recommended topology : daisy chain with double end
terminator (105 ohms)
For futher details, refer to the official documentation
LonWorks® FTT-10A free topology transeiver user’s
guide and to the official LonWorks® guidelines
LonMark® layer 1-6 interoperability guidelines
version 3.0.

available on the internet site www.lonmark.org
BACnet Communication
Unit chiller controller provides integrated BACnet
communication between chiller and the Building
Automation System (BAS).
ModBus Communication
Unit chiller controller provides integrated ModBus
communication between chiller and the Building
Automation System (BAS).
pCOWeb Communication
Unit chiller controller provides integrated pCOWeb
communication between chiller and the Building
Automation System (BAS).
