General Description
The CoolLogic Touch Control System provides leaving
chilled and hot water liquid temperature control algorithms
which maintain precise temperature control for cooling,
heating, heat recovery and simultaneous heating and
cooling applications. A compressor run time equalization
sequence is given to ensure even distribution of compressor
run time throughout the entire chiller bank. Chiller power

interface for all levels of setting and retrieving data.
The module controller resides at each module location

Safety
Throughout this manual warning, danger, caution and
attempting any installation, service or troubleshooting
of the equipment. All labels on unit access panels must
be observed.
DANGER

CAUTION
practice which, if not avoided, could result in minor or
moderate injury or product or property damage.
Introduction
WARNING/ADVERTISSEMENT
To avoid possible injury or death
due to electrical shock, open the
power supply disconnect switch and
secure it in an open position during
installation.
Pour éviter les blessures ou la mort
par électrocution, ouvrir la interrupteur
de sécurité et xez-le en position
ouverte lors de l’installation.
WARNING/ADVERTISSEMENT
Disconnect power supply(ies)
before servicing. Refer servicing
to qualied service personnel.
Electric shock hazard. May
result in injury or death!
Debrancher avant d’entreprendre
le dépannage de l’appareil.

CAUTION/ATTENTION
Use only copper conductors for eld
installed wiring. Unit terminals are
not designed to accept other types of
conductors.
Utilisez uniquement des conducteurs en
cuivre pour le câblage. Bornes de l’unité
ne sont pas conçus pour accepter
d’autres types de conducteurs.
WARNING/ADVERTISSEMENT
For eld installation of Port 1
communication wiring, installer must
use:
• ARC-156 communication wire
• single-twisted pair
• shielded with drain
• low capacitance (12.5 pF/ft)
• 22AWG
This conductor must be daisy chained
from the CoolLogic Controller to each
chiller module.
Maximum separation of low voltage
communication and high voltage
power wiring is required.
The communication cable must be
installed in its own conduit. Routing
must enter and exit the low voltage
section of the control box where the
controller is located and should not
be ran parallel to, or any closer than,
6 inches from any high voltage AC or
DC wiring either inside or outside of
the machinery compartment.
(See IOM or contact ClimaCool for
complete specication.)
Pour l’installation sur place du
câblage de communication du port 1,
l’installateur doit utiliser:
• le câble de communication ARC-156
• Paire à simple torsion
• blindée avec drain
• faible capacité (12.5 pF/ft)
• 22AWG
Ce conducteur doit être connecté en
guirlande du contrôleur CoolLogic à
chaque module de refroidissement.
Le l doit être installé dans son propre
conduit. L’acheminement doit entrer
et sortir de la section basse tension
du boîtier de commande où se trouve
le contrôleur et ne peut pas circuler
à moins de 6 à 8 pouces de tout
câblage de tension CA à l’intérieur
ou à l’extérieur du compartiment des
machines.
