Safety Guidelines, Warnings and Cautions
Read and understand the following guidelines to ensure safe installation.
This equipment is to be installed by an accredited electrician
or equivalent technical person, as per these installation
instructions.
Read the installation instructions before connecting the system
to the power source.
All electrical work must be performed by a licensed technician,
according to local regulations.
Ultimate disposal of this product should be handled according
to all national laws and regulations.
Installation of the equipment must comply with local and
national electrical legislation for the installation of electric
equipment.
Do not install the devices outdoors or exposed to direct solar
radiation, water, high relative humidity, or dust.
Install the equipment only in a restricted access location.
When wall mounting, be sure to x rmly on a stable surface and
in accordance with the instructions below.
Failure to follow these WARNINGS may result in injury or death
When DIN rail mounting, x the devices properly to the DIN rail
following the instructions below.
When mounting on DIN rail inside a metallic cabinet be sure to
properly connect to the ground.
Unplug from power when connecting the wires.
Pay attention to the polarity of power and communication
cables during connection.
Disconnect power of any bus or communication cable before
connecting the system.

4
Cautions
Failure to follow these CAUTIONs may result in serious injury.
Do not allow children to play with the CoolPlug or CooLinkHub.
Do not disassemble, modify, or repair the CoolPlug or
CooLinkHub. Unauthorized modications or repairs may result
in electric shock or re. For support, contact CoolAutomation.
Do not expose the CoolPlug or CooLinkHub, to moisture.
Water can damage the CoolPlug or CooLinkHub resulting in an
electrical components failure, electric shock or re.
Do not use ammable materials (e.g. hairspray or insecticide)
near the CoolPlug or CooLinkHub. Do not clean with organic
solvents such as paint thinner.
Use only a dry cloth to wipe if necessary. The maximum voltage
that can be directly applied to the CooLinkHub is 24V DC.
Do not plug into AC110V or AC220V.
DO NOT INSTALL the COOLINKHUB or COOLPLUG IN THE
FOLLOWING LOCATIONS:
a) Where mineral oil mist or oil spray or vapor is produced, such
as in a kitchen. Plastic parts may deteriorate and fall off.
b) Where corrosive gas, such as sulfurous acid gas, is produced.
c) Near machinery emitting electromagnetic waves.
Electromagnetic waves may disturb or damage the operation of
the CooLinkHub.
d) Where ammable gas may leak, where there is carbon
ber or ignitable dust suspensions in the air, or where volatile
ammables such as thinner or gasoline are handled. Operating
the CooLinkHub or CoolPlug in such conditions may cause a re.
e) In high temperature areas or near any ame.
f) In moist areas, or where there is exposure to water.

The CoolPlugs & CooLinkHub solution allows seamless
integration of Split, Multi-Split and Mini-Split HVAC
units with Home Automation, BMS and Smart IOT
products and services; or full control and monitoring,
using a standalone CoolAutomation cloud-based App
(ControlApp).
Once connected, it allows full control of the indoor unit
including the following functions: on/off, operation
mode (cool/heat/fan/dry/auto), set points, adjust fan
speed and activate swivel.
The solution allows bidirectional communication with
the indoor unit for receiving error codes from the unit as
well as feedback about actual status of the HVAC unit.
CoolPlug connects directly to the HVAC indoor unit on
one end, and to the CooLinkHub on the other.
CooLinkHub - aggregates multiple CoolPlug devices
and provides wide interface options for controlling and
monitoring each of the CoolPlugs, either over the wired
network (PBUS) or a proprietary wireless mesh network.
CoolPlugs and CooLinkHub
System Overview

6
The PBUS is CoolAutomation's proprietary Bus, running on a shielded twisted pair cable (20-24AWG).
The PBUS utilizes daisy chain network topology. No loops are allowed.
Up to 10 CoolPlugs can be connected to a single CooLinkHub.
Wired connection - PBUS (PlugBus) Topology

7
WRLS Cool Plugs and WRLS CooLinkHub communicate with each other using CoolAutomation's 2.4 GHz proprietary and secured
mesh network.
Each WRLS CooLinkHub creates a network and automatically connects to all paired devices within this network (WRLS CoolPlugs).
Paring of the WRLS CoolPlugs with the specic WRLS CooLinkHub can be factory pre-set (prior to shipment) or congured locally
(please refer to pairing instructions at page 35).
Up to 10 CoolPlug devices can be connected to a single CooLinkHub.
The recommended distance between each of the two devices (CoolPlug/ CooLinkHub) is up to 20m (50 ft) line of sight. Please
note, that concrete walls, ceilings and other types of obstacles or noise caused from electro-magnetic elds (generated by power
cables or other sources), can signicantly impact signal strength and will result in reduced distance.
The network topology is a mesh type network, meaning that each device acts as a receiver and a transmitter, and repeats the
signal. For planning purposes, make sure you have connectivity between each of the two devices (CoolPlug with its neighbor
CoolPlug, or CoolPlug with the CooLinHub).
Wireless connection - PBUS (PlugBus) Topology

CoolPlug models are HVAC manufacturer specic. Each CoolPlug has a small round sticker with letters on its back (DK, DKS, etc.)
indicating the HVAC manufacturer that the CoolPlug is compatible with.
