1. CONTROLLER WITH INTELLIGENCE
The Nexo controllers are the rst truly
intelligent refrigeration solution for
the beverage industry that delivers
consumer insights from eld data to
optimize and take complete control of
cold drink marketing.
Elstat’s game-changing Nexo platform
is a powerful tool that connects drink
brands directly to consumers at the
point of sale, wherever they are in
the world, to create sustainable and
protable relationships.
The energy management system (ems) controllers from Elstat are used in a variety of drinks coolers,
optimising energy savings, without compromising on drinks serving temperature.
The CMS100 Nexo controller is designed for applications such as single door coolers, double door coolers
and vending machines.
1.1 Functionality
Feature Description
User and
diagnostic
information
3-digit, 7-segment display that displays the product temperature and other information
such as defrost or teach and alarm conditions. Also push buttons, that enable the end-
users to cancel alarms and service technicians to run test routines.
Product
temperature
An appliance sensor measures temperature of the refrigeration compartment. EMS
controllers use the refrigeration temperature to manage the product temperature.
Refrigeration
system high
temperature alarm
An optional condenser sensor measures the temperature of the refrigeration system.
EMS controllers use the temperature to alert to problems such as blocked condensers.
Motion detection A remote or integrated motion sensor enables EMS controllers to detect activity when
someone moves in front of the cooler.
Door open
detection
A door switch enables EMS controllers to detect cooler activity when someone opens the
cooler doors.
The controllers switch the following cooler components:
Feature Description
Compressor EMS controllers switch the compressor to manage the temperature of the refrigeration
compartment.
Evaporator fan EMS controllers can control the evaporator fan.
Lights EMS controllers can control the cooler lights to save energy.

1.2 User interface
All Elstat controllers are made from food grade materials and are safe for internal installation. The
CMS100 controllers are available with either an integrated or a remote motion sensor.

This variant should always be installed where the
sensor can ‘see’ activity. It is recommended that the
controller is installed externally on the cooler.
This variant of the controller can be installed
internally on the cooler but the remote motion
sensor must be installed where it can ‘see’ activity.

1.4 Mounting
CMS100 Nexo
controllers are
designed for panel
mounting and are
secured using four
countersunk self-
tapping screws.
The aperture
and screw pitch
dimensions are as
shown.
Note
The Water Ingress Protection ratings (IP ratings) are only valid when the product is
mounted in the recommended orientation shown below.
Failure to follow these guidelines will invalidate the designed levels of Ingress Protection
and any subsequent damage incurred will not be covered under the warranty terms.
In addition, incorrect installation may result in the following conditions:
`If mounted vertically with the integrated
motion sensor close to the oor, the motion
sensor may not be able to detect motion
eectively.
`If mounted vertically with [parameter
programming port] close to the oor, water
ingress may occur.
`If mounted too close the oor, water ingress
may occur at the mains or line voltage
terminals.
Cable routing to the CMS100 controller is critical as water can trace
or follow the cable downwards.
Therefore, immediately prior to the connection to the controller, a
drip loop must be formed in all wiring as shown.
An appropriate level of protection must be given for the eects of
water ingress due to condensation, product spillage, and so on.
Note
Cable routing looms must not be secured to hot pipes or vibrating components. Secure
cable routing looms with clips where ever possible.
Ensure that the back of the controller is protected from the possibility of unauthorized
tooled access with an appropriate strain relief on cables.

1.6 Programming port cover
When accessing the programming port on
the controller fascia, remove the rubber
cover and let it hang on the attaching strap.
This will prevent misplacing the port cover.
Note
Do not remove programming port cover fully. Detaching the cover from the controller
fascia can damage the attaching strap.
On completion of controller
programming, ensure that the
programming port cover is replaced
inserting the left edge rst then
securing the other edges in place
moving in clockwise direction.

1.7 Wiring diagram
Note
To remove the potential for damage occurring to, and the potential for failure of,
the crimped connection on the mating half of terminals 1 to 4 of the CMS100 Nexo
controller it is recommended that only right angle insulated 6.3mm tab connectors,
complete with strain relief, are used to terminate these cables. Use of straight
connectors may exert excessive pressure on to that connector.
