1. OVERVIEW
ems (energy managementsystem)controllers from elstatare usedinavariety of drinks coolers, optimisingenergy
savings, withoutcompromisingondrinks servingtemperature.
Arange of controllers are available to suit applications such as:
• Singledoorcoolers
• Doubledoorcoolers
• Openfrontcoolers
• Vendingmachines
• Sub-zerobeercoolers
1.1 About this reference guide
The purpose of this guide is toexplainindetail all informationregardingelstatcontrollers includingthe user interface,
parameters, accessories andtroubleshooting.
Complimentary informationis alsoavailable from elstatsuchas accessory lists, accessory datasheets andsingle shee-
tuser guides.

The ems25 series consists of the ems25, ems25+, and ems25advanced. The ems25 series is designed as a compact
alternative the ems55 series.
2. What is the ems25 series?
Feature Desicription
User and diagnositc information
3-digit, 7-segment display (ems25+ and ems25advanced only) and push
buttons that display the product temperature and other information such
as defrost or teach and alarm conditions. Also, enables 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. ems25+ and ems25advanced only.
Motion detection A remote motion sensor enables ems controllers to detect activity when
someone moves in frontof the cooler.
Door open detection Adoor switch enables ems controllers to detectcooler activity when
someone opens the cooler doors.
The ems25 series with the suitable accessories also provide the following functionality:
The ems25 series controllers switch the following cooler components:
Feature Desicription
Compressor ems controllers switch the compressor to manage the temperatire of the
refrigeration compartment
Evaporator fan ems controllers switch the evaporator fan to manage the evaporator fan.
ems25advanced only.
Lights ems controllers switch the cooler lights to save energy.

2.1 Water ingress–advisory informationforF MEA analysis
Elstat products have been designed to minimise any risks associated with water ingress and all controllers are IPX5
certified.
The OEM or installer is responsible to ensure that local/country laws andregulatory requirements are met.
2.2 ems25+ andems25advanced userinterface
The user interface of the ems25+ and ems25advanced is as follows:
Indicator Functon Colour
1Saving temperature
disable
on if the saving mode temperature is disabled.
The controller maintains ready mode temperature at all times Red
2 Motion on when motion is detected Red
3 Compressor on when the compressor is running Green
The ems controller buttons access the menu to view parameter values, reset the ems controller, and to run test
routines.
Push buttons:
Button Name Functon
defrost
or
teach
ems25advanced: starts a defrost cycle.
ems25+: sets the ems controller to the daving mode for up to one
hour.
Set Selects menu options and scrolls through the parameters
Up Increases the parameter values.
ems25+: Also exits the tech saving mode
Down Scrolls down menus, decreases parameter values, and cancels
alarms
