1. INTRODUCTION
The ERC 102 is an electronic refrigeration controller with an LED display especially developed for bottle
coolers and commercial fridges and freezers. It is particularly suited for OEM customers where time, easy and
reliable installation and high quality need to go hand in hand with flexibility.
The latest generation CPU, plenty of memory and high-end electronic components allow for a uniquely
versatile software. Three separate password-protected user levels can be used to control more than 200
different parameters to fit all individual requirements.
ERC 102’s IP rated body, advanced materials and internationally approved hardware design open it up for use
in almost any climate globally, indoors as well as outdoors.
Laboratory work with ERC 102 is rendered easy and flexible. Danfoss KoolProg software with a USB-powered
gateway accelerate programming; on the OEM assembly line, just one Danfoss unique Docking station can
easily program up to 3,000 controllers a day – at zero inventory cost.
It uses a globally-compatible, lightweight, switch mode power supply.
All components have been carefully selected to help reduce the CO2 footprint. The globally-compatible
internal power supply uses an average of just 0.7W – 4 times less than an average controller today.
Sensors include ambient light for display brightness, which also detect shop opening hours for
energy-saving routines. Door and temperature sensors provide input for controlling the compressor,
the light, the fan and automatic defrosting.

2.3 Connections
Programming an individual unit in a laboratory:
the USB gateway requires KoolProg Software
running on a PC. It enables parameters to be set in
real time and an array of status information to be
read (bidirectional connection). This method is used
to determine the correct parameters during R&D.
Once the desired settings have been determined,
a KoolProg ERC specific parameter file is saved to the
EKA183 USB copy key for later mass programming.
The USB Gateway is a laboratory tool, offering fast
and easy programming of any ERC102 controller.
KoolProg software installation is provided;
the gateway is standard inventory for OEM labs.
Mass programming on an assembly line:
the docking station is used for high volume
programming of ERC controllers, for example
on an assembly line. The docking station is a
write-only device.
See above (Programming an individual unit) for
preparing the EKA183 USB copy key, which is to
be inserted into the docking station. The settings
are then loaded into each successive controller
in a matter of seconds.
KoolProg software is not required for mass
programming.
Note: please refer to the koolprog manual for more
details about programming.
KoolProg: is the software from Danfoss for
programming the ERC 102 via a USB cable and
a PC rather than with the front panel buttons.
Please refer to the KoolProg manual for details.

3. OVERVIEW OF THE PRODUCT
The ERC 102 is a state-of-the art, IP65 (front)-rated
refrigeration controller for use in both Glass Door
Merchandising and Commercial Fridges and Freezer
applications.
With four inputs and four outputs, powerful
algorithms and input from multiple sensors, the ERC
102 delivers both energy-saving routines and
compressor, light, fan and defrost control.
Together with the Danfoss docking station,
programming of pre-prepared parameter sets can
be achieved in just five seconds. There are over 200
parameters (see Chapter 7) including innovative
features such as night mode detection,
store opening detection, door open alarm control
and display dimming for restaurants.
The ERC 102 can also be programmed via USB using
the Danfoss KoolProg software, allowing the most
suitable parameter findings to be found quickly
during the application development process.
It is also possible to operate and program the
controller using the control buttons (only when
actually installed in a refrigerator / freezer).

02 6. CONFIGURATION OF INPUTS AND OUTPUTS
The ERC 102 inputs and outputs are configurable by
tionallity:
the customer. Before getting started it is a good idea
to check if all inputs are configured correctly and
match the sensors attached.
mode Input and output configuration settings are part of
the assignment menu (ASi).
For instance: Danfoss supplies only 2-pole defrost
sensors, so input S3 will most likely be used as a
defrost / evaporator temperature sensor input.
Please contact your local Danfoss representative for
information about default settings.

NOTE: Coded sensors will impact on the number of
possible configurations.
Assignments / ASi
6.1 Changing input and output configuration settings

7. PARAMETERS
This chapter details all user-accessible parameters
in ERC 102 software 5.05.
The access level can be set separately for each
parameter using KoolProg software. There are three
levels of access – 1, 2 and 3. Level 1 is for shop access,
level 2 for technicians and level 3 for OEMs. The access
levels cannot be set using the buttons. Passwords for
the different levels can however be altered for the
level of access you have – for example a level 2 user
can change the password for level 1 and level 2 but
not level 3.
NOTE: Incorrect parameter settings can lead to
inadequate cooling, excessive energy consumption,
unnecessary alarms and in the case of temperaturesensitive food storage, breaches in food hygiene
principles and regulations. Only a trained operator
should make changes to parameters.
tionallity:
INFO! Some parameters may be hidden to you. When
scrolling through menus, the parameters available will
mode have been pre-determined using KoolProg software.
Your access level will determine which parameters you
can view and edit.

ERC 102 Reference manual – 8 TYPICAL APPLICATIONS – WIRING DIAGRAMS
APPENDIX V: APPLICATION SPECIFICATON
V.1 Control sensor
The control sensor must always be connected and
is used for controlling the cut-in and cut-out of the
compressor according to the set-point. The sensor is
also used for the displayed temperature.
Placement of sensor:
Vertical coolers with fan
Most common placement is in the return air to the
evaporator. The sensor can be placed close to the
fan – even when the fan is pulsed during compressor off periods: The updating of the temperature is
blocked when the fan is stopped and only updated
when the fan has been running for a while, so that
the heat from the fan does not affect the temperature reading.
For applications sensitive to sub-zero temperatures,
sensor placement in the evaporator outlet air can be
considered.
Vertical freezers with fan
Placement in the return air or in the freezer
compartment
Coolers without fan
the best results are normally obtained when the
sensor is placed at the side-wall, 10 cm from the
back and approximately at 1/3 from the bottom or
where the evaporator ends.
The control sensor must always be connected and
is used for controlling the cut-in and cut-out of the
compressor according to the set-point. The sensor is
also used for the displayed temperature.
ERC 102 Reference manual – APPENDIX V: APPLICATION SPECIFICATION
57
V.2 Evaporator sensor
The evaporator sensor is only used for de-icing of
the evaporator and has no control purpose.
Placement of sensor:
Place the sensor where the ice melts last.
Please be aware of that sharp finns can damage the
cable.
V.3 Condenser sensor
The condenser sensor is used to protect the compressor against high pressure when the condenser is
blocked or the condenser fan fails.
Placement of sensor:
Place the sensor at the liquid side of the condenser.
Use a metal bracket or metal tape to ensure good
thermal conductivity. Be sure that the cable does not
pass hot spots at the compressor or condenser that
exceeds 80°C.
58
ERC 102 Reference manual – APPENDIX V: APPLICATION SPECIFICATION
V.4 Ambient light sensor
The ambient light sensor is used to detect opening
hours of the shop.
Placement of sensor:
The sensor must be placed so that the interior light
does not affect the sensor.
Possible placement could be in the front of the
cooler or at the top.
V.5 Door sensor
The door sensor is used to detect buying activity and
to stop the fan when the door is opened.
Danfoss does not supply the door-switch. Use the
door-switch you have and connect it to the cable
supplied by Danfoss.
