*) Notes for R32: R32 is classified as low flammable refrigerant in Europe. EC3-
X32 is designed under consideration of European safety standards and directives for
none flammable refrigerants. The use of EC3-X32 with R32 is for systems/regions
which it does not require consideration of additional safety standards as for
flammable refrigerant.
After selecting the parameters the EC3-X32 is fully functional without connected PC
or keypad/display unit ECD-002.

• A TCP/IP Controller Readme file is available on the
website to provide detailed information about TCP/IP Ethernet connectivity.
Please refer to this file if you need information beyond the contents of this
instruction sheet.
• Connect the EC3-X32 using the optional ECC-Nxx cable assembly or a standard
CAT5 network cable with RJ45 plugs assembly to a network or router that enables
the controller to receive a dynamic TCP/IP address or
• Connect the EC3-X32 to a computer using a crossover cable plugged directly into
the Ethernet port. In this case, the TCP/IP address of the computer must be
manually modified to be compatible with the default address of the controller.
Refer to the TCP/IP Controller-Readme file for more details.

(recommended method)
• Make sure that digital input is 0V (open), turn the power supply ON.
• Four parameters i.e. refrigerant type (u0), pressure sensor type (uP), valve type (ut)
and control mode can be set only when digital input is open (0V) while the power
supply is ON (24V). This feature is for added safety to prevent accidental damage
of compressors and other system components. All other parameters can be
modified at any time.
• The EC3-X32 has a TCP/IP Ethernet communication interface enabling the
controller to be directly connected to a network or a PC via the standard Ethernet
port. The EC3-X32 controller has embedded WebPages to enable the user to
visualize the parameter lists using real text labels.
• To view WebPages on the PC, a standard Web Browser like Internet Explorer® or
Mozilla Firefox and JRE Java Runtime Environment is needed. JRE can be
downloaded at no charge from the
• Open the Internet browser program on the computer and, if EC3-X32 is connected
directly to PC with a crossover cable enter the default TCP/IP address of the
controller (192.168.1.101) into the address line, or the dynamic address from the

Manual
• The Monitoring and Alarm WebPages are read only and therefore it is not
necessary to enter a username or password. A username and password will be
requested upon the initial request to any of the other WebPages. The factory default
settings are: Username: "EmersonID", Password: "12"
• The default settings may be modified on the Display configuration page.
• Press the tabs at the top of the Monitoring page with a left click of the mouse button
to enter the respective Webpage.
• The parameters will be visualized in real text together with the program code as
defined in the parameter list below.
• After the parameters have been modified, the complete list of settings can be saved
to the memory of the computer and used later to upload into another controller.
This can save a considerable amount of time when using multiple controllers and
over a period of time, a library can be created containing the parameter lists for
equipment for different applications.
• It is also possible to display live graphical data from the controller. Superheat,
evaporating pressure, coil-out temperature and evaporating temperature are
available on a 15 minutes rolling chart. Refer to the TCP/IP Controller-Readme
file for a complete description of the features available for the TCP/IP series of
controllers.
