Functional Upgrades
The EJ1C-EDUC-NFLK (with connector terminal block) has been added to the End Units (EDU) and
the functions of previous models have been improved. Information in this manual related to improved
functionality is indicated with the
• Basic Units (TC4/TC2)
• Autotuning is provided for heating/cooling control.
• Self-tuning has been added.
• A switch can be used to display the output status on the operation indicators during operation.
• Modbus communications can be used to read and write all parameters, and to executed any of the
operation commands.
• A switch setting can be changed to use Modbus communications on port B.
• A switch setting can be used to set the baud rate of port B.
• A C0/80 status has been added for to the variable types.
• Up to eight G3PW Power Controllers can be connected to one Basic Unit.
Note 1. The G3PW can be connected to EJ1 V1.1.
2. The G3PW and G3ZA cannot be used together.
• Advanced Unit (HFU)
• Bit specification operation commands have been added to the parameters that can be specified for
programless download settings. This simplifies the program when operation commands are exe-
cuted.
• The G3ZA or G3PW Monitor parameter has been added to the parameters that can be specified for
programless upload settings. Up to four G3ZA Multi-channel Power Controllers or up to four G3PW
Power Controllers can be connected to one TC4/ TC2 Unit.
• The maximum number of parameters that can be specified for programless upload/download setting
has been increased from 600 to 1200 each.
• The maximum number of TC4/TC2 Units that an HFU can control has been increased from 16 to 32
Units.
• Communications unit numbers 32 to 39 can be used in the HFU via programless communications.
This allows the communications unit numbers of TC4/TC2 connected to an HFU to be numbered
sequentially, making it easy to copy HFU and TC settings to other HFUs and TCs.
• Support Software
Use version 4.10 or higher of the CX-Thermo when using the upgraded functions.
