2.7 CONFIGURING THE C-MORE CONTROLLERS
The C-More Boiler Controller can be set up for three types of Modbus (RS485) operating modes. These
modes are as follows:
• Monitoring and Configuration Only
• Modbus Direct Drive Control and Monitoring
• Modbus Remote Setpoint Control and Monitoring
The following subsections provide the procedures necessary to set up the C-More Boiler Controllers for
each of the above modes of operation. These procedures assume that the required wiring connections
for Modbus (RS485) operation have already been accomplished as described in subsection 2.6.
NOTE
The appropriate password must be entered in the Setup Menu of the C-
More Controller, prior to changing any of the current settings. Refer to
Section 2 of C-More Controller Operation Manual GF-112 for detailed
information on menu processing procedures.
2.7.1 C-More Controller Monitoring and Configuration Control
Each C-More Controller must be programmed with a distinct network address. The standard XPC
Gateway supports addresses 1 through 12 for C-More controlled boilers or water heaters. Contact
AERCO if additional addresses are required. Proceed as follows to program a valid address at each C-
More Controller:
1. Scroll through the Setup menu until Comm Address is displayed.
2. With Comm Address displayed, press the
CHANGE key.
3.
Using the ▲ or ▼ arrow key, enter a valid address between 1 and 12.
4. Press the
ENTER key to store the Comm Address in memory.
5. Repeat steps 1 through 4 for each C-More Controller on the Modbus network.
6. Upon power-up, the Gateway will begin to read C-More Controller information after its preliminary
checks.
