2. Scroll to Parameter 803 and set its value to 16. This allows Control via Modbus such as
via AERCO ACS or BAS/EMS.
3. Scroll to Parameter 816 and set the Modbus address for this BCM.
Once the desired address has been set on each BCM, the Modulex Boiler is configured for
Modbus Network control by the controlling Master EMS/BAS or AERCO ACS. For the BCM to
automatically act as the Back-Up Controller if the Modbus Master signal is lost, Parameter 376 of
the BCM must be set to 3 and a jumper must be installed on terminals TA/9 of connector Y2 (see
section 6.3.2 for details)
See Chapter 8 and GF-124 Chapter 2 for Modbus points for the BCM and ACS.
