3.3 Thermal Solutions Boiler Control (TSBC) and Sage Boiler Control (SBC)
• The Modbus communication connects to the same RJ11 port that is used by the boiler-to-boiler
communication.
• Connect one end of the RJ11 cable to the TSBC and cut off the other end of the cable to access the individual
wires of the RJ11 cable. Wire the RJ11 cable as shown above.
