 "summary": "The boiler version of the PVI EOS BTCII control serves BACnet MS/TP (or Modbus RTU) from the master boiler's display. Besides boiler 1's probes, ignition state, modulation, relays, flame current, counters and error code, it gives the system (cascade) status, installed/talking/enabled boiler counts, the modulating and lead boiler, and writable system enable, BAS setpoint, setpoint and boiler enable. In a cascade the BAS connects only to the master.",
