It covers burner phase, lead/lag role, modulation, combustion fan drive and O2 sensor data, water temperatures, safety switch states, alarms and pump/isolation valve status. The BMS can enable the boiler, send a water setpoint and a heartbeat, and supply header, outdoor and DHW temperatures when the boiler is set up for them.",
