The BMS writes heat demand, the system setpoint (guarded by a countdown failsafe timer), outdoor-reset settings, DHW setpoint, clock, and flow or boiler-count limits as analog and binary values. Read-only analog inputs give plant temperatures, boiler counts, BTU/h, system flow and per-boiler run time, cycles, temperatures, modulation and local flow; read-only binary values give interlock, alarm and status flags for each of up to 16 boilers.",
