The BMS can enable the unit, command occupancy, reset alarms, write temperature, dehumidification, economizer, airflow and static pressure setpoints, take over fans and the outdoor air damper, and replace hardwired sensors with BMS values while a watchdog is kept alive. Read-only objects cover temperatures, humidity, pressures, refrigerant circuit values, outputs, unit status mode, latest alarm and bit-packed status and alarm words.",

  "heartbeat": "BV 1 BMS_Watchdog must be toggled by the BMS within the timeout delay whenever the BMS replaces a hardwired sensor (or takes over fan speed or damper control). If the timer expires, the controller alarms (BMS Offline) and falls back to its hardwired sensors and local control until the BMS returns. The watchdog status is shown on a read-only BV.",
  "remote_sensors": "Set the matching source-select BV to BMS, then write the *_from_BMS analog value (e.g. AV 27 outside temperature, AV 35 space temperature).
