D. OPERATING DESCRIPTION
The existing regulation controls all the circuits of the installation. It determines the outlet set
point temperature that the installation requires and sends it to the boilers, either in a 0 - 10V
signal directly to the NAVISTEM B3100 that is the master of the cascade, or over the LPB bus
or Modbus to each NAVISTEM B3100.
The cascade of boilers is controlled by the installation’s regulation system according to the
needs.
The setpoint sent reflects the heating temperature that the installation needs at this precise
moment.
