The existing regulation system controls the installation's heating circuit.
It sends the outlet temperature set point to the boiler, either over the LPB bus through the OCI 345 interface
(SIEMENS protocol), or by a 0 - 10 V signal, sent directly to the NAVISTEM B3000.
When controlled by the external regulator, the boiler operates according to a sliding temperature scale
when it starts for the heating, according to the outdoor temperature.
