RHOSS ELECTA Series - Page 303

In addition to standard control, as described in the installation and operating manual, it is possible to subordinate supplementary generator start-up
(F-L terminals on the PCB-TERMINAL BLOCK) to system inertial storage temperature, installed between the generator (PdC and supplementary
generator) and the user systems (fancoil system, radiant system, DHW).
