NO

General enable:

Off General

Plant

Display of the general system state:
—  Enabled: the system regulates via the main probe based on the system setpoint;
—  Off due to alarm: system off due to serious alarm;
—  General off: system turned off by general enabling (see the paragraph de-

scribed below "General enabling”);

—  Off by BMS: system turned off by the supervision system;
—  Off by clock: system turned off by time bands;
—  Off by dig. input: system turned off by digital input (ID17);
—  Off by display: system turned off by terminal, control system screen;
—  Off by master: system turned off by master in master/slave configuration;
—  Out of operating limits: system out of machine operating limits;
—  Replacement boiler: replacement boiler active;
 
It is possible to change the unit state in the last row. If NO is selected, the entire 
system will be put in stand-by mode, if YES is selected the machine is turned on.
