SG Ready 1 Input SG Ready 2 Input Description<br />
0 V 0 V The system works with the normal logics, without any impact from the Smart Grid<br />
function.<br />
230 V 0 V The electrical loads (heat pumps and heating elements) are disabled. The external<br />
resources are enabled in heating mode but not in cooling mode.<br />
0 V 230 V For domestic hot water production, in time scheduling, the set-point is set to Comfort<br />
in the reduced-rate band. If the DHW charge has been completed or if there is<br />
no DHW storage indirect cylinder, the buffer indirect cylinder set-point is increased/<br />
decreased in heating/cooling mode by a value defined by parameter 20.4.4 Buffer<br />
electric integration offset. Therefore, if the buffer mode is not active, the SG function<br />
will manage the room heating cycle so as to store the available energy. In this case,<br />
all zones with time scheduling that are currently in the reduced-rate band will be<br />
regarded as Comfort zones.<br />
