4.5.19 Connection intelligent controller
(Smart Grid - SG)
Once the function is activated by parameter [SMART GRID] = 1
(see operating manual for the control unit), depending on the sig-
nal from the energy supply company, the heat pump is switched
to Stand-by, Normal or an operating mode with higher tempera-
tures.
To do so, the potential-free contacts SG1/SG2 of the intelligent
controller must be connected to the J8 plug, connections Smart
Grid and EVU, on the RoCon BM1 circuit board (see fig. 4-43).
