9.2.14 To connect a Smart Grid
This topic describes 2 possible ways to connect the outdoor unit to a Smart Grid:
▪ In case of low voltage Smart Grid contacts
▪ In case of high voltage Smart Grid contacts. This requires the installation of the
Smart Grid relay kit (EKRELSG).
The 2 incoming Smart Grid contacts can activate the following Smart Grid modes:
