INFORMATION
ALWAYS configure the safety thermostat after it is
installed. Without configuration, the unit will ignore the
safety thermostat contact.
6.3.13 To connect a Smart Grid
This topic describes 2 possible ways to connect the indoor 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:
