In room 4, hotel presence detection is selected via parameter P77, and the
multifunctional input X1/X2(set parameter P38 or P40 to 10) is connected to a card
reader in a hotel application.
∂ At 6:00 when the room is vacant, i.e. no key card inserted in the card reader,
the thermostat’s operating mode is set to Economy. (1)
