presence detector sensor: Only one input source must be used, either local input
X1/X2 or KNX bus.
This function can be selected via parameter P77=2.
The presence detector status can be set via card reader or presence detector
connected to the local multifunctional input (set P38 or P40 to 10) or via KNX (S-
Mode).
Response when the room is unoccupied, i.e. when the key card is removed from
the card reader or when the presence detector no longer detects movement.
∂ The operating mode of the thermostat switches to Economy.
∂ Changing the operating mode via local HMI is not possible (locked HMI) to
ensure Economy is active when rooms are unoccupied.
The operating mode can still be changed via bus, e.g. the hotel front desk switches
the operating mode to Protection upon check-out or extended vacancy.
Response when the room is occupied, i.e. when the key card is inserted or when
the presence detector detects movement.
∂ The thermostat returns to the last operating mode set for occupancy (either
Protection or Comfort)
If the operating mode is changed via bus during vacancy, the change is not based
on detection, e.g. front desk can set the operating mode to Comfort after guests
check in.
