4.6.2 Presence detector
The operating mode can be changed to Comfort or Economy mode based on room
occupancy (room occupied or unoccupied, via presence detector or keycard).
The presence detector input switches the operating mode to Comfort when the
room is occupied and switches back to the previous operating mode when the
room is unoccupied.
Presence detection is also possible via bus. In this case, do not assign the function
to any local input X1, X2 or U1.

Comfort mode
When the presence detector is activated or deactivated, the operating mode remains
in Comfort.
Economy mode
● When the presence detector is activated, the operating mode changes to
Comfort.
● When the presence detector is deactivated, the operating mode changes to
Economy (Auto).
Protection mode Presence detection has no influence on the operating mode.
Not available ● When the presence detector is activated, the operating mode changes to
Comfort.
● When the presence detector is deactivated, the operating mode changes to
previous operating mode.
If a room is unoccupied, the operating mode changes to Economy. This overrides
the operating mode on the thermostat. The buttons are locked and symbol is
displayed. An occupied room sets the thermostat back to the previous operating
mode. Use a card reader and not a motion detector combined with hotel presence
function for hotel applications, as the buttons are locked in case of unoccupancy.
Hotel presence detection is also possible via bus. In this case, do not assign the
function to local input X1, X2 or U1.
