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.
