Abstract
The present invention relates to a building control system, and more particular to a method and a device for set point adjustment in a building control system. The device (308) for set point adjustment comprises an active sensor configured to sense the distance to an object (310), for example at a first distance (304) and at a second distance (312). In response to sensing the movement of the object (310), the device (308) adjusts the set point from a first set point to a second set point. The second set point depends on the first set point and an offset between the first distance (304) and the second distance (312).
Claims17
A method for set point adjustment in a building control system, comprising the steps of:
- sensing (S602) an object (310) at a first distance (304) from an active sensor (202), whereby the set point adjustment is initiated;
- sensing (S604) a movement of the object (310) from the first distance (304) to a second distance (312, 412) from the active sensor (202);
- and
- adjusting (S606) the set point from a first set point to a second set point in response to sensing the movement of the object (310), wherein the second set point depends on the first set point and an offset between the first distance (304) and the second distance (312, 412).
A device (100, 308, 408, 508) for set point adjustment in a building control system, comprising:
- an active sensor (202) configured to:
- sense an object at a first distance from the active sensor, whereby the set point adjustment is initiated;
- sense a movement of the object from the first distance to a second distance from the active sensor;
- and
- a processing unit (204) connected to the active sensor (202) and configured to:
- adjust the set point from a first set point to a second set point in response to the active sensor (202) sensing a movement of the object, wherein the second set point depends on the first set point and an offset between the first distance and the second distance.
