Abstract

Motorized window treatments may each adjust a position of a covering material to allow light into a space in a building. The control information for controlling the motorized window treatments may be stored and/or accessed to understand how the motorized window treatments are operating. The control information may indicate a control state and/or a position of the covering material when an identified daylight intensity is being received at the space. The control information may inform a user of the operation of the motorized window treatments and allow the user to adjust various control parameters by which the motorized window treatments may be controlled. Recommended adjustments may also be provided to the user based on a user-identified problem with the operation of the motorized window treatments. The recommended adjustments to the control parameters may be accepted by the user and may be stored for being accessed and/or edited.

First claim

What is claimed is:

1. A motorized window treatment positioning controller, comprising:
control circuitry to:
receive one or more input signals;
determine whether the one or more received input signals include a deviation from a defined automated control state;
responsive to the determination that the one or more received input signals include a deviation from a defined automated control state, select one of a plurality of override control states based on the received inputs;
transition from the automated control state to the selected override control state;
determine a position of the window treatment based on the selected override control state and at least one of the one or more received input signals; and
cause an actuator operatively coupled to the window treatment to transition the window treatment to the determined new position.

2. The motorized window treatment positioning controller of claim 1 , wherein to receive the one or more input signals, the control circuitry to:
receive, from an operatively coupled daylight sensor positioned in a space, an input signal that includes information indicative of an illumination level within the space.

3. The motorized window treatment system of claim 2 wherein to select one of the plurality of override control states based on the received inputs, the control circuitry to further:
select, based on the received inputs one of the following override control states: a dark override control state, a bright override control state, or a hold visor override control state.

4. The motorized window treatment system of claim 3 wherein to determine whether the one or more received input signals include the deviation from the defined automated control state, the control circuitry to:
determine whether the illumination level within the space is greater than a bright override threshold; and
transition from the automated control state to the bright override control state responsive to the determination that the illumination level within the space is greater than the bright override threshold.

5. The motorized window treatment system of claim 4 wherein to determine the position of the window treatment based on the bright override control state, the control circuitry to:
determine the position of the window treatment using a weight factor based on the illumination level within the space and the current position of the window treatment.

6. The motorized window treatment system of claim 3 wherein to determine whether the one or more received input signals include the deviation from the defined automated control state, the control circuitry to:
determine whether the illumination level within the space is less than a dark override threshold; and
transition from the automated control state to the dark override control state responsive to the determination that the illumination level within the space is less than the bright override threshold.

7. The motorized window treatment system of claim 6 wherein to determine the position of the window treatment based on the dark override control state, the control circuitry to:
determine the position of the window treatment using a weight factor based on the illumination level within the space and the current position of the window treatment.

8. The motorized window treatment system of claim 3 wherein to determine whether the one or more received input signals include the deviation from the defined automated control state, the control circuitry to:
determine whether a user input includes information indicative of a user identified high illumination level or a user identified low illumination level; and
transition from the automated control state to the hold visor override control state responsive to receipt of one of: the user identified high illumination level or the user identified low illumination level.

9. The motorized window treatment system of claim 8 wherein to determine the position of the window treatment based on the dark override control state, the control circuitry to:
determine the position of the window treatment using the current position of the window treatment and a weight factor based on one of: the user identified high illumination level or the user identified low illumination level.

10. A method to control the position of a motorized window treatment, the method comprising:
receiving, by motorized window treatment control circuitry, one or more input signals;
determining, by the motorized window treatment control circuitry, whether the one or more received input signals include a deviation from a defined automated control state;
responsive to the determination that the one or more received input signals include a deviation from a defined automated control state, selecting, by the motorized window treatment control circuitry, one of a plurality of override control states based on the received inputs;
transitioning, by the motorized window treatment control circuitry, from the automated control state to the selected override control state;
determining, by the motorized window treatment control circuitry, a position of the window treatment based on the selected override control state and at least one of the one or more received input signals; and
causing, by the motorized window treatment control circuitry, an actuator operatively coupled to the window treatment to transition the window treatment to the determined new position.

11. The method of claim 10 , wherein receiving the one or more input signals further comprises:
receiving, by the motorized window treatment control circuitry, an input signal that includes information indicative of an illumination level within a space from an operatively coupled daylight sensor positioned in the space.

12. The method of claim 11 , wherein selecting one of the plurality of override control states based on the received inputs further comprises:
selecting, by the motorized window treatment control circuitry, based on the received inputs one of the following override control states: a dark override control state, a bright override control state, or a hold visor override control state.

13. The method of claim 12 wherein determining whether the one or more received input signals include the deviation from the defined automated control state further comprises:
determining, by the motorized window treatment control circuitry, whether the illumination level within the space is greater than a bright override threshold; and
transitioning, by the motorized window treatment control circuitry, from the automated control state to the bright override control state responsive to the determination that the illumination level within the space is greater than the bright override threshold.

14. The method of claim 13 wherein determining the position of the window treatment based on the bright override control state further comprises:
determining, by the motorized window treatment control circuitry, the position of the window treatment using a weight factor based on the illumination level within the space and the current position of the window treatment.

15. The method of claim 12 wherein determining whether the one or more received input signals include the deviation from the defined automated control state further comprises:
determining, by the motorized window treatment control circuitry, whether the illumination level within the space is less than a dark override threshold; and
transitioning, by the motorized window treatment control circuitry, from the automated control state to the dark override control state responsive to the determination that the illuminat
