CLAIMS

1 . A method for adjusting a water recycling device (100) to a user preference profile (222), wherein said water recycling device (100) comprises:

5 an outlet (104) configured to output treated water;

a drain (106) for collecting used water output from said outlet (104);

a recirculation loop (102) in liquid communication with said drain (106) and said outlet (104), said recirculation loop (102) comprising a water treatment arrangement (1 12) for treating said used water;

0 an external water path (108) in liquid communication with said

recirculation loop (102), said external water path (108) being connected to an external water outlet;

a circulation pump (1 10) for providing a flow in said water recycling device

(100); and

5 a sensor arrangement configured to measure a water quality parameter of water in said water recycling device (100);

said method comprising the steps of:

receiving data indicating an upcoming use of said water recycling device (100) by a user;

o processing said data in order to determine a probability of use of said water recycling device by said user within a time period; and

if said probability of use exceeds a threshold, adjusting a number of operating parameters of said water recycling device according to a user preference profile (222) associated with said user.

5 2. The method according to claim 1 , wherein said number of operating

parameters comprises at least one operating parameter selected from the group consisting of an output water temperature, an output flow rate, and an output duration.

3. The method according to claim 1 or 2, wherein said number of operating 0 parameters are adjusted such that the same vary over time during a period of use of said water recycling device.

4. The method according to any one of the preceding claims, wherein said data comprises internal data 224 generated by said water recycling device.

5. The method according to any one of the preceding claims, wherein said data comprises external data 226 generated by an external device communicatively connected to said water recycling device.

6. The method according to any one of the preceding claims, wherein said data comprises historical data related to said number of operating parameters of said water recycling device.

7. The method according to any one of the preceding claims, wherein said data is compared to said user preference profile in order to determine said probability of use of said water recycling device.

8. A method for generating a user preference profile (222) for a water recycling device comprising (100):

an outlet (104) configured to output treated water;

a drain (106) for collecting used water output from said outlet (104);

a recirculation loop (102) in liquid communication with said drain (106) and said outlet (104), said recirculation loop (102) comprising a water treatment arrangement (1 12) for treating said used water;

an external water path (108) in liquid communication with said recirculation loop (102), said external water path (108) being connected to an external water outlet;

a circulation pump (1 10) for providing a flow in said water recycling device

(100); and

a sensor arrangement configured to measure a water quality parameter of water in said water recycling device (100);

said method comprising the steps of:

receiving data associated with a number of uses of said water recycling device (100);

identifying a user group of said water recycling device (100) based on said data, wherein said user group comprises a number of users;

determining a number of operating parameters of said water recycling device (100) associated with at least one use of said water recycling device by at least one of said number of users; and

generating a user preference profile (222) comprising at least part of said number of operating parameters for said at least one of said number of users.

9. The method according to claim 8, further comprising the step of updating said user preference profile

identifying said user preference profile;

receiving user preference feedback (552) indicative of a user preference 5 of said user;

updating said user preference profile according to said user preference feedback (552).

10. The method according to claim 8 or 9, wherein said user preference feedback is received from said user via an interface communicating with said water o recycling device.

1 1 . The method according to any one of claims 8 to 10, wherein said user preference feedback is based on observed behavior of said at least one of said number of users.

12. A system comprising

5 a water recycling device (10)0 comprising

an outlet (104) configured to output treated water;

a drain (106) for collecting used water output from said outlet (104); a recirculation loop (102) in liquid communication with said drain (106) and said outlet (104), said recirculation loop (102) comprising a water treatment o arrangement (1 12) for treating said used water;

an external water path (108) in liquid communication with said recirculation loop (102), said external water path (108) being connected to an external water outlet;

a circulation pump (1 10) for providing a flow in said water recycling 5 device (100); and

a sensor arrangement configured to measure a water quality parameter of water in said water recycling device (100); and

a prediction engine (225) configured to

receive data indicating an upcoming use of said water recycling device 0 (100) by a user;

process said data in order to determine a probability of use of said water recycling device (100) by said user; and

adjust a number of operating parameters of said water recycling device (100) according to a user preference profile (222) associated with said user if 5 said probability of use exceeds a pre-determined threshold.
