Abstract

Electronic device operable by an user for regulating and controlling ambient parameters, such as ambient temperature, comprising a processing unit, a display device for displaying selectable control functions and setting parameters related to a set of desired ambient conditions and a selection/control unit for selecting by the user at least one control function or setting parameter from among a set of displayed control functions or setting parameters. The device comprises an interactive display of a dot matrix type able to display to a user variable indications comprising at least the specific control function associated with each of said selection/control unit according to the specific selection made by the user.

Claims

1. Electronic device operable by an user for regulating and controlling ambient parameters such as ambient temperature, comprising a processing unit, a display device (12) for displaying selectable control functions and setting parameters related to a set of desired ambient conditions and selection/control means for selecting by the user at least one control function or setting parameter from a set of displayed control functions or setting parameters,

characterized in that

the device comprises interactive display of a dot matrix type able to display to a user variable indications comprising at least the specific control function associated to each of said selection/control means according to the specific selection made by the user.

2. Electronic device as in claim 1, characterised in that said selection/control means comprises a predetermined number of means operable selectively for confirming a selection, returning to a previous step and selecting control functions or setting parameters from a selectable set of control functions and setting parameters.

3. Electronic device as in claim 2, characterised in that said selection/control means comprises a pair of buttons operable to confirm a selection and to return to a previous step and a knob to select a control function or a setting parameter from a selectable set of control functions and setting parameters.

4. Electronic device as in claim 2, characterised in that said selection/control means comprises a first pair of buttons operable to confirm a selection and to return to a previous step and a second pair of buttons to select a control function or a setting parameter from a selectable list of control functions and setting parameters.

5. Electronic device as in claim 1, characterised in that said display device comprises a dot matrix liquid crystal display.

6. Electronic device as in claim 1, characterised in that said display device comprises a dot matrix display of a LED type.

7. Electronic device as in claim 1, characterised in that said display device includes means for displaying alphanumeric characters, graphs, icons or numers of predetermined size.

8. Electronic device as in claim 1, characterised in that said display device includes a plurality of display zones configured to display predetermined control functions or setting parameters selectable by the user.

9. Electronic device as in claim 8, characterised in that one of said zones is configured to display time and date.

10. Electronic device as in claim 8, characterised in that one of said zones is configured to display ambient temperature.

11. Electronic device as in claim 8, characterised in that one of said zones is configured to display a graphical representation of a direction corresponding to a relative position along a set of control functions or setting parameters selectable by the user from a predetermined point of reference on said display device.

12. Electronic device as in claim 11, characterised in that said direction correspond to up or down.

13. Electronic device as in claim 11, characterised in that said graphical representation indicates the end or the beginning of said set.

14. Electronic device as in claim 8, characterised in that one of said zones is configured to display an indication that a heating or cooling unit is activated.

15. Electronic device as in claim 1, characterised in that it comprises a sensor for detecting an ambient condition.

16. Electronic device as in claim 1, characterised in that it comprises a memory for storing programs of ambient conditioning.

17. Electronic device as in claim 1, characterised in that it comprises an output for controlling heating and cooling units.

18. Electronic device as in claim 1, characterised in that it comprises a clock for indicating at least time and date on said display device.

19. Electronic device as in claim 1, characterised in that one of said setting parameter selectable by the user is the language of the displayed information shown by said display device.

20. Electronic device as in claim 1, characterised in that one of said setting parameters selectable by the user is date and time.

21. Electronic device as in claim 1, characterised in that one of said control functions selectable by the user is manual control of heating or cooling by setting a definite temperature.

22. Electronic device as in claim 21, characterised in that the manual control of heating or cooling is selectable without time limits.

23. Electronic device as in claim 21, characterised in that manual control of heating or cooling is selectable with time limits.

24. Electronic device as in claim 23, characterised in that manual control of heating or cooling is selectable with time limits for the period of one day.

25. Electronic device as in claim 23, characterised in that manual control of heating or cooling is selectable with time limits for the period of one day repeating over a period of one week.

26. Electronic device as in claim 23, characterised in that manual control of heating or cooling is selectable with a plurality of time limits varying over the period of one week.

27. Electronic device as in claim 1, characterised in that one of said setting parameters includes a set of different display formats to be selected by the user to determine the appearance of the displayed information.

28. Electronic device as in claim 1, characterised in that one of said setting parameters includes a set of pre-defined programs stored in the memory and selectable by the user.

29. Method for regulating and controlling ambient parameters such as ambient temperature, comprising:

displaying on a display device of a dot matrix type a plurality of selectable control functions and setting parameters related to a set of desired ambient conditions;

receiving by a user, through a selection/control unit, a selection related to a set of desired ambient conditions by selecting at least one control function or setting a parameter from a set of displayed control functions or setting parameters;

modifying the displayed control functions or setting parameters according to the selection made by the user;

inputting the modified control functions or setting parameters to a processor unit for controlling a heating or cooling mechanism to achieve the ambient temperature according the selection made by the user

wherein

for each selection made by the user acting on the selection/control unit, the display device of a dot matrix type displays to a user variable indications comprising at least the specific control function associated to each of said selection/control unit.
