Abstract

A fan controller that is capable of switching power to a fan between an “on” state and an “off” state in accordance with one or more programmable schedule. In some cases, fan controller may be programmed to display one or more screens for setting one or more parameters of the fan controller by interacting with a first button and/or a second button. In some cases, when the controller is in an operating mode, depressing a first button, second button, and/or a third button may temporarily override the programmable schedule and, in some cases, override the programmable schedule for a programmable period of time.

Claims

1. A wall mountable electric timer for switching power to a fan between an “

on”

state and an “

off”

state, the wall mountable electric timer comprising;

a housing having a front, a back, and side walls extending between the front and the back, the housing configured to be mountable to a wall with the back situated toward the wall and the front facing away from the wall;

at least one memory for storing a programmable schedule and one or more parameters;

a controller coupled to the at least one memory for controlling the switching of power to the fan between an “

on”

state and an “

off”

state in accordance with the programmable schedule;

a user interface situated on the front of the housing and coupled to the controller, the user interface including a display, a first button and a second button; and

the controller is programmed such that a user can program the programmable schedule and the one or more parameters by interacting with the first button and the second button, the controller is programmed to display one or more screens for setting the one or more parameters by interacting with the first button and/or second button when the controller is initially powered up.

2. The wall mountable electric timer of claim 1, wherein the controller displays a home screen of the electric timer if the controller does not detect the depression of the first button or the second button for a period of time after the one or more screens for setting the one or more parameters are initially displayed.

3. The wall mountable electric timer of claim 2, wherein the period of time is at least 60 seconds.

4. The wall mountable electric timer of claim 1, wherein, if the one or more parameters are not set, the controller is programmed to display the one or more screens for setting the one or more parameters when the controller is subsequently powered up and, if the one or more parameters are set, the controller is programmed to not display the one or more screens for setting the one or more parameters when the controller is subsequently powered up.

5. The wall mountable electric timer of claim 1, wherein the one or more parameters include a floor space parameter, a number of bedrooms parameter, and a fan capacity parameter.

6. The wall mountable electric timer of claim 1, wherein the controller is programmed to display time and/or date information on the display of the user interface.

7. The wall mountable electric timer of claim 1, wherein the controller has an operating mode and a setup mode.

8. The wall mountable electric timer of claim 7, wherein in the operating mode, depressing the first button causes the controller to switch power to the fan between the “

on”

state and the “

off”

state.

9. The wall mountable electric timer of claim 8, wherein in the operating mode, the current time and an icon corresponding to the operating mode are displayed on the display.

10. The wall mountable electric timer of claim 7, wherein in the operating mode, depressing the first button for an extended period of time causes the controller to enter the setup mode.

11. The wall mountable electric timer of claim 10, wherein the one or more screens for setting the one or more parameters are displayed after first depressing the first button and second button when in the setup mode.

12. The wall mountable electric timer of claim 1, wherein the one or more screens include a screen that indicates if the wall mountable electric timer meets the ASHRAE 62.2 standard.

13. The wall mountable electric timer of claim 1, wherein the wall mountable electric timer switches power to a light between an “

on”

state and an “

off”

state.

14. A fan controller for switching power to a fan between an “

on”

state and an “

off”

state, the fan controller comprising;

a housing having a front, a back and side walls extending between the front and the back, the housing configured to be mountable to a wall with the back situated toward the wall and the front facing away from the wall;

a controller for controlling the switching of power to the fan between an “

on”

state and an “

off”

state in accordance with a programmable schedule;

a user interface situated on the front of the housing and coupled to the controller, the user interface including a display, a first button, a second button, and a third button; and

the controller having an operating mode and a setup mode, wherein in the operating mode, depressing the first button causes the controller to switch power to the fan between the “

on”

state and the “

off”

state, and depressing the second button initiates a countdown mode that causes the controller to switches power to the fan to the “

on”

state for a programmable period of time and then switching the fan to the “

off”

state.

15. The fan controller of claim 14, wherein depressing the third button initiates a countdown mode that causes the controller to switches power to the fan to the “

on”

state for a programmable period of time.

16. The fan controller of claim 14, wherein once the countdown mode is initiated, the second button and/or the third button can be used to adjust the programmable period of time of the countdown mode.

17. The fan controller of claim 16, wherein once the countdown mode is initiated, depressing the first button accepts the programmable period of time and activates the countdown mode.

18. The fan controller of claim 17, wherein once the countdown mode is activated, depressing the first button cancels the countdown mode.

19. The fan controller of claim 14, wherein depressing the first button causes the controller to switch power to the fan between the “

on”

state and “

off”

state, wherein the fan remains in the “

on”

state or the “

off”

state until a next scheduled switch between the “

on”

state and “

off”

state according to the programmable schedule.

20. A bath fan controller for switching power to a bath fan between an “

on”

state and an “

off”

state, the bath fan controller comprising;

a housing having a front, a back, and side walls extending between the front and the back, the housing configured to be mountable to a wall with the back situated toward the wall and the front facing away from the wall;

at least one memory for storing two or more programmable schedules and one or more parameters;

a controller coupled to the at least one memory for controlling the switching of power to the fan between an “

on”

state and an “

off”

state in accordance with one of the two or more programmable schedules, a first programmable schedule including a cycled “

on”

state and “

off”

state, a second programmable schedule including a daily switch “

on”

time and a daily switch “

off”

time;

a user interface situated on the front of the housing and coupled to the controller, the user interface including a display, a first button, a second button, and a third button; and

the controller is programmed such that a user can set and/or modify one or more of the programmable schedules and the one or more parameters by interacting with the first button, the second button, and/or the third button.

21. The bath fan controller of claim 20, wherein the two or more programmable schedules includes a third programmable schedule, the third programmable schedule cycling the fan between the “

on”

state and the “

off”

state, the time the fan is in the “

on”

state and/or in the “

off”

state depending on a number of bedrooms parameter, a floor size parameter, and a fan flow capacity parameter.
