Outside a room there are three light switches. one switch is connected to the only light bulb inside the room. each of these three switched can be either "on" or "off". all start in the "off" position. you are allowed to set each switch the way you want it and then enter the room (note: you can enter the room only once) your task is to then determine which switch controls the bulb. how would you do this?

'define control'
anyway, that all the lights work together makes it simpler
most fanlights, updated by homeowners replace a lamp only unit, with on/off provided at the switch, and cable pulls on the unit to change speed direction of the fan
my favorite is paired dimmer switches, giving control separately of light and fan speed, fan direction still changes on the pull switch, requires 3 wires in the switch box, (power and 2 switched lines), to the lamp connector and fan motor connector, any sparky can pull the extra line with fishtape along the existing cable run. easy peasey.
Really good electricians pull three wire to light circuits, when the house is built or reno-ed. but you know how oftern that is gonna happen, 3 wire costs 3c more per foot, if there is 3 wire in the switch box -your home and hosed
or just for speed/dimmer control a dimmer switch can replace the existing single switch. but you still have to pull the cords to start the fans
its easy, with the caveat that you may kill yourself, or someone else, or burn the house down, if you dont do it right
SOURCE: How do I wire this table lamp?
first check out the sw. use a volt meter measure between all of the lines. i.e black & red, black & green tec.... and tun the switch to each position.
note the output on the meter, when you turn the sw. that will tell you which 2 lines are switched and the which is fixed.
1). connected the hot "line in", to one line from each of the buld.
2). take the left over line from buld #1, connect it to one of the switching line on the sw.
3). take the left over line from buld #2, connect it to the other wsitching line.
4). connect the left over "line-in" to the fixed line on the switch.
SOURCE: Wiring Bathroom light/vent/heater switch with 3 separate controls
Wiring a bathroom combination vent, heater, light 3 way switch means more wires. In brief, you need to run two cables - one a two wire and one a three wire from the switch to the fan.
Incoming power will have white black and ground.
The two wire cable for the switch to the fan will have wht, blk, and ground.
The three wire will have red, blk, wht, and grnd.
The switch will likely have 2 blacks and a red coming from it, with two blacks and a red on one side, and a single black on the other.
The fan should have a red, blue, green, black, and white.
On the fan end: Group all green/copper grounds together and use a wire nut to fasten them together. Tape the nut to the wires.
There will be five white wires coming through. For ease of handling, using wire nuts, connect two on one nut and three on the other.
connect the blue to a blck. Connect one red to one black, and the other red to the other black.
The switch will have one red going into the 3 wire cable, a black going to the 3 wire cable, and a black form incoming power to the side opposite the 3 wires, and a blck going to the two wire cable.
There. Confused?

This is a very strange arrangement, your switch
BTW, my pleasure ... I am a volunteer poster here - not an employee. I'm at home ... watching Dancing with the Stars - I do this for the 'bragging rights'. I'm not perfect but pretty darn good for a High School shuv-out!
You may be able to find a "Off - On (1) - ON (2) - Off" kind of switch ... I'm racking my little brain from when I worked as a (50 year+old) stock boy at the Ace hardware/Auto supply, row 3 - electrical - to see if I remember seeing that switch. I'm pretty sure there is such a thing.
Your arrangement is very strange. Take your switch to the hardware and spend some time exploring. And forget the big box store for now ... look at your little hardware store first. I think they will most likely be able to find you a replacement or the switch I described above.
Thanks for using Fixya.com and I hope I have helped you with your question.

Manual say 'incandescent' light bulbs only.
What can I control with my EJ351C?
The EJ351C timer is to be used with standard base incandescent light bulbs only! It should not be used to control lighting such as:
