Have a three device box in the powder room. One for light, one for outlet and one for overhead exhaust fan. Removed the fan device and found two wires; one from hot (black) gang and one to fan. Connected black wire to the hot (black) gang, green wire to ground gang, white wire to neutral (white) gang and red wire to wire that goes to the fan. The green light on the bottom of the timer stays on and the fan stays on. Timer function does not seem to work. No way I can turn fan off unless I disconnect red wire to the fan. Any ideas?
