I have installed my LTB60 in a 4 gang box, with the black wire to the line, red to the load, white to neutral and green to ground but when I turn my circuit on my timer does not function. My 3 other lights in the box work, but the timer will not turn on the fan with any of the buttons. I reinstalled the previous standard switch to the fan and it works fine, so I am not sure what I am doing wrong. There are 6 white neutral wires in the box, and I have added the timer's white wire to the bundle and secured it with a wire nut. Any help would be appreciated.
