The timer lets you adjust the preset astronomic time for your area.
This is because actual local times vary.
If the preset time for dusk is 8:00pm and you add 12 minutes, then the timer will turn off-or-on at 8:12.
And then you can change the preset time for dawn by adding or subtracting.

If this is not what exactly you are asking, then set your timer and see what happens, and then add a comment with your findings.

You parallel the contacts then either one or both will turn it on. Both have to be off for the fan to stop.

A Leviton DHC receiver device can look like any other switch or receptacle so if you didn't install it or not provided a map then you'll need to locate it.

Likely the wall switch that originally controlled the light was replaced with DHC device and paired with the 16400 at another location. If you can't identify it, then removing face plates and devices may be the only practical method to locate it.

If your not comfortable with removing devices safely, hire an electrician.

The Leviton LTB30 20 amp timer has a known design flaw. It has a 1 microfarad electrolytic capacitor installed against a screaming hot resistor. Cooks and dries out the cap even when not in use. 50% failure rate in my initial install of 4 units. Pull it apart and replace the electrolytic with a ceramic cap and it will be fine. I have two of many that have already failed. Poor design of voltage regulation and poor layout of cheap components that self destruct. Design is not half baked, it is fully baked, lol. Can be fixed though, so not all bad...

It's two single pole switches with a removable jumper on one side. With jumper intact, you connect the hot feed to a either screw of the jumper which I belive are brass colored screws.

Then the two induvidual switch poles are the silver screws. Connect fan motor to one and fan light to the other.

If that doesnt work for you, take a picture of the switch and connections and another of wires in fan box and post here.

If I understand you correctly, your hot lead should attach to 1 switch and a common wire goes from that switch to the other switch. Here's a link to a good explanation of 2 way switch wiring. Essentially you run power to one switch, and that same switch sends power via 1 of 2 other wires to the second switch. The light (or other device) is then connected to the second switch. Hopefully the diagrams in the following link will help you. In any case you need 3 wires at each switch. Good luck!

Crack it open and see (dill off any rivet heads).

replace it, they are not expensive. They are a disposable item.

The following link has manuals for Leviton timers: http://waterheatertimer.org/Leviton-timers.html

what do you know as "regular " bulbs are they low energy or incandescent

adjust the sensitivity switch

Replace it. They fail and and that is not uncommon. good luck

red never connects to black as that is power to neutral if wired correctly get in a qualified electrician to check the wiring and help you install the unit

ISP = Internet Service Provider, so that is the information of the provider it sends to get you connected to the net, it talks to the MAC adres on the Network card, if they speak the same language you have internet. :-)

most if not all these padlocks when first manufactured the manufactures has to set it with some digits if it four digits lock , manufacture use eg., 0000 or 1234 and if it six digits it uses 000000 or 123456 and so on the idea is that when the lock is first bought it comes with these digits then by following their instruction you can change the code you wish to have
