1) DTS wiring shows on link below:http://waterheatertimer.org/pdf/1TORK.DTS400A.DZS400A.WIRING.pdf
Timer appears on page below:
2) Tork DTS400B is 4 channel timer, so you can control 4 different Loads with different programming for each Load.
3) I am not 100% certain what you are asking.
Timer can be wired for 120V operation.
Clock motor has separate wiring from Load wiring.
4) Clock motor is shown in wiring diagram as 'Timer supply'
Timer supply is on lower row of terminals.
120 Volt Hot connects to screw terminal identified as 120
120V Neutral connects to screw terminal identified as N
Clock motor wiring does not pass to the Load or channel terminals.
5) Load terminals are not fed by 120V connection to Timer supply.
Each load is wired separately.
For example lets say Load 1 is channel 1 or CH1.
Hot to CH1 connects to terminal C.
Neutral to CH1 connects to terminal NO, or to NC terminal.
6) Terminal NO normally open turns ON when timer turns ON
Terminals NC is normally closed is ON full time, except when timer tuns ON. So NC turns OFF when timer turns ON.
