You can leave them up (at least in command mode) and then dial them up with the remote. 

 

All 4 throttles can be set to whatever max you desire, and they will start at 0 volts until addressed and changed with the remote.  (an improvement on the previous 2 modern ZWs that had the inner 2 channels start wherever you set them and you had to dial them down)

 

I don't remember for sure how it behaves without a base as I don't use it that way.  (but I understand why you would ask if you were feeding a TIU with it that may not have a TMCC or Legacy base installed)

I know you don't have to turn the handles off on the ZW-C.  And nothing in the manual says anything about needing to have the handles off for the ZW-L.

 

I read both manuals a couple of times trying to decide which of the 2 ZWs to get.  In the end I got a ZW-C because I came across one at a killer price with the meters.  Otherwise I'd be all over this ZW-L.

I like the option of using the B and C outputs that will go right to 18 VAC when turn on the ZW-C

The ZWL is really interesting, but do you have to rotate the throttle to run the outputs up to 18 volts, or can you just hit boost and it'll jump right up to 18?

Sorry, I guess I should have added "IMO" to my statement that I thought it was an improvement.  I realize others might like it the way the ZW-C worked.  I generally might have 4 small loops for a Christmas display, so having 2 of them start at full was not a positive feature when I used the ZW-C in this application.  (I would normally have a trolley or handcar loop or 2, so those would be the loops I would use on B&C)

 

I always spin the wheel on the L to get the voltage.  I'll check and see if hitting boost does anything different.

Its hard to beat the reliability of an original ZW.  The new ZW-L does offer some great features over its original counter part...

 

1. 620 watts of power in one unit.

2. Power folding - The system will auto distribute power (up to 180 watts per channel) as needed.  Up to a total 620 watts.  If you reach the limit, the red light will flash but the transformer will continue to supply up to its limit of power.

3. 200 speed steps.  Really fine power control

4. It supplies a chopped sign wave.  This allows pulmor motor engines to run really well and at much slower speeds.  I have seen a difference with some of my older equipment.

5. If a channel gets a short, just the one channel will shut off.  The rest of the transformer stays up and running.  You can then reset the channel via the remote and dial the power back up.  I love this feature.  Additionally, the gauge will turn off to let you know which channel is out.

6. I use one ZW-L for my 12x18 layout.  It powers all my tracks, switches, operating tracks and lighted bumpers.  It runs it all without ever getting warm enough to kick its internal fan on.

7.  I've testing running double headed GG-1s (that's 4 pulmor motors) with a string of lighted passenger cars.  The one channel was pulling 8.5 amps.  The other 3 channels still put out what was needed to run my layout.  With this load the fan kicked in (and its really quiet).

 

8. In command mode - you have to rotate the knob on the remote to dial up the power - for all 4 channels.  I called Lionel and confirmed this is correct.  This is a change from the ZW-C.  The ZW-C would auto turn on channels B & C in command mode.

 

9. You can program the ZW-L as an engine or Train in the remote.  Another neat feature.

I can't say enough good things about this transformer.
