Roger, I added a switch months ago after repeatedly being woke up by the compressor coming on.  I put a relay between the fuse and the Essex relay.  I was not aware that it would energize the blow down solenoid.  Do you think this matters?  Will having the solenoid energized make much of a difference in it lifespan after all it is just a electromagnet?  My 2002 is when they started putting in the bigger compressor and the switch and solenoid to send air to the wet tank, but it is controlled by a switch and not by the HWH control board, so it will have no effect on that solenoid. 
No worries David.  It is a 270, so I don't have fancy things that can break like air controlled automatic awnings :) and thank God for that. I spend enough time fixing things.  I understand they never really worked right and were discontinued after a couple years.  Hope yours is still going strong.

Going like a champ still.. really enjoy it but .. electric, pneumatic or manual .. they all work

This is the wiring diagram for coaches with the bigger compressor and the line to the wet tank.  This switch is for opening the solenoid valve to that line and for forcing the compressor to start.

Adding a switch in the 6100 wire will disable the compressor at the pressure switch and this not power the water trap solenoid (close it).  It will also make the wet tank solenoid switch only when you enable the pump switch.

If the water trap solenoid is on all the time it is a constant power drain, the solenoid gets hot and that heat may compromise the plastic bowl.  If that bowl leaks your compressor could run continuously.

Went and changed the wires going to my switched relay to the control wire and spliced the fuse wires back together.  Glad I put the switched relay next to the pressure switch.  Made switching wires over a lot easier.  Thanks for the heads up Roger.  Saved me replacing a solenoid or possibly the compressor.
