Cannon,
I just installed mine last week-end. I set the delay to 136 seconds because when I contacted Jayco they informed me that the A/C unit doesn't have a compressor delay. The only delay is at the T-Stat. Because of this, Jayco recommended the 136 second delay at the EMS to provide full protection of the A/C units.
I installed mine in the basement behind the wall. I needed ~8ft of 6/3 wire to run from the EMS to the power center. I did not cut the original 6/3 wire, this way, if I change campers I can remove the EMS and restore the original wiring.
Also, I switched the red & black wires at the 50A breakers so the Black wire connected to the 50A Leg 1 breaker and the Red wire connected to the 50A Leg 2 breakers. This way if you follow the EMS instructions for wiring the unit (i.e., Black wire to L1 & T1 and Red wire to L3 & T3), the Line 1 and Line 2 info presented at the EMS display with be consistent with Leg 1 and Leg 2 of the trailer.
I chose this location for the EMS because Progressive Industries indicated that the EMS does generate heat and to locate it in a ventilated area.
I also bought a
remote display and switch so I could have a switch inside and by the LCI leveling system control panel.
I had to purchase a 25' data cable to run from the switch to the inside display. The data cable is a RJ11 4 Conductor Straight Wired Modular Telephone Cable - 25 FT that I got from the
Computer Cable Store.
I've attached a couple of pictures.
FYI - the EMS' relay contactors make a loud click when engaging.
More info then you asked for but hope some of this is helpful.
Good luck.
