Intellitec EMS Problem
I have an Intellitec Model 800 EMS in my 50 amp coach. Lately it has been doing strange things. When plugged into 120v power the display indicates 50 amp service. When running on the genset, the di...

If you are a self designated expert on this model 800, why do you state that there are only 4 relays. I am an engineer and have designed electrical circuits and controls.
Before my test, all equipment was operating properly. However, the remote display was alternating between 50 and 30 amp with the ammeter showing 0 while at the 30 display.
On genset, the display alternates between 30 and genset with 0 amps. I have confirmed proper voltage at the breakers and the proper 12v run signal from the genset.
The system is using two high voltage relays for the washer/dryer and the water heater. The breakers to the airs are wired direct.
When the ACs startup you hear the fan start with the compressor starting sound 1 to 2 secs later and blowing cold air.
Since I have accounted for all Four of the hi load relays, that only leaves the two low voltage relays fot the two airs. It appears they are setup to interrupt the airs if necessary.
I believe the reason for the shutdown of one of the airs in my original post was due to the outside temp being 65 and the unit icing up. Today it is 78 and both run fine but the remote display is wonky.
Both airs still continue to run when the fuse is pulled. I also tested the relays and all are operating normally.
Over to you.
P.S. My system is set up to shed BOTH ACs if necessary.
