![]() There is also another cool feature that we do not have on the Landmark. If you have multiple A/Cs running it will also phase the A/Cs in making sure there is a two minute delay between powering each A/C. At that time the relay from the EMS powers the compressor. Seems the EMS always makes sure the A/Cs do not surge the system so the process is thermostat tells A/C to turn on so the fan comes on but the EMS stops the compressor from turning on for two minutes. The interesting thing is that the EMS has this two minute delay even when it has NOT shedded the A/C. There is a little hour glass that shows up when the A/C panels tells the compressor to run but the EMS stops if from running for two minutes. There does seem to be a shedding feedback to the thermostat so that it does not get an error when it tries to power the compressor and the EMS stops it from happening. Looks like the EMS only controls the compressor and does not control the thermostat or fan. Any advise would be highly appreciated.ĭan - great minds think alike. Also before we go after the 30 amp wiring the EMS system (and my multi-meter) says everything is fine and not sure how that would affect a 12 volt circuit. Strange that in only started happening when I am on 30 amps and not 50 amps. Does anyone have an idea what could be blowing that fuse. There is no wiring diagram to show me what actually is on that circuit so it is now a mystery. Seems to be running to Domestic AC panels and the Fantastic Fan and none are running anything but are on. The panels says this fuse is "Back Wall / LP". It has now done this fuse blowing three days in a row. When I replace the fuse the two AC panels come back to life and the fantastic fan starts working again. I check the 12 volt fuse box and the red light is on for position 14. Also there is no power to the Fantastic Fan in the bathroom. The middle AC panel is fine and the is the one AC I am running. When I check the unit when I get home from work the bedroom and back AC panels are dead. Now I am at home and I am running on 30 amps (put a 30 amp RV outlet on the side of the house) I am running just one AC to keep the RV from getting to hot inside. Even when running three ACs (in Orlando) the unit just ran fine. We just came back from a two week vacation in the Ashland and besides the battery charger breaker having to be reset we had no issues.
