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...

1. As I stated, YOUR system uses Compressor shed and NOT shed of complete 120 power to the AC unit, hence the AC's "run". That is a NICE feature of using the 800 system to utilize Compressor shed and leaving complete power to the AC units. THAT info would have been helpful at the start. But if the 800 has a major malfunction, the Compressors will not come on. You CAN make them come on if the system malfunctions by disconnecting BOTH yellow wires at each AC at the AC control board accessed thru the air filter grill
2. YES, I AM a EXPERT, NOT self professed. I have been working on and FIXING RV's for 35 years now. Despite what some Engineers think, they are NOT experts at ALL things. I AM an expert and know MORE about the 800 system than you will ever know.
2. Lets get back to your original problem, IF all wires are secure and no corrosion, the fact that your system remote was going bonkers, shows the Main control board is malfunctioning.
3. Your system (roof AC) CANNOT ice up despite any temp. They have a freeze Thermister in each Evaporator that prevents that despite ANYTHING that could cause Ice build up. But, as an Engineer, you knew that. Sorry, you did NOT know that. So, you are not as smart as you think:B
4. As I stated, when you have compressor shed the systems ARE designed to shed either or both compressors instead of the 120 power. But if complete power shed they only shed the rear AC unit power.
5. The 800 system has extra design parameters that can include compressor shed. Very few RV makers utilized compressor shed back then.
6. You probably need a new 800 control module. Have you check for 12 volt signal at the Genset wire at the quick connect at the module board J2 pin 2? IF you have 12 volts on that wire and it does NOT state GEN on the remote panel, then the module is defective.
7. Last, curb you sarcasm, I am an expert and trying to help you. YOU posted asking questions because you obviously do NOT know what you are doing. YOU keep changing the parameters and scope of the problem, and I have to catch up. Doug
