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...

To prove my point I just turned both ACs on with 50A shore power. I the pulled the 12V fuse in the control module. BOTH ACs CONTINUED TO OPERATE
If the system was malfunctioning, WHY did BOTH AC's come on BEFORE you pulled the fuse? Power down the system (120 and reconnect 120) and see if the AC's operate. Why am I hard to convince? Because I have worked on SCORES of Intellitec 700 and 800 model shed systems over the years and have NEVER had any power to the Shed appliances when it malfunctions. THAT is a common complaint when the Intellitec does malfunction--- it is HOT outside and they cannot get their rear AC to operate. Are you positive the compressor came ON and it was not just the fans operating. As I stated, the Front AC is not affected by the Intellitec shed system. What Year/Brand/Model RV do you have? Doug
From the Manual. Your AC/W/H are NOT low voltage loads
The remainder of the relays, relays 5 and 6, are intended to switch low voltage loads. Relays 5 and 6 are single-pole, doublethrow
relays with all contacts available.
You have a Thor product and I believe they do indeed utilize COMPRESSOR shed which means the AC fans will run regardless of the Intellitec, but the compressors will not come on if the Intellitec is out of the loop. You may have the shed relays fused closed also. I have never seen it,but if you do indeed have complete power to the Roof AC compressor and fan, that is the only way. The LOW voltage shed relay's are for the tstat compressor control thru the roof AC compressor.
