Intellitec question

[Dinestro]

Hello and great forum. I recently purchased a southwind storm 34b with duel ac and that intellitec system. The rv was mint except for a few outside scratch ups which my body shop is fixing at the moment. The problem I have is the old owner installed a new ac in the rear with knob controls. In the breaker compartment under the fridge there's a 3 way house rocker switch installed? Well the rear ac will work fine obvious of the intellitec system. When I have the gen set running. Rear ac off and try to fire the front ac no good. On high cool the fan blows but no cooling. It worked a week ago. I have no clue. I want to get rid of the intellitec sys and install a digital thermo for the front ac and furnace. Is this a problem? Obviously I know I can't run both at the same time. But when the kids are with us the front ac should be enough to cool the coach. Any in site would be greatly appreciated. I still have no clue what that damn switch is for under the fridge. It's a 3 way rocker. Buts it's a 110 home light switch installed in z box bolted to floor.

Typically there will be a switch that selects either front or rear ac as the one to be powered from the house 30A supply. Only one ac gets powered from that source.

Also typically in Fleetwood coaches, the generator can power the rear ac directly while the front ac receives power from the main house 30A supply. The 3-way switch needs to be in the "front ac" position to do that. That allows operation of both acs when using the generator.

The Intelletec you have is probably a power load manager integrated with the thermostat. The idea is that it sort of alternates the two acs by sharing one power source. If you are willing to do that manually, you can replace it with a different t-stat, but you have to make sure the power wiring that is now handled through the Intelletec gets routed correctly. It's been ages since I looked at one of those, so have forgotten the details myself. Probably somebody else will join in with some up-to-date advice.

I'll try that Monday at the shop thanks

Not sure what year your coach is but my 99 bounder controls both the rear ac and the front ac. The intellic system monitors the current through the main power and shuts down loads when the current is to high.

The first load to be shut down is the compressors on the ac units.

I am not sure which system you have but if you have what I think your using dometic A/C units. Remove the filter screen from the front unit and look up there should be a control box with wires going in and out on the pass side of the box is a bunch of wires 2 blue , 2 yellow, and red and black. If the yellow wires are hooked up unhook one of them to test the A/C. The Intelitec and other systems use the yellow wires to shut off the compressor by connecting them with a switch. This does not mean you Intelitec is bad but will let you test the A/C without the system shutting down the compressor. The front rear switch controls 120v power to the A/C units so you can select one or the other and must be in front mode when using the generator so you can run both.
