Yes...exactly.
While sitting in your RV...try this. It’s a confidence maneuver.
Turn your Dometic thermostat up to 80 degrees...
Make sure the air conditioner finishes it’s current cycle and shuts off...
Arm AGS...with a low voltage, so that voltage isn’t the trigger, and EXT INPUT selected in lieu of a temperature.
Go outside and trip the breaker...
You are now running off battery power...the Inverter should go into inverting...and Lights TVs all working.
Now, lower the thermostat to a couple of degrees below the current inside temperature.
If you get the chance...watch the load Management Panel...
This is what your looking for..
The Dometic thermostat will try to turn on the air conditioner..
The unit will determine there is no Shore or Generator feeding the main distribution bus.
The AGS will see this signal...
The Magnum Network will shed the 6 loads it controls.(if optioned)
The genset will start...
The generator runs unloaded for two minutes...
The load Management Center reinstates the loads
The air conditioner should start and cool the coach...
What happens after this depends on software revisions...
Newer models... Yours will have this.
Air conditioning shuts down when reaching the temp set point on Dometic Control...
Load Management dumps loads...to unload generator and let it cool down for two minutes..
Generator shuts down...
Older models... In case someone with an earlier coach is reading along.
I haven’t watched this, but I believe the generator runs for the generator run time. So, if you set 3 Hours in the generator setup...it runs for three hours. At the end of the timer, it looks to see if the air conditioning is off...and it shuts down. If the air conditioning is still on..it resets the timer for another 3 Hours, or whatever you programmed the run time to be.
Someone with the earlier revision will have to check me on that.
So...the remote temp sensor that can be used with the AGS was deleted in favor of a networking connection to Dometics brain box....down in the basement. The temp sensors that control the AGS are the same little slotted half spheres mounted on the wall that control your air conditioner.
Oh...when your done, done forget to reset the breaker outside...otherwise the generator will fire up again and startle the dogs...
