Auto Gen Start - Where is the Temp Sensor

[JavaJelly]

While testing my Magnum auto gen start found out that the temp setting will engage whether A/C is on or not. I am in cold weather, heating to 72 degrees.

The auto gen start setting was 75 degrees and 11.5 volts. It still came on. When I turned the temp feature off, it doesn't come on. My only conclusion is that the temp sensor is independent of the main thermostat. Anyone know where it would be?

I do know that due to the layout, the bathroom is always very warm in cold weather as it has a dedicated heat vent. The autogen start equipment is mounted in the small cabinet above the stool. Probably the warmest place in the coach. So while it is 72 in the rest of the coach, the generator will still kick on.

If this is the case:

One, turn that feature off while camping in cold weather.

Two, make sure to compensate for that for A/C as the bathroom has no cooling vents. It will always be warmer in hot weather.

Finally, anyone know if the auto gen start can be wired to the coach thermostat?

Scott, I'm not sure how the one you have works, but mine starts the genset when AC demand is called for. In other words really nothing to do with a set temp. as far as a gen start temp., just when ever the thermostat calls for cooling.

It also starts when batteries need to be charged and won't start if the batteries loose their charge.

I did know about the batteries. When tested, I had the auto gen start set at 11.5 volts. The batteries were fully charged.

What I really need to find out is where the thermostat is located for the auto gen start so I can manage it properly. I'll bet it is in w/the control unit.

Scott have you gone to "Find" and typed in "auto Gen start" there is quite a few posts on the subject that may answer your question.

From Manual addendum -

AGS: 04 Start Temp F - This setting allows you to enable and set a high
temperature value that will cause the generator to automatically start. When
the temperature around the AGS temperature sensor increases to the temperature
setting, the generator will be automatically started and run based
on the AGS: 03 Run Time Hour setting. The AGS will attempt to start the
generator immediately once the temperature rises to this setting. The temperature
range selections are 65F to 85F. If this feature is not needed, leave
it at Start Temp = Off.
Factory Default Setting: StartTemp = Off
Why would I need temperature start, give me an example? For RV users, you
could turn the air conditioner on (which is only powered when the generator
comes on) and leave the coach. The generator would come on when the temperature
rises to your temperature setting, thereby turning on the air conditioner.
This allows you to leave pets and precious items in your coach while dry camping
in hot weather knowing your coach will stay cool and comfortable - plus, while
the generator is on, your house batteries are being charged.

This featue is not only for dry camping. Imagine your pet in your coach in a powered park. The power goes down shortly after you leave the park, with pet in coach. The power stays down for three hours with outside temps of 85 degrees.
Bottom line, enable your auto start before leaving the coach if you have pets or anybody not capable of operating this type of equipment should it be needed.

Good posts ecker and Peter...

I definitely know the advantages of the auto gen start. We have a pet and occasionally leave the RV parked for several in warm weather.

Also, we have to dry camp in cold weather a few times a year. So it makes sure the batteries stay up to heat the coach.

It seems the location of the actual temp sensor for the unit is a mystery.

My guess is that having an auto gen start in a DSDP is not too common. I don't have a control panel like in the Essex or LADB. I'll bet that one advantage to those panels is that they can connect the Auto Gen Start to the actual coach thermostat, probably in all zones too.

I'm going to contact Newmar and/or Magnum as I can't find the answer in the manual.

This is Xantrex stuff so probably not helpful but FWIW for others possibly. There are two different gen-starts when for my 06 DSDP. One is limited to sensing the battery voltage and battery temperature and the other works with the heat pumps. The 06 DSDP I have had three different options if one had the proper inverter i.e. 1) no gen-start-contol panel RC7, 2)the charge battery only version-control panel RC7GS and 3) AGS for the heat pumps. To get the later one has to havea DuroTherm AGS harness kit that goes to the heat pumps. The problem I have is that the rig came with RV2000 inverters and the AGS requires RS 2000 inverters.

Scott, we were told that the autogenset works off of the (middle, second, number 2) A/C unit temp sensor. For us, it is under the cabinet in the bathroom. 2007 MADP 4523

I called Magnum today and have an answer for the Magnum Auto Gen Starts anyway.

The thermostat sensor is under the white cover on the remote switch. Which in my case is on the wall next to the refrigerator under the light switches. It's right in the center of the coach which is a good spot obviously.
