How To Verify your ITR OASIS Two Electric Burners are working

[Neal]

I’m stumped.
Today I opened the main panel and checked all leads with wolf meter. Both L1 and L2 are getting 120V.
But on the Power Control Monitor, I’m getting L2 7V like the picture I posed yesterday.
Turned off the shore power and fired up the generator. No change. L1 shows 7V. Any ideas?

@Buly I think this warrants a new thread on the topic of your problem. I suggest using the salesman switch to kill 12V power to reset your EMS but again maybe a new thread to focus on this problem.

I believe when you are on 30A you are only using one line of L1 and L2. 50A is 2 x 30A lines, no? When I was on the phone with ITR they told me that it had to be 50 and I assume because of this. I believe too that when you're on 30A you can ONLY use AC I and NOT AC I/II.

Hmmmm. I have a 30A service here at the sticks-and-bricks that I have the MADP plugged into currently and I am able to use both AC1 and AC2 on it. At least, both indicator lights are on and it keeps the coach as warm as I think it should with both elements on. We are plugged in using a 50A-to-30A adapter that splits the power to each leg (L1 & L2). I wonder if that makes a difference?

In my coach for example you can put the switch to AC I/II but only one leg exists on 30A service. @Chuggs maybe you can chime in? The green light will come on but it doesn't mean you have both heating elements in use. I really don't know how the 30A works between L1 and L2. Maybe something manages which path the trons take. Thinking about how Air Conditioners on the roof handle this, I don't think everything is on just one line so I'm stumped.

Just checked mine AC1 increase 12a L2, AC1/2 increase 10A L1, these were my results on 30A service. I had an increase of amperage L2 when selecting AC1 and increase of amperage on L1 when selecting AC1/2 which I am assuming is really just turning on the second heating element.

My understanding of Oasis AC heating elements is 1 element provides approximately 5000 BTUs and other element 10,000 BTUs for 15000 BTUs with both active. I would of thought that amperage draw would be slightly different between the 2 elements but saw 10a increase for each.

Just trying to understand the system and now starting to question what I thought I knew?‍

My understanding heating elements are 5000 BTU each (net 10K BTU when using AC I/II). The burner is 50K BTU.

Yes went back to manual and both elements are 1500W, 120 VAC so they are the same. Makes sense they both show same amperage draw. Thanks

I think they are rated in watts, not BTU, but I could be mistaken. The 12A increase when you turn one on confirms the 1,500W rating (120V x 12A = 1440 W...close enough to the 1500W rating).

They should both work...EXCEPT...the mgmt system may load shed one.

Background... Yes, when connected to 50A shore power...the coach has two legs. Each distributed to our breaker panel by means of the 50A breakers.

When connected to 30A...the dog one adapter tied a single leg of 120v line power to both of those 50A. Of course, we could easily overload the 30A source and trip the 30A breaker in the pedastle, were it not for the management system in our coaches designed to shed loads as needed.

if you turn your a/c(heat pumps)..you should be able to see the amperage draw from both electric elements. If you don’t...there should be a corresponding amp reading next to the element on the list of shed items. The reading is the amount of amp “overhead” required for the system to automatically reinstate that item.

Guess the myth of only using AC I is incorrect. You can use AC I/II and utilize both burners then but EMS may load shed. Not sure where these burners are in priority in EMS shedding. Good info share ALL.

Check to make sure the engine heater breaker is on. Had a similar issue and it turned out the power management system was getting one lead data from the output side of the engine heater breaker.

The order is programmed by Newmar. As you page thru the displays...the items and the order are listed On the Load Status pages. Beginning with the Block Heater and ending with the Front A/C unit.

Block Heater
Water Heat 2
Water Heat 1
A/C Middle
A/C Rear
A/C Front

That is the order programmed on my Coaches system.

You are right, I sent an email to Precision Circuits Sunday around 6PM. George called me around 8PM the same day, and told me to check for any breakers turned OFF. Sure enough, my "Block Heater" breaker was OFF (who needs it in FL?). After turning it ON, L2 worked. That's the good news.
The bad news is AC2 on the Oasis does not work. Got to open it AGAIN ?

Interesting, I could see me flipping the breaker on engine heat. Sorry you have to open it back up but glad it’s figured out
