In QT's # 3 there are detailed instructions by DS Don and PDR John on the Oasis system its use and maintenance, I would read the items through so you have some knowledge of how system works and will have a better understanding for questions you may want further answers.
DS Don's link above is one of others to help you understand the systems in your coach.
All the links below in my signature will relate to your Newmar.

two options

You have two options for heat: The HP which is heat pump (the A/C compressors on the roof used as heat pumps) and FURN (or AQUA) which uses the heat from the Oasis system which also provides your hot water.
Both are controlled by the Dometic HVAC controller near the door. Use that controller to set the type of heat: HP or FURN/AQUA and to set the temperatures. Note that the FURN option only recognizes zones 1 and 3 but still heat the whole coach and the FURN requires you to flip another switch as well (see below).
The heat pump uses electricity only (no diesel) but won't work well or at all below about 40 degrees outside temp. The FURN (or AQUA) will work regardless of how cold it is outside. To use the FURN/AQUA, you have to turn the Oasis burner on in your control center above the door as well as turning the Dometic HVAC controller to FURN/AQUA. The switch above the door is in the Oasis section of that panel and is marked "burner" you turn it on. It will start the diesel burner which will cycle on and off automatically as needed to keep the Oasis fluid at the proper temperature. If you are plugged in, turning on either of the AC Heat options ( AC heat I or AC heat I & II) in that same section of the panel will use electricity to supplement the heat from the diesel burner. BUT, in our experience the AC heat options though usually enough for hot water only, will not create enough heat to also power the furnace. So, for FURN (or AQUA) heat you need to turn your Dometic HVAC control to that for zones 1 and 3, AND turn on the burner in the Oasis section of your above door control panel. If you want, you can also turn on the AC heat I or AC heat I & II. I don't think turning on the AC in addition would add to the heat produced or the comfort in the vehicle but presumably it would save a small amount of fuel since some of the heat for the furnace and hot water would come from electricity instead of diesel. Even when we're plugged in and the outside temp is over 40 degrees, we prefer the FURN (AQUA) setting to the HP as it's a little quieter.

I leave my diesel burner on for much of the winter, with the temperature set at 46 degrees in the coach and the basement. This keeps me from having to winterize the coach, since we use it year round. I believe it is cheaper than using the electric heating element. Has anybody ever done any research on this?

Thanks to all, I have this figured out. I took a week off just to learn coach and do upgrades. Changed the little 4" Clarion speakers to Focal 5 1/4" had to use spacers due to depth. Will post picture when I get back to MH but the sound difference is unbelievable!
