We do not have a lot of experience in cold weather with our coach and some advice would be appreciated with the temps headed into the 20s Sunday night in our area. I have the coach in our driveway as we get ready to head further south mid-next week. It is not plugged in, just running on the AGS. I have opened the low-point drains and emptied the fresh water tank, looking to blow out the water lines with compressed air if I can figure that out. Should I turn on the oasis furnace to keep the inside above freezing? Anything else we should consider to make sure we do not suffer damage from a hard freeze? Thanks in advance.
 
I would turn on the Oasis...it enables the wet bay heater as well...
 
Definitely turn on the Oasis diesel burner! Set the thermostat to around 50 degrees. That will keep the wet bay from freezing up. To blow out the water lines with air, you need an adapter from garden hose thread to air fitting. Set your air source regulator to 40 psi. Do not use the coach air supply unless you have a way to regulate the pressure to 40 psi or less. With heat in the coach, you shouldn't have to blow out the water lines if the outside temps will only be in the 20s.

That type adapter would be perfect. Where would I look for it?

And, most RV stores will have them. Finally, the plumbing section of any decent hardware store will have the components to assemble one. If you go that route, be sure to chose the longer-nose "industrial" version of the male air fitting, not the short-nose "automotive" style.

Got it, thanks!! Much appreciated.

If I set the thermostat to “Furnace” that is the setting which engages the Oasis system, correct?
 
I don't know how the Dutch Star system works. On our Mountain Aire, we have an "Oasis" panel within the Climate section of SilverLeaf. I would guess that the "Furnace" setting is equivalent. Does it offer the option of using just the electric Oasis elements, and/or the diesel burner?

Any Dutch Star owners that can help @Jwl_Atlanta?

Yes, you should have zone 1 for the front and zone 2 for the rear, with temp control for each, on the furnace setting.

With Diesel Burner ON and/or Electric Burners (AC I/II) and Furnace on the thermostat you should be fine. I think the wet bay heater is automatic and is not associated to the thermostat at all but it does need a heat source from OASIS being Diesel or Electric burners.
