Auxiliary heater switch on dash of 2006 Ventana

Kind of new to this wonderful world of Newmar. I noticed on my dash I have a switch that is labeled auxiliary heater, a black rocker switch next to the visor buttons to the right and overhead fan speed to the left. I believe when the button is in the neutral position it must be off. Push the lower half for low and the upper half for high. In the acc position I don't hear anything running. Just wondering what this controls? Any help would really be appreciated.

Thanking you in advance

Welcome to iRV2.

The aux heater was an option my Dutch Star doesn't have ; but the label is on the dash. The aux heater would have been installed under the bed, for heating the rear of the coach when driving on cold winter days.
With the ignition switch in the ACC position there would be no power to the switch so you'll have to start the coach , turn the switch on high and take a walk to the rear to see if you can hear the fan running.

Thanks again Skip 426,

I went out and started the engine and put the switch on high. I could feel it drawing air from a vent under the washer/dryer so I know it's working. Not certain where it exits but delighted to know that I have the option and it seems to be working. Heading to Utah for a family wedding in several weeks and bet it will come in handy!

Hi Shawnpluke,
I am not familiar with your coach. However, FWIW, in our 2015 Baystar, the electric auxiliary heater unit, fan, air intake grill, and metal heat exhaust vent are all located together, at floor level, in the bedroom. These are housed in a space that is part of a group of wooden, pull-out, drawers. One, thick, black, water heater hose moves hot water from the engine to a small radiator in the heater. A small, electric fan blows air through the radiator, exhausting the heat, and the cool water is returned by another water heater hose back to the engine. The two water heater hoses, that form a big loop, are attached to the under side of the RV and are visible by looking up, under the coach. What I DON'T know, is if the auxiliary heater uses actual radiator water, or if it uses a separate pool of water, a "closed heat exchange unit". -That's all that I know. Have a good trip to Utah. That's a fantastic, scenic state.
