Dometic Thermostat

Hi All

Just bought a new 2013 FR Georgetown 335 Class A going full time.

We have a Dometic thermo for control but the AC seems to run allot. It does shut off when it reaches my coolness and the fan keeps running.

Is there a way to get both compressor and fan to auto on/off?
I went thru all my paperwork 2x and cant find anything on the thermostat

My thermos is like this.

I have one that looks like yours. Is the fan setting on auto? Please check that first because the fan should stop running a few minutes after the AC turns off at the desired temp. You don't say were you are, if it is hot, the AC will run a lot. The RVs don't have a lot on installation, 2 inch walls, so in the summer heat, with no shade, it will run for a long time. I spend 3 days at the Excapee campgroung in Livingston, Texas last month and the AC run and ran and I have two ACs, but no shade and it was 95 or more for those days. Good Luck

On page 7, it explains how to set your fan to "Auto".

It goes on to say that, in "cool" mode, when auto fan is selected the fan speed will vary depending on the difference between the temperature set-point and the room air temperature. In auto fan the compressor and the fan will cycle On and Off with the thermostat.

When we got our TH I went through all the manuals and tried to find a PDF on-line and when I found them downloaded them (found most everything btw). I now have them all stored on my iPad and have access to them all via my iBooks.

You could load them to a thumb drive and use with a laptop too.

Have been doing this with all our home appliances for years now, that way when I need a manual I can find it easily on my network drive.

When we sold our place in Colorado I made a cd for the new owners with all the manuals for that house on them (couldn't find all the hard copies).

Same thing I do. SOOOO much easier to find manuals that way. I know the old guys like their paper versions. I keep the paper at the RV and the pdf version at home computer. Sorry, no Ipad for me yet. I do like this picture however.

I have an old Texas Instrument laptop running Microsoft 95 with MS-Bob installed and yes it still works. When I found out Bill Gates future wife designed BOB, it all made sense. IF you have interior decorating skills, BOB is for you!
