Digital Thermo - did it - easy!

well i did it --- while getting ready to leave these minus temp in Ontario, i changed over the regular therm to a digital one --- it was an easy process and well the furnace works great --- the air conditioner fan hums low and high.

its currently frozen so didn't leave it on for more than a couple of sec to make sure that it could hear the difference between high an low to make sure it was wired correctly.

left the furance on last night -- as i had recaulked the shower --- and this morning the trailer was nice an warm --- no too hot or too cold.

seems to have been a good modification --- additionally, the temp reads the same on the digital therm as the smaller taple top thermo that we have - nice!

so, that being said - if you have not changed it over --- do so -- the directions on her are great!!!!!! thanks fo the help!

Congratulations!

I confess that this conversion scared me a bit more than some jobs for some reason. Must have been the concern over getting all the wiring colors and functions properly matched up. Anyway, when I finally bit the bullet and jumped in, it was surprisingly easy, and like you, I found the results to be more than I expected. The temperature readout is easily read from a distance and is **accurate** beyond my expectations.

For the $21 plus NYS sales tax, I recommend it as an immediate mod rather than waiting for that darned DuoTherm to break! Well worth the money and the few minutes it takes to do the changeover.

Did you have to modify the thermostate to have an A/C high / low switch?

I used the Hunter 42999B that is recommended in the instructions linked in a previous thread on this topic. That thermostat is a stock item at Wal-Mart, I believe.

yes i had to add a small switch to the thermostat - which i did to the side - very small switch to allow low and high fan speed - we seldom use the high speed, but just in case.

i used a honeywell digital thermo that i got for christmas.

quite like it - non programmable one - sorry can't remember the model of it --- and a small $2.00 switch i picked up from radio shack!

Tom, I haven't done the hi/lo mod yet. I was happy with the thing on low, and wanted to think more on how (or if) I will do the hi/lo switch. The instructions posted on the internet show drilling a hole in the shell of the thermostat and adding a little mini toggle switch to have hi/lo functionality. I don't mind doing that once the thermostat is out of warranty, but wanted to think on other possible solutions.

One other possibility is to add a tiny switch box right next to the thermostat on the wall for the hi/lo switch.

Given the fact that most of our camping is in parks without hookups, I don't have the hi/low switch high on my "honeydew" list at the moment.

Congratulations on the Digital Thermostat Mod. Although at first it may seem a little intimidating it is actually a very simple mod. Even adding the Hi/Lo switch is very easy. I am sure you are really going to appreciate this mod on your trip. After I did the mod, I was amazed I didn't do this mod sooner.
