The SIMPLE way to "fix" this type problem---You like 70 degrees in the RV but it seems the RV gets to 71/72. Just set the tstat at 68 degrees and forget attempting to adjust the Anticipator. Sorry, but this type problem is NOT a problem. Just people trying to waste their time obsessing over something. In 38 years as a tech, I have NEVER had to or had a customer state he seemed to have a problem with the furnace that required the anticipator be adjusted. Also, since the majority of Wall RV tstats are electronic, that stops this type problem and has for over 25 years. Doug
