  Looking to replace analog/lever thermostats

  Posted by Dick on November 17, 2015 at 2:32 pm

  We have at least three 1999 vintage analog thermostats in our coach. Two of them control the heat from the Webasto (one in bedroom, other in kitchen) and a third is in the water bay to control the 110 volt heat gun/blower that heats the water bay.

  The two controlling the Webasto have the tiny little levers to set the temp. The one in the water bay has a dial with apparently “off” being in the furthest counter-clockwise position.

  I would like to upgrate these to a digital thermostat. In the case of the one in the water bay I would like to get one that has a range that goes low (why turn the heat on when the temp in the water by goes to 45 or 50 or 55 degrees. I also would like to eliminate the potential having the thermostat in the “off” position.

  Has anyone changed our their thermostats? I found this:

  http://www.amazon.com/Honeywell-TH1100DV1000-Pro-Digital-2-Wire-Heat/dp/B00H6ARNXO/ref=pd_sim_60_4?ie=UTF8&dpID=31DFLCKWwJL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=1GT3KEGR56ZG0V71FNBX

  I think it will probably get the job done. Low set point is 40 degrees which I think is good for the water bay.

  What has anyone else used.

  The problem is that the t-stat you need to replace them have to be “dry contact” units that operate on battery power rather than 24vac, like household dig t-stats do. They are few and far between, and the one’s we have used in the past tend to be problematic. Many we put in new coaches have since been replaced by the vary one’s you seek to replace lol. The brand we used were Aube, a european looking very cool looking t-stat, but like I said, proved to not be all that reliable in the long-run.

  At least you know what to look for now so you get something that can function to control the aquahot zones.

  Thanks Ben!

  Nothing seems to be easy. Always a “twist”.

  I was wondering about power to the thermostat, you answered the question.

  I have used this one on several coaches with multiple zones Aquahot systems and worked very well.
