Inverter RV Air Conditioner

The Atmos is the same, being inside at one of the intake filter locations. From reading one of your past posts, I decided to move mine out to open cabin and left it like that for no particular reason other than things are working great. Now that I have some experience and know what to expect, I may move it back to see if there is any difference.

This brings me to another question on the Cielo. How does it control setpoints... does it override the thermistor reading, or does it just keep adjusting the AC unit temp setting to match what the Cielo is reading if the temps between the two don't align?

The Cielo mimics the unit’s remote utilizing IR to extend control of the air conditioner as a ‘smart’ device. It has built-in temperature and humidity sensors, and provides advanced features via WiFi and the Cielo Home app. Both temperature and humidity parameters can be calibrated to more closely align readings if disparities occur.

Right now my built-in sensor is reading about 5 degrees off in cooling and 10+ in heating. Hopefully the Cielo will be able to work around this for me.

I have noticed that some sensors (both temp and humidity) are more sensitive than others, so despite the calibration I still see a slight variation in readings between devices.

I found a thermisor with a 10' lead.  I used all of it for the route that I ended up using. It got me well away from the unit and out of the airstream of the plenum.  

Your test is limited by the length of the existing thermisor.  None the less if you shield it from the airflow it will increase validity of the effort.
