[QUOTE=RJS3791RD;524635]Good evening. I have been following along with this posting. I have a 2022 3791RD and Legacy which has the iN·command system. I also have the heat pump on rear unit. It’s cold right now in Pennsylvania.
Unlike the previous post, both of my temp sensors are showing 41 degrees.[/QUOTE]
In your case with both remote temp sensors reading exactly the same temps.. and they are located in two different areas of the RV you have a somewhat unique issue.
** That is assuming the actual inside temps are not at 41 degrees.
Zone 1 and Zone 2 roof AC units each have their OWN separate remote temps sensors, the gateways are separate, etc.
The common denominator for your system is the In Command BCM, Display, CANBUS lines connecting Zone 1 and Zone 2 from the gateways down to the BCM..
If your version of In Command is the Global Connect.. vers: NCSP3, NCSP35 then I would be looking at the BCM and make sure the (EOL) End of Line terminating resistor is in place.
It will be found on the BCM.
This OR a loose connection on the CANBUS lines could cause what you are seeing.
OR.. have you checked you version of Firmware loaded for your system to see if you have the latest firmware?
This link is for the Global Connect versions ONLY: identify your system and then take a look see for your specific version and you will also see where the EOL terminating resistor is installed.
