Try installing the lonhoneywell jar file on your JACE and then rediscover the LON trunk and see if it matches any of the existing LMNL profiles. The fact that you are reading weird values means something could wrong with the controller or you have not done a LON commision and bound the snvts. The values do not have a multiplier and read in degrees C. Also might want to reach out and see if anyone has the pre 3.3 AX version of the Honeywell AX Wizards. It did not require the Honeywell branding on the JACE.
