Make space temperature Calibration with Niagara AX

[nuclear rabbit]

O.K. I have Niagara AX. With a Lon Based stat pulled into my JACE. The actual apacetemp is about 3 degrees lower than what the space sensor is reading. I know there is a way to enter an adjustment into the spacetemp point, I just don't remember how. Can anyone help me?

On a Lon based stat I would think the calibration needs to be done at the stat, if not the stat will still see the wrong value and control by it. To change a reading AX side in the point properties under facets, conversion, linear and add offset value.

...ProxyExt/Conversion/Linear ... and add offset value.

Usually there is a SNVT 'SensOffset' or something like that in the Lon wall sensor itself.

I know that it can be done through the plugin for Honeywell XL-10's and a few Thermokon sensors I have come across.

If this device is the unit controller and not just a network temperature you will want to find the calibration snvt like Keith mentioned. Otherwise by adjusting the proxy extention, you will only be calibrating what the user sees, but not the actual temperature control.

I attempted to adjust the space temp by going ...ProxyExt/Conversion/Linear ... and add offset value. My space temp reading went from 78.4 to 26. I have a Bapi lon stat pulled into a Circon controller (which is controlling a rooftop unit) and this is pulled into our Jace. I do not know where to find my lon snvt's for this stat. Any suggestions?

There should be a "nciTmpOffset"

I think it was converted to Celsius, you need the offset point to be a snvt type 147.

Do you have the Circon wizards?? You should be able to do it through the wizards.
