The Priva Compass keeps a log of all changes that have been made to the user settings.  This log records the date and time a change has been made, which setting was changed, what the old value was and what the new value is.  This information is stored in an audit log.

In order to view the audit log, use the following procedure.

1. Enter the Gateway setup. To enter the gateway setup, you will need to enter the PIN code. This is the code that allows you to get into the installation menu and has been set by your installer. 
2. In the Settings tab of the Gateway setup you will see all the controllers that are connected to the gateway. Click on the Device Setup button of the controller you wish to see the log of.
3. Click on the sprocket on the page to get to the application setup screen.
4. Click on the Diagnostics tab to access the diagnostic screen.
5. Click on the Audit Log to download the audit log to your PC. The audit log is saved as a zipped file.
6. The audit log can be viewed with any text editor.

You will notice that the audit log is cryptic. It was originally made to give a internal technical report of the changes that were made to each controller.  This information can also be of assistance to our installers so we made this available to them.   Some of the data is confusing, but here is an explanation of them.

Odd numbers in settings

The numbers that you see changed are the internal numbers that the Compass uses.   Most of them are clear but there are some that are confusing.  For instance temperatures are always set in Celsius regardless of whether the Operator is running in Fahrenheit or Celsius. Where it gets more difficult is when you start looking at other things like flow numbers.  For the user, the values can be displayed in cubic meters per hour(m3/h) or gallons per minute (gpm) but in the audit log, they are shown in cubic meters per second (m3/s). So you will see something like this:

zone 1 \ water flow sensor 1 \ minimum flow alarm level changed from 2.77778e-05 m3/s to 0.000277778 m3/s

Time Settings

The time settings are even more confusing. Internally the Compass uses UTC  (Universal Time Coordinated).  This is done for the chart history logs and since UTC does not switch due to daylight savings time, it resolves the problem having two bits of data logged at the same time when you change the clocks back an hour. The times are also set in milliseconds.  So if you set a time to 8:00 am EST, it will add the 5 hour difference between Eastern Standard Time and UTC since UTC is based on British time and there is a 5 hour difference.   So the internal time would be 13:00 If you convert that to seconds (13 X 3600) , you will get 46,800.  But the time is actually sent in milliseconds so the value you will see is 46800000.

Text settings

When text values are changed, it displays the numerical representation of the text. So when you see

zone 1 \ physical vents control 2 \ vent manual override control changed from [1,0,0] to [1,0,1] 

it means that the override setting was changed from OVERRIDE (1,0,0)   to AUTOMATIC  (1,0,1).

Inputs and outputs

When you set an input or an output, the log file shows the numerical representation of the physical channel. So if you set a vent open channel, you will see:  

zone 1 \ physical vents control 3 \ vent open channel changed from {0,0,0,0,[0,0,0,0,0,0]} to {0xc07a0a084a,0,2,0,[0,0,3,33,33,0]}

rather than the actual channel.

The GUID 

The long number that you see at the end of each line in the audit log is the GUID (Globally Unique Identifier) of the particular setting that was changed. Every single setting in your Compass system has a unique reference

The example you gave can be broken down in this way

{0002-8301-8201-800f4319-8000033b}
