a. The ":Tracer" property is used to view the sent data. The ":Ref" property (same prefix) is used for referencing.
b. Non-proprietary. Network variable and Tracer Summit property are supported.
c. The variable is mandatory, but each of the elements of the variable are optional.
d. Two separate properties: one for cooling, one for heating.
e. Implemented in a proprietary manner but is available to others through public nvi/nvo.
f. Trane is proprietary. Trane
g. Unit Status is mandatory, but not all elements of the structure are required.
h. Air valve position during heat mode.
i. Total reheat capacity, discrete values for staged reheat capacity.
j. Air valve position during cool mode.
®
k. Used by Tracer VV550/551 controller to report the primary air temperature. Could be either nviSourceTemp or the auxiliary
temperature when configured to measure the primary air temperature.
