Analog output on T3 stuck off after reboot

From what you describe it seems that there is an external master controller setting the output at a higher level priority. This is a rather complicated feature of Bacnet for allowing external masters to control outputs of remote devices.

You can learn more about it here:

Controlling from External Masters using Priority Array

The priority array is a mechanism to support multiple masters in a given system. Normally a controller will be in charge of the outputs on board itself. Occasionally you may want to override the outputs from the logic running in an external master controller, perhaps to do morning startup or load shedding. In emergencies there may be a smoke evacuation mode managed by a fire control system. Priority arrays are read only, if you would like to change the value of an output you write to the presen…

Can you check the priority array of your device as shown here:

Or you can clear the device to go back to the default priority level where the device itself is in charge of the outputs.
