Issue
How and when does a Xenta 121 resynchronize floating control outputs?
Product Line
TAC Vista, EcoStruxure Building Operation
Environment
Xenta 121 - All versions
Cause
Documented reasons for floating control resynchronization on a Xenta 121 controller.
Resolution
There are 3 events that cause a Xenta 121 to resynchronize its floating control output logic. These reasons are:
- After a restart of the controller from a power cycle or reset command. The resynchronization is randomly initiated within the first 42 minutes after this restart. Testing shows an average of 20 minutes.
- After the controller is powered up and has done it's initial resynchronization, it will resynchronize every 18 hours there after.
- Commanding the snvt_switch input nviDOResync value member to >0, and the state member to =1
Please see Programming SNVT_Switch in Menta for instructions on how to program snvt_switch in Menta.
