Table 1: Summary of Resolved Issues
CR Number
The user interface may display stale values when you release an operator override command on a field controller that is running a very large complex N2 control application.
When a ROMUTEC module is powered down for a brief period of time, the field controller that is monitoring the unit is not detecting the module’s offline state. This situation can cause the BOs and AOs of the ROMUTEC module to be in an incorrect state.
Field controllers go offline after you perform a site discovery. Cycling power on the controllers returns the units to normal operation.
When you use MAP 4.2 connected on the SA Bus of a field controller to commission that controller with the Programming and Commissioning Tool (FX-PCT), the commissioning session fails with a communication error.
The CPO Chiller Selector Min On Time needs to allow for longer times (up to 8 hours).
