Issue How can I/A Series G3 be configured to monitor local setpoint changes on the LON based SE7000 Series Room Controllers? Environment I/A Series G3, SE7000 Series Room Controllers Cause Setpoint values on the LON based SE7000 Series Room Controllers are maintained as a network configuration property (nciSetPts).  Local setpoint changes will not be seen at the I/A Series G3 station unless the value is polled or read. Resolution I/A Series R2 had an object (PollSnvtTempSetptCmd) in the lonextras jar that could be set to poll the nci values on a configurable time basis.  The same functionality can be setup in I/A Series G3 through the use of an interval trigger. Open the kitControl palette and expand the ControlPalette - Trigger folder Add an Interval trigger object and configure as Trigger Mode with the Interval required.  The Interval will determine how often the nciSetPts is updated (polled).  The recommendation would be 60 seconds. Right Click on the Trigger and select “Link Mark” Right Click on the SE Room Controller and display the property sheet for the device Locate and Right Click on the nciSetPts parameter.  Select Link From “Name of Your Trigger”. When the link window appears, select Fire Trigger and then select Force Read.  Select OK to complete the link. All setpoints included in the nciSetPts parameter will be updated at the time interval configured to read what has been set at the local device.

Issue  64-061-31 is no longer available and needs to be replaced Environment 64-061-31  TAC valve TAC DWV - PN 6 DN 32  Cause valve no longer available Resolution This old TAC Valve is no longer in production, Schneider Electric do not have any PN6 valves. It's mainly Germany/Austria that uses PN6 valves. Dimensionally they are the same as PN16 valves, the main difference is the wall thickness but in all practical terms it costs more to have two separate tools for each valve PN hence why Schneider and 90% of other suppliers just have PN16 even though they may only ever be used under 6 bar static pressure. As a replacement flanged valve, DN32, the V211 valve is suggested
