Issue
In a Vista classic network, right click and edit a Xenta 121. Click the load button to load a .zbc file stored on the hard drive and there is no option but to cancel. It will not take a load.
Environment
- Xenta 121
- ZBuilder
- Vista Classic Network
Cause
Because the Xenta 121 type is stored in the Vista database at the time of the creation of the node, it will not allow a fan coil (FC) file to be loaded into a heat pump (HP) or vice versa.
Resolution
- Right-click on the 121
- Go to Properties > XIF File
- Look at the source file listed and make sure it contains either HP or FC and that matches the actual controller.
Alternatively:
- Right-click on the 121 and select Edit
- Click on Load
- Unavailable templates will be grayed out -- see if it is the FC or the HP templates that are grayed out.
Make sure the template .zbc that you are browsing to on the hard drive is set to the same type as the controller that is defined. If necessary, delete the existing controller and add it back as a different type.
