The STR-150 is only compatible with Xenta 100 series controllers that are software version 1.2 or later.

If a wall module with display is required for a Xenta 100 controller with software that is older than version 1.2 there are two possible solutions:

  1. An identical Xenta controller can be purchased with the latest software version to replace the old controller.
  2. An STR-350 stat can be used and connected to the Xenta controller via SNVT bindings.
