Trying to order a controller part number that has been discontinued due to low volume sales / duplicate part numbers.
Continuum IP level Controllers
Discontinuation of duplicate and low volume parts has removed a number of previously existing part numbers from the Continuum catalog. These parts are still available but will need to be ordered as a base unit and then upgraded through Repairs.
The IP level controllers were part of a roll up of the product numbers where low volume part numbers were discontinued. These parts can still be obtained but will need to be chosen from the list of available parts and then get an upgrade through Repairs to add the additional features that may be required. See the Product Announcement on this which includes the currently available part numbers.
