It is an aftermarket installation.
Now the bad news. Dee Howard passed away without finding a buyer for the company so it has been out of business for the past few years. I understand that the estate might have found a buyer and might be back in business in the near future.
Best bet is to do some internet searching for documents or possibly find someone with instructions on its use.
On edit, I just found this info along with a phone #
- The company still exists and is reorganizing
- The goal is to provide service support for existing installations and install new systems
- Current customers can contact the company at 800.879.4277 and talk to a real human (Sam Kopecky)
- Any other inquiry should be directed to info@hpcss.com - I'm assured that every email will be answered
