I just found this message, posted on the Yahoo Proliphix group:
Hello all,
As most of you know this is an unmoderated forum for users to shares questions and experiences with each other. If you have questions regarding products, you should email to sales@proliphix.com or if you have support questions you can use support@proliphix.com. With that said here is our product availability update:
Our 1st generation products the NT series and TM series models have been discontinued as of this spring as we have exhausted our last supplies of those devices. We introduced our 2nd generation product family called the IMT series last summer. In that family there is the IMT550 which is targeted to commercial uses and the IMT350 which is normally used in residential applications.
As some of you have noted the IMT350 was removed off our website for a while due to some unexpected part shortages which made it impractical for us to take orders on the IMT350 since we did not have a clear date when the units would ship.
We now know that the IMT350 will be available in June so it will again be listed on the website in that time frame. Please check our website in June for more detail.
We appreciate you interest in our products and look forward to continue to innovate and provide solutions that will allow you to manage your enegy control needs.
Best Regards,
Larry Sargent
