Nuvico, the manufacturer of this product, has recently instituted a policy in the United States that disallows the sales of its products direct to the public through online vendors such as this website.  So much so that they will not honor there product warranty if it is purchased by way of any of the vendors listed on their website as 'unauthorized resellers'.  We have attempted to gain 'authorized reseller status' but have not been advised by Nuvico on how to obtain this and our applicatioin has gone without response.  We regretfully inform our customers that to the best of our knowledge Nuvico has opted for amarketing strategy that does not allow for companies like this one to sell their products directly to the end user / public.  Nuvico's current U.S. marketing strategy permits them to only deal with ‘system integrators / installers’.  Thus no longer allowing ‘direct sales to consumers / end users’ based on their current marketing model.  Unless this policy changes, we regret we will not be able to sell this product and request you to look at other products that may prove equal or better on our website.  As we find such products on a per specification basis, we will gladly direct you to them.
