Replacement Rooftop 2009 Product Training

OVERVIEW History of Multizone The multizone unit was very prevalent in the 1960’s and 1970s. They had the ability to heat and cool different spaces within a common building. These units were very energy inefficient. Many of the major manufacturers built multizone equipment like Nesbitt, Lennox, Trane, Carrier, Mammoth. Plus there were a few others who produced equipment. These units were very inefficient due to the components they used. Each manufacturer built there units little differently. Since these units are reaching the end of their life cycle, how do you replace the unit without a lot of field labor? Also, how does a customer get better efficiency?

How does RMZ help solve this issue? The RMZ product matches the footprint of several manufacturers.
