Low ambient performance with LGRED° heat technology is included in Multi V 5 Air Source Units produced after February 2019.
TC: Total Capacity (MBh); SHC: Sensible Heat Capacity (MBh).
Cooling range with the Low Ambient Baffle Kit (sold separately) installed on the outdoor
unit(s) is -9.9°F to +122°F, and is achieved only when all indoor units are operating in
cooling mode. Does not impact heat recovery system synchronous operating range.
The System Combination Ratio must be between 50–130%.
Rated capacity is certified under AHRI Standard 1230. Ratings are subject to change
without notice.
Current certified ratings are available at
www.ahridirectory.org
.
