STAGED AIR VOLUME SAV™ SYSTEM The new Carrier® Staged Air Volume SAV™ System saves energy and installation time by utilizing a Variable Frequency Drive (VFD) to automatically adjust the indoor fan motor speed in sequence with the units cooling, heating and ventilation operation. Comfort Control • ompared to single speed indoor fan motor systems, C can save 25%+ in energy to help reduce operating costs. • mproves unit Integrated Energy Efficiency Ratio (IEER). I • ay qualify for utility rebates. M • elps lower indoor humidity level at lower speed by improving H air over coil efficiencies. • ndoor fan speed is matched to cooling staging for better load I profile control and occupant comfort. Code Compliant Simple Set-Up and Operation • omplies with ASHRAE 90.1 2010 standard for Single Zone C Variable Air Volume (SZ-VAV) control. • eets requirement for California Title 24 indoor fan M speed control. • arrier exceeds ASHRAE 90.1 2010 standard by offering the C SAV™ System on popular 7.5 and 8.5 ton models. • re programmed VFD allows simple fan pulley adjustments P to establish fan performance settings. • o special training or certified start up is required. N Operating Sequence • re programmed, tested and installed at the factory. P • oft start capability eliminates high in-rush air volume S to help reduce noise in duct systems during speed change. • rovides indoor fan motor over current protection.
