Compatible indoor units

This is an outdoor unit. You choose its indoor heads separately - up to the maximum this condenser supports - and you can mix room sizes and styles across the zones. The models below are the heads this unit is documented to pair with.

  • Wall-mounted air handlers

    9k, 12k, 18k

    Model numbers
    • 9k: 048-TC-9K2VR-IN
    • 12k: 048-TC-12K2VR-IN
    • 18k: 048-TC-18K2VR-IN

Sizing note: do not just add up the rooms. Multi-zone condensers have a maximum total connected capacity, and connecting more head capacity than the unit is rated for is a common installer mistake that hurts efficiency and comfort. Match total head capacity to the condenser's rating.

Frequently asked questions

Can I install the Della Vita Series Multi-Zone 3-Zone 28,000 BTU R-32 208/230V (048-TCQ-MODU-1D3) myself, or do I need a pro?
Della Vita Series Multi-Zone 3-Zone 28,000 BTU R-32 208/230V (048-TCQ-MODU-1D3) is built for professional installation: the line set must be flared, evacuated, and charged, which requires EPA-certified refrigerant handling. Installing it outside the manufacturer's requirements can void the warranty, so budget for a qualified HVAC installer.
Will the Della Vita Series Multi-Zone 3-Zone 28,000 BTU R-32 208/230V (048-TCQ-MODU-1D3) keep heating in a cold winter?
The manufacturer publishes 21,000 BTU/h of heating output at 5F. Rated heating operation extends down to -13 F. Certified heating efficiency is 10 HSPF2. Match those numbers against your climate's design temperature - in cold regions, output at 5F matters far more than the nameplate capacity measured at 47F.
What electrical circuit does the Della Vita Series Multi-Zone 3-Zone 28,000 BTU R-32 208/230V (048-TCQ-MODU-1D3) need?
Published electrical requirements: 230 V voltage, 16 A minimum circuit ampacity, and 25 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
How far can the outdoor unit be from the indoor head?
The published maximum line-set length is 197 ft, and the included line set comes pre-charged for 25 ft. Longer runs than the included set allows typically mean added refrigerant and a pro visit, so measure the planned routing before ordering.
