Product Summary
The Daikin 5MXTH40AVJU9 is a 40,000 BTU (3.33 ton) Aurora MXTH multi-zone heat pump outdoor unit with 5 ports. One outdoor unit runs two to 5 indoor units, and each room gets its own temperature control.
Aurora models are Daikin's cold-climate line. This unit keeps heating down to -13°F outdoors, and its coil carries an anti-corrosion coating. The MXTH version adds a factory-installed drain pan heater that keeps defrost water from freezing in the base pan, which matters in snow and ice country.
With non-ducted indoor units it carries AHRI Reference No. 217747243 and is rated at 20 SEER2, 11.7 EER2 and 9.5 HSPF2. Ducted and mixed ducted/non-ducted combinations have their own AHRI ratings, listed below.

- Up to 5 zones: connect 2 to 5 Daikin indoor units
- Low ambient heating: heats down to -13°F outdoors
- Drain pan heater: factory installed to stop ice build-up after defrost

- Long line sets: 262 ft total, 82 ft per room, 49 ft max height difference
