The 5 Series represents some of our best features and efficiencies. The 504W11 is a single stage hydronic geothermal heat pump with OptiHeat technology that's used for high temperature water-to-water applications.
Many 5 Series 504W11 owners use their unit to provide hot water for radiant heat. These systems offer exceptional comfort without moving air. Not only is the floor kept toasty warm, but the entire floor radiates heat to the occupants, furnishings and the air.
5 Series 504W11 units with OptiHeat vapor injection technology are capable of delivering up to 150 degree leaving hot water, which makes it the perfect solution for baseboard or cast iron radiation heating.
The powerful Aurora controls offer two-way communication between components, operating logic, and robust troubleshooting capabilities. Diagnosis and setup and simplified, making service much simpler for the technician.
This optional soft starter reduces start-up amperage by 60% of normal draw to reduce noise, eliminate light flicker, and increase compressor life.
5 Series units come standard with a 10-year warranty on all parts and a 5-year labor allowance for covered repairs. An optional 10-year parts with 10-year labor allowance is also available.
