NEW YORK — WaterFurnace International’s 7 Series 700A11 variable-capacity residential geothermal system offers superior exceptional efficiency, with an EER of 41 and a coefficient of performance (COP) of 5.3. The 700A11 utilizes WaterFurnace’s variable-capacity technology, a soft-start variable-capacity compressor, variable speed ECM blower, and variable-speed loop pump. This allows the unit to scale output to exactly the level needed.

The unit can ramp down to 20 percent of normal operation for ultra-efficient conditioning or up to 130 percent output using SuperBoost™, for periods when extra cooling is needed. The capacity range can even eliminate the need for auxiliary heat, says the company.

The 7 Series also uses Aurora communicating controls, which allow for direct communication among components and continuous optimized operation of the system. With the Aurora Interface Diagnostic (AID) tool, a contractor can plug into an external port to troubleshoot the unit without opening the cabinet.

The product won an AHR Expo Innovation Award in the Heating category.
