Indoor unit can be serviced while other indoor units within the same piping system are still in operation. To ensure simple and easy maintenance, system tests are available to check wiring, sensors, and refrigerant amount. The integrated control system provides system fault notification. R2-Series is designed to provide the quietest possible operation for both indoor and outdoor environments. Inverter technology and insulation surrounding the compressor provide a rated dBa of 61, a major benefit for hospitals, health care facilities, schools, libraries, and other buildings where quiet operation is critical. The R2-Series two-pipe system simultaneously cools and heats different zones to provide energy-saving heat-recovery operation. Unit captures energy that would otherwise be expelled outdoors and redirects it to a zone with opposite space conditioning needs, thus reducing total energy used by the system to condition all spaces.
