Key Benefits
 
Airflow Distribution
Airflow is outstanding. Precedent™ can replace an older machine with old ductwork and, in many cases, improve the comfort through better air distribution.
 
Cabinet Integrity
For added water integrity, Precedent™ has a raised 1 inch lip around the supply and return of the downflow units to prevent water from blowing into the ductwork.
 
Coil Guards
Coil guards protect condenser coil during shipping as well as hail, vandals, wind, etc. Toolless design lends itself to ease of maintenance in cleaning coils.
 
CO2 Sensor — Demand Control Ventilation (DCV)
Demand-controlled ventilation (DCV) is a control strategy that responds to the actual demand (need) for ventilation by regulating the rate at which the HVAC system brings outdoor air into the building. A CO2 sensor measures the concentration (parts per million, ppm) of CO2 (carbon dioxide) in the air. As the
CO2 concentration changes, the outside air damper modulates to meet the current ventilation needs of the zone. The CO2 sensor kit is available as a field installed accessory and wires directly to the Symbio 700 controller.
 
CompleteCoat™ Condenser Coil
This optional coated coil provides excellent corrosion resistance as well as uniformity of coverage and coating thickness.
