| How it Works

The 75F HyperStat Conventional Package Unit profile is a standalone profile, that provides both heating and cooling conditioning.

The HyperStat provides the flexibility to choose between fully modulating and staged equipment control. Possible equipment configurations include:

  • Single or 2-stage heating/cooling and fan 
  • 1-3 stage cooling but fully modulating heating and fan  
  • Fully modulating cooling, heating, and fan. 

Additional interlock inputs are provided for door/window/keycard sensors. Onboard sensors for CO2 and humidity provide separate damper control for DCV or humidification/dehumidification.   

Sample applications include:

  • Single zone staged CAV RTU for a retail space  
  • Single zone fully modulating VAV RTU for an industrial setting  
  • Split unit for a small warehouse office. 

The diagrams below show the application of the Deadband and Hysteresis Band and their role:

The profile also allows the user to set IAQ parameters that can be displayed in the HyperStat device's home screen.                   

Note: Only two of the IAQ parameters can be set at a time, to be displayed in the HyperStat device's   home screen, or none can be enabled.

  • Click Set to confirm the configuration changes.

The zones paired with CPU profile is displayed in the CCU as below.
