Electrical Package with Single Point Connection

• All motors wired to starters.
• Accepts contact inputs for supply fan start/stop, wheel start/stop and unit start/stop.
• Multiple options on input voltage to units:

• AQFlow Airflow Measuring System
  • Simpler, more accurate system balancing in just five minutes.
  • Easy measuring and adjusting of outdoor and exhaust air quantities.
  • Accurate airflow ( /-6%) for the stand-alone FV unit or when mounted to a package rooftop unit where measuring outdoor air quantities is difficult.
  • Reduced calls to engineers regarding air quantities.
  • Peace of mind that proper ventilation is being provided to building occupants.
  • Quick detection of problems like dirty filters, motor failure, power outage, etc.
  • Meets intent of current ASHRAE standards for monitoring delivered fresh air quantities.
  • Airflow quantities can be displayed on AQFlow.
• Electric Preheat (Optional)
  • An electric preheat coil can be provided to avoid frosting conditions for installations in cold climates, which have high indoor humidity design conditions.
• Thermostat Frost Protection (Optional)
  • Thermostatic frost control allows the entire FV unit to be turned off at a predetermined temperature when electric preheat is not desired.
• Control Package (Optional)
  • Stop/Jog Economizer allows the wheel to be stopped automatically during mild outdoor temperatures with periodic brief rotation to maintain the self-cleaning feature of the heat exchanger.
  • Wheel Frost Protection allows the wheel only to be stopped by the stop/jog economizer at a predetermined outdoor temperature in applications where a preheat coil or thermostat shut-off of the FV unit is not desired.
  • Sensor can provide an alarm signal indicating failure of the wheel rotation.
• Remote Indicating Panel (Optional)
  • SEMCO remote indicating panel provides a convenient and attractive option for monitoring the FV Preconditioner.
  • Remote mounted Indicating panel provides status indicators for the following:
    - Unit Power On
    - Wheel Rotation Alarm
    - Dirty Outside Air Filter
    - Dirty Return Air Filter
  • Field wiring is only required from the remote panel to a low voltage terminal strip factory mounted on the FV unit. Remote indicating panel includes a junction box and plaster ring for recessed or surface mounting.
  • Note: Control Package Option must also be selected for Wheel Rotation Alarm function.
• Dual Wall Construction (Optional)
  • Interior of FV Preconditioner is lined with 22 gauge galvanized sheet metal.
