VAV with Reheat (HW or Electric)
Features
• Configurable flow sensor range to match QVM sensor.
• Dynamic minimum airflow input allows demand controlled ventilation.
• PID control minimizes offset and maintains tighter set point control.
• Standby mode enables energy savings during occupied hours for rooms that are not always
used. When occupants are sensed, the controller quickly responds to maintain comfort levels.
• Diversity control, through a demand limit input, maximizes comfort by maintaining even air
distribution to all zones during morning warm-up or pre-cool operation.
Sequence of Operation
In this core configuration, the Predator operates perimeter heat, the reheat coil and the primary air
damper to maintain required room temperature and ventilation conditions.
Occupied Mode
The Predator applies occupied settings for the space temperature setpoints and the primary airflow
minimum. The typical result is continuous ventilation, with heating or cooling automatically selected
to maintain comfort.
Cooling
The cooling PID maintains the measured space temperature at the occupied cooling setpoint by
modulating the primary airflow setpoint between the maximum cooling flow and the minimum
cooling flow.
The active minimum airflow may be dynamically adjusted over the network according to air quality
considerations.
The primary airflow PID maintains the measured airflow at the varying setpoint by modulating the
position of the primary air damper.
The reheat coil is off.
Perimeter heat is off.
Lighting is on.
