Input sources The SimplyVAV controllers require specific sensors to measure room
temperature, airflow, and discharge air temperature. All sensors are
automatically detected and the programming is automatically set up for the
sensors.
SimplyVAV digital wall sensors
STE-6000 series thermistor temperature sensors
Discharge air temperature sensor
Airflow sensors and pickups
SimplyVAV digital wall sensors —The SimplyVAV digital wall sensors
include a room temperature sensor, a digital display, and a push button
interface for entering setpoints and configuring the controllers. If a
SimplyVAV digital wall sensor is detected, the sensor's temperature is
mapped to the Space Temperature Reference value object as the temperature
input value. See the topic
BACnet objects on page 77 for additional
information on value objects.
The model BAC-8201 SimplyVAV digital wall sensor includes also a motion
sensor to detect when the zone is temporary unoccupied. This is described in
the topic
Occupancy sequence on page 59 .
STE-6000 series thermistor temperature sensors —There are three models
of the STE-6000 series sensors compatible with the SimplyVAV controllers. If
one of the three sensors is detected, the sensor's temperature is mapped to
the Space Temperature Reference value object as the temperature input value.
See the topic
BACnet objects on page 77 for additional information on value
objects.
The STE-6014 and STE-6017 includes also a dial for adjusting the zone
setpoint. If either of these two sensors is detected, the space setpoint is
determined directly from the setting of the dial on the sensor.
The STE-6017 includes a button that when pushed will override the
unoccupied state. This is described in the topic
Occupancy sequence on page
59 .
Discharge air temperature sensor —The DAT sensor is an optional Type-III,
10 kΩ thermistor and is required for VAV heating applications. If the
controller detects that this sensor is connected, then the controller will use
discharge air temperature to determine when to change between heating and
cooling. The DAT sensor input is used also to control reheat. See the topics
Discharge Air Temperature (DAT) limiting on page 62 and Changeover on page
62 .
Airflow sensors and pickups —VAV airflow is calculated by measuring the
high and low duct pressures with the built-in airflow sensor which is
connected to airflow pickup tubes. The high and low pressure measurements
