Secon3:InstallingtheRoomSensors
An airow sensor is incorporated as one of the inputs to the controller. Remove the plugs and connect the tubing from the pitot
assembly to the airow sensor inputs next to the drive hub.
EZvavSensors:
This applies to EZvav digital display wall sensors connected to EZvav controllers.
Choosingasensorlocaon
Install the sensor on an inside wall where it can sense the average room temperature. Avoid locaons with direct sunlight, heat
sources, windows, air vents, and air circulaon obstrucons such as curtains or furniture.
For models with moon sensing, see the topic on the page 12, Planning for moon sensing.
Rough-inpreparaon
Complete rough-in wiring at each sensor locaon prior to sensor installaon. This includes the following items:
• If required, install an appropriate backplate.
• Route an Ethernet connecng cable from the sensor to the controller locaon.
• Maximum cable length is 75 feet (22.9 meters). Plenum-rated preassembled cables are recommended.
Mount the sensors
To install the sensor on a mounng base, do the following:
1. Turn the Allen screws in the base of the sensor clockwise unl they clear the case. Swing the sensor away from the

2. Route the Ethernet cable through the mounng base.
3. Fasten the mounng base directly to a 2 x 4 inch (51 x 102 mm) outlet box or a backplate with the Allen screws toward
the oor.
4. Insert the Ethernet cable coming from the base into the sensor.
5. Place the top of the sensor over the top of the mounng base and swing it down over the Allen screw brackets. Be
careful not to pinch any wiring.
6. Turn the Allen screws counterclockwise unl they back out of the mounng base and engage the case of the sensor.
Operaon
The sensor will become operaonal as soon as it is connected to an operaonal controller. See the following pages to change room
set points or congure a EZvav controller with the sensor.
Maintenance
Remove dust as necessary from holes in top and boom. Clean the display with so, damp cloth and mild soap.
Planningformoonsensing
For moon sensing models only — Mount the sensor on a wall that will
have an unobstructed view of the typical trac in the coverage area. When
choosing a locaon, do not install the sensor in the following areas.
• Behind curtains or other obstrucons.
• In locaons that will expose it to direct sunlight or heat sources.
• Near a heang or cooling inlet or outlet.
The eecve detecon range is approximately 33 feet (10 meters). Factors
that may reduce the range may include the following items.
• The dierence between the surface temperature of the object and
the background temperature of the room is too small.
• Object movement in a direct line toward the sensor.
• Very slow or very fast object movement.
• Obstrucons in the shaded area of the diagram
Typical moon sensing coverage.
False detecons may be triggered by any of the following
condions.
• The temperature inside the detecon range
suddenly changes because of the entry of cold or
warm air from an air-condioning or heang unit.
• The sensor being directly exposed to sunlight, an
incandescent light, or other source of far-infrared
rays.
• Small animal movement.

Secon5:ConguringtheControllers
This topics in this secon are advanced topics for control technicians and engineers.
The conguraon funcons that are accessible through an STE-8000 series sensor are all of the values and sengs that are
entered during the installaon and commissioning of a VAV terminal unit. Typically, these funcons do not change aer the
installaon and commissioning process.
To set up the conguraon funcons, you will need the following items and informaon.
• Details about the VAV terminal unit including the conguraon for fans and reheat.
• An STE-8001W36 or STE-8201W36 to use as a conguraon tool.
• The building automaon system plans for controllers connected to a network.
Users may change the acve heang and cooling set points without accessing the conguraon funcons. This procedure is
covered in the topic Changing the Room Set Point on page 13.
Note: The instrucons for the conguraon funcons cover all of the funcons that an STE-8000 sensor can set up in the EZvav
series of controllers. Not all funcons are available on every model of controller.
