Secon 1: About the Controllers
This secon provides a descripon of the EZvav series of controllers. It also introduces safety informaon. Review this material
before selecng, installing, or operang the controllers.
The EZvav series of controllers are an easy and unique approach to operang a wide variety of VAV terminal units. The integrated
actuators, internal airow sensors, and wide variety of applicaon programs make these BACnet Applicaon Specic controllers
ideal for either new or retrot installaons.
The controllers feature simple, menu driven setup choices when used with a EZvav digital sensor. No special programming skills
or soware tools are required to choose applicaons, enter set points, set network addressing, and balance airow. All opons
can be set by using a STE-8001W36 sensor and can be installed as the permanent room sensor or temporarily connected as a
technician’s service tool.
All models are BACnet Applicaon Specic Controllers that are ready to connect to a BACnet MS/TP network. Device instance,
MAC address, and baud rate are set from an STE-8001W36 without special soware.
Model BAC-8001-36 is supplied with inputs, outputs, and sequences of operaon for the following funcons.
• Single duct heang and cooling VAV.
• Automac heang/cooling changeover including morning warm up.
• Occupancy setback—requires STE-8201W36.
• System diagnosc indicators.
• Airow balancing.
Model BAC-8005-36 and BAC-8205-36 are supplied with inputs, outputs, and sequences of operaon for the following funcons.
• Single duct heang and cooling VAV.
• Modulang, oang, and staged reheat.
• Series and parallel fan control.
• Automac heang/cooling changeover including morning warm up.
• Discharge air temperature liming.
• Occupancy setback—requires STE-8201W36.

SafetyConsideraons
Nailor assumes the responsibility for providing you a safe product and safety guidelines during its use. Safety means protecon to
all individuals who install, operate, and service the equipment as well as protecon of the equipment itself. To promote safety, we
use hazard alert labeling in this manual. Follow the associated guidelines to avoid hazards.
Note: Notes provide addional informaon that is important.
Tip: Provides programing ps and shortcuts that may save me.
Secon2:InstallingtheControllers
This secon provides important instrucons and guidelines for installing the Nailor EZvav controllers. Carefully review this
informaon before installing the controller.
Installing Nailor EZvav includes the following topics that are covered in this secon.

SengtheRotaonLimits
Nailor EZvav controllers are manufactured for a damper that rotates 90 degrees from open to close. If the VAV damper is not a 90
degree damper, set the rotaon limits to 45 or 60 degrees before mounng the controller.
DANGER represents the most severe hazard
alert. Bodily harm or death will occur if danger
guidelines are not followed.
CAUTION indicates potenal personal injury or
equipment or property damage if instrucons
are not followed.
WARNING represents hazards that could result
in severe injury or death.
CAUTION Seng rotaon limits that do not
match the VAV damper may result in improper
operaon or equipment damage.

Figure2-1 Controllerrotaonlimitselecons
To set the rotaonal limits, do the following:
1. Turn the controller over so you have access to the back.
2. Manually rotate the actuator fully clockwise as viewed from the back.
3. Remove the stop screw from its storage locaon and clean any debris from the threads.
4. Insert the screw into the correct stop posion hole.
5. Tighten the screw only unl the head touches the plasc in the boom of the recess.
MounngonaVAVTerminalUnit
Mount the controller inside of a metal enclosure. To maintain RF emissions specicaons, use either shielded connecng cables
or enclose all cables in conduit.
Mount the controller directly over the damper sha. A minimum sha length of 2.0 inch (51 mm) is required.
Note: Nailor EZvav controllers are designed to directly mount to 3/8 to 5/8 inch (9.5 to 16 mm) round or 3/8 to 7/16 inch (9.5 to
11 mm) square damper shas.

2. On the controller, press the gear clutch buon and rotate the drive hub in the same direcon that closed the
damper. Turn the hub unl it reaches a rotaon limit, then rotate 2° in the opposite direcon and release clutch.
3. Loosen the nuts on the V-bolt unl the damper sha can t through the collar.
4. Place the controller over the damper sha.
5. Finger ghten the nuts on the V-bolt to posion the sha in the drive hub
6. Center the mounng bushing in the mounng tab and fasten it with a #8 sheet metal screw.
7. Evenly ghten the V-bolt nuts on the drive hub to 30-35 in-lbs (3.34 – 3.95 N.m).

ConnecnganAirowSensor
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.
Figure2-3 Airowsensorinputs
Diamond ow sensors are supplied by Nailor as part of the VAV terminal unit. If a sensor is needed, choose a sensor listed in the
topic Accessories and Replacement Parts on page 48. For more informaon on Nailor’s ‘Diamond Flow’ Sensor, see page 48 or
refer to Nailor website.
ConnecngInputsandOutputs
Nailor EZvav series controllers have precongured inputs and outputs to support only the supplied programs and applicaons.
• For input and output connecon informaon, see the topic Applicaon drawings on page 29.
• To connect room temperature sensors, see the topic Connecng room temperature sensors on page 9.
• To connect a DAT sensor, see the topic Connecng a DAT sensor on page 10.
• For the BACnet object descripons of the inputs and outputs, see the topic BACnet objects on page 44.
ConnecngRoomTemperatureSensors
Connect any of the following sensors to the RJ-45 thermostat and sensor jack. The controller automacally detects the type of
sensor. No programming or conguraon is required.
• STE-6014W36
• STE-8001W36
• STE-8201W36
Connect the controller to sensors with standard Ethernet cables up to 75 feet long.

ConnecngaDATSensor
The Discharge Air Temperature sensor is required for automac changeover and for VAV terminal units with reheat.
Figure2-5 Dischargeairtemperaturesensorlocaon
Connect a 10 kΩ, Type 3 thermistor temperature probe to the discharge air temperature input. The input includes the internal
pull-up resistor. An STE-1401 sensor is suitable for this applicaon. Follow the instrucons supplied with the sensor for installaon,
or refer to pages 11-12 for this informaon.
• For DAT liming and reheat, install the sensor in the airow aer the reheat secon. See the topic, Advanced opons on
page 21 to enable discharge air temperature control.
• When the DAT sensor is used only to detect primary air temperature, the sensor can be placed in either locaon shown in
the Figure Discharge air temperature sensor locaon.
Figure2-6 Dischargeairtemperatureinputdetails
ConnecngPower
The controllers require a 24 volt, AC power source. Use the following guidelines when choosing and wiring transformers to the
controller.
• A Class – 2 transformer is supplied with each unit.
Connect the 24 volt AC power supply to the power terminal block on the lower right side of the controller. Connect the ground
side of the transformer to the ground terminal and the AC phase to the phase terminal. Power is applied to the controller when
the transformer is connected to power.
