VAV Flow Controllers Actuators analog electronic controllers
A. GENERAL
The electronic analog C51 VAV flow controller-actuators are pressureindependent combination controller-actuators designed primarily for use on variable air volume terminal units. Air flow is sensed by using a differential pressure airflow sensor, such as the Anemostat Velocity
Wing sensor. Designed with an on-board flow-through sensor utilizing twin platinum resistance temperature detectors, these models are capable of controlling a velocity setpoint with an accuracy of 3%.
The C51 offers full range flow control of VAV terminal units when used with the CTE–5100 series room ther mo stats. Air flow control limits may be set at the thermostat or internal to the C51 (see applicable control package). The actuator section provides adjustable stops, magnetic clutch and a gear disengage ment button.
On older models, a tri-color LED indicates green for opening, red for closing and white/off for satisfied damper positions. On newer models, two separate red and green LEDs indicate opening and closing.
Typically, the C51 is factory set for a CCW damper rotation to close, but this should be verified based on the type of air terminal.
A
B. MOUNTING
The CSP–5001/5002 is designed to mount on a standard
1/2" (13 mm) diameter shaft or a 3/8" (9.5 mm) shaft using the optional HFO-0011 adapter.
Standard Instructions
1. Slide the CSP–5001/5002 directly onto the 1/2" diameter damper shaft. The shaft must extend a minimum of 1-3/4" from the mounting surface.
2. Place the non-rotation bracket (supplied) on the non-rotation tab. Leave a gap of 1/8" between the bottom surface of the
CSP-5001/5002 and the bracket to allow for play during operation (see illustration).
3. Attach the non-rotation bracket to the mounting surface using (2) #8 or #10 self-tapping screws (not included).
4. Depress the gear disengagement button and:
A. Rotate the drive hub until the indicator stops at the “90” mark if the damper is clockwise to close.
B. Rotate the drive hub to the “0” mark if the damper is counterclockwise to close.
5. Position the damper to full open.
6. Torque the two 5/16-18 setscrews to 75 - 85 in. lb.
7. Depress the gear disengagement button and rotate the drive hub/damper to the closed position.
8. Loosen the adjustable end stop, position against the damper position indicator, and retighten.

C. WIRING
1. Remove the C51’s wiring access door by pulling back on the door’s tab and lifting upward.
2. Access for wire or cable is via two 5/8 in.diameter
snap-in shutter bushings located on the rear of the
C51’s cover.
3. Connect the C51 to a CTE–5100 thermostat and other control components as shown on the control package wiring diagram.
4. Replace wiring access door.

D. AIR FLOW SENSOR CONNECTION
The VAV controller includes an on-board flow-thru type sensor, and therefore, the length & size of pneumatic tubing (and fittings and kinks in the tubing) will affect the relationship between the airflow rate (cfm) through the air terminal and controller signal generated for that airflow rate, ie the flow curves. Our flow curves which depict VDC vs. CFM were developed in the lab with the tubing lengths as follows (no fittings):

Magnehelic Gauge to Airflow Rate Chart
This airflow chart is an example of the chart affixed to the VAV box. Each chart is specific for the type of flow sensor located in the inlet side of the VAV box. Read the differential pressure of the Magnehelic gauge, follow the line horizontally until it crosses the diagonal inlet size of box. Read straight down from this intersection to determine the flow rate.

E. ROTATION SETUP
The C51 is factory-set for proper rotation. If the rotation needs to be changed:
1. Remove the access door by pulling back on the door’s tab and lifting upward.
2. Position both jumpers in either the CW or CCW positions as needed. See the diagram.

model C51
VAV Flow Controllers Actuators analog electronic controllers

F. ACTUATOR TESTING
Test the C51 actuator’s motor operation:
1. Temporarily disconnect the thermostat reset connection at
Terminal “IN”.
2. Jumper “IN” terminal to the “16 VDC” terminal. The green
Open LED should illuminate. The shaft drive hub should be rotating the damper open (typically CW). The damper should go to full open unless the maximum limit was set at the C51, and then the damper will only go to the maximum setting. If the damper is rotating closed (typically CCW), the “Close” jumpers must be changed. Refer to the Rotation Setup section.
3. Jumper “IN” terminal to the “–” terminal. The red Close LED should illuminate. The shaft drive hub should be rotating the damper closed (typically CCW). The damper should go to full closed unless the minimum limit was set at the C51, and then the damper will only go to the minimum setting. If the damper is rotating open (typically CW), the “Close” jumpers must be changed. Refer to Rotation Setup section.
G. SYSTEM TROUBLESHOOTING
The following troubleshooting guide is directed towards single duct cooling applications, but the same concepts can be applied to other configurations.
1. Verify 24 volts AC at terminals “~” (phase) and “–” (ground).
Tolerance can be –15% to +20% (20.4 to 28.8 volts AC)
NOTE: When using the same transformer for more than one control, the phase and ground must be consistent with each device.
2. Verify 16 volts DC at terminals “(16 VDC)” and “(–)”.
Tolerance is 15.0 to 17.0 volts DC, power supply to thermostat. If not correct, disconnect the thermostat and recheck. If still incorrect, replace the C51 controller.
3. Check “Requested Flow” voltage on the “IN” and “–” terminals.
Reference the VDC vs. CFM flow curves.
4. Check “Actual Flow” voltage on terminal “OUT” and “–” for
(0–10 volts DC). The “IN” and “OUT” voltages should match
(within a reasonable tolerance). If they do not, change the setpoint all the way up or down, wait at least five minutes, and measure again. If they still do not match, check for the following:
A. There is low static pressure in the system and the design airflow rate cannot be achieved. The damper will typically be wide open when this occurs.
B. The actuator position and damper position is out of synchronization.
C. The setscrews on the actuator shaft may be slipping.
D. The VNOM potentiometer may have been changed from its factory setting. See the VNOM Range Setting section.
5. If the “Requested Flow” and “Actual Flow” match, but the reading from a flow hood over the duct outlet is substantially different, one of the following may be at fault:
A. The tubing to the controller’s flow sensor may be kinked, too long, or pulled off (fix the tubing).
B. The flow sensor in the controller may be bad (replace the controller).
6. Check box movement, damper rotation, etc.
A. Review “Requested Flow” and “Actual Flow” above to determine if unit should be satisfied (within 50 fpm) or driving open or closed.
B. If damper is not moving, verify damper is not stuck or at end of travel. Check rotation jumpers for proper position.
A-6
C. Change “Requested Flow “to drive the unit in the opposite direction. This can be accomplished by moving the setpoint sliders or the steps below.
CAUTION
Never jumper terminal “16 VDC” to terminal “–” since this would cause a short and possibly damage the power supply.
i. To manually open the box, remove wiring from terminal “IN” and jumper terminal “IN” to terminal “16 VDC”. This will tell unit to control at full airflow, the green LED should turn on, and the box should drive open (typically CW).
ii. To manually close the box, remove wir ing from terminal
“IN”, and jumper “IN” terminal to “–” terminal. This will tell unit to control at zero airflow, the red LED should be on and the box should drive closed (typically CCW).
H. CONTROLLER CALIBRATION
Minimum and Maximum Flow Limits
Minimum and maximum flow limits are typically set at the
CTE–5100 series wall thermostat. See the CTE–5100 Series thermostat reference section and applicable control package.
Anemostat does not recommend setting the flow limits at the controller, and this procedure should not be followed if the applicable control package specifically indicates “Adjustments at
Thermostat”. If required, the minimum and maximum limits can be defined by adjusting the appropriate setpoints within the C51 controller (see below) instead, but do not try to set the limits at
BOTH the controller and the thermostat (or else the limits will not reflect either the controller’s or the thermostat’s limits).
To set the airflow limits at the C51:
1. Remove the access door by pulling back on the door’s tab and lifting upward.
2. Connect a voltmeter to the meter taps (using HSO–5001 test leads).
3. Move the jumper from the NOR (normal) position (two leftmost pins) to the MIN position (two right-most pins).
4. Adjust the MIN potentiometer for the desired minimum voltage.
NOTE: MIN must be adjusted first.
5. Move the jumper to the MAX position (two center pins).
6. Adjust the MAX potentiometer to the desired maximum voltage.
7. Return the jumper to the NOR position.

VAV Flow Controllers Actuators analog electronic controllers
I. VNOM (CFM) RANGE SETTING
The C51 range is factory-calibrated with the VNOM potentiometer centered.
Leaving the VNOM at the factory setting is recom mended!
Changing the VNOM potentiometer from the factory setting will alter the calibration between the “IN” and “OUT” voltages.
However, the VNOM can be adjusted to match 0–10 volts to a specific ve locity range if desired.
NOTE: In the controller, VNOM stands for “NOMinal Volumetric flow rate.”
To set the VNOM range:
1. Remove the access door by pulling back on the door’s tab and lifting upward.
2. Supply the desired airflow rate to the “H” and “L” ports.
3. Connect a voltmeter between the “OUT” and “–” terminals and adjust the VNOM potentiometer until the voltage equals 10 volts DC.

Checkout and Calibration
The thermostat (CTE–5100 series) operates on a 16 volt DC power supply from the C51 controller and outputs a 0–10 volt
DC signal on the T(x) terminals (Direct Acting T1 and Reverse
Acting T2). See the CTE–5100 Series Thermostat Reference
Page for de tails on which ‘T’ terminals are used on each model thermostat. The applicable control package will indicate which terminals are used. There are two types of thermostat outputs
– those which can be limited by adjustment (within the range of
0-10VDC), and those which are unlimited and non-adjustable (0-
10VDC over the proportional band)
NOTE: Airflow limits are typically set at the wall thermostat, but can be set at the C51 or the CTE thermostat. If setting the min/max limits at the CTE thermostat, the C51’s
Min. dial must be set fully CCW to 0 and the Max. dial set fully CW to 100. This will ensure that the C51 will not have any effect on the limits.
1. Required tools:
1/16-inch hex/key wrench
Small flat blade (1/8-inch) screwdriver
Digital voltmeter capable of displaying a 0–10 volt DC range which will display in hundredths of a volt.
HSO–5001 test leads (optional for meter taps)
2. Remove the thermostat cover by loosening the setscrews on each side of the thermostat (see illustration). Using a 1/16inch hex key wrench, turn the setscrews clockwise until the cover is loose.
3. Check voltages:
A. Verify 16 volts DC between (+) and (–) terminals.
B. Measure “T(x)” to “–” for output voltage. Use the calibration procedures below to adjust limits if desired.
Adjust the setpoint above and below current room temperature and observe changes in appropriate “T” voltage. Remove setpoint slider stops (HFO–0027) if necessary.
B. THERMOSTAT AIR FLOW ADJUSTMENT
PROCEDURES
Basic adjustment procedures are shown for the various types of thermostats that may be used for a specific control package.
These are typical adjustment procedures which are used for most applications. However, unique control strategies may employ other functionality and these basic adjustment procedures may not apply.
Refer to Voltage vs. CFM curves to relate the voltage setting at the thermostat for the air flow rate required based on the size of the air terminal. A secondary measuring device such as a flow hood should be used to verify actual flow rates into the space. A shortfall in air quantity may be due to closed dampers, or insufficient fan static pressure required for the system.
Note: ALWAYS adjust the minimum flow limit first. To properly set the min and max flow setpoints, the ambient room temperature must be between 55-85°F.
Maximum limits will always be greater than the minimum limits
(maximum is additive to the minimum). If in doubt, turn the maximum limit fully clockwise (increase) before proceeding.
Dials rotate approximately 200° (8 to 4 o’clock). Turn clockwise to increase or counterclockwise to decrease. Do not use excessive force on the dials. They should turn freely and effortlessly. DO NOT force dial beyond the stop.
Connect voltmeter to one of the two meter taps (#HSO-5001 test lead adapter makes this easier and is available through your local Anemostat representative). There is a
HEATING (Left Side) and a
COOLING (Right Side) meter tap, so connect to the proper tap when adjustments are being made.

D. CHANGING A CTE–5100 THERMOSTAT TO A
REMOTE SENSOR
A thermostat controller with an external temperature sensor provides a means to remotely locate the tem perature sensor in the supply or return air duct or in an area where remote adjustment of the setpoint is desired.
The CTE–5100 series thermostat can be easily modified to accomplish this application. Since the CTE–5100 series thermostats have an averaging temperature input, a thermistor can be wired to this input and the thermostat’s thermistor can be removed.
The thermistor is clearly visible once the scale plate is removed, simply clip both leads underneath the thermistor to remove it. The remote thermistor is then wired to terminals
“+12 V” and to “A” (as shown in chart below).
TTE series remote temperature sensor/transmitters include a three wire sensor with “+”, “A”, and “–” connections. When the
TTE series are used as remote sensors for the CTE–5100 series, only the “+” and “A” connections are used. These two connections are to the thermistor (resistance) only (not a voltage output). The chart below illustrates the various TTE models and the appropriate terminal designations.

Thermostat analog electronic controllers
DESCRIPTION AND APPLICATION
The Anemostat CTE-5202 thermostat is a dual-setpoint, analog electronic controller with a digital LCD display for use in many new and replacement room temperature control applications. It provides two independent electronic PI (Proportional + Integral) control loops with heating and cooling setpoints. The thermostat drives two (adjustable span) 0-12 VDC analog outputs for control of external devices. The easy to understand LCD display and push but-tons enable viewing of current temperature, chang-ing of setpoints, and simple device configuration. The thermostat is typically used with Anemostat CEP/ CSP-4000 and CSP-5000 series of electronic pressure-independent VAV controllers, MEP-4002 proportional electronic actuators in pressure-dependent VAV applications, and VEB-43/46 series proportional control valves in baseboard and other heating/cooling applications. Application sequences may be se-lected for the following types of room and terminal unit control:
• Single-duct pressure-independent VAV terminals, with or without reheat and auxiliary minimum airflow (see Sequence 2 on page 3)
• Single-duct pressure-dependent VAV terminals with or without reheat (Sequence 1 for single set-point or Sequence 2 for dual setpoint and/or aux. minimum)
• Single-duct fan-powered VAV terminals with or without reheat using REE-5xxx staging modules (Sequence 1)
• Dual-duct VAV applications with independent control of heating and cooling outputs (Sequence 3)
• Proportional heating and cooling applications, such as baseboard heating and chilled beams (Sequence 1 and 3)
Common application features for morning warm-up, changeover, and unoccupied/night setback are enabled via an external temperature sensor and/or contact closure provided by a remote building auto-mation system.
NOTE: For many examples of new and retrofit applications, see the CTE-5202 Applications Guide.

NOTE: A01 is typically used to control the cooling output (primary air damper or cooling valve), and A02 is used to control the heating output (VAV reheat or heating valve).
Hot/Cold Changeover
For hot/cold changeover on Sequence 1 or 2, connect a changeover sensor to the All input. The sensor should be a Type Ill thermistor (10K ohm @ 77° F), such as
Anemostat STE-140x duct or STE-1454/1455 strap-on sensors. (An internal 10K ohm pullup resistor is provided on All .) Leave sensor off for continuous cold air mode.
Unoccupied/Standby Setback
Contact closure across All and Common initiates the unoccupied/standby setback sequence, which causes the cooling setpoint to increase and the heating set-point
(where applicable) to decrease by the amount of the
(selectable) setback offset. In Sequence 2 or 3, it would shift both the cooling setpoint and the heat-ing setpoint.
(This setback does not apply during the morning warm-up sequence.)

GENERAL INFORMATION
CSC–2000 Series Overview
The CSC–2000s are differential-pressure (dP), submaster controllers with adjustable minimum and maximum airflow settings. A master controller, typically a room thermostat, resets the CSC velocity setpoint.
CSC–2000s are available as direct acting for normally open VAV terminal units, and reverse acting for normal closed VAV terminal units. Each unit is equipped with separate adjustment knobs for minimum and maximum airflow settings. Calibrate all models using standard airflow measuring equipment.
The spring range of the actuator does not matter to the controller. However, sufficient main air is required to provide the actuator with enough force to operate the damper/linkage.
Any sequencing with other controllers, valves, or pneumaticelectric relays must be sequenced with the controller’s reset range, not the actuator’s spring range.
These controllers are typically used on single-duct applications but may be found in dual-duct applications. When working on dual-duct applications it may be necessary to work on one duct at a time while closing off the other.
The CSC–2000 series controllers are position sensitive. See the
Mounting section for the proper vertical/horizontal orientation for the different models.
CAUTION
Pneumatic devices must be supplied with clean, dry control air.
Any other medium (e.g., oil or moisture contamination) will cause the device to fail.

MOUNTING
As close to the flow sensor pickup as is feasible, fasten the mounting bracket to the mounting surface with two selfthreading screws in the two 3/16 in. (5 mm) holes. (Make sure to leave enough room to make connections.)
The CSC–2000 series are position sensitive:
• The minimum and maximum flow limits must be set
(calibrated) in the same position the controller will be mounted.
• May be mounted horizontally (preferred),with the adjustment knobs up or down, or mounted vertically (the diaphragm inside must be in a horizontal or vertical plane).
CONNECTIONS
Use 1/4 in. (6 mm) O.D. “FR” tubing for the following connections:
1. Connect the main air supply to port “M”.
2. Connect the actuator to port “B”.
3. Connect the thermostat to port “T”.
C23 Units
Use 3/8 in. O.D. “FR” tubing with a maximum length of 24 in.
to connect:
1. High pressure to port “X”.
2. Low pressure to port “Y”.
C24 Units
Use 3/8 in. O.D. “FR” tubing with a maximum length of 24 in.
to connect:
1. Low pressure to port “X”.
2. High pressure to port “Y”.
CAUTION
Pneumatic devices must be supplied with clean, dry control air.
Any other medium (e.g., oil or moisture contamination) will cause the device to fail.

ADJUSTMENTS, CALIBRATION, AND OPERATION OF
C23 CONTROLLERS
Adjustments and Calibration
1. Check that there is 0 psi at the “T” Port.
2. Use a flow hood or “tee” a Magnehelic® (or equivalent) differential pressure gauge between the controller and the dP pick-up.
3. The “LO” flow setting limit (center knob) must be set first.
Temporarily adjust the thermostat for a branch pressure lower than the 8 psig reset start point (minimum cooling); typically 6 psig or less is best. Removing the thermostat branch line would be another acceptable method. Adjust the
“LO” knob (center knob) clockwise to increase or counterclockwise to decrease dP limit. Normally one-half turn will cause a 0.1 dP change. Allow for reaction time.
Depending on actuator size and position, timing will vary. To position an actuator/damper from closed to open may take several minutes.
NOTE: If the “LO” flow setting limit must be set at“0” (zero minimum), do not turn the “LO” knob fully counterclockwise. The knob will adjust three to four full turns after a zero minimum is reached. Turning the “LO” knob fully counterclockwise will result in a negative reset condition. This means that when the controller is beginning to reset at 8 psig from the thermostat, it must first overcome the negative adjustment and will not begin to reset until a higher thermostat reset pressure is reached. This negative reset will also reduce the effective range of the controller by reducing the high end and narrowing the reset span. If a zero minimum is required, adjust the “LO” knob until the controller just begins to crack the damper open, then back-off one-fourth turn and verify zero airflow.
4. The “HI” flow setting limit (outer knob) must beset after the
“LO”. Temporarily adjust the thermostat for a branch pressure higher than the 13 psig reset stop point (maximum cooling); typically 17 psig or greater is best. Removing the thermostat branch line and teeing-in to the main air line would be another acceptable method. Adjust the “HI” knob
(outer knob) clockwise to increase or counterclockwise to decrease dP limit. Nominally one-half turn will cause a 0.1 dP change. Allow for reaction time.
5. Recheck the “LO” and the “HI” settings at least twice, verify settings, and fine tune each time if necessary. This procedure will remove internal component tensions and confirm settings.
6. Reconnect the thermostat branch line if necessary, and adjust the thermostat to the desired room temperature setpoint.
NOTE: The“HI” adjustment limits the travel of the reset mechanism. Therefore, the reset span will be less than
5 psig, the upper limit being less than 13 psig.
NOTE: Always make adjustments in the same plane/orientation as the one in which the unit will operate.
NOTE: No routine maintenance is required. Each component is designed and manufactured for reliability and performance. Careful installation and use will ensure long-term dependability.
NOTE: For information about C24 controllers see the
Adjustments, Calibration, and Operation of C24
Controllers section.

model C23 pneumatic controllers
PRESSURE INDEPENDENT OPERATION
Differential pressure is sensed via a dP pickup mounted upstream of the damper (VAV terminal inlet). The dP pickup is a dual pressure pickup sensing both high pressure and low pressure. The high pressure is connected to the “X” port and the low pressure is connected to the “Y” port. These two pressures are compared across the static diaphragm, which takes a position relative to the difference of the two pressures, the force of the LO limit adjustment spring in the upper chamber, and the force of the HI limit adjustment spring in the lower chamber.
Turning the “LO” knob clockwise (to increase) relaxes the LO limit adjustment spring, placing a lesser downward force on the diaphragm, reducing the pressure at the “B” port, and increasing airflow through the VAV terminal. Turning the “HI” knob adjustment spring counterclockwise positions the HI limit stop downward, limiting the travel of the piston cup, limiting the amount of reset, and setting the maximum airflow through the
VAV terminal.
When the “HI” knob is turned fully counterclockwise, the HI limit will equal the LO limit, and the controller will function as a constant volume controller.
An increase in airflow is sensed via the increase in dP across the static diaphragm, positioning the static diaphragm closer to the nozzle, increasing the “B” port pressure to the actuator, and decreasing airflow until the static diaphragm comes into balance at the desired dP setpoint.
A decrease in airflow is sensed via the decrease in dP across the static diaphragm, positioning the static diaphragm away from the nozzle, decreasing the “B” port pressure to the actuator, and increasing airflow until the static diaphragm comes into balance at the desired dP setpoint.
RESET OPERATION
With sufficient airflow and a thermostat signal connected to the
“T” port of less than 8 psig, the controller will position the actuator to regulate airflow at the LO limit setting. In this state, the static diaphragm is balanced over the nozzle through the forces of the opposing springs and forces of the high and low pressures.
When the thermostat signal increases above 8 psig, the piston cup will begin to position the reset lever upward, increasing the force of the HI limit spring, positioning the static diaphragm away from the nozzle, opening the damper for greater airflow, and requiring a higher dP to rebalance the static diaphragm.
The dP setpoint of the controller has been reset upwards with the increasing thermostat signal. The stroke of the piston cup is limited via the HI limit knob. Lowering the HI limit will reduce the top end of the reset span, narrowing the reset span. At each new dP setpoint, as dictated by the thermostat signal, the static diaphragm will again balance.

2. Use a flow hood or “tee” a Magnehelic® (or equivalent) differential pressure gauge between the controller and the dP pick-up.
3. The “HI” flow setting limit (center knob) must be set first.
Temporarily adjust the thermostat for a branch pressure lower than the 3 psig reset start point (maximum cooling); typically 1 psig or less is best. Removing the thermostat branch line would be another acceptable method. Adjust the
“HI” knob (center knob) counterclockwise to increase or clockwise to decrease dP limit. Normally one-half turn will cause a 0.1 dP change. Allow for reaction time. Depending on actuator size and position, timing will vary. To position an actuator/damper from closed to open may take several minutes.
4. The “LO” flow setting limit must be set after the“HI”.
Temporarily adjust the thermostat for a branch pressure higher than the 8 psig reset stop point (minimum cooling); typically 12 psig or greater is best. Removing the thermostat branch line and teeing-in to the main air line would be another acceptable method. Adjust the “LO” knob (outside knob) counterclockwise to increase or clockwise to decrease dP limit. Normally one-half turn will cause a 0.1 dP change.
Allow for reaction time.
5. Recheck the “HI” and the “LO” settings at least twice, verify settings, and fine tune each time if necessary. This procedure will remove internal component tensions and confirm settings.
6. Reconnect the thermostat branch line if necessary, and adjust the thermostat to the desired room temperature setpoint.
NOTE: The“LO” adjustment limits the travel of the reset mechanism. Therefore, the reset span will be less than

NOTE: Always make adjustments in the same plane/orientation as the one in which the unit will operate.
NOTE: No routine maintenance is required. Each component is designed and manufactured for reliability and performance. Careful installation and use will ensure long-term dependability.
PRESSURE INDEPENDENT OPERATION
Differential pressure is sensed via a dP pickup mounted upstream of the damper (VAV terminal inlet). The dP pickup is a dual pressure pickup sensing both high pressure and low pressure. The low pressure is connected to the “X” port and the high pressure is connected to the “Y” port. These two pressures are compared across the static diaphragm, which takes a position relative to the difference of the two pressures, the force of the HI limit adjustment spring in the upper chamber, and the force of the LO limit adjustment spring in the lower chamber.
Turning the “HI” knob counterclockwise (to increase) compresses the HI limit adjustment spring, placing a greater downward force on the diaphragm, increasing the pressure at the “B” port, and increasing air through the VAV terminal. Turning the “LO” knob adjustment spring counterclockwise positions the LO limit stop downward, limiting the travel of the piston cup, limiting the amount of reset, and setting the minimum airflow through the
VAV terminal.
When the “LO” knob is turned fully counterclockwise, the LO limit will equal the HI limit, and the controller will function as a constant volume controller.
An increase in airflow is sensed via the increase in dP across the static diaphragm, positioning the static diaphragm away from the nozzle, decreasing the “B” port pressure to the actuator, and decreasing airflow until the static diaphragm comes into balance at the desired dP setpoint.
A decrease in airflow is sensed via the decrease in dP across the static diaphragm, positioning the static diaphragm closer to the nozzle, increasing the “B” port pressure to the actuator, and increasing airflow until the static diaphragm comes into balance at the desired dP setpoint. 3.

model C24
RESET OPERATION
With sufficient airflow and a thermostat signal connected to the
“T” port of less than 3 psig, the controller will position the actuator to regulate airflow at the HI limit setting. In this state, the static diaphragm is balanced over the nozzle through the forces of the opposing springs and forces of the high and low pressures.
When the thermostat signal increases above 3 psig, the piston cup will begin to position the reset lever upward, increasing the force of the LO limit spring, positioning the static diaphragm away from the nozzle, closing the damper for less airflow, and requiring a lower dP to rebalance the static diaphragm.
The dP setpoint of the controller has been reset downwards with the increasing thermostat signal. The stroke of the piston cup is limited via the LO limit knob. Raising the LO limit will reduce the top end of the reset span, narrowing the reset span.
At each new dP setpoint, as dictated by the thermostat signal, the static diaphragm will again balance.

GENERAL INFORMATION
C31 Series Overview
These C31 series reset volume controllers are designed for use on heating or cooling systems with (normally open or normally closed) VAV terminal units and (direct or reverse acting) thermostat.
They are sub-master air velocity controllers. Each is equipped with separate adjustment knobs for minimum and maximum airflow setpoints. Models are available with various reset start points. A master controller, typically a room thermostat, resets the CSC between the minimum and maximum velocity setpoints.
The universal design of the C31 series is intended for new or replacement applications that call for direct or reverse acting reset on normally open or normally closed VAV terminal units.
Note: These controllers are used on single and dual duct applications. When working on dual duct applications, it may be necessary to work on one duct at a time.
Note: Any sequencing with other controllers, valves, or pneumatic-electric relays must be done with the controller’s reset range, NOT the actuator’s spring range.
Mounting
The C31 series are position sensitive. They must be mounted and calibrated in either the horizontal or vertical plane.
1. As near to the flow sensor pickup as is feasible, connect the mounting bracket to the mounting surface with two selfthreading screws in the two 3/16" (5 mm) mounting holes.
Be sure to leave enough room to make connections.
2. Insert the controller, face down, up, right or left. The controller must be installed and adjusted in the same plane or readjustment will be necessary.

CONNECTIONS
Use 1/4" (5 mm) O.D. “FR” tubing on the following push-on fittings:
1. Connect the clean, dry, oil-free main air supply to Port “M”
(15 to 30 psig).
2. Connect the damper actuator to Port “B”.
3. Connect the thermostat output to Port “T”.
4. Connect the high pressure tap on the airflow sensor to Port “H”.
5. Connect the low pressure tap on the airflow sensor to Port “L”.
6. Check for proper connections. Make sure all tubes are snug on their fittings. If loose, trim the end of the tubing and reconnect it to ensure there are no leaks.
NOTE: Over time, the tube may stretch or develop microcracks.
Trim the end of tube back to undamaged material and reconnect. Replace the tubing if it is brittle or discolored.
NOTE: You can easily test for leaks with a squeeze bulb to ensure there are no leaks at the actuator diaphragm or fittings.
7. Use a flow hood or “tee” a Magnehelic ® (or equivalent) differential pressure gauge between the controller and the dP pick-up to determine airflow.
CAUTION
Pneumatic devices must be supplied with clean, dry control air.
Any other medium (e.g., oil or moisture contamination) will cause the device to fail.

ADJUSTMENTS AND CALIBRATION
Damper Action
The damper action is factory-set at Normally Open (N.O.). To change to Normally Closed (N.C.), perform the following steps:
1. Loosen the damper selection screw.
2. Turn the selection dial clockwise until the “NC” arrow aligns with the “DAMPER” arrow.
NOTE: Accuracy in the alignment of the arrows is very important. Make this adjustment as exact as possible.
3. Tighten the selection screw. Be sure the screw is tight (2 to
4 in-lbs. of torque), but if over-tightened, the plastic will strip out.
Determining the Type of Reset
The following table sows when Direct Reset or Reverse Reset is required. Determine the reset type based on the temperature of the primary air entering the VAV box and whether the thermostat in the space is direct or reverse acting.

Adjusting Minimums and Maximums
When adjusting the minimum and maximum airflow settings, the output responds slowly to changes in the setpoint. Wait for the flow rate to stabilize after making an adjustment (usually 20 to
30 seconds) before making further adjustments. Also, if the damper position is all the way closed or open when starting this step, turn the adjustment one full turn, and then wait 20 to 30 seconds for a change in the flow reading of the Magnehelic gauge. If no change occurs after this time, repeat until the flow rate changes.

NOTE: The direct reset illustration above assumes no relays are connected between the thermostat and the “T” port.
For Direct Reset (DA thermostat for cooling or RA thermostat for heating), perform the following steps:
1. Adjust the thermostat to a setting that will cause the output pressure to be as high as possible (15 psi or more). This can be done in the following manner: a. For Direct Acting thermostats, lower the setting to the lowest possible setting.
b. For Reverse Acting thermostats, raise the setting to the highest possible setting.
2. On the C31, disconnect the “T” port. Temporarily plug the tubing. (Do NOT plug the port.)
3. Adjust the LO STAT dP (center dial) one adjustment (1/4 to
1/2 knob rotation) at a time until the desired Minimum airflow is read at the Magnehelic gauge and is stable.
NOTE: If the LO STAT dP Limit must be set at “0” (zero minimum), do not turn the LO STAT dP knob fully clockwise. The knob will adjust one and one-half turns after a zero minimum is reached. Turning the LO STAT dP knob fully clockwise will result in a negative reset condition. This means that when the controller begins to reset at the reset start point it must first overcome the negative adjustment and will not begin to reset from “0” until a higher thermostat reset pressure is reached. This negative reset will also reduce the effective range of the controller by reducing the low end reset; narrowing the reset span. If a zero minimum is required, adjust the LO
STAT dP knob until the controller just begins to crack the damper open, then back-off one-quarter turn and verify zero airflow. (This is typically 2-1/2 knob rotations counterclockwise from the fully clockwise position.)
4. Reconnect the thermostat tubing to the “T” port. This will put
15 PSI or more on the “T” port.
5. Adjust the HI STAT dP (dial on right) one adjustment (1/4 to
1/2 knob rotation) at a time until the desired Maximum airflow is read at the Magnehelic gauge and is stable.
6. Repeat Steps 2 through 5 to verify the settings to be correct and fine tune if necessary.

NOTE: The reverse reset illustration above assumes no relays are connected between the thermostat and “T” port.
For Reverse Reset (RA thermostat for cooling or DA thermostat for heating), perform the following steps:
1. Adjust the thermostat to a setting that will cause the output pressure to be as high as possible (15 psi or more). This can be done in the following manner: a. For Direct Acting thermostats, lower the setting to the lowest possible setting.
b. For Reverse Acting thermostats, raise the setting to the highest possible setting.
2. On the C31, disconnect the “T” port and leave it open.
Temporarily plug the open tubing.
3. Adjust the LO STAT dP (center dial) one adjustment (1/4 to
1/2 knob rotation) at a time until the desired MAximum airflow is read at the Magnehelic gauge and is stable.
4. Reconnect the thermostat tubing to the “T” port. This will put
15 PSI or more on the “T” port.
5. Adjust the HI STAT dP (dial on the right) one adjustment
(1/4 to 1/2 knob rotation) at a time until the desired
Minimum airflow is read at the Magnehelic gauge and is stable.
NOTE: If the HI STAT dP Limit must be set at”0” (zero minimum), do not turn the HI STAT dP knob fully clockwise. The knob will adjust past where a zero minimum is reached. Turning the HI STAT dP knob fully clockwise will result in a negative reset condition. This means that the controller will get to zero before going through the whole reset span. If a zero minimum is required, adjust the HI STAT dP knob until the controller just begins to crack the damper open, then back off slightly and verify zero airflow.
6. Repeat Steps 2 through 5 to verify the settings to be correct and fine tune if necessary.
Reset Start Point
The reset start point is the pressure from the thermostat at which the controller begins to reset from LO STAT to the HI
STAT setting.
If a reset start point is needed other than the default setting, all models are field adjustable between 0 and 10 psig. (If the reset start point is changed, the reset span may need to be adjusted as well.) To adjust the reset start point, carry out the following steps:
1. Put the thermostat pressure at the desired start point pressure (e.g., 3 psig).
2. Remove rubber plug at the “G” port and read pressure at “G” with a 0 - 30 psi gauge (requires 5/32" O.D. tubing).
3. With a small flat-blade screwdriver, adjust (counterclockwise to increase; clockwise to decrease) the reset start point control (at the top of the controller) until the pressure read at “G” port is just beginning to move off zero (0) psig.
NOTE: If the controller does not respond correctly after all adjustments have been made, it may be necessary to correct the reset span adjustment.

Reset Span
The reset span is the thermostat’s effective reset range for the controller. A reset span 5 psig means that it will take a 5 psig pressure change measured from the reset start point to reset the flow rate of the VAV box.
Reset Span (5 psig)
Max. Airflow
Reset Start Point (8 psig)
Min. Airflow
3 psig 8 psig
Thermostat Pressure
13 psig
NOTE: Reset span is the pressure change at “T” above the reset start point that causes the flow setpoint to move from one extreme to the other. In a direct reset application, the flow setpoint will change from minimum to maximum flow above the start point. In a reverse reset application, the reset will change from maximum to minimum flow above the start point.
If necessary, the reset span can be adjusted (between 0 and 10 psig). If the reset span is changed, the minimum and maximum flows may need to be readjusted.
To adjust the reset span to another value, perform the following steps:
1. Adjust the thermostat to a higher pressure, beyond working range (20 psig is best).
2. Attach a pressure gauge to the “G” port (requires 5/32"
O.D. tubing).
3. With a small flat-blade screwdriver, adjust (counterclockwise to increase; clockwise to decrease) the reset span control (at the bottom of the controller) until pressure at the “G” port equals the desired reset span pressure. Pressure read at this port will always be between 0 and the active reset span setting.
Troubleshooting
The C31 is position sensitive. Be sure to mount the controller with the correct orientation. See the Mounting section. If the controller is calibrated in a position other than the final mounting position, the calibration (minimum and maximum flow limits) will be off.
The spring range of the actuator does not matter. However, sufficient main air is required to provide the actuator with enough force to operate the damper/linkage. Also there can be no leaks in the actuator since even small leaks can cause the actuator to not stroke. You can easily test for leaks with a squeeze bulb to ensure there are no leaks at the actuator diaphragm or fittings.
Any sequencing with other controllers, valves, or pneumaticelectric relays must be sequenced with the controller’s reset range, not the actuator’s spring range.
These controllers are typically used on single-duct applications but may be found in dual-duct applications. When working on dual-duct applications it may be necessary to work on one duct at a time.
Maintenance
No routine maintenance is required. Each component is designed and manufactured for reliability and performance.
Careful installation and use will ensure long-term dependability.
CAUTION
Pneumatic devices must be supplied with clean, dry control air.
Any other medium (e.g., oil or moisture contamination) will result in the device’s eventual failure.
B-14
model C31 pneumatic controllers
Pressure Independent Operation Principles
Differential pressure is sensed via a dP pick-up mounted ahead of the damper (VAV terminal inlet). The dP pick-up is a dual pressure pick-up sensing both high and low pressures. The high pressure is connected to the “H” port and the low pressure is connected to the “L” port. These two pressures are compared across the diaphragm. (No air is transferred between the “H” and “L” port.) The diaphragm positions a reset lever relative to the pressure difference between the force of the LO STAT dP spring and the position of the HI STAT dP setting.
Turning the LO STAT dP knob counterclockwise (to increase) repositions the reset lever away from the normally open nozzle and towards the normally closed nozzle. LO STAT dP adjustments must be done with the “T” port pressure being less than the RESET START pressure.
• “NO” DAMPER selection (normally open dampers) – Turning the LO STAT dP knob counterclockwise (increase) will reposition the reset lever away from the normally open nozzle, decreasing the “B” port pressure and increasing airflow through the terminal unit.
• “NC” DAMPER selection (normally closed dampers) – turning the LO STAT dP knob counterclockwise (increase) will reposition the reset lever towards the normally closed nozzle, increasing the “B” port pressure and increasing the airflow through the terminal unit.
Turning the HI STAT dP knob counterclockwise (to increase) repositions the fulcrum towards the nozzles. HI STAT dP adjustments must be done with the “T” port pressure being greater than the RESET START pressure plus the RESET SPAN pressure.

C31 SERIES
RESET VOLUME CONTROLLERS
Description and Application
These C31 series reset volume controllers are designed for use on heating or cooling systems with (normally open or normally closed) VAV terminal units and (direct or reverse acting) thermostats.
They are sub-master air velocity controllers. Each is equipped with separate adjustment knobs for minimum and maximum airflow setpoints. Models are available with various reset start points. A master controller, typically a room thermostat, resets the C31 between the minimum and maximum velocity setpoints.
The universal design of the C31 series is intended for new or replacement applications that call for direct or reverse acting reset on normally open or normally closed VAV terminal units.

INSTALLING THE CONTROLLER
This section provides important instructions and guidelines for installing the controller. Carefully review this information prior to attempting installation.
Set the rotation limits
Note
Before mounting the controller, set the rotational limits with two supplied stop pins. These settings limit the shaft rotation in the clockwise (CW) and counterclockwise (CCW) directions. (See Illustration 2-1.)
Caution
Before setting the rotation limits on the controller, refer to the damper position specifications in the VAV control box to which the controller will be attached. Setting rotation limits that do not match the VAV damper may result in improper operation or equipment damage.

To set the rotational limits:
1. Turn the controller over so you have access to the back.
2. Locate the two stop pins installed in the back of the unit.
(You will find one pin in a CCW setting and one in a CW setting.)
3. Identify the limits for the VAV damper.
The maximum amount of shaft rotation is 90°. Placing a stop pin in both 90° slots allows the actuator the full 90° of travel.
Placing a stop pin in any other slot restricts actuator motion in the indicated direction (CW or CCW). Refer to Illustration 2-2 for pin placement and travel. The first number represents the
CCW pin and the second the CW pin (CCW/CW).

CONNECTING INPUTS
The ABC-7003 controller has three universal inputs. Each input can be configured to receive either analog or digital signals. By using the pull-up resistors, either passive or active devices may be connected to the inputs.
Note
Control Basic programs assigns input 1 (I1) to the space temperature sensor input. If the programs are not used or are modified, input 1 is available for other use.
Pull–up resistors
For passive input signals, such as thermistors or switch contacts, use a pull-up resistor. For thermistors and most other applications set the switch to the On position. See Illustration
2-5 for the pull-up switch location.
CONNECTING OUTPUTS
ABC-7001 provides three universal outputs. Returns are connected to the GND terminal next to output O3. (Refer to
Illustration 2-6)
Output terminals
Illustration 2-6a ABC-7001 Output terminals
The ABC-7003 includes one single-stage triac, one relay and one universal output. The triac output is rated for 24 volt, 1 ampere loads, switch on zero crossing and are optically isolated.
The relay contacts are rated for 24-volts at 2 amperes.
Pull-up resistors
Off On
Illustration 2-5 Pull-up resistors
4–20 mA inputs
To use a 4–20 current loop input, connect a 250 ohm resistor from an input to ground. The resistor will convert the current input to a voltage which can be read by the controller analog-todigital converter. Set the pull-up switch to the Off position.
Ground terminals
Input ground terminals are located next to the input terminals.
Up to two wires, size 14–22 AWG, can be clamped into each ground terminal. If more than two wires must be joined at a common point, use an external terminal strip to accommodate the additional wires.
Pulse inputs
Connect pulse inputs under the following conditions:
• If the pulse input is a passive input such as switch contacts, then place the input pull-up in the On position.
• If the pulse is an active voltage (up to a maximum of +5 volts
DC), then place the input pull-up switch in the Off position.
GND
Output terminals
Illustration 2-6b ABC-7003 Output terminals
Caution
When connecting loads to the triac or relay output, use only the terminal marked RTN associated with the triac or relay for the 24-volt circuit.
Output 1 This output is a universal output that can be programmed as either an analog or digital object. Use the GND termination the input connector block for the ground.
Output 2 This is a triac which can be programmed to switch valve actuators or 24-volt reheat circuits.
Output 3 This normally open relay contact is typically programmed to control a 24-volt fan starting circuit.
Output 4 Output 4 is internally connected to the actuator motor.
CONNECTING TO A NETSENSOR
The Network RJ–12 connector provides a connection port to a
NetSensor model ABC-1161 or ABC-1181. Link the controller to a NetSensor with an approved cable up to 75 feet long. See the installation guide supplied with the NetSensor for complete
NetSensor installation instructions.

CONNECTING TO AN MS/TP NETWORK
Illustration 2-8 MS/TP network connection
Connections and wiring
Use the following principles when connecting a controller to an
MS/TP network:
• Connect no more than 128 addressable BACnet devices to one MS/TP network. The devices can be any mix of controllers or routers.
• To prevent network traffic bottlenecks, limit the MS/TP network size to 60 controllers.
• Use 18 gauge, twisted pair, shielded cable with capacitance of no more than 50 picofarads per foot for all network wiring.
Belden cable model #82760 meets the cable requirements.
• Connect the -A terminal in parallel with all other - terminals.
• Connect the +B terminal in parallel with all other + terminals.
• Connect the shields of the cable together at each controller.
For BACnet controllers use the S terminal.
• Connect the shield to an earth ground at one end only.
• Use a ABC–5575 repeater between every 32 MS/TP devices or if the cable length will exceed 4000 feet (1220 meters).
Use no more than seven repeaters per MS/TP network.
• Place a ABC–5567 surge suppressor in the cable where it exits a building.
See Application Note, Planning BACnet Networks for additional information about installing controllers.
Note
The MS/TP terminals are labeled -A,+B and S. The S terminal is provided as a connecting point for the shield.
The terminal is not connected to the ground of the controller. When connecting to controllers from other manufacturers, verify the shield connection is not connected to ground.
End of line termination switches
The controllers on the physical ends of the EIA-485 wiring segment must have end-of-line termination installed for proper network operation. Set the end-of-line termination to On using the EOL switches.
Set end-of-line termination to
On in these controllers only.

CONNECTING AN AIRFLOW SENSOR
An airflow sensor is incorporated as one of the inputs to the controller. Remove the plugs and connect the tubing from the pitot assembly to the airflow sensor inputs above the drive hub.
(See Illustration 2-12.). The airflow sensor is programmed as input 4.
Airflow sensor
Illustration 2-12 Airflow sensor inputs
Note
Mount the controller close enough to the pitot tubes to keep the tubing length to be less than 24 inches between the controller’s inputs and the tubes.
CONNECTING POWER
The controllers require an external, 24 volt, AC power source.
Use the following guidelines when choosing and wiring transformers.
• Use a Class–2 transformer of the appropriate size to supply power to the controllers. Anemostat recommends powering only one controller from each transformer.
• When installing a controller in a system with other controllers, you may power multiple controllers with a single transformer as long as the total power drawn from the transformer does not exceed its rating and phasing is correct.
• If several controllers are mounted in the same cabinet, you can share a transformer between them provided the transformer does not exceed 100 VA or other regulatory requirements.
• Do not run 24 volt, AC power from within an enclosure to external controllers.
Connect the 24 volt AC power supply to the power terminal block on the lower right side of the controller near the power jumper. Connect the ground side of the transformer to the – or
GND terminal and the AC phase to the ~(phase) terminal. Power is applied to the controller when the transformer is plugged in and the power jumper is in place.

Error conditions for the LEDs
The two isolation bulbs, located next to the network switch, serve three functions:
• Removing the lamps opens the EIA-485 circuit and isolates the controller from the network.
• If one or both lamps are lit, it indicates the network is improperly phased. This means that the ground potential of the controller is not the same as other controllers on the network.
• If the voltage or current on the network exceeds safe levels, the lamps operate as fuses and may protect the controller from damage.

RESTORING FACTORY SETTINGS
If the controller appears to be operating incorrectly, or is not responding to commands, you may need to reset the controller.
Remove the cover and locate the red restart button.
To perform a reset or restart, locate the red restart pushbutton and then—in order—use one of the following procedures.
1. A warm start is the option least disruptive to the network and should be tried first.
2. If problems persist, then try a cold start.
3.If the problems continues, restoring the controller to factory settings may be required.
Caution
Read all of the information in this section before proceeding!
Note
Momentarily pushing the red reset button while the controller remains powered will have no effect on the controller.
Performing a warm start
A warm start changes the controller as follows:
• Restarts the controller’s Control Basic programs.
• Leaves object values, configuration, and programming intact.
Caution
Returning object values to their relinquished defaults during a cold start may abruptly turn connected equipment on or off.
To prevent equipment damage, turn connected equipment off or temporarily remove the output terminal blocks from the controller before performing a warm start.
To perform a cold start:
1. While the controller is powered, press and hold the restart button.
2. Remove the power jumper.
3. Release the red button before replacing the power jumper.
Note
A cold start performed by this method is the same as performing a cold start with BACkstage or from
TotalControl Design Studio.
Restoring to factory settings
Restoring a controller to factory settings changes the controller as follows:
• Removes all programming.
• Removes all configuration settings.
• Restores the controller to factory default settings.
Caution
In the unlikely event that the checksum test in RAM fails during the warm start, the controller will automatically perform a cold start. During a cold start, controller outputs may abruptly turn connected equipment on and off. To prevent equipment damage, turn connected equipment off or temporarily remove the output terminal blocks from the controller before performing a warm start.
Do either of the following to perform a warm start:
• Reinitialize the controller with either BACkstage or TotalControl
Design Studio.
• Remove the power jumper for a few seconds and then replace it.
Performing a cold start
Performing a cold start changes the controller as follows:
• Restarts the controller programs.
• Returns all object states to their initial factory settings until the controller programs update them.
• Leaves configuration and programming intact.
Caution
Resetting the controller erases all configuration and programming. After resetting to factory settings, you must configure and program the controller to establish normal communications and operation.
To reset the controller to factory settings.
1. If possible, use BACkstage or TotalControl Design Studio to backup the controller.
2. Remove the power jumper.
3. Press and hold the red restart button.
4. Replace the power jumper while continuing to hold the restart button.
5. Restore configuration and programming with BACkstage or
TotalControl Design Studio.

BALANCING VAV BOXES
WITH ABC-1161A/1181A NETSENSOR
This application note describes a method using the NetSensor to balance air flow using a flow hood, the NetSensor as a service tool and the balancer override program which is included in Anemostat BACnet VAV controllers.
Program 4 in a BACnet preprogrammed VAV controller is a balancer override routine. By enabling this program (toggling
BV29) the VAV controller is forced to control at either minimum flow or maximum flow. This is used to simplify the VAV box balancing procedure.
This reference includes the following:
1. Purpose & Overview
2. BACkstage Configuration
3. NetSensor Detail
4. Balancer Instruction Sheet
Overview
Anemostat VAV controllers are pre-programmed with NetSensor function keys defined to turn the NetSensor into a simple balancing tool. With this feature, a balance technician can:
• Adjust setpoints for Minimum and Maximum air flow (CFM).
• Enter volume conversion factors.
• View air flow (CFM) readings.
• When necessary, establish sensor correction factors
(flow correction).
Related materials
In addition to the material presented in this application note, review and have available the following reference materials:
• Installation and operation guides for the applicable ABC VAV controllers.
• BACkstage Reference Guide.
• System plans with VAV box locations, VAV box sizes and flow values.
Additional equipment
The air flow balancing method described in this application note requires the following equipment:
• Flow hood or other accurate tool to measure air flow.
• NetSensor and cable for installations that use a temperature sensor instead of a NetSensor.

If a Space Sensor is used instead of NetSensor for controlling the space temperature at the VAV box, then a NetSensor and cable can be used to plug into the controller to balance that individual VAV box.
Note: When the Balancer Override routine takes control over the standard temperature control routine, accurate space temperature control may not be maintained. You may want to repeat the previous step to turn the balancing routine off to return control to the normal temperature sequence. Not to worry if you forget to turn off the balancer routine it will be canceled automatically after 30 minutes.
Balance Method
The following is a procedure for balancing a VAV box using the
NetSensor. Other methods may be used just as effectively.
Always remember that there is up to 15 seconds between updates of the NetSensor. Modifications at the NetSensor will not take effect at the controller until an update has occurred.
Follow these steps after plugging the NetSensor into the controller. The display should show a valid space temperature.
Maximum Flow Balancing
1. Determine the flow units desired and the box size.
2. Button 4: Enter the size (area) of the VAV box from Table A.
This value is known as the “Volume Conversion Factor” and converts feet per minute (ft/min) into the desired units. The default value is 1.0 if the controller has NOT been programmed by Anemostat.
3. Button 5: Enter or verify minimum flow CFM setpoint.
4. Button 7: Enter or verify maximum flow CFM setpoint.
5. Press buttons 5 and 7 together and then press the up arrow button to turn “ON” the Balancing routine.
6. Button 2: Enter a 1 or greater. This will drive the box to the maximum CFM setpoint value as set in button 7. Wait (may take up to 5 minutes) for the value at button 3 to settle in at or near maximum CFM setpoint.
7. Measure with flow hood or other measurement device and add up the flow from each supply outlet to get the total supplied air at maximum. Differences between the displayed flow reading and field measurements may be due to sensor mounting location or turbulence. If the readings differ greatly, the flow reading can be adjusted by placing a multiplier in button 6.
8. Button 6: Enter the sensor correction factor. This value is a calculated multiplier to adjust the CFM reading at button 3 to match the actual CFM measured by the Balancer. See formula. B# = Button, Actual CFM (Balancer) / B3 (CFM reading) x B6 (Current sensor correction factor) = B6
(new sensor correction factor)
9. Repeat step 7. If the values are still too far apart then repeat step 8 and then check values again.
Minimum Flow Balancing
1. Set button 2 to 0 or less; This will drive the box to the minimum CFM setpoint value as set in button 7. Wait (may take up to 5 minutes) for the value at button 3 to settle in at or near minimum CFM setpoint.
2. Measure with flow hood or other measurement device and add the flow from each supply outlet to get the total supplied air at minimum.
3. If the readings are to far apart then change the minimum
CFM setpoint on button 5 to compensate for the error. Note: do not change the Sensor Correction Factor (B6) to correct for errors or the maximum flow balancing will be affected.
4. Repeat step 2. If the values are still too far apart then repeat step 8 then check values again.
Halting the Balance Routine
Press buttons 5 and 7 together and then press the down arrow button to turn “OFF” the Balancing routine. Wait approximately
10 seconds for the NetSensor to send the change to the device before disconnecting the NetSensor and moving to the next VAV box.
Note: not to worry if you forget to turn off the balance routine the program will automatically shut off after 30 minutes.

DESCRIPTION
The SimplyVAV series of controllers are an easy and unique approach to operating a wide variety of VAV terminal units. The integrated actuators, internal airflow sensors, and wide variety of application programs make these BACnet Application Specific controllers ideal for either new or retrofit installations.
Easy to install Just mount the controller, wire it to a 24 volt transformer, and then connect airflow and temperature sensors. A SimplyVAV controller automatically detects sensors as they are connected without special programming or software tools.
Simple, menu driven setup The controllers feature simple, menu driven setup choices. No special programming skills or software tools are required to choose applications, enter setpoints, set network addressing, and balance airflow. All options can be set by using only an STE-8001 sensor which can be installed as the permanent room sensor or temporarily connected as a technician’s service tool.
New or retrofit application The SimplyVAV controllers are ideal for new installations or upgrades of older, less efficient controller.
• Staged, modulated, floating, or time proportional reheat
• Series or parallel fan control
• Single or dual duct application
Native BACnet All models are BACnet Application Specific
Controllers that are ready to connect to aBACnet MS/TP network. Device instance, MAC address, and baud rate are set from an STE-8001 without special software.
Easy system integration For SimplyVAV installations that are part of a BACnet building automation system, the controllers provide system diagnostic indicators. Through the MS/TP network, the controllers signal demands for higher static duct pressure, cooler or warmer supply air, and when to start air handler units.
