FanMaster Overview
Chapter 1
FanMaster Description
FanMaster provides a means for improving the energy efficiency of
Constant Air Volume HVAC units. Constant Air Volume HVAC units
typically draw in room air and mix it with a small amount of outside air.
This mixed air is forced by a fan through heating and/or cooling elements to
provide supply air back to the room at a temperature that makes up for
heating or cooling lost to the surrounding environment. This maintains
comfortable conditions for the building’s occupants and contents.
FanMaster improves the efficiency of a basic HVAC unit by providing the
following two additional control features:
• FanMaster replaces a fixed speed fan motor starter with a Variable Speed
AC Drive which allows the fan speed to adjust to the actual HVAC
heating and cooling loads. The Law of Affinity states that the energy
required to operate a fan decreases by the cube of the actual speed
reduction. For example, a fan running at 80% of its maximum speed
requires about 50% of the energy needed to run the fan at full speed.
And, a fan running at 50% of its maximum speed requires only about
13% of the energy needed to run the fan at full speed. FanMaster’s ability
to monitor the HVAC operation and adjust the fan speed to the required
value provides considerable opportunity for savings.
• FanMaster regulates the amount of outside air drawn into the HVAC unit
for the purpose of ventilation by monitoring the actual Carbon Dioxide
(CO
) level in the serviced space. This feature, known as Demand
2
Ventilation, maintains air quality while reducing the cost of heating or
cooling the outside air by reducing its volume.
The typical Constant Air Volume HVAC unit selected by the building's
original designer provides adequate heating, cooling, and ventilation for
worst-case conditions. The heating and cooling capacity are selected for the
coldest and hottest days anticipated and the ventilation capacity is designed
for maximum human occupancy. Since the weather is seldom at the
extremes in most locations and buildings are often occupied at less than full
capacity, FanMaster provides a savings opportunity by reducing the fan
speed and ventilation used by the HVAC unit when they are not required. In
addition, when the weather extremes do require maximum heating or
cooling or the CO
FanMaster returns the fan to its original full speed and ventilation to the
original designed value until conditions are such that it can once again
reduce the fan speed and amount of outside air ventilation.
FanMaster has been designed for installation into an existing HVAC system
with minimal interface with the existing controls. FanMaster does not
replace or interfere with the existing controls which continue to regulate
room temperature. In addition, FanMaster can also be installed and used in
an evaluation only mode (without a fan drive). This mode allows the
FanMaster energy savings calculator to provide an estimate of potential
savings, prior to performing a full installation.

1-2 FanMaster Overview
FanMaster Externally Mounted Components
Temperature Sensors
Two temperature sensing probes are provided with FanMaster. These probes
are essential to FanMaster because the measured difference in temperature
between these sensors provides the command signal for the fan speed. The
temperature sensors are typically mounted on the outside of the Constant
Air Volume HVAC unit, with the sensing probe penetrating into the air flow
inside through a hole drilled into the side of the HVAC enclosure.
The placement of the Mixed Air sensor should be selected after examining
the interior of the HVAC unit to ensure that the probe is located in a position
that will accurately measure the temperature of the combined outside and
return air before entering the heating and cooling section. Avoid a location
that is in the upper, lower or edge portion of the air stream and one which
may be unduly influenced by the air entering the unit from the outside air
damper. If the Mixed Air temperature probe does not accurately reflect the
average temperature entering the heating and cooling elements, the fan
speed will not be set properly.
The supply air sensor should be mounted from 6 inches to 5 feet
downstream of the final heating or cooling element. Because the
temperature of the air can be warmer at the top of the air stream and cooler
at the bottom, the probe should be mounted as close to the vertical center of
the air flow as possible.
Carbon Dioxide Sensor
The CO2 sensor (if installed) is usually mounted in the room return air flow
of the HVAC unit prior to mixing with outside air. Alternatively, the CO2
sensor can be mounted directly on the return air duct work serving a specific
area that is most likely to be affected by high CO2 concentrations during
occasions of high occupancy. This will ensure that FanMaster will allow full
fan speed and normal ventilation when and where it is most needed. This is
the most typical installation.
Alternatively, the CO
space in an area that is most likely to be affected by high CO
concentrations during occasions of high occupancy. This will ensure that
FanMaster will allow full fan speed and normal ventilation when it is most
needed.
It may be desirable to invest in individual CO
locations. It has been found that certain buildings lack adequate ventilation
prior to installation of FanMaster. If FanMaster seems to be running in CO
override even during periods of low occupancy, it is advised that you seek
help from an HVAC air quality professional for advice on how to best
rectify the ventilation problems.

FanMaster Overview 1-3
Pressure Sensor (Optional)
In certain applications it may be necessary or desirable to maintain a
positive building pressure relative to the outside air. A pressure sensor can
be ordered with FanMaster which monitors the differential pressure
between the inside and outside air. When the differential pressure is lower
than a user specified setpoint, the FanMaster will override to 100% fan
speed to try to restore the desired minimum pressure differential. One
typical scenario where pressure override might occur is when a loading
dock door is opened to allow for a delivery, and additional airflow is
required to restore the pressure differential when the door closes. The sensor
requires connection to two lengths of 1/4 inch OD plastic tubing which
sample the inside and outside air pressure at their respective termination
points. You may need to experiment with the location of the tubing since
normal wind and airflow often causes localized air pressure deviations
around a building which may result in inaccurate pressure measurements.
You may find that the HVAC unit fan speed has no measurable affect on
building pressure. In this case turn off the pressure mode completely and do
not use the sensor.
When using a pressure sensor the Constant Ventilation mode described
below is not available.
Damper Position Indicator Switch
Many existing HVAC systems have a feature known as “economizer mode”
or “free cooling mode”. These systems monitor the outside air temperature
and humidity and when conditions are such that the outside air can be used
to provide cooling (instead of using the cooling element) the existing typical
system will open the outside air damper fully to allow maximum use of this
“free” cooling. FanMaster uses a Damper Position Indicator switch to
indicate when the existing control system is in economizer mode. The
switch is installed on the outside air damper in a location that causes its
contacts to close when the damper opens beyond the normal 10%
ventilation position.
In order to take full advantage of economizer mode, FanMaster increases
the speed of the fan to 100% until the existing control determines that
economizer mode is no longer appropriate. The economizer control will
then return the damper to its normal ventilation position and the contacts in
the damper position indicator switch will open. This signal is sent to
FanMaster, which allows the fan to return to its normal reduced speed and
damper override functions.
The switch must be installed in a position that will actuate when the damper
opens. It may be mounted directly on the damper blades, on the damper
actuator arms or linkage, or on the center axle of a damper blade section.
Because there are many different damper systems in use, the installation
may require fabrication of a custom linkage or mounting method if no
suitable location is available.

1-4 FanMaster Overview
Fan Starter Current Sensor
This device is used only when FanMaster is installed in evaluation mode.
The current sensor device is designed such that one wire lead of the existing
fan motor passes through its center. The current sensor has a switch that
actuates when it senses current flow in the motor wire, indicating that the
fan motor has been started by the existing control system. The actuated
switch identifies when the HVAC unit fan normally runs so the FanMaster
calculator can take into account the HVAC normal hours of operation and
more accurately project monthly cumulative savings.
Fan Starter Hard-Wired Interconnection
This device is used only when FanMaster is installed with a drive.
FanMaster requires a start signal from the existing BAS system in order to
know when to start and stop the fan. The control signal on the coil of the
existing fan motor starter provides this signal. The starter coil signal is
typically 115V AC or 26V AC. Two interposing relays, one that
accommodates each of these voltages, are shipped with FanMaster (120V
AC relay already installed at position CR4). Other control voltage relays are
available from Rockwell Automation.
FanMaster Operation
Fan Speed Reduction
With the installation of FanMaster, the existing HVAC control system
continues to maintain room temperature by monitoring its own temperature
sensors and controlling the heating and cooling elements. FanMaster
provides new, independent temperature sensors mounted in the airflow of
the HVAC unit. These sensors allow FanMaster to determine if the existing
controls are requesting heating and cooling and to adjust the fan speed to a
value appropriate for the amount of heating and cooling required.
As the existing controls call for more heating or cooling (as determined by
the amplitude of the temperature differential measured before and after the
heating and cooling elements), FanMaster responds by increasing the fan
speed. As the amount of heating or cooling required decreases, the
temperature differential decreases and so does the FanMaster fan speed. If
the existing controls are not calling for heating or cooling, then there is no
temperature differential across the heating and cooling elements and
FanMaster reduces the fan speed to a user specified minimum speed.
Reducing the HVAC unit’s fan speed when not calling for maximum heating
or cooling results in significant savings in the energy required to run the fan,
according to the Law of Affinity.

FanMaster Overview 1-5
Demand Ventilation Mode
A second source of energy savings is achieved by FanMaster's Demand
Ventilation mode. A typical Constant Air Volume HVAC unit is equipped
with a damper that allows a small percentage of outside air to be mixed with
the return air, maintaining an adequate CO
occupants. The damper is typically set during installation for a fixed volume
of fresh air, adequate for the worst case condition of full occupancy. The
outside air drawn in through this damper adds to the heating and cooling
load of the HVAC unit, since the outside air is seldom at the required
temperature for the building's occupants. In fact, depending on the local
conditions, the amount of heating or cooling energy which must be supplied
to this air can be quite costly.
When FanMaster reduces the fan speed as described above, it will also
reduce the amount of outside air brought into the HVAC unit. FanMaster's
demand ventilation technique monitors the amount of CO
and will override the reduced fan speed at any time the CO
above a user specified setpoint. This feature maintains an adequate level of
ventilation while reducing the cost of heating and cooling excess outside air
whenever possible.

The energy savings can be further enhanced by an optional feature which
allows FanMaster to fully close the outside air damper up to 50% of the
time when the CO

the outside air. The typical outside air damper has a spring return-to-close
mechanism and the existing controls are providing a signal maintaining the
10% open position. FanMaster provides an adjustable duty cycle electrical
relay which can interrupt the electrical signal to the damper allowing it to
close up to 50% of the time. This feature is overridden automatically by the
demand ventilation mode when the CO

Variable Ventilation Mode
This mode allows FanMaster to reduce the HVAC unit fan speed and
includes the option of allowing the damper to be overridden and closed 50%
of the time, exactly as with the Demand Ventilation mode. The difference is
that with the Variable Ventilation mode there is no CO
speed and damper operation are never overridden by the demand for
additional ventilation. This mode is designed for spaces such as warehouses
or manufacturing with limited occupancy or staffing relative to the volume
of the space and thus no opportunity for buildup of excessive CO
sensor and the fan

1-6 FanMaster Overview
Constant Ventilation Mode
Constant Ventilation mode can be used in specific applications requiring a
relatively constant flow of outside air be maintained for ventilation at all
times. This mode is not recommended for most installations as it precludes
the savings which may be realized by reducing the quantity of outside air
brought into the HVAC system. This is also the most difficult installation
due to the need to redirect the control signals for the outside damper control
into FanMaster and make new interconnections from FanMaster to the
outside air damper actuator.
If this mode of operation is enabled, FanMaster will continue to reduce the
fan speed to realize savings according to the Law of Affinity, but it will also
modulate the outside air damper open as the fan slows down in order to
maintain the same approximate quantity of outside air flow into the
building.
Estimated Savings Calculator
The FanMaster control system contains a calculator that provides an
estimate of the energy savings achieved by the reduction in fan speed and
reduction in outside air heating and cooling. The calculator uses the settings
provided by the user at startup and actual operating conditions, combined
with historical weather data for your selected location, to provide the
estimated cost savings achieved by FanMaster. The estimated energy costs
to run the HVAC unit with and without FanMaster are compared to
determine the savings.
FanMaster Application Considerations
Two State Heating or Cooling Control
Two state control of heating or cooling is used when the actual amount of
heating or cooling applied by the existing HVAC unit is fixed. That is, the
heating or cooling element is either on or off. FanMaster allows for the
selection of two state control for either heating or cooling or both. When
FanMaster is configured for two state control, it will run the fan at the
configured minimum speed when the temperature sensors detect that
heating and cooling are off, and will run the fan at the configured maximum
speed when the temperature sensors detect that heating or cooling is on.
This mode allows FanMaster to achieve energy savings during the time the
HVAC unit is idle and to allow maximum performance when the HVAC unit
is actively heating or cooling.
When in two state mode, the “Delta T Min” setup values for cooling and
heating determine when the fan speed transitions from “Min” to “Max”
speed. A typical value of five degrees is acceptable for most installations.
The “Delta T Max” setup values for cooling and heating have no effect on
operation in this mode, nor do any “SA (supply air) Override” settings.

FanMaster Overview 1-7
Proportional Heating and Cooling Control
Proportional control of heating or cooling is used when the actual amount of
heating or cooling applied by the HVAC unit is variable. That is, the heating
or cooling element is modulated by a mechanical or electrical valve. The
valve modulates how much heating or cooling is provided and is adjusted by
the existing control system to meet the actual demand. FanMaster allows for
the selection of proportional control for either heating or cooling or both.
When selected, FanMaster runs the fan at the minimum speed when the
temperature sensors detect that heating and cooling are off, and will vary the
fan from its minimum to its maximum speed proportional to the temperature
differential detected by the temperature sensors in the air flow before and
after the heating or cooling elements. This mode allows FanMaster to
achieve energy savings during the time the HVAC unit is idle and to
modulate the fan speed based on the amount of heating or cooling requested
by the existing control system, achieving an optimum energy requirement
based on the heating or cooling load.
When in proportional mode, the “Delta T Min” and “Delta T Max” setup
values for cooling and heating determine the slope of the fan speed increase.
A typical value of five degrees for “Delta T Min” is acceptable for most
installations. The “Delta T Max” setup value should be adjusted so that the
fan can achieve its maximum speed when the proportional valve controlling
heating or cooling is at 100%. The HVAC unit manufacturer can provide the
design delta T (temperature rise) of the specific unit for both heating and
cooling modes of operation. The heating delta T is typically higher than the
cooling delta T. If the unit is older or the delta T data is unavailable,
FanMaster can be initially run with the default values. The actual delta T
values of the unit can be determined by using the existing temperature
control setpoints to force the unit into a full heating or full cooling mode.
Adjust the room temperature to a very high or low setpoint and allow the
HVAC unit to run at 100% heating or cooling for about 30 minutes or until
the maximum delta T can be observed on the FanMaster System Status
screen. Perform this test for both heating and cooling. Use the actual
measured delta T values for the “Delta T Max” settings for heating and
cooling.
TIP: Although the maximum fan speed is adjustable, there is seldom a
reason to adjust this value to less than 100%. The only exception would be
for a system that is oversized to the point that the full horsepower capacity
of the fan is not required under any conditions. This could occur if the size
of the area heated or cooled is reduced after installation or if the HVAC unit
is oversized for other reasons. In this case, the maximum fan speed can be
safely reduced, provided that adequate capacity remains for extremely hot
or cold days. For reference, a reduction of the maximum speed to 95% will
deliver 95% of the airflow with a fan energy cost reduction of 16%. A
reduction to 90% reduces the fan energy cost by 23%.

1-8 FanMaster Overview
Supply Air Low Limit / High Limit Override
The supply air limit override setup values allow you to configure FanMaster
to run the fan at full speed as the supply air temperature reaches a low or
high limit. The default values are suitable for use in most cases. It is
desirable to limit the supply air temperature extremes to protect the HVAC
equipment. Increasing the fan speed to 100% as the temperature approaches
limits will provide this protection.
The supply air low temperature limit specifies the supply air temperature
below which FanMaster will run the supply air fan at full speed (100%) to
avoid freezing up the cooling system.
The supply air high temperature limit specifies the temperature above which
FanMaster will run the supply air fan at full speed (100%) to avoid
overheating the heating system.
In many installations the supply air limit overrides will never take effect
because the system is not capable of achieving the override temperature
limits under normal conditions. Also, the override temperatures will never
be used in two state heating or cooling systems since the fan is already at
maximum speed when the delta T exceeds the delta T minimum
temperature value.
Outside Air Damper Override
Additional savings can be achieved if the installation includes an outside air
damper with spring return-to-close, the existing system provides a signal to
open the damper to its normal outside air position (typically 10%), and the
supply override relay can be wired in a manner that interrupts the existing
control signal.
Systems Without Outside Air Dampers
FanMaster can be used with HVAC systems that do not have an outside air
damper. Even though no savings can be realized by reducing outside air,
reduced fan speeds will still provide energy savings.
Heating Only or Cooling Only HVAC Systems
The setup screens provide the ability to indicate whether or not heating or
cooling elements are used in the HVAC system. Setting these fields to “No”
indicates that heating or cooling is not available and will disable that portion
of the FanMaster operation and savings calculator.

Page 15
FanMaster Overview 1-9
Multi-Stage Heating or Cooling Systems
If the HVAC system has heating or cooling elements which turn on in more
than one step (e.g., low heat or high heat) FanMaster should be configured
for proportional control. This will allow the fan to run at minimum speed if
the heating and cooling are off. The fan will step to a medium speed at low
heating or cooling and step to maximum speed at high heating or cooling.
The heating and cooling Delta T Max fields should be set to a value that
ensures that the fan actually achieves maximum speed when high heat and
high cool are on.
HVAC Systems With No Return Air (100% Outside Air)
HVAC systems that draw all the air from the outside are also known as
Makeup Air Units (MAU) and are not suitable for FanMaster installations.
FanMaster control algorithms cannot determine proper fan speeds for these
type systems and cannot be used.
HVAC Systems with Electric Heating Elements Instead of Gas
FanMaster control algorithms work with either gas or electric heating
elements; both on-off or modulating types. The FanMaster energy
calculator calculates heating costs based on the user provided cost per
MMBTU of gas. If the HVAC unit has electric heating, an acceptable
estimation of heating costs can be achieved by setting a value for gas cost to
double the prevailing utility rate (electric heat is typically twice the cost of
gas). This will allow the calculator to estimate the cost of electric heat and
thus the savings values as well. Note that the FanMaster energy calculator
results are presented for informational purposes only, and do not affect the
actual control of the fan speed.
City Climate Data
If one of the pre-loaded cities in the FanMaster database does not provide a
comparable climate for the installation location, data for a “custom city”
can be entered during configuration.
A Compact Disk containing weather data for approximately 2000 locations,
both US and worldwide, can be obtained from the National Oceanic and
Atmospheric Administration (NOAA) at this URL:

data to be entered into the custom user data screen. The data presents the
BTU’s per CFM of ventilation air for each month of the year for the selected

BTU's are multiplied by the utility costs to estimate required energy costs,
both with and without FanMaster active.

Specific Setup Values
This section provides additional information for setting up specific
FanMaster configuration fields. The values entered in these fields help the
energy calculator to perform a more accurate estimate of energy savings and
are not used by the basic control algorithm and will not affect actual
savings.
• Heating Efficiency % - Use the manufacturer’s data sheet for the HVAC
unit to determine this efficiency. This value is a measure of how
efficiently the BTU capacity of the fuel purchased is converted into an
actual BTU delivered to the heated room. This value may be listed as an
AFUE (Annual Fuel Utilization Efficiency) rating. If this value is not
available, you may simply use the default value of 87% or adjust the
value up or down about 10% based on the age of the equipment (older
units typically having a lower efficiency).
• Minimum Damper Pos % - This value can best be approximated by
visually determining the angle or degree of openness of the outside air
damper in normal operation. 0% represents a damper fully closed and
100% represents a damper fully open. Typically, the damper will be
controlled by the existing HVAC or BAS system to about 10% open. If
desired, you can use a protractor to determine the actual angle and
convert it to a percentage, taking into account that dampers often appear
to be several degrees off-vertical when fully closed due to their
overlapping position. This value ultimately determines the percentage of
the total unit flow which is outside air and thus requires heating and
cooling to bring to a suitable room temperature.
Because the regulating effect of damper position on the volume of
airflow is very difficult to determine under the best of conditions, the
actual flow volume of outside air can only be roughly approximated by
this setting. However, a change in the setting of 1 or 2 percent will have a
10 or 20 percent effect in the estimations of the heating and cooling
BTU’s saved by FanMaster; so try to be as accurate as possible. This
value is used in the estimation of savings only and therefore does not
affect the actual realized savings.
• CO
Demand Setpoint ppm - If the CO2 sensor reports a value greater
2
than the setpoint, FanMaster allows the HVAC fan to increase to 100%
and will stop any override of the normal damper position. Outside air has
a typical range of 300 to 400 ppm CO

1-12 FanMaster Overview
• Pressure Low Limit InWC - This value sets the minimum inside vs.
outside air pressure. If the differential is below this value (in a negative
direction) the fan speed will increase to 100%. The default value of
-0.010 means the outside air pressure is just slightly higher than the
inside air. If necessary, adjust this value so that the fan only goes into
override speed when building doors are opened or if some other factor
requires periodic additional airflow. Do not set this value such that
FanMaster is in continuous override. You may find that the HVAC unit
fan speed has no measurable affect on building pressure. In this case turn
off the pressure mode completely and do not use the sensor.
Integration of FanMaster into Building Automation Systems
FanMaster provides an alarm contact for monitoring of faults by an existing
building automation system (BAS). This contact is normally closed when
FanMaster is operating properly. If power is not supplied to FanMaster or if
FanMaster detects certain conditions (see FanMaster Alarms on page 4-2
for a complete list) the fault contact will open. The alarm panel lamp on the
FanMaster unit will also be illuminated if any of the alarm conditions are
detected. The alarm contact and alarm lamp will return to normal when the
fault condition has returned to a normal state.

2-2 FanMaster Installation
Installation Considerations
Consider and plan for the following when installing FanMaster for
integration with an AHU:
• The existing BAS control supply fan start/stop signal. Two relays are
provided for interfacing to the BAS fan start/stop signal. The relay
installed in the FanMaster enclosure accommodates a 120V AC signal.
A second relay is shipped loose and accommodates a 24V AC signal. If
a signal other than 24V or 120V AC is used, you must purchase and
install the appropriate relay separately. The Allen-Bradley 700-HK
family of relays provides coil voltages from 6V AC…240V AC or 6V
DC…48V DC. More information is provided on the Allen-Bradley web
site at: http://www.ab.com/en/epub/catalogs/12768/229240/229266/
229643/229701/tab3.html
• The existing BAS outside air damper position control signal (used with
constant ventilation option only). FanMaster provides I/O connections
for a 4…20 mA signal only. If the BAS control signal is 0…10V DC or
0…135 Ohms, a converter adapter must be purchased separately for
both the input and output signals.
• When installing FanMaster with a Variable Frequency Drive, the
following firmware revisions must be used:
– PowerFlex 400, v1.004 and later
Installation Requirements
– PowerFlex 70EC v3.001 and later
– PowerFlex 700VC v4.001 and later
– PowerFlex 753 v1.005 and later
Power Source for FanMaster
120V AC, 10 Amp (min.) grounded service.
Tools Required for Installation
• Variable speed drill
• Sheet metal drill bits
• Various screwdrivers
• Various wrenches (open, socket and/or torque)
• Conduit cutting and bending tools (optional, for permanent

• Using the two screws and mounting flanges provided on the enclosure,
mount the supply air temperature transmitter to the outside of the AHU
sheet metal cover, in the middle of the supply air plenum. Placement
must be after the heating and cooling exchangers.
Important: Verify that the transmitter probe is installed in a position
that does not cause contact with any internal equipment
and that no internal equipment will be damaged while
drilling the insertion and mounting holes.
Mixed Air Temperature Transmitter
• Using the two screws and mounting flanges provided on the enclosure,
mount the mixed air temperature transmitter to the outside of the AHU
sheet metal cover, in the middle of the mixed air plenum. Placement
should be in a position where the outside air and return air are equally
mixed and the temperature reflects the average temperature entering the
heating and cooling exchangers.
Important: Verify that the transmitter probe is installed in a position
that does not cause contact with any internal equipment
and that no internal equipment will be damaged while
drilling the insertion and mounting holes.
Carbon Dioxide Sensor
• Using the two screws and mounting flanges provided on the enclosure,
mount the carbon dioxide sensor in the return air plenum. Placement
must be prior to the mixing of outside air with the return air.
Important: The carbon dioxide sensor will not operate properly
below 0° C (32° F).
Important: Verify that the sensor probe is installed in a position that
does not cause contact with any internal equipment and
that no internal equipment will be damaged while drilling
the insertion and mounting holes.

Important:If your are installing a PowerFlex 400, Style A, NEMA/UL
Type 3R, 4 and 12 drive with a factory installed HOA switch
and a speed potentiometer, you must place a jumper between
terminal 35 on TB1 in the drive enclosure and terminal 8 on the
drive signal terminal block. The Auto Start contact is not
required on this drive.
Important:If you are installing a PowerFlex 400, Style A, NEMA/UL
Type 1 drive, the optional inputs may be installed with the
exception of the Hand/Auto, Auto Start and Speed Reference
inputs.
Important:The FanMaster configuration and startup procedure (Chapter 3)
will set all necessary parameters in the PowerFlex 400 drive to
the correct settings. Therefore, those sections of the PowerFlex
400 drive installation and/or user manual which refer to setting
or configuring parameters should be ignored during
installation.
Important:PowerFlex 70EC, 700VC and 753 drives require manual
configuration of specific drive communication parameters
before completing the FanMaster configuration and startup
procedure. These steps are included later in this chapter.
Therefore, those sections of the PowerFlex 70EC, 700VC or
753 drive installation and/or user manual which refer to setting
or configuring parameters should be ignored during
installation.

14. If the existing fan motor starter provides an auxiliary open or closed
contact when the relay is energized, normal operation of the existing
control system may not be possible without this contact. Therefore,
disconnect the wires from the fan motor started contact and connect it to
the appropriate auxiliary contact terminals provided in the FanMaster
enclosure. The FanMaster auxiliary contacts actuate when the drive is
on and turning the fan. Refer to the schematic diagram, Figure B.4 on
page B-5, for details.
15. If using constant ventilation mode, continue with step 16 on page 2-17.
The FanMaster damper control override commands the damper to close
periodically in order to reduce the amount of outside air provided to the
AHU to further reduce costs associated with cooling and heating. The
damper override contact (at terminals 119 and 120 on TB2 in the
FanMaster enclosure) can be used to operate contact relay CR3 in the
FanMaster enclosure or a customer supplied interposing relay or
solenoid to close the damper when the output is turned on. Using the
damper override contact output to energize CR3 and wiring the existing
damper control or power signals through the normally closed contact on
CR3 will close the damper when the output is on.
Make the following connections for all installations. Refer to the
schematic diagrams in Figure B.2 on page B-3
page B-5 for details:
a. Install a jumper wire between terminals 1 and 152 on TB2 in the

shutdown due to opening the 4…20 mA loop or other failure to
follow command alarm.
Outside Air Damper with Pneumatic Actuator
The existing outside air damper has a pneumatic actuator with a mA
to Pressure controller (I to P):
i. Either remove the (+) control wire from the I to P and connect
through the relay as in steps “i. a.” and “i.b.” above, or obtain an
electrically actuated pressure valve which expels the pneumatic
actuator control air when the valve is actuated. Use the
FanMaster damper relay to switch power for the pressure valve
(separately sourced AC or DC power is required).
Outside Air Damper with Electric Actuator (0…135 Ohm)
The existing outside air damper has an electric actuator with a
0…135 ohm control signal:
i. Remove the (+) power supply wire from the actuator and
connect it to terminal 155 on TB2 in the FanMaster enclosure.
ii. Wire terminal 153 on TB2 to the actuator (+) power supply
terminal.
Important: The installer must determine and ensure the proper
operation of this contact when used to force the damper
closed.

– Verify that the supply air fan (and return air fan, if installed) is
rotating in the correct direction. During the test, the fan(s) will run.
If the fan(s) is not turning in the proper direction, you must reverse
any two motor leads.
– Set up the “Proof of Running” output. The existing proof of flow
sensor (flow switch or pressure sensor) may not provide accurate
proof of flow at a reduced fan speed. FanMaster will detect flow by
monitoring the torque current required by the supply fan at the
minimum speed. If the supply fan drive is not delivering 50% of this
current threshold, the proof of flow output turns off. The test allows
the system to capture the 50% threshold value by monitoring the
current supplied to the motor at the minimum fan speed.

Note: When the AHU cooling and heating elements are off but the
supply fan is running, the mixed air and supply air temperatures should
typically be within a few degrees of each other, indicating proper
calibration and operation.

FanMaster Status
You can determine the operating status of the FanMaster in the following
ways:
• Alarm indications. An alarm banner (example shown below) will display
on the PanelView terminal to indicate a problem. Refer to FanMaster
Alarms on page 4-2 below for more information.
• Air Handler Unit Diagram screen on the PanelView terminal. This screen
provides an overview of a typical AHU configuration and current
FanMaster readings. If a value is out of range (OOR) or above a set limit,
or a communication fault (Comm Fault) has occurred, in addition to the
display of an alarm banner (described above), “OOR” or “Comm Fault”
will display in place of the reading for the affected device. Refer to Air
Handler Unit Diagram Screen on page C-3 for more information.
• FanMaster Faulted indicator light. This light, located on the front panel
of the unit, will turn on when an error condition exists in FanMaster and/
or connected drive (if installed). The light will turn off when the error
condition is cleared.
• FanMaster Faulted signal. An optional dry contact output that remains
closed when FanMaster is energized and is not faulted and opens when
FanMaster is de-energized or is faulted. This output can be monitored by
an external system for indication of proper FanMaster operation. Refer to
