Before installation, careful consideration must be
given to how this system will operate if connected
to any other piece of mechanical equipment, i.e. a
forced air furnace or air handler, operating at a
higher static. After installation, the compatibility of
the two pieces of equipment must be confirmed, by
measuring the air flows of the HRV, by using the
balancing procedure found in this manual.
NEVER install a ventilator in a situation where its
normal operation, lack of operation or partial
failure may result in the backdrafting or improper
functioning of vented combustion equipment.
WARNING
• Disconnect the power from the unit before
cleaning or servicing.
• To prevent electrical shock, it is extremely
important to confirm the polarity of the power line
that is switched by the safety (disconnect) switch.
The hot line (black) is the proper line for switching.
Use either a voltmeter or test lamp to confirm the
absence of a voltage between the disconnect
switch and ground (on the cabinet) while the door
is open. This procedure must be followed, as
dwellings are occasionally wired improperly.
Always enure the proper grounding of the unit.
ATTENTION
• Do not apply electrical power to the unit until after
the completion of the installation (including the
installation of low voltage control wiring).
• Ensure the Installation and wiring is in
accordance with CEC, NEC, and local electrical
codes.
IMPORTANT PLEASE READ THIS MANUAL
BEFORE INSTALLING UNIT.
• Due to ongoing research and product
development, specifications, ratings, and
dimensions are subject to change without notice.
• Plug the unit into a standard designated (120
VAC) electrical outlet with ground.
NOTE
•The use of an extension cord with this unit is not
recommended. If the installation requires further
wiring, have a licensed electrician make all of the
electrical connections. The recommended circuit is
a separate 15 amp/120 volt circuit.
• Due to ongoing research and product
development, specifications, ratings, and
dimensions are subject to change without notice.

Getting to Know your Heat and Energy Recovery Ventilator (FC Series)
• Recovers the majority of the energy contained in the exhausted
stale air.
• Uses the recovered energy to preheat or precool the fresh outdoor
air introduced into the house
• Distributes the fresh air throughout your home.
Thank you for purchasing a Field Control Heat/Energy Recovery
Ventilator (HRV/ERV). The HRV/ERV provides fresh air to your
home while recovering energy from the air it exhausts.
There are numerous benefits to a properly installed, operated, and
maintained HRV/ERV:
• Exhausts the stale, contaminated air, found in today’s tight
buildings.
Ventilation and Control Options*
• The Dehumidistat Ventilation Control (DHVC) is a manual
control which features ON/OFF, High speed, Low Speed, and an
electronic dehumdistat.
Optional Controls are available to adjust the amount of ventilation
in your home:
• The Healthy Home System™ Control (HHSC) will automatically
deliver fresh air to your home.
• The Dehumidistat Control (DHI) can be used in conjunction with
the HHSC to provide additional ventilation for high indoor
humidity levels.
*Refer to the individual control pages of this manual for more
information about these controls.
How the Dehumidistat Works (Colder Climates)
Refer to the main control instructions located in the Operation and
Installation Manual for instructions on how to set the dehumidistat.
The dehumidistat function on the main control should be set to OFF
for all seasons except the heating season, because a dehumidifying
effect occurs only when the outdoor air is dryer than the indoor air.
Set the RH level to 80 to turn the dehumidistat OFF. (Refer to the
control instructions for information on how to set the
Dehumidistat).
DEHUMIDISTAT DISABLE - automatically disables the
dehumidistat function on the main control when outdoor
temperatures exceed 15°C (59°F) for a full 24 hour period. All other
HRV features and functions operate normally while the
dehumidistat function is disabled.
DEHUMIDISTAT RE-ENABLE - automatically re-enables the
dehumidistat function if either the outdoor temperature drops below
15°C (59°F) for a full 24 hour period or if the HRV is reset
(unplugged for 30 seconds).
High indoor humidity levels, during the heating season, have
become a problem in many well insulated, tight homes. Excessive
condensation on the windows is a visual sign of high indoor
humidity levels. High indoor humidity levels can result in mold and
mildew and the eventual degradation of the building structure itself.
Your HRV/ERV reduces indoor humidity levels when the
outdoor air is drier than the indoor air. These conditions usually
occur during the heating season when outdoor temperatures are less
than 15°C (59°F). During the heating season, the operation of the
HRV/ERV may reduce indoor humidity levels sufficiently to
eliminate the need for further dehumidification.
If your home requires further dehumidification, use the
dehumidistat feature located on any optional main control (refer to
the Operation and Installation Manual for Optional Control
information). This feature aggressively addresses high indoor
humidity levels by initiating high speed ventilation when the indoor
humidity levels rise above the adjustable set point on the control.
Glossary and Additional Information
SELF-TEST - Each time the HRV/ERV is powered/energized, the
self-test function automatically initiates. The HRV/ERV cycles
through the available speeds and tests the damper motor operation.
The HRV/ERV defaults back to the previous operational mode and
speed selection after the self-test (approximately 60 seconds in
duration).
DEFROST MODE - To ensure reliable operation during cold
weather, the HRV automatically cycles through its defrost mode
when the outdoor temperatures drop below freezing.
HRV/ERV - a Heat Recovery Ventilator (HRV/ERV) is designed
to provide fresh air into a building while exhausting an equal
amount of stale air. During the winter months, heat recovered from
the stale air, before it is exhausted to the outdoors, warms the
incoming cold fresh air. During the summer months, when the
indoor space is air conditioned, the HRV/ERV helps to cool the
incoming fresh air with the cool exhausted stale air.
STANDBY - The HRV/ERV is powered/energized and waiting for
ventilation to be initiated by an external control.
TIMERS - These optional controls may be installed at specific
exhaust locations (bathrooms etc.) to initiate high speed ventilation.

Healthy Home System Control (HHSC)
The Healthy Home System Control (HHSC) activates the
HRV/ERV automatically to deliver fresh air into your home.
Setting the Control
The duration of the ventilation rate is adjustable on the HHSC.
Your installer sets up this control during the installation of your
system . Refer to the instructions that came with the HHSC for the
setup information.
The Healthy Home System™ Control (HHSC)
Dehumidistat (Part DH1)
Your HRV/ERV system produces a dehumidifying effect when
outdoor humidity levels are lower than indoor humidity levels.
These conditions occur normally when outdoor termperatures are
below 60°F. An additional dehumidification effect is achievable
with the Optional Dehumidistat (Part DH1).

Home System Control (HHSC). The DH1 will initiate high speed
ventilation when the moisture level in the home exceeds the set
point on the control. Once the humidity in the house is reduced,
the HRV will revert back to the HHSC automatic setting. The
Dehumidistat should be set to OFF for all seasons except the
heating season.

Maintenance Routine for HRV
1. Inspect Exterior Hoods at least once a month.
6. Clean Duct Work if Required
The duct work running to and from the HRV may accumulate dirt.
Wipe and vacuum the duct once every year. You may wish to
contact a Heating/Ventilation company to do this.
WARNING: Blockage of hoods may cause an imbalance.
7. General Maintenance - Twice a Year
Make sure exhaust and fresh air supply hoods are not blocked or
restricted by leaves, grass, or snow. In winter, it is especially
important to make sure snow is not blocking the hoods or that frost
has not built up on the wire mesh (bird screen).
Wipe down the inside of the cabinet with a damp cloth to remove
dirt, bugs, and debris that may be present.
2. Clean Air Filters (clean twice a year)
The standard filters equipped with your HRV are removable and
washable.
8. Cleaning the Fans
Fans may accumulate dirt causing an imbalance and/or excessive
vibration of the HRV. A reduction in the air flow may also occur.
In new construction this may result within the first year due to
heavy dust and may occur periodically after that over time
depending on the outdoor conditions.
a) simply open access door and slide core out
b) remove filter clips
c) once clips are removed filters can be taken off the core to be
rinsed with water or a combination of mild soap and water. Do
not clean in the dishwasher
• unplug the HRV and open the service door
• remove the core
d) to re-assemble, place clean filter(s) (wet or dry) back into their
positions against the core and return clips to their original
position
• remove ducting (metal and/or flexible insulated type) from
the red and/or blue ports which are connected immediately
in-line with the fan assembly
e) slide core back into its’ original position
• use a small brush, such as an old toothbrush or pipe cleaner,
and insert first
3. Clean Core Twice a Year
a) open access door.
b) carefully grip ends of core and pull evenly outward. Core may
be snug, but will slide out of the channel
(a) through the large opening of the fan
assembly and then
c) once removed from the cabinet remove filters
(b) through the smaller opening in the end
of the fan assembly.
d) wash core in warm soapy water (do not use dishwasher)
e) install the clean filters
• scrub individual fan blades until clean. Avoid moving or
damaging balancing flat weight, clip is usually found on one
or more of the fan blades
f) install clean core
Note: Core installation label on the outer end of the core.
• vacuum and wipe
To install the clean core:
a) first mount the bottom flange of the core guide into the bottom
H channel approximately 1/4” (6mm)
• reassemble making sure ducting is reattached firmly and
insulation and moisture barrier are sealed and taped
b) mount the left or right side flange of the core guide
approximately 1/4” (6mm) followed by the other side
c) mount the top flange of the core guide into the top H channel
approximately 1/4” (6mm).
Before attempting this task, thought should be given to having a
qualified service technician complete the service work.
d) with all four corners in place and the core straight and even,
push hard in the centre of the core until the core stops on the
back of the cabinet.
WARNING
NOTE: Core will appear to stick out from cabinet approximately 1/8”
(3mm). This is designed this way so that the access door will fit tight
against the core.
Electric shock hazard. Can cause
injury or death. Before attempting to
perform any service or maintenance,
turn the electrical power unit OFF at
disconnect switch(es). Unit may have
multiple power supplies.
4. Motors - Maintenance Free
5. Drain (condensate) Line - Clean once a year
Inspect drain line, drain spout, and “P” trap for blockage, mould or
kinks. Flush with warm soapy water and replace if worn, bent or
unable to clean.

Port Configuration and Airflow
Model FC95HRV
In order to make the HRV as space efficient as possible, the
INDOOR supply and return ports are converted from round to oval
shape. Overall size of the port remains the same. Simply bend a
standard duct fitting to the correct shape, and attach to the oval
port using the same method as for a round port.
Round port bent to oval
FC95HRV Air Flow
Stale air enters the FRONT-RIGHT side port. The air passes down
the front half of the core, then up the back half of the core and out
the RIGHT-REAR port.
Fresh outdoor air enters the LEFT-REAR port and passes down
the back half of the core. Then the fresh outdoor air passes up the
front half of the core and out the LEFT-FRONT port. This
configuration allows the air to actually travel through the core
twice, which makes the FC95HRV nearly as efficient as a double
core unit.

Installation Methods
The Three Methods of Installation
The following three installation methods are for the
HRV/ERV system:
• The Simplified installation.
• The Partially Dedicated Installation
• The Fully Dedicated Installation
Installing the Ducting Between the HRV/ERV &
Living Areas in the House
A well designed and installed ducting system will allow the
HRV/ERV to operate at its maximum efficiency.
All ducts should be kept short and have as few bends or
elbows as possible to maximize airflow. Forty-five degree
elbows are preferred to 90° elbows. Use "Y" tees instead of
straight tees whenever possible.
All duct joints must be fastened with screws, rivets or duct
sealant and wrapped with mastic or quality duct tape to
prevent leakage. Mastic is preferred but if duct tape is used,
we recommend aluminum foil duct tape.
Galvanized (rigid) ducting from the HRV/ERV to the living
areas in the house is recommended whenever possible
although flexible duct can be used in moderation if
necessary.
A short length (approximately 12 inches or 300mm) of nonmetallic flexible insulated duct should be connected
between the HRV/ERV and the supply/exhaust duct system
to avoid possible noise transfer through the duct system.
All ducts running through attics and unheated spaces must
be sealed and insulated to code.
Simplified Installations
The Simplified Installation draws stale air from the cold air
return duct of the air handler/furnace and introduces an
equal amount of fresh air farther downstream into the cold
air return. Refer to "Simplified Installation Diagrams".
The air handler/furnace blower must be running when the
unit is operating for this system to be effective. Refer to
"Interlocking the HRV/ERV to an Air Handler/Furnace
Blower".
Partially Dedicated Installations
The Partially Dedicated Installation draws stale air from
specific points in the house and introduces an equal amount
of fresh air into the cold air return. Refer to "Partially
Dedicated Installation Diagrams".
Stale air ducts should be installed in areas of the home
where the poorest indoor air quality exists (bathrooms and
kitchen). Each location with a stale air duct should have a
timer to initiate high speed ventilation. Refer to "Optional
Timers" in this manual.
ATTENTION
Applications such as greenhouses, atriums,
swimming pools, saunas, etc. have unique
ventilation requirements which should be
addressed with an isolated ventilation system.
The air handler/furnace blower should be running when the
HRV is operating to evenly distribute the fresh air
throughout the house. Refer to "Interlocking the HRV/ERV
to an Air Handler/Furnace Blower".
Fully Dedicated Installations
The Fully Dedicated Installation draws stale air from
specific points in the house and delivers fresh air to specific
locations of the house. This system is not connected to an
air handler/furnace. Refer to "The Fully Dedicated
Installation Diagrams" in this manual.
Stale air ducts should be installed in areas of the home
where the poorest indoor air quality exists (bathrooms and
kitchen). Each location with a stale air duct should have a
timer which will initiate high speed ventilation. Refer to
"Optional Timers" in this manual.
Fresh air ducts should be installed to all bedrooms and
living areas, excluding bathrooms, kitchen and utility areas.
Grilles should be located high on a wall or in ceiling
locations. Grilles that diffuse the air comfortably are
recommended. Refer to "Grilles" in this manual. Special
care should be taken in locating grilles if the floor is the
only option available. Areas such as under baseboard
heaters will help to temper the air.
Optional in-line duct heaters are available for mounting in
the supply duct work to add heat if required.
13
Simplified Installation Diagrams
Simplified Installation (Return/Return Method)
Key Points
• The HRV/ERV must be balanced.
• It is mandatory that the furnace blower run continuously or
HRV/ERV operation be interlocked with the furnace
blower. (Refer to “Interlocking the HRV/ERV to an Air
Handler/Furnace Blower.”)
• The duct configuration may change depending on the
HRV/ERV model. See specifications for your unit.
• Check local codes / authority having jurisdiction for
acceptance.
• A backdraft damper is required in the exhaust air duct to
prevent outdoor air from entering the unit when the
Furnace/Air Handler is running and the unit is in Standby,
OFF or Recirculate.
Sizing the Ductwork
It is the responsibility of the installer to ensure all ductwork is
sized and installed as designed to ensure the system will
perform as intended.
The amount of air (cfm) that an HRV/ERV will deliver is
directly related to the total external static pressure (E.S.P.) of
the system. Static pressure is a measure of resistance imposed
on the blower by length of duct work plus the number of
fittings used in the duct work.

Weatherhood Installation
Installing the Ducting from the
Weatherhoods to the HRV/ERV
Weatherhoods
Fixed covered weatherhoods have a built-in bird screen with a 1/4"
(6mm) mesh to prevent foreign objects from entering the
ductwork.
The inner and outer liners of the flexible insulated duct must be
clamped to the sleeve of the weatherhoods (as close to the outside
as possible) and the appropriate port on the HRV/ERV. It is very
important that the fresh air intake line be given special attention to
make sure it is well sealed. A good bead of high quality caulking
(preferably acoustical sealant) will seal the inner flexible duct to
both the HRV/ERV port and the weatherhood prior to clamping.

To provide the occupants with direct access to the functions
of the controls, install optional accessory controls
throughout the house.
How To Install the Controller
1. Separate the HHSC controller cover from the wall plate
(mounting base) to expose mounting holes
(see illustration).
2. Route wires through large hole in the mounting base.
Mount base against wall and mark wall through
3 mounting holes.
3. If mounting on a metal or wood surface, drill three 1/8-in.
pilot holes in wall where marked for the supplied
mounting screws. If mounting on drywall or other
surface, drill appropriate holes for wall anchors or other
means of attachment.
4. Secure mounting base to wall with either the 3 screws
provided or other fasteners, while ensuring that all wires
extend through the hole in mounting base.
5. Adjust length and routing of each wire to reach the
proper terminal and connector block on mounting base,
while leaving a 1/4 in. length of extra wire. Strip only
1/4 in. of insulation from each wire to prevent adjacent
wires from shorting together when connected.
6. Connect wires to their respective terminals on the
connector block. (Figure 1) Both (R) and (C) must be
connected for proper operation. Improper wiring or
installation may damage the controller. Ensure wiring is
correct before proceeding with installation or turning the
unit on.
7. Push any excess wire into wall and against mounting
base.
8. Snap cover onto base, while ensuring pins align with
sockets in connector.
9. Once powered the HHSC automatically enters into
operating mode.
HRV/ERV control. The HHSC is also typically used to
control an FAD fresh air damper.
2. Complete all wiring connections before restoring power
to the HVAC system and HRV/ERV.
Programming the HHSC Control
1. Balance the fresh and stale airflows as instructed in this
manual.
2. Determine the cfm flow rate as instructed in this manual.
3. To obtain the desired rate of fresh air exchange, refer to
the HHSC Control Installation Instructions to determine
the On/Off timer settings for the HHSC Control. Use the
cfm flow rate determined in step 2 as the computed or
measured fresh air flow rate (as calculated in the HHSC
instructions). To ensure adequate ventilation, ensure that
the “Fan On” time is equal to or greater than the “Vent
On” time, as programmed in the HHSC Control.
4. For continuous operation of the HRV/ERV, set
“Fan On” and “Vent On” to “Un” (unlimited), and “Fan
Off” and “Vent Off” to any setting except “Un”. This
setting also causes the HVAC fan to run continuously.
NOTE: The HHSC Control is factory programmed with the
default settings of the two On/Off timer values. No
configuration is required to use these factory default
settings.
Default settings:
FAN OFF
20 minutes
FAN ON
10 minutes
VENT ON

Interlocking the HRV/ERV to an Air Handler/Furnace Blower
Connecting the HRV/ERV as illustrated will ensure the Air
Handler/Furnace Blower Motor is operating whenever the
HRV/ERV is ventilating.
CAUTION
The HRV/ERV must be interlocked to the Furnace/Air
Handler with a Simplified Installation (Return/Return
Installation) and should be interlocked with a Partially
Dedicated Installation.
Consideration should be given to competing
airflows when connecting the HRV/ERV in
conjunction with an Air Handler/Furnace Blower
system.

Setting “Standby” when using a Main Control
The HRV/ERV will be “fully-off” when the
OFF position is selected on the Main Control.
Timers and /or other controls will not function
when the HRV/ERV is in the OFF position.
The “fully-off” feature can be modified to
“standby-off” by adding a jumper on the
Terminal Block between 2 (ON) and 3 (RED).
“Standby” can also be achieved by setting the
main control to the ON position and selecting
speed 0*. Timers and /or additional controls
will initiate high speed ventilation when
activated.
* Speed 0 is not available on all controls
CAUTION
Building codes in some areas require “fullyoff” functionality. Check with your local
building authority before modifying the unit
to “standby -off”.
Unintentional operation of the HRV by the
end user may occur if the unit is modified
from “fully-off” to “standby-off”.
The Terminal Block

Operating the HRV/ERV without a Main Control and Adding Dry Contact Controls
A jumper must be in place between 2 (ON) and
3 (RED) on the Terminal Block to activate the
HRV/ERV for timers and/or dry contact
controls.
The HRV/ERV must have a Jumper in
place between 2 (ON) and 3 (RED) on
the Terminal Block when installing the
unit without a Main Control.
Adding Dry Contact Controls
Low Speed - A jumper between 2 (ON) and
1 (LOW) initiates low speed ventilation.
High Speed - A jumper between 2 (ON) and
6 (HI) initiates high speed ventilation.
Dehumidistat - A dry contact for a dehumidistat
is connected between 2 (ON) and 10 (BLK).

Balancing the Air Flows
Balancing the air flows is critical to ensuring that the amount of air introduced from the outside of the building equals the
amount of air exhausted to the outside of the building. If these two air flows are not properly balanced, the following issues
may occur:
• A positive or negative pressure may occur in the house
• HRV/ERV may not operate at its maximum efficiency
• The unit may not defrost properly
ATTENTION
Air Flow Measuring Gauges
The magnehelic gauge and the digital manometer are suitable
instruments for the balancing of air flows.
A magnehelic gauge with a scale of 0 to .25" w.c. is suitable
for accurately measuring air duct velocity. The value on the
gauge will be velocity pressure. A digital manometer requires
the ability to display differential pressures at 3 digits of
resolution.
Gauge Attachments
When sampling an air flow, various attachments are available
for use on a magnehelic gauge or digital manometer.
Continuous, excessive, positive pressure may
drive moist indoor air into the external walls of
the building. Once inside the external walls, moist
air may condense (in cold weather) and degrade
structural components or cause locks to freeze.
Continuous, excessive, negative pressure may
have several undesirable effects. In some
geographic locations, soil gases such as methane
and radon gas may be drawn into the home
through basement or ground contact areas, and
may also cause the backdrafting of vented
combustion equipment.
The following illustration shows a magnehelic gauge with
a scale of 0 to .25" w.c. with a pitot tube attachment. This
combination will measure the system air velocity pressure
accurately, regardless of the duct size or shape (either round
or rectangular).
Balancing Preparation
Prior to performing the air balancing procedure, perform the
following steps:
• Seal the ductwork system
• Confirm the installation and proper operation of all the
components of the HRV/ERV
• Fully open the balancing dampers
• Turn off all household exhaust devices (range hood, clothes
dryer, bathroom fans)
• Set the HRV/ERV at high speed
• Prior to balancing the unit, first adjust air flows in branch
lines to specific areas of the house
• If the outdoor temperature is below 0˚C (32˚F), ensure the
unit is not running in defrost
• Place the magnehelic gauge on a level surface and adjust it
to zero
• If the system is a Simplified or Partially Dedicated
installation, operate the furnace/Air Handler at high speed

A) Review the readings and damper down the duct with the
highest duct velocity pressure. Repeat Step 2 and Step 3
until both ducts show indentical readings. For this example,
the Fresh Air to Building air stream has the highest duct
velocity pressure.
Determining the cfm
After balancing the air flows, calculate the cfm flow rate.
Example
This example shows how to determine the air flow for a 6” diameter duct.
As shown in the illustration, the duct velocity pressure reads 0.025” w.c.
on the magnehelic gauge. Use the chart that came with the magnehelic
gauge to determine a duct velocity of 640 feet per minute for a duct
velocity pressure of 0.025” w.c.
Cfm Calculation
cfm = feet per minute x cross section area of duct
= 640 x 0.196
= 125
Cross Section Area of some common round duct sizes:
0.087 for 4” diameter duct
0.136 for 5” diameter duct
0.196 for 6” diameter duct
0.267 for 7” diameter duct
Magnehelic Gauge reading .025” w.c.

Step 7
Step 1
Prepare the air flow measuring device (i.e. Magnehelic Gauge or
Digital Manometer) by connecting the hoses to the low and high
pressure side of the gauge.
Refer to the "Airflow Reference Chart" for your model and
determine the FRESH AIR and STALE AIR flow rates (the chart is
located on the lower portion of this page).
Insert the hoses into the rubber fittings from the optional Door Port
Adapter Kit (part # 99-182). Use light pressure and rotate until
fitting is snug. Do not extend the hose past the rubber fitting.
Step 9
Step 8
Step 2
Damper down the higher airflow and repeat Steps 5 to 7 as required
until both airflows are identical (balanced).
Step 3
Remove the tape and rubber fittings and reinstall the 4 Door Port
Covers.
Open the HRV Door. Remove the 4 Door Port Covers by carefully
pushing them out from the back side of the door (use the blunt end
of a large drill bit etc.).

Balancing Dampers
The FC155HRV and FC200HRV models have factory installed
Balancing Dampers located in the “Fresh Air to Building” and
“Stale Air from Building” collars.
All other units require the installation of balancing dampers (not
included) in the “Fresh Air to Building” and “Stale Air from
Building” ductwork. Refer to the installation diagrams in this
manual for the Simplified, Partially Dedicated, and Fully
Dedicated systems.
NOTE
Installations where the HRV is ducted directly to
the return of the furnace/Air Handler may
require additional dampening on the fresh air to
building duct.
This is due to the high return static pressures
found in some furnace installations.
Observe the location of the screws
when connecting ductwork to the
collar. Screws should be located no
further than 1/2” from the outside
edge of the collar and they should
be no longer than 3/4”.
Push and turn with slotted
screwdriver. Damper
automatically locks when
pressure is released.
