Terms & Definitions
Defrost Mode (HRV)to ensure reliable operation during
cold weather, the HRV will automatically cycle through its
defrost mode as needed.
Dehumidistata control device that senses the amount
of moisture in the air and activates high−speed ventilation
when the air moisture level exceeds the set point.
Resetwhenever resetting of the HRV/ERV is required,
simply unplug the power cord for 30 seconds. The Self Test
will occur when the HRV/ERV is reconnected.
Self Testeach time the HRV/ERV is powered/ener-
gized, the self test function will automatically initiate. Dur-
ing the self test, the HRV/ERV will cycle through all the
speeds available (1 − 5), test the damper motor operation,
and will default back to the previous operational mode and
speed selection. Total self test duration is approximately
90 seconds.
Standby Modethe HRV/ERV is powered/energized and
waiting for fan operation to be initiated. For example, the
HRV is set to Continuous Ventilation Operational Mode at
speed 0.
Thermistorthe HRV/ERV’s temperature sensor which
measures electrical resistance in a known manner, as out-
door temperatures fluctuate.
HVIHome Ventilating Institute.
R2000Canada Home Building Energy Efficiency Stan-
dard.
HRAIHeating Refrigeration Air Conditioning Institute.
Application
The Healthy Climate® Heat Recovery Ventilator (HRV)
and Energy Recovery Ventilator (ERV) are designed to
provide fresh air while exhausting an equal amount of stale
air. Refer to application map on page 42.
The HRV unit is equipped with an aluminum core. The de-
vice uses the stale air that is being exhausted to condition
the fresh air as it is being brought in.
The ERV unit is equipped with an enthalpic core. This de-
vice is designed for use in warm, humid climates with
heavy air conditioning loads. The ERV unit transfers both
sensible (temperature) and latent (moisture) heat from in-
coming fresh air to the stale air as it is being exhausted;
thus, reducing the air conditioning load. The ERV unit is not
suitable for use in climates where the temperature drops
below 25ºF (−4ºC) for more than 5 days continuously.

HRV3−095 Air Flow Direction
The top half of the unit is divided front to back. This unique configuration allows the air to actually travel through the core
twice, making the HRV3−095 unit almost as efficient as a double core unit.
Stale air enters the front right side port. The air will pass down the front half of the core, then up the back half of the core
and out the right rear port.
Fresh outdoor air will enter the left rear port and pass down the back half of the core. It will then pass up the front half of the
core, and out the left front port.
Defrost Cycle (HRV)
The HRV has an electronically controlled defrost system.
The defrost cycle is activated when the outdoor tempera-
ture drops below 27ºF (−3ºC). There are three levels of de-
frost mode based on the outdoor temperature. Incoming
fresh air is measured to set the defrost times and the run
times while in the defrost mode. The three defrost settings
are:
SAt 27ºF (−3ºC) HRV runs in defrost for 3 minutes and
runs in ventilation for 25 minutes
SAt −4ºF (−20ºC) HRV runs in defrost for 4.5 minutes and
runs in ventilation for 17 minutes
SAt −31ºF (−35ºC) HRV runs in defrost for 7 minutes and
runs in ventilation for 15 minutes
No remote device can override this defrost mode or se-
lected speed until the cycle is complete. After the cycle is
completed the HRV defaults to previous settings. If the
cycle is completed and the thermistor continues to mea-
sure defrost temperature the defrost cycle is repeated.
ERV’s have no defrost cycle and are not recommended
where outdoor temperatures fall below 25ºF (−4ºC) contin-
uously for more than 5 days.
Recirculating Damper Defrost (HRV3−095,
HRV3−150−TPD, HRV4−150, HRV4−200)
During defrost a motor driven damper door mechanism
closes off the supply air from outside allowing exhaust air
to recirculate through the unit’s core. During defrost cycle
no ventilation is occurring. After the defrost period, the
damper operates in the opposite direction to reopen the
fresh air port. Defrost cycle repeats until the temperature
rises above 27ºF (−3ºC).
Damper Defrost − 5 port Models (HRV3−195/300)
During defrost a motor driven damper door mechanism
closes off the supply air from outside allowing a fifth port to
open enabling warm air to be drawn in from around the
unit. During defrost cycle stale air exhaust is still occurring.
After the defrost period, the damper operates in the oppo-
site direction to reopen the fresh air port. Defrost cycle re-
peats until the temperature rises above 27ºF (−3ºC). (The
defrost port can also be ducted to another location.)
Fan Defrost (HRV3−150−TPF)
During defrost cycle, the Fresh Air supply motor will shut
off and the Stale Air exhaust motor will continue to run.
After the defrost period, the Fresh Air supply motor will re-
sume. Defrost cycle repeats until the temperature rises
above 27ºF (−3ºC).
6" Diameter
SAME CIRCUMFERENCE
In order to make the HRV3−095 unit as space efficient as possible, the
indoor supply and return ports are converted from round to oval
shape. Circumference 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.

Requirements
Connecting appliances to the HRV/ERV unit
The following appliances should not be connected to the HRV/ERV unit:
Sclothes dryer
Srange top
Sstove top fan
Scentral vacuum system
NOTE − Failure to follow this instruction will void the HRV/ERV unit warranty.
DANGER
Risk of Carbon Monoxide Poisoning and/or Explosion.
Can cause injury or death.
Combustion and flue gases from heating appliances must never be allowed to enter living spaces.
HRV/ERV unit must be properly balanced (see page 28 or 31) to prevent negative pressure in structure. Negative
pressure can cause back−drafting of combustion gases in other household appliances such as Gas Furnaces,
Oil Furnaces, Hot Water Heaters, Wood Stoves, Fireplaces, etc.
(5-Port HRV models only) Defrost cycles will cause negative pressure in equipment room. Install ductwork and
route to areas that do not contain appliances with vented combusted gases.
Never connect a return or supply duct to other heating units such as fireplaces, wood stoves.
CAUTION
Potential equipment malfunction or damage.
May require repairs and/or void warranty.
Do not interconnect HRV/ERV to other appliances such as Stove Vents, Clothes Dryer Vents, Central Vacuum
Systems, Auxiliary Fans, etc.

Controlling the HRV/ERV
Today’s modern, air tight homes require fresh outdoor air
to maintain a healthy indoor air environment. The amount
of ventilation required in a home depends upon:
Sthe number of occupants and their activity levels.
Sthe way the home was built,
Spersonal preferences for fresh air.
The HRV/ERV introduces fresh air to your home while re-
covering energy from the air it exhausts. Specifically, an
HRV/ERV that is properly installed, operated, and main-
tained will:
Sexhaust stale, contaminated air,
Srecover the majority of the energy from the exhausted
stale air,
Suse the recovered energy to preheat or precool out-
side air that is drawn into the house,
Sdistribute the fresh air throughout the house.
How much ventilation is needed?
During seasons when windows and doors are closed (win-
ter and summer, if air conditioned) the HRV/ERV should be
set to operate continuously on low speed with the option of
going to high speed as the need arises. For example, if a
large number of people are present in the home, the unit
should be switched temporarily to high speed. Conversely,
when the home is unoccupied, an intermittent operational
mode (e.g. 20 minutes on / 40 minutes off) may be used.
Electronics
All units include a Wall Control. Optional controls can be
installed at the time of the installation or at a later date, pro-
viding a number of choices for upgrading the basic fea-
tures of the ventilation system.
Dehumidistat Operation
Often, well insulated and air tight homes will have high in-
door humidity levels during the heating season. High hu-
midity levels are apparent from the visible condensation on
windows. The amount of condensation on the windows will
increase as outdoor temperatures drop.
The HRV/ERV will reduce indoor humidity levels when out-
door air is drier than indoor air. This usually occurs during
the heating season when outdoor temperatures are less
than 59ºF (15ºC).
HRV controls include a dehumidistat function which can be
set to achieve a dehumidification effect from the HRV dur-
ing the winter heating season. High-speed ventilation will
be initiated upon exceeding the dehumidistat set point.
Once the humidity in the house is reduced, the HRV will re-
vert back to its previous setting.
It is recommended that the unit be operated for the first few
days without use of the dehumidistat function to observe if
a further dehumidification effect will be required. The dehu-
midistat operates in % of RH (relative humidity) with 80 be-
ing high and 20 being low. Set the Dehumidistat to 80% RH
to disable. If, after a few days, further dehumidification is
required (the house is too humid), set the humidity level to
a lower setting. Comfortable humidity levels range be-
tween 30 and 50% RH, depending on personal preference.
The dehumidistat should be off for all seasons except the
heating season (set to 80% RH).
Synchronizing the Humidity Setting
The optional wall controls (Y2171 and Y2172) have a fea-
ture that allows the controls to be synchronized with other
humidity instruments in the home. To synchronize:
1. Turn off the control with the ON/OFF button.
2. Simultaneously press and release the ON/OFF button
and the 20/40/60 minute high−speed override button.
3. Use the Up/Down arrow buttons to adjust the Humidity
Indicator on the display screen to the number of de-
grees difference between your humidity measuring
device. Minus is indicated by flashing.
4. Press the MODE button.
Dehumidistat Disable Feature
The new auto dehumidistat function prevents unwanted
use of the dehumidistat when outdoor temperature ex-
ceeds 59ºF (15ºC).
The dehumidistat function will be disabled if the outdoor
temperature exceeds 59ºF (15ºC) for a 24−hour period.
The dehumidistat function will be re-enabled if the unit is
unplugged for 3 minutes or if the outdoor temperature
drops below 59ºF (15ºC) for a 24-hour period. The dehumi-
distat disable feature is permanently enabled in the ERV
unit.

4-Mode Descriptions
The two optional digital controls have 4 operational modes
and 2 or 5 speeds on each mode to adjust indoor ventila-
tion levels. Experiment with the ventilation levels in the
home to evaluate the best amount of ventilation to suit the
homeowner needs and preferences.
1. Continuous Ventilation Mode (VENT)
This is the most popular mode since it provides contin-
uous ventilation within the home. You may, for exam-
ple, select Continuous Ventilation at high speed for
high household activity levels, or Continuous Ventila-
tion at low speed for lower activity levels.
2. 20 minutes ON, 40 minutes OFF Mode (20/40)
This mode provides 20 minutes of ventilation each
hour. Use this mode in low speed for low household ac-
tivity levels or if the home is unoccupied.
3. 20 minutes ON, 40 minutes, Recirculation Mode*
(20/40/RECIRC)
This mode provides 20 minutes of ventilation each
hour and 40 minutes of recirculated air. Use this mode
if the HRV is NOT connected to a forced air system
(forced air system already circulates household air).
4. Continuous Recirculation Mode* (RECIRC)
This mode recirculates household air (no ventilation).
Use this mode if the HRV is NOT connected to a forced
air system.

Installation Methods
There are three methods of installation for the HRV/ERV:
SSimplified installation (Page 14)
SPartially dedicated installation (Page 15)
SFully dedicated installation (Page 16)
Sizing the Ductwork
The installer must ensure all ductwork is sized and
installed as designed to ensure the system will perform as
intended.
The amount of air (cfm) that the HRV/ERV unit will deliver
is directly related to the total external static pressure
(E.S.P.) of the system. Static pressure is a measure of re-
sistance imposed on the blower by length of ductwork plus
the number of fittings used in the ductwork.
Installing Ducting Between the HRV/ERV Unit
and 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 90º 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
it should be the aluminum foil type.
Galvanized (rigid) ducting from the HRV/ERV to the living
areas in the house is recommended whenever possible al-
though flexible duct can be used in moderation, if neces-
sary.
A short length (approximately 12" [300mm]) of non-metal-
lic 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.
IMPORTANT
Applications such as greenhouses, atriums, swim-
ming pools, saunas, etc. have unique ventilation re-
quirements which should be addressed with an iso-
lated ventilation system.

Installation MethodsSimplified (Return/Return)
Simplified Installation (Return/Return Method)
The simplified method draws stale air from the cold air re-
turn duct of the air handler/furnace and introduces an
equal amount of fresh air farther downstream into the cold
air return (see figures 8 and 9).
Key points
SThe HRV/ERV unit must be balanced.
SIt is mandatory (to eliminate recirculation) that either
the furnace blower run continuously or HRV/ERV unit
operation be interlocked with the furnace blower.
SThe duct configuration may change depending on the
HRV/ERV model. See specifications for your unit.
SCheck local codes and authority having jurisdiction for
acceptance. Figure 8. Simplified Installation (Return/Return)
Installation Notes
SSee unit specifications for exact port locations.
SUnit is normally balanced on HIGH speed with the furnace blower ON.
SA minimum separation of 40 inches (1m) is recommended between the two direct connections.
SThe exhaust air connection should be upstream of the supply air connection to prevent exhausting any fresh air.
SWeatherhood arrangement is for drawing purposes only. Six feet (2m) minimum separation is recommended. The
weatherhood must be 18" (460mm) above grade minimum.
SThe airflow must be confirmed on site using the balancing procedures found in this manual.

Partially Dedicated Installation
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 (see figures 10
and 11).
Figure 10. Partially Dedicated System
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 on page 12.)
The air handler/furnace blower should be running when the
HRV is operating to evenly distribute the fresh air through-
out the house. (Refer to Interlocking the HRV to an Air
Handler/Furnace Blower on page 24.)

Fully Dedicated Installation
The fully dedicated installation draws stale air from specific
points in the house and delivers fresh air to specific loca-
tions of the house. This system is not connected to an air
handler/furnace (see figures 12 and 13).
Figure 12. Fully Dedicated System
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" on page 12.)
Fresh air ducts should be installed to all bedrooms and liv-
ing areas, excluding bathrooms, kitchen, and utility areas.
Grilles should be located high on a wall or in ceiling loca-
tions. Grilles that diffuse the air comfortably are recom-
mended. (Refer to Grilles on page 19.) 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 inline duct heaters are available for mounting in
the supply air duct work to add heat if required.

Installing HRV/ERV unit
WARNING
Electric Shock Hazard.
Can cause injury or death.
Disconnect all remote electrical power
supplies before servicing. Unit may
have multiple power supplies.
Unit must be connected to a grounded
power supply in accordance with na-
tional and local codes.
CAUTION
Potential Water Damage.
Condensation can accumulate and cause water
damage to equipment, finished surfaces and struc-
tures.
Unit must be installed level to ensure proper con-
densation drainage.
If possible, avoid installing units above areas or
equipment that are sensitive to water damage.
Otherwise, the use of an auxiliary drain pan under
the installation is recommended.
Connect condensate drains in accordance with na-
tional and local codes.
P−Trap and tubing must be located below the HRV
door with a minimum of ¼" per foot downward slope
away from unit.
Location Selection
It is recommended that the HRV/ERV unit be located in a
conditioned space where it will be possible to conveniently
service the unit. Typically the HRV/ERV unit would be lo-
cated in the mechanical room or an area close to the out-
side wall where the weather hoods will be mounted. If a
basement area is not convenient or does not exist, a utility
or laundry room may be used.
Attic installations are not normally recommended for HRV/
ERV units due to:
Sthe complexity of work to install,
Sfreezing conditions in the attic,
Sdifficulty of access for service and cleaning.
Sufficient clearance at the front of the access door is re-
quired for servicing the air filters and core. A minimum of
25" (635mm) clearance is recommended so the door can
be opened. Four PVC reinforced polyester hanging straps
are provided for hanging the HRV/ERV unit from the base-
ment floor joists.
Consideration should be given to unforeseen events
such as a clogged drain line or water intrusion due to
rain. This may cause water to form below the HRV/
ERV. The use of an auxiliary drain pan under the
installation should be considered.
CAUTION
Potential poor air quality results.
HRV3−195 & HRV3−300 defrost cycles will draw in air
surrounding the defrost intake opening and distrib-
ute throughout the home.
Avoid locating defrost intake duct/opening in an
area that may draw in undesirable temperatures or
poor air quality. This is often achieved by drawing in
air from a conditioned living space through a dedi-
cated duct installed on the defrost intake fitting.

Installing Drain Connection (HRV unit only)
During a defrost cycle, the HRV unit may produce some
condensation. This water should flow into a nearby drain,
or be taken away by a condensate pump.
CAUTION
Potential Freeze Conditions leading to Water Dam-
age.
Condensation can accumulate and cause water
damage to equipment, finished surfaces and struc-
tures.
Do not install HRV or route condensate drain lines
in areas that can be subjected to freezing.
Potential Water Damage.
Unit must be installed level to ensure proper con-
densation drainage. Avoid installing units above
areas or equipment that are sensitive to water dam-
age.
Connect condensate drains in accordance with na-
tional and local codes.
P−Trap and tubing must be located below the HRV
door with a minimum of ¼" per foot downward slope
away from unit.
The HRV cabinet has prepunched holes for the drain (see
figure 15). Insert the drain spout and its O−ring seal through

Figure 15. P" Trap (HRV unit only)
Construct a P−Trap using the plastic tee connector (see
Drain Hose Plumbing, figure 15). Cut two lengths of hose
and connect each piece to an end of the ˆT˜ fitting, then
connect the other ends to the two drain spouts. Position
the "T" fitting to point upward, and connect the drain line.
Tape or fasten base to avoid any kinks. This creates a
ˆtrap˜ which will hold some condensate and prevent odors
from being drawn up the hose and into the fresh air supply
of the HRV unit. (Fig. 15 also shows Drain Pipe Plumbing.)
NOTE − Secondary drain pan may be required to protect
from condensate leakage, especially when unit is installed
above living space.
Installing Grilles
Use adjustable grilles or diffusers to balance the flow rates
into and out of various rooms. The grilles should not be ad-
justed after balancing the unit.
Install grilles or diffusers high on the wall or in the ceiling.
Kitchen grilles must never be connected to a range hood.
Install grilles at least 4 feet (1.2 m) horizontally away from
the stove.
Install field-supplied balancing dampers external to the
unit to balance the amount of stale air being exhausted
with the amount of fresh air being brought into the house.
(Refer to Air Flow Balancing on page 28.)
CAUTION
Potential equipment malfunction or damage.
May require repairs and/or void warranty.
Do not install intake grille within 4 feet (1.2 m) of a
kitchen stove or cooking surface that emit cooking
vapors.
Kitchen Grille
The kitchen grille includes a
removable grease filter. Most
building codes require that
kitchen grilles be equipped
with a washable grease filter.

Installing Weatherhoods
Installing Ducting from Weatherhoods to the
(HRV/ERV) Unit
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 in-
take 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 minimize airflow restriction, the flexible insulated duct
that connects the two outside weatherhoods to the
HRV/ERV unit should be stretched tightly and be as short
as possible.
Twisting or folding the duct will severely restrict airflow.
Hard (rigid) ducting which has been sealed and insulated
should be used for runs over 10’ (3.3m). Refer to local
building codes.
Intake Weatherhood Requirements
Observe the following when installing the intake weather-
hood:
1. Should be located upstream (if there are prevailing
winds)
2. At least 6’ (2m) from the exhaust weatherhood
3. At least 6’ (2m) away from dryer vents and furnace ex-
haust (medium or high efficiency furnaces)
4. A minimum of at least 6’ (2m) from driveways, oil fill
pipes, gas meters, or garbage containers
5. At least 18" (457mm) above the ground, or above the
depth of expected snow accumulation
6. At least 3’ (1m) from the corner of the building
7. DO NOT locate in a garage, attic or crawl space
8. AFTER installing the weatherhood, its outside perime-
ter must be sealed with exterior caulking
Exhaust Weatherhood Requirements
Observe the following when installing the exhaust
weatherhood:
1. At least 6’ (2m) from the ventilation air intake
2. At least 18" (457mm) above ground or above the depth
