PLEASE READ TH S MANUAL
BEFORE NSTALL NG UN T.
CAUTION
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.
• 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 nstallation and wiring is in
accordance with CEC, NEC, and local electrical
codes.
• 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.
•The use of an extension cord with this unit is not
recommended. f 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.

Note
Selecting the Ventilation Rate That is Right for You
The modes of operation and speeds are used to adjust your indoor ventilation rate. Experiment with the
ventilation levels in your home to evaluate the ideal amount of ventilation to suit your home and
personal preferences. Operational modes available to you will depend on the main control that is installed.
Some features and modes may be unavailable to you.
Recirculation
Recirculates existing household air without introducing fresh air. Recirculation modes (II and V) are not
applicable if your HRV is connected to a forced air system, since your forced air system already circulates the
household air. Recirculation modes are unavailable on some models.
I. Continuous Ventilation
This mode of operation provides continuous ventilation within the home. You may, for example, select
Continuous Ventilation at low speed for normal operation and increase to high speed during increased
activity levels, such as cooking and showering, etc.
II. 20 Minutes On, 40 Minutes Recirculation 20/hr 40/hr
This mode ventilates for 20 minutes and recirculates the household air every 40 minutes each hour. This
mode is not applicable if your HRV is connected to a forced air system.
III.20 Minutes On, 40 Minutes Standby 20/hr 40/hr
This mode of operation provides 20 minutes of ventilation each hour. You can use this ventilation mode at
low speed for low household activity levels or when the home is unoccupied.
IV. 10 Minutes On, 50 Minutes Standby 10/hr 50/hr
This mode of operation provides 10 minutes of ventilation each hour. You can use this ventilation mode at
low speed for low household activity levels or when the home is unoccupied. This mode is useful when
20/40 mode is providing too much ventilation.
V. Continuous Recirculation
or
This mode continuously recirculates your household air (no ventilation). This mode is not applicable if your
HRV is connected to a forced air system.
VI. Continuous Low Fan Speed LO
This mode will operate the fan in low speed continuously at the selected operating mode (Ventilation or
Recirculation).
VII. Continuous High Fan Speed HI
This mode will operate the fan in high speed continuously at the selected operating mode (Ventilation or
Recirculation). This mode is useful when occupancy in the home or activity is high for an extended period
of time.

How the Dehumidistat Works
Only the DXPL02, BC02 and BC03 controls are equipped with an adjustable Dehumidistat.
High indoor humidity levels, during the heating season, have become a problem in many well
insulated, tight homes, excessive condensation on the window 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 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 15oC
(59oF). During the heating season, the operation of the HRV may reduce indoor humidity levels
sufficiently to eliminate the need for further dehumidification. If your home requires further
dehumidification, use the Dehumidistat feature if available located on the main control. 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. Refer to the "Setting
the Dehumidistat" section of either the DXPL02, BC02 or BC03 control instructions on how to set
the Dehumidistat, depending on which control you have installed. The Dehumidistat function
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.
The DXPL02, BC02 and BC03 controls have an adjustable Dehumidistat which can be set to achieve
a further dehumidification effect from your HRV. High speed ventilation will be initiated upon
exceeding the Dehumidistat set point regardless of the mode and speed of operation. Once the
humidity in the house is reduced, the HRV will revert back to its previous setting.
We suggest operating the HRV for the first few days without use of the Dehumidistat function to
observe if a further dehumidification effect will be required. The Dehumidistat operates in % of RH
(relative humidity) with 60 being high and 20 being low. If after a few days, further
dehumidification is required (the house is still too humid), set the humidity level to a lower
amount.
The average person is comfortable between 30% and 50% RH. The Dehumidistat should be set to
off for all seasons except the heating season.
Dehumidistat Disable automatically disables the dehumidistat function on the main control when outdoor
temperatures exceed 15oC (59oF) 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 15oC (59oF) for a full 24 hour period or if the HRV is reset (unplugged for 30 seconds).

Interlocking the HRV to an Air Handler or Furnace
Blower
Connecting the HRV as illustrated will ensure the air handler/
furnace blower motor is operating whenever
the HRV is venting.
The HRV must be interlocked to the furnace/air handler with a
simplified installation (return/return installation) and should be
interlocked with a partially dedicated installation.
Setting “Standby” When Using a Main Control
The HRV will be “fully-off” when the off position is selected on the
Timers mount in standard electrical boxes
Use 3 wire 20 gauge (min.) 100 ft length (max.) low voltage wire and multiple timers individually wired back to the unit.
Caution:
Consideration should be given to competing airflows when connecting the HRV in conjunction with an air handler/furnace
blower system.
Building codes in some areas require “fully-off” 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”.
Attention/Caution
Main Control. Timers and/or other controls will not function when the HRV 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.
Operating the HRV With Dry Contact Controls
A jumper must be in place between 2 (ON) and 3 (RED) on the terminal block to activate the HRV for timers and/
or dry contact controls.
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)

Maintenance Routine
1. Inspect Exterior Hoods at Least Once a Month
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).
2. Clean Air Filters (Clean Four times a Year)
The standard filters equipped with your HRV are removable and washable.
a) Open access door and slide core out.
b) Remove filter clips if present.
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.
d) To re-assemble, place clean filter(s) (wet or dry) back into their positions against the core
and return clips to their original positions.
e) Slide core back into its original position.
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 cabinet.
c) Once removed from the cabinet remove filters.
d) Install the clean filters.
e) Install clean core in the cabinet.
Note: Core installation label on the outer end of the core.
To Install the Clean Core:
a) To reinstall the core first position the bottom of the core on the bottom support in the
cabinet.
b) Carefully align the core with the other 3 supports and fully insert the core.
c) Push on sides of core, do not push on the center.
Note: Core may appear to stick out from the cabinet approximately 1/8 in (3 mm). This is
designed this way so that the access door will fit tight against the core.
Do not use cleaning solutions for the HRV core
Soak and rinse the HRV core in warm soapy water
Do not use bleach or chlorine
Do not use a pressure washer on the HRV core
Do not place the HRV core in a dishwasher
