Thank you for purchasing a LIFEBREATH® Heat Recovery Ventilator
(HRV). The HRV 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:
• exhausts the stale, contaminated air, found in today’s tight buildings.
• 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.
Getting to Know your RNC Series Heat Recovery Ventilator (HRV)
Your Lifebreath RNC SERIES HRV has several optional controls.
Experiment with the ventilation levels in your home to evaluate the ideal
amount of ventilation to suit your home and personal preferences.
I. CONTINUOUS VENTILATION
This mode of operation provides continuous ventilation within the home.
You may, for example, select Continuous Ventilation at a low speed (speeds
1 or 2) for normal operation and increase to a higher speed (speeds 3 to 5)
during increased activity levels, such as cooking and showering, etc.
II. 20 MINUTES ON, 40 MINUTES STANDBY
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. This feature is
unavailable on some controls.
III. 20 MINUTES ON, 40 MINUTES RECIRCULATION *
Ventilates for 20 minutes and recirculates the household air every
40 minutes each hour. This mode is non-applicable if your HRV is
connected to a forced air system (the forced air system already circulates
household air).This feature is unavailable on some controls.
IV. CONTINUOUS RECIRCULATION *
Continuously recirculates your household air (no ventilation). This mode is
non-applicable if your HRV is connected to a forced air system.This feature
is unavailable on some controls.
* If your HRV is connected to a forced air system, recirculation (modes III
and IV) is unavailable and non-applicable on all models.
RECIRCULATION - recirculates existing household air without
introducing fresh air. Recirculation Modes (III and IV) are
non-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.
Selecting the Ventilation Rate that is right for You
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 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 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.
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-E ABLE - 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).
How the Dehumidistat Works
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 - a Heat Recovery Ventilator (HRV) 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 helps to
cool the incoming fresh air with the cool exhausted stale air.
MAI TE A CE ROUTI E - Homeowner maintenance should be
performed as per "Maintenance Routine for HRV" located in the
Operation and Installation Manual.
OPTIO AL CO TROLS - A selection of Optional Controls is available
for the HRV. Refer to the Operation and Installation Manual for more
information.
OPERATIO A D I STALLATIO MA UAL - Contains
instructions and important information regarding your HRV and controls.
You can download the manual at www.lifebreath.com
.
SELF-TEST - Each time the HRV is powered/energized, the self-test
function automatically initiates. The HRV cycles through the available
speeds and tests the damper motor operation. The HRV defaults back to the
previous operational mode and speed selection after the self-test
(approximately 60 seconds in duration).
STA DBY (Speed 0) - The HRV is powered/energized and waiting for
ventilation to be initiated by either an external control (i.e. timer) or the
dehumidistat. Set the main control to speed 0 to set the HRV in standby.
TIMERS - These optional controls may be installed at specific exhaust
locations (bathrooms etc.) to initiate high speed ventilation.
