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. Your Lifebreath MAX Series HRV main control has 5 modes of operation and 5
speeds on each mode.
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
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
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
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
This mode continuously recirculates your household air (no ventilation). This mode is not applicable if your
HRV is connected to a forced air system.
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.
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 ensure the
proper grounding of the unit.
