How much ventilation is needed?
During seasons when windows and doors are closed (win-
ter and summer, if air conditioned) the ERV/HRV 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.
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 lev-
els 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.

Description
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.
20 Minutes
On, 40
Minutes
Recirculation*
This mode ventilates for 20 minutes
and circulates the household air for
40 minutes each hour. This mode is
not applicable if your HRV is con-
nected to a forced air system. This
mode is useful when “Continuous
Ventilation” mode is providing too
much ventilation.
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 mode is useful if
“Continuous Ventilation” mode is
providing too much ventilation.
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 unoccu-
pied. This mode is useful if “20 Min-
utes On, 40 Minutes Standby” mode
is providing too much ventilation.
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.
Continuous
Low Fan
Speed
This mode will operate the fan in
low speed continuously at the se-
lected operating mode (Ventilation
or Recirculation).

Description
Continuous
High Fan
Speed
This mode will operate the fan in
high speed continuously at the se-
lected operating mode (Ventilation
or Recirculation). This mode is HI
useful when occupancy or activity
levels in the home is high for an
extended period of time.
Recirculation
Recirculates existing household air
without introducing fresh air. Recir-
culation 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.
* This mode of operation is only available on the Digital 5 Speed / 5 Mode
Control (Y8250).
