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
operating at a higher static. After installation, the
compatibility of the two pieces of equipment must
be confirmed by measuring the airflows of the
Heat Recovery Ventilator (HRV) by using the
balancing procedure found in this manual.
It is always important to assess how the
operation of any HRV may interact with
vented combustion equipment (ie. Gas
Furnaces, Oil Furnaces, Wood Stoves, etc.).
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!
Application
Heat Recovery Ventilators (HRV) are designed to provide
fresh air while exhausting an equal amount of stale air.
General
The HRV is equipped with an aluminum core. The
device uses the stale air that is being exhausted to
condition the fresh air as it is being brought in.
These instructions are intended as a general guide and
do not supersede local codes in any way. Consult
authorities who have jurisdiction before installation.

Setting the Ventilation Speed
Press and release the Fan button to select LOW or HIGH fan speed. The corresponding “Indicator Light" will illuminate. If
both LO and HI indicator lights are off, the fan is OFF but will turn ON if required by the Dehumidistat or remote Timer (if
installed).
Humidity Control
Your unit will reduce indoor humidity when outdoor humidity levels are lower than indoor humidity levels. This feature is only
effective when the outdoor temperature is below 59˚F (15˚C).
Setting the Dehumidistat
Press and release the Dehumidistat button until the Dehumidistat Light is at the desired setting. After a few seconds the
Dehumidistat light will either flash or be on continuous.
A flashing light indicates the humidity level is higher than the setting and the unit is operating on high speed ventilation. A
continuous light indicates the humidity level is lower than the setting. Refer to the unit's Home Owner’s manual for instructions
on how the Dehumidistat works.
The Dehumidistat will override the current speed setting to HIGH speed.

Optional Lifebreath Dehumidistat - Part #99-DH01
Key Features
• The Dehumidistat measures the indoor humidity level and
will initiate high speed ventilation when the moisture level
in the building exceeds the set point on the control.
• Once the humidity in the building is reduced, the
HRV will
revert back to its previous setting.
• The Dehumidistat should be set to OFF for all season
except the heating season.
• Connect to 3 wire 20 gauge low voltage wire.
Humidity Control
Your HRV will produce a dehumidifying effect when outdoor
humidity levels are lower than indoor humidity levels. Never
use the Dehumidistat feature when outdoor temperatures are
above 59 F (15 C).
Note: The indoor humidity level is measured at the control.
Setting the Dehumidistat
Press and release the Dehumidistat button until the
Dehumidistat Light is at the desired setting. After 5 seconds the
Dehumidistat light will either flash or be on continuous.
A flashing light indicates the humidity level is higher than the
setting and the unit is operating on high speed ventilation. A
continuous light indicates the humidity level is lower than the
setting. Refer to the unit's Operation & Installation Manual for
