Winter:
Humidity control is very important during the winter
months. This is when problems will be most apparent
since condensation on the windows will often occur. The
colder the outside temperature, the greater the risk of
condensation in the home. The average relative humidity

A Heat Recovery Ventilator (HRV) is designed to bring fresh air into a building while exhausting an equal amount of stale air. During the winter
months, the incoming cold fresh air is warmed by utilizing the heat recovered from the stale air before it is exhausted to the outdoors. During
summer months when the indoor space is air conditioned, the HRV will help in cooling the incoming fresh air with the stale air that is being
exhausted.

Our HRV’s are designed to run continuous or on intermittent, giving the homeowner complete control over their air quality. Continuous low speed
ventilation is recommended, which will help eliminate carbon dioxide, voc’s and other gases as well as freshen up the home. Intermittent high
speed ventilation can be obtained through a variety of optional remote controls found in this manual (page 13 ). Below are some examples of sea-
sonal operation of an HRV.

Spring:
Temperatures are more moderate and become
warmer each day. To keep the humidity and tem-
perature uniform, set the dehumidistat higher (if
installed). You may also switch the HRV to standby
mode if desired.

Summer:
The air is sometimes hot and humid. To stop the warm
humid air from entering, set the dehumidistat at its
highest level. If the digital control is installed, the air
exchanger can be set to cycle the unit on and off as
desired from that wall control. However, continuous ven-
tilation is recommended.

Fall:
Rain and rapid temperature changes make it diffi-
cult to control the internal humidity level and may
result in condensation on the windows. A remote
dehumidistat may help give greater control over the
inside environment.

The entire line of Heat Recovery comes equipped with our new electronic uni-control board which offers a wide variety of features making it the ulti-
mate ventilation control system. Our engineers have used the latest technology to provide solid, trouble free operation under any conditions.
mate ventilation control system. Our engineers have used the latest technology to provide solid, trouble free operation under any conditions.
The uni-control board offers stand alone operating capabilities as well as an exclusive 2 wire communication to most external controls. The trouble-
free optional controls include: two different rotary dial dehumidistats, an air quality sensor (3 wire communication required), a 15 minute remote
push-button timer, as well as the most sophisticated line of remote wall mounted controls, the digital control.

An on-board diagnostic LED helps find problems quickly and efficiently. For example the LED can be used to signal a broken or shorted electronic
wall control wire. Electronic air temperature probe gives this board accurate readings in order to minimize unnecessary defrost operation, and the
on-board jumpers provide the user with the option of adjusting defrost time and sequence to optimize performance under abnormal conditions. The

The automatic defrost cycle con-
sists of a fan shutdown. When the
supply air stream temperature
goes below -5°C (23°F), the sup-
ply motor shuts down and the exhaust motor goes into high speed.
Ambient air is passed through the unit for a period of 5 minutes. The
supply motor will then re-start and run at the preset speed. The
exhaust motor will also slow down to the preset speed, and the unit
will operate in the run cycle for 25 minutes. This fan shutdown
defrost cycle continues until the supply air stream rises above 0°C
(32°F).

lator (HRV) constantly exchanges the
air at the rate you select, either at low or medium speed, and switches
to high speed when activated by an optional remote control. The "Low"
and "Med" fan speed selection will cause the unit to operate in continuous
exchange mode at an exchange rate of 35% and 50% maximum airflow
rating respectively. Continuous mode is recommended, since pollutants
are slowly but constantly being generated in your house.

the "Standby" mode only be used if your system is equipped with an
optional external control, in which case, the unit would activate to
"High" fan speed, until the control is satisfied and then return to
standby (off).

of a damper defrost which allows air
to recirculate throughout the unit &
home. When the supply air stream
temperature goes below -5°C (23°F), the exhaust motor shuts down, the
supply motor goes to high speed, and a damper closes the supply, open-
ing a 5th collar. The ambient air is then recirculated through the unit &
home for a period of 5 minutes. The unit will then resume normal opera-
tion for a time period of 25 minutes. This damper defrost cycle continues
until the supply air stream rises above 0°C (32°F). The recirculation fea-
ture can be obtained with the use of an optional digital control.
