What Are HRVs ?
To understand these products and
their functions, here are a few things
to remember.
Heat Recovery Ventilators (HRVs)
are recommended for colder areas of the
country that have longer heating seasons
as well as drier desert areas of the South.
Heat Recovery Ventilators are complete
whole house ventilation systems that
incorporate a supply motor and an
exhaust motor in one unit. The supply
motor draws fresh air in from the outside
and the exhaust motor pushes stale con-
taminated air out. The two air steams are separated by a heat/ ener-
gy recovery core which tempers the air making it the most comfortable solution for a
healthy indoor environment.
For information on how these units can help you save energy and lower heating or
cooling costs, read “How Do They Work”.

Heat Recovery Ventilators (HRVs)
An HRV is designed to bring a continuous sup-
ply of fresh air into a home while exhausting an
equal amount of contaminated air.HRVs use
what is called a “sensible” heat recovery core.
This special aluminum core transfers heat from
the exhaust air stream to the incoming air
stream. Fresh incoming air is tempered by the
heat that is transferred from the outgoing air so
you save on energy costs. Fantech HRVs are
equipped with automatic defrost mechanisms
so even if you live in the coldest climates you
can use your HRV all year long.

tion even in defrost mode without the need
for additional parts. An exhaust only (fan
shut down) defrost strategy is an effective
method at an affordable price.

OPERATION
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 should be maintained between (30-
60) to avoid condensation. Low speed continuous ventilation with high speed
override is recommended.
AHeat 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.
Fantech 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. Below are some examples of seasonal operation of an HRV.
NOTE: Some products may not be exactly as illustrated in the Installation, Operation and Maintenance Manual.
Fantech Inc. reserves the right to modify, at any time and without notice, any or all of its product's features, designs,
components and specifications, to maintain their technological leadership position.
Fall:
Rain and rapid temperature changes make it difficult to control the internal
humidity level and may result in condensation on the windows. A remote dehu-
midistat may help give greater control over the inside environment.
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 Intellitek series controller is
installed, the air exchanger can be set to cycle the unit on and off as desired
from that wall control. However, continuous ventilation is recommended.
Spring:
Temperatures aremoremoderate and become warmer each day. To keep the
humidity and temperature uniform, set the dehumidistat higher (if installed). You
may also switch the HRV to standby mode if desired.

MODES OF OPERATION
4
1. Continuous / Ventilation Mode
In this mode of operation both fans are operating and
exchanging air with the outside. The heat recovery ven-
tilator (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 con-
trol. 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.

4. Defrost (Fan shutdown 4 portmodels)
During the defrost sequence, the supply blower shuts
down & the exhaust blower continues to ventilate for a
preset time. The unit then returns to normal operation,
and continues cycle
3.Defrost/Recirculation Mode (5 port“R” Models)
During the defrost sequence, it's mechanism uses a
motorized damper to temporarily block the incoming
fresh air stream allowing the warm air from the home
to circulate through the HRV. The exhaust blower
shuts down & the supply blower continues to run. The
unit then returns to normal operation, and continues
cycle.
2. Intermittent / Standby Mode (SHR(D) / VHR Series
of HRV's)
The system is always on standby and operates at high
speed when activated by an optional remote control.
"Standby" should be selected if the user wishes to stop
the unit from continuous exchange. We recommend
that 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).

RTS2 Pushbutton Timer -The 20-minute remote timer is typically installed in areas where
contaminated such as moistureand odors, areproduced. Simply push the button and the HRV
will activate to high speed for 20 minutes. Up to 5 electronic timers can be installed throughout
the building at a distance of up to 500 feet (152 meters) from the HRV.
Air Quality Sensor -The wall mount Air Quality Sensor (AQS) monitors indoor air quality and
activates the override mode when carbon monoxide, formaldehyde, benzene, volatile organic
compounds and other pollutants are detected. The unit will then return to normal mode once
the air pollutants are reduced to a pre-determined lower level.
*This control is not a warning device.
MDEH2 Dehumidistat -The wall mount dehumidistat II offers the same features of the
dehumidistat I plus additional off/on control for the HRV. Dial illuminates when in override
mode.
MDEH1 Dehumidistat -The wall mount dehumidistat monitors the humidity level in the area it
is installed. When the humidity level rises above the desired set-point, the HRvV will activate to
high speed/override mode. Once the humidity level returns to desired condition, the unit will
return to the normal mode. Typically used during heating season.
*All controls are low voltage. 18 to 24 gauge wire is recommended.
OPTIONAL REMOTE CONTROLS
RTS3 Pushbutton Timer -This intermittent timer is the ideal control for those areas of the
home where excess moisture, steam and odors are created. Press the button once to energize
your HRV system to high speed for 20 minutes (green). Press the button twice and the unit
will run for 40 minutes at high speed (yellow). Press the button three times and the unit kicks
to high speed for 60 minutes (red). When time expires the unit will return to it's original
setting.
EDF1 Triple Function Wall Control-Triple-Function Wall Control makes it easy to control your
home's indoor air quality system. Press the button once to run your HRV at a continuous low
speed (green). Press the button twice and the unit will run 20 minutes on/40 minutes off
(yellow). The cycle repeats continuously. Push the button three times and the system will run
continuously on high speed (red).
To avoid window condensation:
It is not necessaryto change the humidity control
every day. Monitor the average weekly
temperature or experiment with various settings
until you find a level that is comfortable for you.
Adjust the control when needed.
NOTE:
Adehumidistat is ideal for use in energy efficient
houses where indoor humidity (during the heating
season) is higher than outdoor levels. High
humidity is a major cause of structure damage
and IAQ problems such as mold and mildew.

cated for life. They requireno maintenance.
The unit -The inside of the unit should be vacuumed
yearly. Be careful not to damage any of the mechanical
components and electrical connections.
The drain pan and drain line -Units with drain lines
should have their line and connection checked regularly.
Outside hoods -The outside hoods need to be checked
every season to make sure there are no leaves or insects
blocking the airflow. Check regularly that there are no
pollutants near the intake hood. Make sure they are clear
of any snow accumulation during the winter months.
Clean Core and Filters Every 3-6 Months. Unplugged before
doing any repairs or maintenance
a) Open access door.
b) Carefully grip ends of core and pull evenly outward. Core may
be snug, but will slide out of the channel.
c) Once removed from the cabinet remove filters.
d) Wash core in warm soapy water (do not use dishwasher).
ToInstall Clean Coreand Filters.
