Introduction
We take it for granted that our homes will protect us from the elements, but because of
tighter, better quality home construction, our indoor environment may be exposing us
to unacceptable levels of the very things we are trying to escape. Excessive heat,
dryness, humidity, toxic gases and dust contaminants can be sealed in securely by
weatherproofing.
So what’s the forecast for indoors?
Today’s indoor forecast is stormy weather for many homeowners. But rapid clearing
and fresh breezes are just around the corner!
Feeling right at home
Unlike what the outdoors brings us, you can have control of indoor conditions.
Temperature, humidity levels and air quality can all affect physical health, mental
attitude, general comfort and energy savings. With today’s technological advances,
you can achieve a “Perfect Climate” indoors.
After all, people look to their homes as a place to escape the stress of work, a busy
lifestyle and an increasingly polluted outdoor environment. Creating a perfect indoor
climate is becoming critical to feeling right at home.
The Honeywell Perfect Window™ Fresh Air Ventilation System removes stale,
unhealthy air and replaces it with a stream of fresh air. Its powerful centrifugal blowers
bring fresh air into your home and at the same time, exhaust stale air in an equal amount.
Both incoming and outgoing airstreams pass through a energy transfer core where both
the heat and the moisture from the exhaust air are efficiently transferred to the incoming
fresh air. An air duct system supplies the fresh air brought in by the Perfect Window™
ventilator and distributes it throughout your home. Another duct draws the existing stale,
air back to the Perfect Window™ ventilator and then exhausts it outdoors.
It’s really very simple...and remarkably effective!
The Perfect Window™Fresh Air Ventilation System consists of-
1. Air Circulation FAN and Motor
Inside the casing are two fans, one for exhaust and one for fresh air supply. The
electric motor that operates the fan is 1/15 hp to 1/20 hp (depending on the ven-
tilator model) and uses the same amount of power as a 100 watt lightbulb.
2. Air Filters
There are two permanent washable air filters in your ventilator. The filters lower
the amount of dust and outside particulates entering the ventilator core and your
fresh air supply.

3. Condensate Tray and Drain
Condensation normally forms on the energy transfer core during the cold weather
(below 29°F or -3°C). Moisture can build up when the warm air from your home
comes in contact with the cold air from outside. The tray collects the moisture and
funnels it to the drain. The drain pans are made of thermoformed plastic for easy
cleaning.
4. Defrost Mechanism
The built-in defrost mechanism will remove frost which can accumulate in colder
weather (21°F [-6°C] and colder). The type of defrost mechanism used is known
as “damper style”. This consists of an electronically controlled damper door
(attached to a small electric motor) that moves to block off the outside cold air
entering the ventilator. If the outside temperature drops below 27°F (-3°C), the
defrost timer is activated. The timer activates the motor driven damper door
mechanism which temporarily moves to close off the outdoor air supply and
opens another port on the ventilator that allows warm indoor air to enter the core
to help the defrost. Approximately 4.7 minutes after the defrost cycle is acti-
vated, the timer will signal the damper to return to its original position for a
27 minute period. The defrost cycle will repeat until the outside temperature
rises above 27°F (-3°C)
.
5. Energy Transfer Core
As the exhaust and fresh air pass through opposite sides of the Energy Transfer
Core heat is transferred from the warm side to the cold side. This heat transfer
reduces the cost of conditioning the fresh outside air that is brought into your
home. In addition, moisture is transferred from the wet side to the dryer side.
This moisture transfer reduces the drying of the air inside your home that occurs
during the winter months and reduces the amount of moisture that is brought into
your home during the summer months. The core removes easily for cleaning.

6. Controls - Speed Control
Easy operation, simply rotate the Perfect Window™ ventilator fan speed control
to your desired setting.
Operating your Fresh Air Ventilation System
Changing Fan Speed
The control fan speed is conveniently located on the ventilator. The rotary fan speed
control knob can be manually set from the off (standby) position through speeds 1 to 4.
Note the fifth speed (high) is accessible only by a remote control.
Off/standby mode may be used if intermittent ventilation is desired. In the off/standby
position, the ventilator will not function until energized by a remote control, see
information below.
It is up to the individual homeowner to set their system to a speed which they find
comfortable. If you feel your house is stuffy or there is an above average occupancy
rate, you may need to increase your ventilation. In most applications a low to medium
speed setting is comfortable.
Connecting a Remote Device
Your ventilator comes equipped with a low voltage terminal strip for connection to
several optional control devices.
PERFECT CLIMATE COMFORT CENTER™ CONTROL
The Honeywell Perfect Climate Comfort Center™ unit controls your ventilator
automatically by using the programmed times or manually by pressing the Ventilate
key. See the Perfect Climate Comfort Center™ Owner’s Guide (form 69-0891) for
complete instructions.
EXTERNAL REMOTE WALL CONTROL (DEHUMIDISTAT)
The dehumidistat (connected to your ventilator) is designed to control the operation of
the ventilator fan to help keep the humidity level in your home comfortable. If an
independent humidifier is installed and set at 30% (a normal indoor winter level) then the
dehumidistat (for the ventilator) should be set at least 10% higher, in this case 40%. With
the ventilator operating on low speed and no one at home to produce humidity, the
humidifier will keep the humidity level at its setpoint. If the humidity levels rise (due to
occupant activity) above the 40% level, then the dehumidistat will automatically increase
the speed of the ventilator fan to high until the humidity level falls below 40%.
NOTE: During the winter months the air inside your home usually contains more
moisture than the outside air even though the outside relative humidity is
higher than the inside relative humidity. The energy transfer core in your ven-
tilator will transfer some of the moisture from the exhaust air stream to the
fresh air, thus slowing the drying of the air in your home. During the summer

ER150 AND ER200 Perfect Window™ FRESH AIR VENTILATION SYSTEMS
69-1188—2 6
months when the outside air contains more moisture than the inside air, the
dehumidistat should be turned off so that a call for drying of the inside air
doesn’t result in additional moisture entering your home.
TIMER
For your convenience, Honeywell provides an optional timer control that can fit a wide
variety of needs, for example, exhaust humid air from the bathroom or kitchen (see the
timer instructions for selection and part numbers).
WALL SWITCH
A wall switch can also be used to switch your ventilator fan speed to high. The fan will
run at high speed until the wall switch is turned off.
When any remote device is activated the ventilator will run at high speed. All remote
devices must be in the off position to return the fan to the speed manually selected on
the rotary fan speed control knob.
Getting the most from your Fresh Air Ventilation System
HOW MUCH VENTILATION DO I NEED?
During the seasons that your windows and doors are closed (winter and summer if you
have air conditioning), the ventilator should operate continuously when the home is
occupied, and either continuously or intermittently when not occupied.
For most installations, the ventilator will normally be set to operate continuously on low
speed with the option of going to high speed as the need arises. For example, if you
are entertaining and there is a large number of people present (some may be
smoking), the ventilator should be switched to high speed.

Maintenance Instructions for your Fresh Air Ventilation System
WARNING
Electrical Shock Hazard.
Can cause personal injury or equipment damage.
Disconnect power supply before performing maintenance.
The Perfect Window™ Fresh Air Ventilation System must be maintained on a regular
basis for best efficiency. Honeywell recommends that the ventilator be cleaned and
checked at least twice a year, preferably at the beginning of each heating and cooling
season.
Check and Clean
EXTERIOR HOODS
Exterior hoods should be inspected at least once a month. Be sure exhaust and fresh
air supply hoods are not blocked up or restricted by leaves, grass or snow. In winter, it
is especially important to make sure snow is not blocking the hoods or that frost has
not built up on the wire mesh (bird screen).

WARNING
Carbon Monoxide Hazard.
Can cause personal injury or equipment damage.
Hood blockage can cause a change of pressure in building which can lead to
possible spillage from combustible appliances.
AIR FILTERS
Air filters should be cleaned twice a year. The standard filters supplied with your
ventilator are removable and washable.
1. Open access door and slide out core. Refer to Core Maintenance section for
cleaning instructions.
2. Remove filter clip.
3. Remove filters from the core and rinse with water or a combination of soap and
water. Do not clean in a dishwasher.
4. After cleaning, place filters (wet or dry) back in their position and reattach the
retaining clip.
CORE
IMPORTANT
Do not wash the core with water or other fluids.
Clean the core twice each year using only a vacuum cleaner.
1. Open the access door and carefully grip the ends of the core and pull evenly out-
ward. The core can be snug, but it will slide out of the cabinet.
NOTE: Do not handle the fins because damage can occur.
2. When out of cabinet, remove the filters (refer to Air Filter Maintenance section).
3. When the core is dry, clean it only with a vacuum cleaner. Vacuum the filter sides
of the core by pulling any dirt back out of the core, but not by pulling dirt all the
way through the core.
4. Reinstall the clean filters.
5. Reinstall the clean core.
TO INSTALL THE CLEAN CORE:
1. First mount the bottom core guide into the bottom Core Guide Channel.
2. Mount either side core guide, followed by the other side.
3. Mount the top core guide into the top Core Guide Channel.
4. With all four corners in place and the core straight and even, push on the core
center until the core slides to the back of the cabinet.
NOTE: The core is designed to appear to protrude from the cabinet approximately
1/8 in. (3mm) so the access door fits tightly against the core.

DRAIN LINE
Clean the drain line once a year.
1. Inspect the drain line, drain spout and P trap for blockage, mold or kinks.
2. Flush with warm soapy water and replace if worn or bent, or if it can not be
cleaned.
GENERAL MAINTENANCE
Twice a year, wipe the inside of the cabinet with a damp cloth to remove dirt, bugs and
debris that can be present.
FANS
If the fans accumulate dirt, it could cause an imbalance and excessive vibration of the
ventilator. A reduction in air flow can also occur. In a newly constructed house, this
often happens within the first year due to heavy dust residue in the entire system. It
can also occur periodically, depending on the outdoor conditions. If you suspect that
service is required, please contact the ventilator installer or your local HVAC
contractor.
