THE BENEFITS OF THE PERFECT CLIMATE® SYSTEM AND THE
FRESH AIR VENTILATION SYSTEM
We take it for granted that our homes protect us from the elements.
But, because of tighter, better quality home constructions, our indoor
environments may be exposing us to unacceptable levels of the very
things we are trying to escape—excessive heat, dryness, humidity,
toxic gases, dust and contaminants—sealed neatly in by the
weatherproofing.
So, what’s the weather 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 outdoor brings us, you can have control of indoor
conditions. Temperature, humidity levels and air quality all can 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 stresses
of work, a busy lifestyle and an increasingly polluted outdoor environ-
ment. Creating a perfect indoor climate is becoming critical to feeling
right at home.
The Honeywell Fresh Air Ventilation System removes stale, unhealthy
inside air and replaces it with a stream of fresh air.

Describing Perfection
The most convenient, most energy efficient, cleanest, healthiest and
most comfortable indoor environment possible today! Perfect climate is
achieved when the components of a home’s climate system work
together:
•optimal efficiency heating and cooling equipment.
•precise, programmable temperature control.
•high efficiency air cleaning/filtering.
•proper humidity control.
•proper ventilation and air distribution.
• whole house water filter.
•security system.
•lighting control.
•multi-zone temperature control.
Products for a
Perfect Climate® System
Heating and cooling system: This is the workhorse of your indoor
climate system. Good advice is to have your local heating/cooling
contractor tune up your system annually for comfort, safety and
economy reasons. If your heating plant is old, think about replacing it
with a modern and improved unit. Advances in product technology have
very impressively increased the efficiency of equipment. Sometimes the
improved performance will pay back much of the cost in a few short
years.

CONTROLS FOR YOUR FRESH AIR VENTILATION SYSTEM
Your Fresh Air Ventilation System controls are located on the ventilator
cabinet. See Fig. 1. There are two switches, and an indicator light
(defrost models only). In addition, control of your ventilator may be
enhanced by the use of one or more Honeywell products—Perfect
Climate Comfort Centers™, dehumidistats, timers or wall switches.
1. POWER SWITCH
This switch is located on the ventilator control panel. It is used to
control power to the entire ventilation system. When this switch is in
the Off position, the ventilation system is completely shutdown.
2. Lo-Standby-Hi SWITCH
This switch is also located on the ventilator control panel. It is used to
control the speed of the ventilation system. When the switch is in the
Lo position, the ventilator runs at reduced speed (135 cubic feet per
minute [cfm]). When the switch is in the Hi position, the ventilator
runs at full speed (230 cfm). When the switch is in the Standby
position, the ventilator is powered, but it is not operating. A signal
from a dehumidistat, a timer, or a wall switch will cause the ventilator
to run at full speed. When the signal is removed, the ventilator will
shut off and return to the Standby mode.
3. INDICATOR LIGHT (Defrost Models Only)
The indicator light is located on the ventilator control panel on
ventilators that have built-in defrost capability. The indicator light is
on when the ventilation system is in defrost.

OPERATING YOUR FRESH AIR VENTILATION SYSTEM
Step 1
Move the power switch to the On position. With this switch in the Off
position, all power to the system is removed and no system controls will
have any effect.
Step 2
Move the Lo-Standby-Hi switch to the Lo position. This setting will
provide a low ventilation rate suitable for continuous operation. When
you do not want continuous ventilation, move the switch to the Standby
position. Activating a Perfect Climate Comfort Center, a timer, a wall
switch or the sensing of high humidity by the dehumidistat will switch the
ventilator into the high speed from either the Lo or Standby position.
Move the switch to the Hi position when you want maximum ventilation.
Step 3
The Perfect Climate Comfort Center may be used to control your ventila-
tion rate. This can be done automatically by using the programmed times
or manually by pressing the Ventilate button on the keypad. See the
Perfect Climate Comfort Center™ User’s Guide (form 69-0891) for
complete instructions.
Step 4
When one or more dehumidistats are part of the control scheme, set the
dehumidistat at the desired humidity level. Generally, the dehumidistat(s)
should be located in areas, such as a bathroom, that generate excess
moisture. When a shower is used, the local humidity level will go above
the dehumidistat setpoint and the ventilation system will switch to the high
speed (maximum ventilation). The ventilation system will return to the
previous setting when the humidity drops below the setpoint.
NOTE: When there is more moisture in the outside air than the inside
air (summer time), turn off the dehumidistat(s). Moisture laden
outdoor air brought inside will not dry the house.
If your heating system has a powered humidifier, make sure the
dehumidistat is set at least ten percent relative humidity above your
humidistat. It may be necessary to lower the humidistat setting to avoid
condensation in the winter.

769-0854
Step 5
Your Fresh Air Ventilation System may utilize one or more timers. When
a high ventilation rate is desired, turn the timer to the desired number on
minutes. The Ventilator will switch from the Lo or Standby setting to the
high speed. The ventilator will return to the previous setting when the
time runs out.
Step 6
Your Fresh Air Ventilation System may utilize one or more wall switches
to provide manual control of the system. If a high ventilation rate is
desired, move a switch to the maximum position. The ventilator will run
at high speed until the switch is returned to the normal position.
NOTE: The ventilator will run at high speed if any device in the system
(Perfect Climate Comfort Center, dehumidistat, timer or wall
switch) is activated.

GETTING THE MOST FROM YOUR FRESH AIR VENTILATION
SYSTEM
Moisture Control
Continual operation of the ventilation system is recommended for
optimum reduction of indoor air pollution and control of humidity.
Increased moisture removal will always occur at maximum ventilation
rates. Use the Hi switch position when first occupying a newly built
home to remove excess moisture from new wood, plaster, cement and
other moisture absorbing construction materials. If your system is wired
to a dehumidistat, it will switch the ventilator to the high speed setting
whenever the humidity level goes above the setpoint.
NOTE: When the amount of moisture in the outside air is greater than
the amount in the inside air, running the ventilation system will
not dry the home. This will occur most often in the summer
months.
Remote Override Switch Functions
Your Fresh Air Ventilation System may incorporate one or more
remotely mounted Perfect Climate Comfort Centers™, dehumidistats,
timers or wall switches. When any of these devices are activated, the
ventilator will run at the high speed. The ventilator will return to the
previous setting when all the remote devices are deactivated. The
remote override function, in combination with the Standby setting, is
especially useful for intermittent bathroom exhaust where continuous
ventilation is not required. Continuous operation is recommended
except when the home is unoccupied, or when proper ventilation is
provided by other means such as open doors and windows.
Defrost
Ventilators designed for use in cold climates are equipped with an
automatic defrost system. The ventilator automatically detects restricted
airflow in the heat transfer core when ice starts to form and a defrost
cycle is initiated. The ventilator is closed off from the duct system, an
auxiliary heater is turned on and the air inside the ventilator is recircu-
lated continually to melt the ice that has formed. When the airflow
returns to normal, the sequence is reversed and ventilation returns to
normal. When the ventilator is in defrost, the LED indicator light on the
control panel is illuminated. Defrost time is held to a minimum by
Honeywell’s exclusive automatic defrost initiation circuit.
