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
