The CO
2
Sensor Family Expands!
Honeywell Fresh Air Economizer
Systems automatically sense
when the outside air is right to
provide free cooling as a first stage
of air conditioning. In addition, they
dramatically reduce over-ventilation
in air conditioning AND heating
modes to deliver 30% to over
50% energy savings depending
on climate, utility rates, particular
building design/type and
occupancy patterns.
EXCEPTIONAL DESIGN
All models include state-of-
the-art NDIR technology plus a
unique corrosion-free designed
sensing chamber. This patented
industry breakthrough combination
provides accurate and stable CO
2
readings for years and avoids costly
and inconvenient re-calibration.
• Patented gold-plated sensing
chamber to eliminate a primary
source of “drift”
• Automatic Background Calibration
(ABC) to re-establish outdoor ambient
concentration levels
SUPERIOR PERFORMANCE
• Calibration interval: 5 years
• Sensor life expectancy: 15 years
• Annual drift: 20 ppm
• Approved by California Energy
Commission for compliance with
Title 24 ventilation standards
APPLICATION VERSATILITY
• Honeywell Fresh Air Economizer
Systems featuring demand control
ventilation (DCV) for retail stores,
offices, schools, restaurants, theaters,
auditoriums, museums and other
“variable occupancy” applications
• HVAC building management system
input for monitoring ventilation rates,
indication of occupancy, clogged
filter/inoperable ventilation component
alert, smoke/fire advance warning
• Food manufacturing and storage:
mushrooms, flower growers and
nurseries for CO
2
level control;
dairy ventilation and agricultural
animal confinement; breweries
and restaurants/pubs
BOTTOM LINE
Honeywell Economizers with
CO
2
sensors:
• Triple your year-round savings
over “cooling only” economizing
• Deliver 5 to 10 times the savings
compared to conventional temperature
economizer changeover
