pre-occupancy purge, economizer
controls and early morning warm-up.
This controller has a 38.4K baud
communications capability and is com-
patible with
Comfort
Link™ Controls,
CCN (Carrier Comfort Network®)
and ComfortVIEW™ Software. The
Scrolling Marquee and Navigator are
optional tools that can be used for pro-
gramming and monitoring the unit for
optimal performance. The addition of
the Carrier CO
2
sensor in the condi-
tioned space provides ASHRAE
(American Society of Heating,
Refrigeration, and Air Conditioning
Engineers) 62-99 compliance and
Demand Control Ventilation.
The PremierLink™ peer-to-peer,
internet ready, communicating control
is designed specifically for Constant
Volume and Variable Volume and
Temperature applications. This com-
prehensive controls system allows all
Carrier 3 to 25 ton rooftops to be
daisy chained together on a roof to
create a fully functional HVAC (heat-
ing, ventilation, and air conditioning)
automation system.
Indoor-air quality begins with
Carrier rooftops
Sloped condensate pans minimize
biological growth in rooftop units in ac-
cordance with ASHRAE Standard 62.
Two-inch filters with optional dirty
filter indicator switch provide for great-
er particle reduction in the return air.
The face-split evaporator coils improve
the dehumidification capability of
standard units, maximize building
humidity control.
Optional proportional reacting
CO
2
sensor is available with the
EconoMi$er IV outdoor air damper
option/accessory to aid the IAQ bene-
fits.
Energy$Recycler — the IAQ
solution for today’s “tight”
buildings
Indoor-air quality (IAQ) generally refers
to the level of pollutants inside a build-
ing. These pollutants include cigarette
smoke, carbon dioxide exhaled by
occupants, radon gas, car exhaust,
paint fumes, and odors.
Concern over increased indoor air
pollutants has been spurred by several
issues: 1) changes in new building con-
struction methods and retrofit of older
buildings have reduced air infiltration
rates; 2) Synthetic materials release air-
borne particles, odors, and chemicals;
and 3) HVAC (heating, ventilation, and
air conditioning) systems that bring in
minimal fresh air.
In 1989, IAQ concerns caused
ASHRAE to recommend increased
ventilation for all public buildings. Sim-
ply introducing fresh air into a building,
however, is not always practical or cost
effective. Additional ventilation can
overload HVAC systems and increase
energy costs.
Carrier’s 62AQ Energy$Recycler
unit solves this dilemma by providing
increased fresh air while keeping in-
creased costs to a minimum. In addi-
tion, the Energy$Recycler helps re-
duce humidity levels, which helps to
prevent deterioration of building mate-
rials and retards the growth of mold
and mildew.
The 62AQ Energy$Recycler unit
provides the best solution to retaining
the energy-conserving benefits of to-
day’s tighter building construction
while improving indoor-air quality.
The Energy$Recycler can be inte-
grally mounted in the size 004-012
units or free standing for all units.
