are optional tools that can be used for
programming and monitoring the unit
for optimal performance. The addi-
tion of the Carrier CO
2
sensor in the
conditioned space provides ASHRAE
62-99 compliance and Demand Con-
trol Ventilation.
The PremierLink peer-to-peer, inter-
net ready, communicating control is
designed specifically for Constant Vol-
ume and Variable Volume and Temper-
ature applications. This comprehensive
controls system allows all Carrier 3 to
25 ton rooftops to be daisy chained to-
gether on a roof to create a fully func-
tional HVAC (heating, ventilation, and
air conditioning) automation system.
Carrier Apollo microproces-
sor controls add reliability,
efficiency, and simplification.
Apollo controls are designed and man-
ufactured exclusively by Carrier, the
controls can be used to actively moni-
tor and control all modes of operation.
The Apollo communicating controls
are factory-installed into the rooftop
unit control box, and come equipped
with built-in diagnostic capabilities.
Light-emitting diodes (LEDs) simplify
troubleshooting by indicating thermo-
stat commands for both stages of heat-
ing and cooling, evaporator fan opera-
tion, and economizer operation. The
Apollo communicating controls are de-
signed to work specifically with the
Carrier TEMP and VVT® (variable vol-
ume and temperature) thermostats.
The standard rooftop control system is
readily adaptable to all conventional
and programmable thermostats. In ad-
dition, units are suitable for integration
into building monitor control systems if
required. This system gives the units
the flexibility to communicate with al-
most any thermostat or building con-
trol system.
Indoor-air quality begins with
Carrier rooftops
Sloped condensate pans minimize
biological growth in rooftop units in ac-
cordance with ASHRAE (American
Society of Heating, Refrigeration, and
Air Conditioning Engineers) 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 stan-
dard units, maximize building humidity
control.
Optional proportional reacting
CO
2
sensor is available with the
EconoMi$er outdoor air damper op-
tion/accessory to aid the IAQ benefits.
Energy$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.
