Features/Benefits (cont)
Carrier Apollo controls add
reliability, efficiency, and
simplification
The Apollo direct digital controls are
ordered as a factory-installed option.
Designed and manufactured
exclusively by Carrier, the controls can
be used to actively monitor and control
all modes of operation, as well
as to monitor evaporator-fan status,
filter status, indoor-air quality (humidity
and carbon dioxide), supply-air
temperature, and outdoor-air
temperature.
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 thermostat
commands for both stages of
heating and cooling, evaporator fan
operation, and economizer operation.
The Apollo communicating controls
are designed to work specifically with
the Carrier TEMP and VVT (variable
volume and temperature) thermostats.
The Apollo controls, combined
with Carrier thermostats, incorporate
a 5-minute recycle delay timer
between modes of operation to prevent
short cycling.
The standard rooftop control
system is readily adaptable to all conventional
and programmable thermostats.
In addition, units are suitable
for integration into building monitor
control systems if required. This system
gives the 48TJ units the flexibility to
communicate with almost any thermostat
or building control system.

Indoor-air quality begins with
Carrier rooftops
Sloped condensate pans minimize biological
growth in rooftop units in
accordance with ASHRAE (American
Society of Heating, Refrigeration,
and Air Conditioning Engineers) Standard
62. Two-in. filters with optional
dirty filter indicator switch provide for
greater particle reduction in the return
air. The face-split evaporator
coils improve the dehumidification capability
of standard units, and standard
enthalpy controls provided with
the optional or accessory (004-014)
economizers maximize building humidity
control. The 48TJ004-014 units
also have an accessory, 100% open,
two-position damper to meet all
your fresh outdoor air requirements.
