CLIC and OP-CLIC: Finding the best system for
your needs
Carrier now offers two computer
services to your dealer to provide posi­
tive assurance that you’re getting the
right equipment, sized to meet your
needs at the best possible price.
Using the telephone right in your
home, your dealer can use CLIC
(Carrier Load Information Center) to
determine the heating and cooling loads
for your home, and then, by feeding the
proper information into the computer,
he can use OP-CLIC (Carrier Annual
Operating Cost Analysis Computer
Program)
to determine optimum
balance points and annual operating
costs for your system.
Quality features make
the dual-compressor
heat pump an
unbeatable value
Two rugged Carrier compressors, built to withstand
the rigorous requirements of year round heat pump duty,
provide reliable system operation. Compressors have
factory-installed overcurrent and internal overtemperature
protection Suction line accumulator protects compressors
from refrigerant floodback. Crankcase heaters prevent
dilution of oil by refrigerant when unit is off. Each compres­
sor has internal pressure relief protection. Start capacitors
and relays are standard.
Wrap-around coil in the outdoor section is designed for
maximum efficiency. All-aluminum coil provides superior
heat transfer.
High volume, low speed outdoor fan quietly discharges
air and sound up and away from surrounding homes and
neighbors. The quiet fan permits installation in a variety
of locations and delivers excellent performance without
disturbing the neighborhood.
AccuRater™ combination metering device and check valve
provides efficient refrigerant flow for the most economical
system operation.
Chronotemp defrost device removes frost from coil
when required Saves on operating costs because it’s keyed
to both time and temperature.
Liquid line low-pressure switch, combined with com­
pressor internal overloads, provides loss of charge
protection
Outdoor thermostat controls operation of second com­
pressor in response to outdoor temperature.
Signal-Loc’^“ system malfunction warning indicator
and lockout — This solid state logic circuit indicates when
a system malfunction occurs and locks out compressor(s)
for protection. The emergency heat light on the wall thermo­
stat comes on when low-pressure switch functions or when
compressor(s) fails to run on thermostat demand. The light
goes out when thermostat is satisfied or when compressor
starting is attempted by manually setting the thermostat
off, then on. If light remains on after manually resetting
thermostat, service is probably required.
Indoor fan speed controller increases indoor fan speed
during periods when second compressor is on, thereby
increasing system efficiency.
Low voltage (24 v) terminal board is provided for easy
system installation.
