Guide specifications (cont)
4. The standard Complete C control electronic
control system shall interface with a heat pump
(Y,O) wall
electronic). The control system microprocessor
board shall be specifically designed to protect
against building electrical system noise contami-
nation, EMI, and RFI interference. The control
system shall have the following features:
a. 50 va transformer.
b. Performance Monitor (PM). The PM warns
when the heat pump is running inefficiently.
c. Anti-short cycle time delay on compressor
operation time delay shall be 5 minutes
minimum.
d. Random start on power up mode.
e. Low voltage protection.
f. High voltage protection.
g. Unit shutdown on high or low refrigerant
pressures.
h. Unit shutdown on low water temperature.
i. Water coil freeze protection (selectable for
water or antifreeze).
j. Air coil freeze protection (check filter
switch).
k. Condensate overflow shutdown.
l. Option to reset unit at thermostat or discon-
nect. Fault type shall be retained in memory
if reset at thermostat.
m. Automatic intelligent reset. Unit shall auto-
matically reset 5 minutes after trip if the fault
has cleared. Should a fault reoccur 3 times
sequentially then permanent lockout will
occur.
n. Ability to defeat time delays for servicing.
o. Light-emitting diodes (LEDs) to indicate high
pressure, low pressure, low voltage, high
voltage, air/water freeze protection, conden-
sate overflow and control status.
p. The low-pressure switch SHALL NOT be
monitored for the first 90 seconds after a
compressor start command to prevent nui-
sance safety trips.
q. Remote fault type indication at thermostat.
r. Selectable 24-v or pilot duty dry contact
alarm output.
s. 24-v output to cycle a motorized water valve
with compressor contactor.
t. Electric heat output to control two stages of
electric heat.
u. Service test mode for troubleshooting and
service.

c. E-Coated Airside Coil:
Provides
coastal areas, marine applications or other
areas in which corrosion may be an issue.
d. High-Static Blower:
Provides increased airflow at various static
pressure conditions. Available in all sizes for
50RHC,RVC units.
e. Modulating Reheat Option:
Unit shall include a water-to-air coil placed
after the evaporator coil.
f. Carrier PremierLink™ Controller:
This optional control will function with CCN
and ComfortVIEW™ software. It shall also
be compatible with ComfortLink™ control-
lers. It shall be ASHRAE 62-99 compliant
and Internet ready. It shall accept a CO
sensor in the conditioned space and be
Demand Control Ventilation (DCV) ready.
The communication rate must be 38.4K or
faster. It shall include an integrated econo-
mizer controller.
