Cupronickel heat exchangers
are available for higher
corrosion protection for applications such as open tower,
geothermal, etc. Consult the water quality guidelines for
proper application and selection of this option.
Deluxe D control system
provides the same functions
as the Complete C control system while incorporating
additional flexibility and functions including:
Thermostat input capabilities — Accommodate emergency
shutdown mode and night setback with override (NSB)
potential. Night setback from low temperature thermostat
with 2-hour override is initiated by a momentary signal
from the thermostat.
Compressor relay staging — Used with dual stage units
(units with 2 compressors and 2 Deluxe D controls) or in
master/slave applications.
Boilerless electric heat control system — Allows automatic
changeover to electric heat at low loop water temperature.
Intelligent reversing valve operation —
Minimizes reversing
valve operation for extended life and quiet operation.
Thermostat type select (Y, O or Y, W) —
Provides ability to
work and select heat pump or heat/cool thermostats (Y, W).
Reversing valve signal select (O or B) — Provides selection
for heat pump O/B thermostats.
Dehumidistat input —
Provides fan control for dehumidifi-
cation operation.
Multiple units on one thermostat/wall sensor —
Provides
communication for up to three heat pumps on one
thermostat.
Boilerless changeover temperature — Provides selection of
boilerless changeover temperature set point.
Accessory relays — Allow configuration for multiple appli-
cations including fan and compressor cycling, digital night
setback (NSB), mechanical night setback, water valve oper-
ation, and outside air damper operation.
E-Coated airside coil
is available for highly corrosive
environments. This is an excellent option for coastal areas,
marine applications or other areas in which corrosion may
be an issue.
High-static blower
is available in all sizes for the
50RHC,RVC units. This option specifically increases air-
flow at various static pressure conditions, providing even
more flexibility to Carrier’s high blower performance
offered by the standard models.
Modulating reheat
diverts condenser water through a
water-to-air coil that is placed after the evaporator coil.
The modulating reheat valve automatically adjusts reheat
capacity based upon leaving-air temperature and loop
entering-water temperature to provide 100% reheat and
neutral supply air to the space. The modulating reheat
option is only available on 50RVC018-036 and
50RVC042-060.
PremierLink™ controller
is compatible with the Carrier
Comfort Network® (CCN) and other building automation
systems (BAS). This control allows users the access and
ability to change factory-defined settings, thus expanding
the function of the standard unit.
Sound attenuation package (mute package)
is avail-
able for applications that require especially low noise lev-
els. With this option, a double application of sound attenu-
ating material is applied to the internal divider, side panels,
top and bottom panels. Sound attenuating material is also
added to the fan housing. Spring isolation is added to the
compressor mounting. The mute package in combination
with standard unit noise reduction features (i.e., as men-
tioned previously) provide sound levels and noise reduction
to the highest degree.
