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.
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
attenuating material is applied, access panels are double
dampened with
1
/
2
-in. thick density fiberglass insulation,
which is applied to the basepan, and a unique application
of special dampening material is applied to the curved
portion of the blower. The mute package in combination
with standard unit noise reduction features (i.e., as
mentioned previously) provides sound levels and noise
reduction to the highest degree.
Extended range units have an insulated coaxial coil
and insulated refrigerant and water piping to prevent
condensation, and therefore potential dripping problems,
in applications where the entering water temperature is
below the normal operating range (less than 60 F). Units
are capable of operating with an entering water tempera-
ture range of 20 to 120 F.
Water circuit options provide internally mounted 2.5 or
3.0 gpm per ton automatic flow regulating valves for easier
installation.
Two-way motorized control valve can be provided for
applications involving open type systems or variable speed
pumping. This valve will slowly open and close in conjunc-
tion with the compressor operation to shut off or turn on
water to the unit.
WSHP Open multiple protocol controller is a proac-
tive controller capable of communicating BACnet, Mod-
bus, N2, and LON (with a separate card) protocols. The
controller is designed to allow users access and ability to
change and configure multiple settings and features includ-
ing indoor air quality (IAQ), waterside economizer controls,
etc.
Deluxe D control system provides the same functions
as the Complete C control system while incorporating
additional flexibility and functions to include:
Thermostat input capabilities
accommodate emergency shut-
down mode and night setback with override potential. Night
setback from low temperature thermostat with 2-hour over-
ride is initiated by a momentary signal from the thermostat.
Compressor relay staging
is 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.
The IdealHumidity™ system
provides operation of fan con-
trol for dehumidification operation (units with ECM motor
have input on the ECM board; optional Deluxe D board is
not required).
Multiple units on one thermostat/wall sensor
provides for
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 applica-
tions including fan and compressor cycling, digital night
setback (NSB), mechanical night setback, water valve oper-
ation, and outside air damper operation.
PremierLink™ controller is compatible with the Carrier
Comfort Network
®
(CCN) and other building automation
systems (BAS). This control is designed to allow users the
access and ability to change factory-defined settings thus
expanding the function of the standard unit.
LONMark compliant controller contains the factory-
loaded Aquazone™ water source heat pump application for
an interoperable control solution.
Permanent split capacitor (high static) blower motors
enable the 50P1 units to increase performance levels in
high-static applications.
Field-installed accessories
Aquazone™ system control panel includes a prepro-
grammed, easy to use, Carrier Comfort Controller set up
for a WSHP system.
• Panel coordinates and monitors loop water temperature
and all water side ancillary equipment.
