Factory-installed options
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.
Thermostat options include a unit-mounted manual
changeover (MCO) or auto changeover (ACO) thermostat.
The temperature set point knob and pushbutton switches
for fan speed and cool/heat mode (MCO) selection are
conveniently located on the top. The thermostat senses the
return-air temperature. The thermostat sends the appro-
priate signal to the controller for cooling or heating mode
of operation.
Options R and S allow connection to a remote wall-
mounted thermostat. The Complete C controller requires a
heat pump thermostat. The Deluxe D controller can be
configured for heat pump or heat/cool thermostat.
Extended range is provided to insulate the coaxial coil 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).
Cabinet options include a locking control panel for
added security. Bottom or front return with left or right
hand configurations are available for ease of installation.
Available with 3 or 5 in. subbase, with or without motor-
ized damper.
Motorized fresh air damper with the unit-mounted
thermostat. Opens when LOW or HIGH fan speed selec-
tions are made from the push button switches. When
STOP or FAN ONLY selections are made the spring return
on the damper motor closes the damper. With remote
thermostat the motorized fresh air damper opens when the
fan is running.
Piping connections can be provided on either the right
or left hand side of the unit, for easy installation. Orienta-
tion is determined by facing the unit from the front side.

Automatic flow regulators include internally mounted
2.25 or 3.0 gpm per ton automatic flow regulating valves
ation.
for easier install
Two-way motorized control valve can be provided with
a copper or cupronickel heat exchanger for applications
involving open type systems or variable speed pumping.
This valve will slowly open and close in conjunction with the
compressor operation to shut off or turn on water to the
unit. Standard two-way valve performance includes coeffi-
cient of velocity (Cv) of 2.9 and maximum operating pres-
sure differential (MOPD) of 125 psi.
Mute package includes high density noise suppression
material on front, right, and left sides of compressor
compartment and 1 / -in. fiberglass insulation on all
2
insulated surfaces, for extra-quiet operation in the most
critical applications.
Deluxe D control system provides the same functions
as the Complete C while incorporating additional flexibility
and functions to include:
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 operation of fan control for
dehumidification operation.
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 appli-
cations including fan and compressor cycling, digital night
setback (NSB), mechanical night setback, water valve oper-
ation, and outside air damper operation.
Night low limit — If the unit operation is turned OFF from
either the push button switches, remote thermostat or the
energy management system, it is possible that the space
temperature could drop uncontrollably. The night low limit
feature, with Deluxe D controller, helps maintain the space
temperature at a level that is the best compromise between
energy consumption and a safe space temperature. A ther-
mostat located near the return air filter activates the blower
and compressor operation when the space temperature
falls below 50 F. When return-air temperature is raised
above 55 F the compressor and blower stop.
Override function — An override function is available for
units operating in occupied/unoccupied mode under the
