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) thermostat selec-
tion are conveniently located on the top. The thermostat
senses the return-air temperature and sends the appropri-
ate 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. See the
50KQL Control Options Table.
Extended range is provided to insulate the coaxial coil to
prevent condensation, and therefore potential dripping
problems, in applications where entering water tempera-
ture 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.
Cabinets are available with 3 or 5 in. subbase, with or with-
out motorized damper.
Motorized fresh air damper can be provided with the
unit-mounted thermostat. The damper opens when LOW
or HIGH fan speed selections are made from the push but-
ton 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/ton automatic flow regulating valves for
ation.
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 Cv of
2.9 and maximum operating pressure differential (MOPD)
of 125 psi.
Mute package includes high density noise suppression
material on front, right, and left sides of compressor
1
compartment and / -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 control system while incorporating
additional flexibility and functions to include the following.
See the 50KQL Control Options Table.
Thermostat input capabilities accommodate emergency
shutdown mode and night setback (NSB) with override
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
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.
Night low limit with Deluxe D controller, helps maintain
the space temperature at a level that is the best compro-
mise between energy consumption and a safe space tem-
perature. 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 tempera-
ture could drop uncontrollably. The thermostat is located
near the return air filter activates the blower and compres-
sor operation when the space temperature falls below
