Tranquility

27™ (TT) Series

ClimateMaster: Smart. Responsible. Comfortable.

The Tranquility

27™ Series has abundant features and ultra

high efﬁ ciency.

Application Flexibility

• Five Capacities 026, 038, 049, 064, and 072.

• Extended range operation (20-120°F EWT) and ﬂ ow rates as

low as 1.5 gpm per ton.

• Vertical packages with either true right or true left return

air options.

• Internally trapped condensate drain.

•

Variable speed ECM fan motor adapts to various duct systems.

• Internal electric heat unit (optional) designed for easy

ﬁ eld installation.

• Circuit breaker protected loop and hot water generator pumps.

• Field selectable freeze protection setting for well or loop.

• Standard pre-installed 2” ﬁ lter frame with 2” high performance

MERV 11 pleated air ﬁ lter.*

Operating Efﬁ ciencies

• EarthPure

HFC 410A zero ozone depletion refrigerant.

• Highest efﬁ ciencies in AHRI/ISO/ASHRAE/ANSI 13256-1 ratings

for heating COP’s, cooling EER’s with low water ﬂ ow rates.

• Two-Stage operation for ultra high efﬁ ciencies and

unsurpassed comfort.

• Operating temperature range and high efﬁ ciency allow

shorter loops.

• Optional hot water generator with internal pump generates hot

water at considerable savings.

• Rugged and highly efﬁ cient next generation Copeland

UltraTech™ scroll compressors provide ultra high efﬁ ciencies and

full capacity with reduced cycling losses.

• Oversized coaxial tube water-to-refrigerant heat exchangers

operate at low liquid pressure drop. Convoluted copper (and

optional cupronickel) water tube functions efﬁ ciently at low-ﬂ ow

rates and provides freeze-damage resistance.

• Oversized e-coated, riﬂ ed tube/lanced aluminum ﬁ n, air to

refrigerant heat exchangers provide high efﬁ ciency at low

face velocity.

• Large low RPM blowers with variable speed fan motors provide

quiet, efﬁ cient air movement with high static capability.

Service Advantages

• Removable panels - 3 for compressor 2 for air

handling compartment.

• Low proﬁ le control box grants easy access to all

internal components.

• Factory installed liquid line ﬁ lter/drier.

• Brass swivel-type water connections for quick connection and

elimination of wrenches or sealants during installation.

• Bi-directional thermal expansion valve.

• CXM control features status lights with memory for

easy diagnostics.

• Unit Performance Sentinel alerts homeowner of potential

performance issues.

• Circuit breaker protected 75VA control transformer.

• ECM control board features thermostat signal diagnostic LED’s,

airﬂ ow display LED (100 CFM per ﬂ ash), and simpliﬁ ed CFM

selection.

• Insulated divider and separate air handling/compressor compart-

ments permit service testing without air bypass.

• Fan motors have quick attach wiring harness for fast removal.

• Internal dropout blower for easy servicing.

• High and low pressure service ports on refrigerant circuit.

• Accurate refrigerant sensing freeze protection.

Factory Quality

• All units are built on our Integrated Process Control

Assembly System (IPCS). The IPCS is a unique state of the art

manufacturing system that is designed to assure quality of the

highest standards of any manufacturer in the water-source

industry. Our IPCS system:

- Veriﬁ es that the correct components are being assembled.

- Automatically performs special leak tests on all joints.

- Conducts pressure tests.

- Performs highly detailed run test unparalleled in the

HVAC industry.

- Automatically disables packaging for a “failed” unit.

- Creates computer database for future service analysis

an diagnostics from run test results.

• All units are water run-tested in all modes to insure efﬁ ciency

and reliability.

• Heavy gauge galvanized steel cabinets are epoxy powder coated

for durable and long-lasting ﬁ nish.

• All refrigerant brazing is done in a nitrogen atmosphere.

• All units are deep evacuated to less than 100 microns prior to

refrigerant charging.

• All joints are both helium and halogen leak tested to insure

annual leak rate of less than 1/4 ounce.

• Coaxial heat exchanger, refrigerant suction lines and all water

lines are fully insulated to eliminate condensation problems in low

temperature applications.

• Noise Reduction features include: double isolation mounted

compressors; insulated compressor compartment; interior cabinet

insulation using 1/2” coated glass ﬁ ber and variable speed fan.

• Safety features include: high pressure and loss of charge to

protect the compressor; condensate overﬂ ow protection; freeze

protection sensors to safeguard the coaxial heat exchanger

and air coil; hot water high-limit and low compressor discharge

temperature switch provided to shut down the hot water

generator when conditions dictate. Fault lockout enables

emergency heat and prevents compressor operation until

thermostat or circuit breaker has been reset.
