Refrigerant circuit:

On cooling only and heat pumps indoor units, each circuit
includes as standard :

- Thermostatic expansion valve

- Filter drier

Each refrigerant circuit is pressure and leak tested with a
Hydrogen/Nitrogen mixture, and vacuumed before being charged
with nitrogen. All units are then subjected to a complete functional
and operational run test to guarantee perfect sealing before
leaving the factory.

R410A refrigerant

Effi cient systems such as AIRCOOLAIR are designed around
R410A refrigerant to achieve the best performances.

- Energy effi cient refrigerant thanks with pressure drop in the
pipes: Higher evaporating pressure and lower condensing
pressure improve compressor EER & COP.

- R410A compressors have a better isentropic effi ciency.

- Environmentally friendly refrigerant: It contains No Chlorine
(ODP = 0).

Free cooling: economizer for Split Unit

Indoor sections are supplied with one or two double-inlet
centrifugal fans. Double fans are fi tted with a common axle with
one motor. Equipped with adjustable drive, variable pulley and
belt, to set up the right airfl ow on site.

Dynamic and alternate defrost

Defrost is necessary to ensure effi cient operation of heat
pumps in winter. The unit starts defrost cycle when the outside
temperature is below a set temperature and repeat the defrost
cycles periodically . It results sometimes in starting an expensive
defrost cycle when it is very cold outside but very dry, or too
warm, in other words when the coil is not frozen.

- Dynamic defrost is Lennox’ answers to unnecessary defrost
cycles. Dynamic defrost detects icing of the coil by monitoring
the difference between refrigerant and outside temperature
and starts the defrost cycle only when required. Under certain
conditions a rooftop unit equipped with this built in dynamic
defrost feature can run several hours in heat pump mode
without starting any defrost cycle. Dynamic defrost can save
up to 15% on annual energy consumption.

- Alternate defrost saves energy by reducing the need for

auxiliary heating during defrost cycles. With Alternate defrost
when one circuit starts a defrost cycle the other circuit is
running in heat pump at full capacity to minimize the need
for auxiliary heating.

Morning anticipation and dynamic set point for Split
Unit :

The unit can be programmed to switch-on in the morning to reach
the occupied zone temperature set point just in time.
Dynamic set point can be used in summer to offset the ambient
temperature set point according to the outdoor temperature.
This is to avoid large temperature difference between indoor and
outdoor. The indoor temperature set point would then increase
with the outdoor temperature improving comfort and saving large
amount of energy

Scheduling / Time zone Management:

In order to ensure the unit perfectly matches the requirements of
the most diffi cult applications in terms of occupation and varying
internal loads, the CLIMATIC 60 offers now up to 7 time zones
per day (Z0 to Z6) adjustable by steps of 10 minutes. Each time
zone can be programmed to follow one of four possible operating
modes: A,B,C & D

GENERAL DESCRIPTION

CONTROL

The new generation of microprocessor based control, CLIMA TIC
60 equip the AIRCOOLAIR range.
It inherits more than 20 years of technology and fi eld operating
experience from its predecessors Climatic control platforms.
CLIMATIC 60 controller intelligently improves effi ciency and
helps set up and service operations to guarantee long lasting
performance.

CLIMA TIC 60 is designed to provide the best energy effi ciency
throughout unit’s life cycle while ensuring reliable and consistent
operation with user friendly interfaces.
This new controller constantly monitors more machine parameters
than ever to improve unit operation and maximize effi ciency
and reliability

The PI algorithm of the CLIMATIC 60 controls the supply air
temperature and a temperature difference between supply and
return. It is able to optimize the refrigeration circuit operation to
match perfectly the required cooling or heating load maximizing
effi ciency and comfort.

COMFORT AND AIR QUALITY OF SPLIT UNIT

It will also improve reliability with features such as compressor
operating limits monitoring, (High and Low refrigerant pressure
and temperature now measured and displayed on DS60 and
Bus) refrigerant leak detection or compressor operating time
equalization and protection against excessive short cycling.

Faults and alarms

CLIMA TIC 60 manages more than 90 different faults and alarms
codes and can store the last 32 with time and date. The stored
faults and alarms can then be displayed on the DS60 and on
the communication bus with the full text detail.

Intelligent air quality management

With accurate percentage of fresh air the dampers are regularly
calibrated to introduce just the required amount of fresh air in the
building to reduce annual energy consumption. The fresh air ratio
can also be controlled using the indoor CO2 level as an input.

Intelligent heating priority optimization

This feature allows the user to program the priority between the
different heating elements (thermodynamic, electric heaters or
auxiliary heating). This is particularly interesting on units with
electrical pre-heaters. This feature maximizes energy effi ciency
by optimizing heat pump operation depending on the outdoor
temperature.

Filtration

Two fi ltration levels are available. The standard equipment is G4
washable and refi llable fi lters with metallic frame. This type of
confi guration allows to extend the lifecycle of fi lters and reduce
the cost of replacement, changing only the media. G4 pre-fi lter/
F7 fi lter is optional.

Fire Insulation

Air treatment sections are insulated with M1 material: this insures
that the insulation doesn’t burn and doesn’t create toxic smoke.
M0 insulation is in option mechanically fi tted.

require «neutral» connection. It is powered by 400 V , 3 phases,
50 Hz except size 20S

Circuit breakers

To improve the safety of the AIRCOOLAIR and extend its life,
circuit breakers protect against over-loading, over intensity and
a disconnected supply phase. Maintenance is also improved as
there is no requirement to change fuses. The electrical panel is
manufactured in accordance with EN60204-1 (1998) electrical
directive.

Adjustable ventilation for Split Unit

Airfl ow and external static pressure characteristics are adjusted
in the factory to deliver the right pulley and belt to be the nearest
to the site needs. However, once on site, the real characteristics
of ventilation requirement might be slightly different than theory
measured on drawings: therefore, AIRCOOLAIR Split unit
is delivered as standard with adjustable pulley opened. This
remains the possibility to adjust the airfl ow accurately at the
commissioning and fi nd the perfect airfl ow for the site comfort
and system effi ciency.

Refrigerant pressure reading :

No need to access to refrigerant pressure gauges.
Refrigerant pressures and superheat on each circuit can be read
directly on the service display DS60 or a BMS as all units are
equipped with high and low pressure transducers and refrigerant
suction temperature probes

FRESH AIR OPTIONS

Economizer

020S - 045D 055D - 140D

Free cooling is provided through the use of fresh air when it’s
appropriate rather than cooling the return air. Using an economizer
is the easiest and most effi cient way to modulate fresh volumes
and reduce running costs for air conditioning application, as well
as improving air quality. Fully controlled by the CLIMATIC, it is
also able to ensure that minimum fresh air is provided in line
with Indoor Air Quality Regulations. Economizer operates using
a «sensible» control. It is possible to prevent the economizer
from supplying air below a certain temperature (adjustable set
point, 10°C as default).

On sizes 20S to 45D, the economizer is factory fi tted on unit
and tested prior to shipment. It includes 2 dampers operating
from a 24V actuator.

On sizes 55D to 140D, the economizer is delivered as a separate
module that can be installed as monobloc on site. It includes 3
dampers operating from 3x 24V actuators

Exhaust module

The exhaust fans eliminate the air overpressure in the room. It

Return Module

The RETURN FAN module is necessary when the return duct
circuit creates high pressure drops. It offers available static
pressure up to 250-300 Pa.
It includes a separate casing to be connected to the economizer
casing with the ductworks.
The return module drives the opening and closure of the 3
dampers regarding the amount of fresh air introduced.

eDrive: available in Non Standard Request

eDrive, direct transmission on return fan and supply fan :
variable speed fans adjust airfl ow rate to the exact needs
and during unoccupied period. This feature saves up to 30%
annual energy consumption and reduces maintenance costs.
CLIMATIC manages air fl ow rate passing through the unit
following 3 possible strategies.
eDrive control strategies can be changed with each time zone
in occupied or unoccupied mode. Whatever the control stra­tegy, soft starter is still available to infl ate fl exible ducts and
reduce inrush current during fan starts.

- Standard mode : Constant air fl ow rate

- Dead Zone mode : Reduced air fl ow rate in “dead zone”.

- Part Load mode : Variable air fl ow rate during part load and
dead zone.

020S - 045D 055D - 140D

is driven by the Climatic controller.
On sizes 20S to 45D, it is delivered as a separate module that

can be connected to the return duct.
On sizes 55D to 140D, this exhaust fan is in built in the

economizer casing

INDOOR AIR QUALITY OPTIONS

High fi ltration level - G4 pre-fi lter / F7 fi ltration

G4 pre-fi lter 50 mm / F7 fi lter 100 mm are both in metallic refi llable
frames. This confi guration allows extending the lifecycle of fi lters
and reducing the cost of replacement, changing only the media.
100 mm fi lters have been selected also to reduce the energy
consumption due to:

- lower pressure drop especially when the fi lters start being
dirty.

- decrease of the replacement frequency.

Analog dirty fi lter and fan control :

This analog pressure sensor analyses the clogging of the fi lters
to inform the user and to allow preventive replacement of the
fi lters that will decrease the energy consumption and increase
the air quality.

Air Quality sensor :

This function allows to adapt the minimum fresh air to the building
occupancy. It measures the CO2 level and adjust the fresh air
volume accordingly.
Indoor air quality is controlled from the CLIMA TIC main controller.
A VOC (V olatile Organic Component) sensor detects the amount
of CO2 in the ambient air between 0 and 2000PPM. The VOC
sensor sends a proportional signal (0-20mA) to the CLIMATIC
controller which will then modulate the fresh air damper.

AUXILIARY HEATERS OPTIONS

Stepped or modulating Electrical heaters

Additional or instead of heat pumps, Lennox offers many auxiliary
heaters on every air-to-air units. This helps to adapt to local
climate requirement, local regulation preferences and applications
variable heating needs.

Standard, Medium and High heating power capacity are available
on each unit size
High electrical heater is also available as modulating instead
of 2-stage heater.
The performances of this option are available in auxiliary heaters
selection: page 44

The electric heater comprises of shielded resistance heaters,
which are smooth anticorrosion tubes 8 W/cm² capacity.
3 security elements are insuring permanent controls of the heaters:

- 2 high temperature limit controls offer overload protection. An
automatic reset safety thermostat is set at 75°C – a manual
reset safety thermostat is set at 105 °C; both located at less
than 150 mm over electric heaters. This is provided as a
standard feature on the electric heater, with the electric power
supply cables made of reticulated silicon rubber, resistant to
temperatures up to 200°C.

- an air pressure differential controls the fan activity and dis­connects the electrical heater in case of critical airfl ow

- dual contactor are insuring safe redundancy in case of failure
of one dry contact

Modulating Hot water coil :

This modulating heater is equipped with a 3 way valve offering
accurate comfort and electronic adjustable antifreeze protection.
This avoids the use of glycol in most of European regions.
The hot water coils and control valves are factory fi tted in air
treatment section.
The performances of this option are available in auxiliary heaters
selection page 44.

OPTIONS

REFRIGERATION OPTIONS INSTALLATION AND SAFETY OPTIONS

Winter cooling operations down to 0 °C

This option allows the AIRCOOLAIR to operate in cooling mode
with an outside temperature down to 0°C (instead of 15°C on
the standard unit).
This is especially needed when free-cooling operation is not
possible. This function is made of condenser fan alternate start/
stop that maintains a constant condensing pressure.
This equipment is standard on heat pump versions

Winter cooling operations down to -15 °C

Unit fi tted with variable speed fans. This option also allows
cooling operation in very low outside temperature (-15°C), with
good performance on condenser fan, belt lifecycle extension
and starting peak current reduction.
Strongly recommended for applications where cooling is required
during winter.

Refrigerant pre-charged

As standard, the units are delivered with Nitrogen. With this
option, the outdoor unit is fi tted with refrigerant and equipped
with service valves option.

Active Acoustic Attenuation System with variable
speed fans

Low Noise option consists in an acoustic jackets .
Besides, with the variable speed fan include in Winter cooling
operations down to -15 °C option, the CLIMA TIC 60 controls the
fan speed limited by the Smart Acoustic System which allows
progressive adaptation of the unit to the building load while
respecting the noise level constraints and the operating limits.
The maximum sound level and the fan strategies can be adjusted
according to the schedule mode in order to benefi t from the
different modes “Auto”, “Auto Quiet” and “Quiet” operation as
well as in heating or cooling mode.
The Active Acoustic Attenuation System can be adjusted
according to the scheduling and can take different values for
each schedule mode.

Main disconnect switch

Main disconnect switch is lockable to make a safe access to
electrical panel. It is installed on the electrical panel door of
the compressor section and controls all parts. Is also used as
emergency cut off: it is mandatory to guarantee a proper access
to this switch. Main disconnect switch is sized accordingly to the
options fi tted in the unit.

Smoke detector

Located downstream of the fi lter, the optical head of the smoke
detector can detect any type of smoke. When this occurs the
unit will stop operating, the return air damper will be fully closed
and the fresh air damper will fully open while sending an alarm
signal to the unit.
In accordance with the European norm, it is also compliant with
the French regulation on public buildings.

Compressor electrical protection

Return lock against 3 phases inversion at installation. This
protection prevents the Scroll compressor from starting and
operatint in the wrong sense: in case of the electrical phases
are wrongly connected, the compressor will not start. The
compressor electrical protection option is particularly required
when the installation of the air conditioning unit is made before
the electrical wirings.

Condenser coil guards:

The condenser coil protection grill prevents light damage to the
coil when shipping and when installed.

Coil Anticorrosion protection:

When the units are installed in potentially aggressive
environments, which can often be the case for example in coastal
environments, it is often a requirement that the coils are specially
treated to protect them against the corrosive effects. LenGuard
anti-corrosion treatment is available on indoor and outdoor units.

M0 Insulation indoor unit:

Because health and safety issue cannot be compromised,
Lennox equips its air treatment units (indoor unit) with a fi re-proof
insulation M0 that is mechanically fi tted to the unit.

Service valves

This option consists in liquid and gas service valves that isolate
the refrigerant section during maintenance. This is particularly
useful when components of the circuit have to be changed. It
reduces the time and cost of maintenance operation.

Long distance refrigerant connection

When the distance between the condensing section and the
treatment section is over 40 meters of cupper piping, this kit has
to be installed. It allows distance up to 65 meters.
