GENERAL DESCRIPTION
DESCRIPTION SPECIFIC TO HEAT RECOVERY
UNIT (DOUBLE PATH) FXK
Part of the FLEXY range, the FLEXY FX is an air/air heat pump
rooftop optimising applications using a high volume of fresh air
by recovering some of the energy from the exhaust air. Asystem
of 4 motorised dampers and 2 centrifugal fans (supply/exhaust)
allow full modulation of the fresh air + exhaust air mix, which
means that the room is never under or over-pressurised and a
perfect pressure balance is achieved. This is ideal for cinemas
or any application where the fresh air requirement is important.
Although the energy saving capability, providing lower running
costs is the main feature of the FX, our customers also appre-
ciate the fact that the unit can be fully ducted (supply, exhaust,
fresh air and condenser fan air), and can therefore be located
inside the building.
Cinema owners appreciate the fact that FX perfectly controls
the pressure inside the building with the 4 damper system .
Adjustable grids and pressure taps allow very accurate balancing
of the system. This ensures, there is no risk of doors opening
due to pressure differences. FX has been designed to maintain
a constant supply air temperature, which is achieved using a
multiple number of circuit/compressor, special sensor and control
algorythm on our CLIMATIC 50.
Available in heat pump version only with R410a, the FX has a
range of capacity from 25 to 170 kW. Numerous options enable
this very flexible rooftop to be adapted to every application. A
100% fresh air option extends the application of the FX down
to -10°C outside air.
LIFE CYCLE COST
STANDARD FEATURES
Scroll compressors / Refrigeration Circuits / R410 A for
maximum efficiency
Scroll compressors with R410A are used on the FLEXY FX for
maximum efficiency and reliability, having overload protection.
Refrigerant circuits include compressors with crankcase heaters,
condenser coils and direct-drive and evaporator coil, expansion
valves, filter dryers, high and low pressure switches, full refrigerant
charge. In addition you will find check valves, defrost control,
reversing valve on FLEXY FX heat pump models.
Specific circuiting for heat pump operation optimised on Lennox
laboratory.
Thermostatic Expansion Valves
As it is important that the units operate as efficiently as possible
and achieve maximum performance at any running conditions,
the thermostatic expansion valves optimize the superheat of
the rooftop and, therefore, its overall performance efficiency.

GENERAL DESCRIPTION
Alternate defrost
Because, this new rooftop has been designed to reduce life cycle
cost, the alternate defrost is a standard feature.
When one circuit is in defrost the other is still running in heat-
pump mode reducing the use of costly electric heater.
This unique feature on the market place comfort the FLEXY FX
as leader in terms of low life cycle cost.
Dynamic defrost (Under patent)
FLEXY FX is featuring the «dynamic defrost» concept.
In general rooftop start defrost cycle when the outside temperature
is bellow a certain value and repeat the cycle periodically.
This results sometimes in starting an expensive defrost cycle
when it is very cold outside but very dry, in other words when the
coil is not frozen.
After many tests in the Lennox laboratory, it was found that it is
possible to exactly know if the coil is frozen, by analyzing the tem-
perature difference between the coil and the outside temperature.
With this built-in feature of the CLIMATIC 50, Lennox insures to
start a defrost cycle only when necessary, hence saving energy.
EASY TO INSTALL AND SERVICE
STANDARD FEATURES
Light unit
FLEXY FX has been designed to be as light as possible to avoid
constraints.
PLUG and PLAY Unit
All options are factory installed on the unit, which means that they
are ready for use on installation, ensuring that the time spent
on site is minimised, reducing the installation effort, which can
result in cost savings.
Bottom entry (through the base) for electrical power and Hot
Water lines are available as standard.
FLEXY FX should be powered by 400 V, 3phases, 50 Hz.(no
neutral needed).
Circuit breakers
To improve the safety of the FLEXY FX and extend its life, cir-
cuit 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.
Numbered wires
All wires and connectors are numbered as shown on the electrical
drawing to facilitate maintenance and diagnostic.
Variable Pulley
For cases where the actual external static pressure or air flow
on a particular project is different from what is specified on an
order, LENNOX has enhanced the FLEXYFXrooftop by providing
an adjustable pulley. The installer can easily and quickly adjust
the air flow within a 20% window without moving the mounted
fan motors. This variable pulley provides flexibility and peace of
mind during commissioning.
EU4 / G4 grade - Disposable Filters
Ensuring easy service and maintenance. On start-up we recom-
mend that you change the throwaway filters for replaceable
washable filters, with metal frames.

OPTIONAL
Anti-Corrosion 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 .
After extensive testing, Lennox has chosen to use Thermoguard
anticorrosion cleaning for the FLEXY FX. The results of Thermo-
guard ® on saline test were so good, that coil can be guaranteed
against corrosion during 3 years (provided regular maintenance
is performed).
Thermoguard® treatment is available on Condensing coil, evapo-
rator coil and hot water coil.
(*) see corrosion LENNOX policy.
GENERAL DESCRIPTION

INDOOR AIR QUALITY AND ENVIRONMENT
FRIENDLY
STANDARD FEATURES
Quiet FLEXY FX
LENNOX believes that an innovating and environment friendly
rooftop should be quiet. Even without the Low Noise option, the
FLEXY FX is a reference on the market for standard low level of
noise.
INDOOR AIR QUALITY DOES MATTER
Fire proof (M0) insulation
Because, for LENNOX, health and safety issues cannot be com-
promised, in all rooftops fire insulation (M0 fire Class) is fitted as
standard. 65 kg/m3insulation is mechanically fitted to the unit.
This feature improves the safety of the rooftop against fire, as the
specification suggests, the insulation will not burn and smoke will
not be generated.
Edges of insulation are protected to perfectly seal the Rockwool.
Drain Pan
The underside of the unit is insulated to prevent from condensation.
The bent drain traps are shipped in a kit form. Drain pan is sloped
to prevent stagnation of water.
It slides out and can be easily cleaned, preventing growth of
bacteria in the drain pan.
GENERAL DESCRIPTION
Accurate percentage of fresh air (under patent)
Because a fresh air damper curve is not linear, it is not accurate
to assume that the percentage of opening of the damper is equal
to the percentage of fresh air entering the building.
However, this linear control of a damper is by far the most used
in the industry.
With Indoor air quality and running cost of a building being more
important to our customer, Lennox wanted to pilot the % of fresh
air more accurately.
The CLIMATIC 50 can now periodically recalibrate the dampers,
by calculating the real percentage of fresh air entering the building
for the each different positions of the damper.
This recalibration is achieved using the return air sensor, the
outdoor sensor and supply air sensor. When all heating or cooling
elements are off, the percentage of fresh air actually entering the
rooftop is the result of the following equation :
"%Fresh Air" =
"SupplyAirtemperature" - "Return Air Temperature"
"Fresh air Temperature " - "Return Air Temperature"
For example, CLIMATIC 50 would accurately adjust the damper
position to get 20% fresh air and not 30% or 10%.
Therefore, this feature either saves a lot of energy cost by not
bringing more fresh air than needed or makes sure that air quality
is at the expected level.
This allows CLIMATIC 50 to send an alarm when damper can not
be calibrated (faulty damper)
Specific case of high pressure drop in the return air duct:
The problem becomes even more critical, when the return air duct
pressure drop is greater than 50 Pa.
In this case, due to the difficulty of the return air to go back to the
rooftop, it is usual to have a lot more fresh air entering the building
than wanted, resulting in high running cost.
OPTIONAL
Indoor Air Quality Sensor
Indoor air quality is controlled from the CLIMATIC 50 boards. A
VOC (Volatile Organic Component) sensor will detect the amount
of CO2 in the air between 0 and 2000PPM. (This obviously varies
depending upon space occupancy levels). The VOC sensor will
then send a proportional signal (0-20mA) to the CLIMATIC 50
controller which will then modulate the fresh air damper.
Double skin 25 mm :
To prevent bacteria development on porous surface Lennox pro-
vides double skin panels option. This double skin panels give a
smooth inside the unit and allow an easy cleaning of the panel.

are smooth stainless steel tubes 6 W/cm2capacity.
High temperature limit control offers overload protection and is
set to 90°C and located at less than 150mm after electric heaters.
This is provided as a standard feature on the electric heater, with
the electric power supply cables made of reticulated silicon rub-
ber, resistant to temperatures up to 200°C. For any rooftop unit
size, three sizes of electric heater are available, S (standard), M
(Medium) and H (high).

Capacity can be limited electronically to an exact value through
the CLIMATIC 50. To reduce installation time and insure reliability,
electric heaters are always factory fitted, fully wired and tested,
prior to shipment.shipment.
Hot Water Coil
Hot water coils offer fully modulating control through the use of
a 3 way valve. The hot water coil, connections and valves are all
tested at pressure of 15 bars. Frost protection is provided by forcing
the opening the 3 way valve when supply temperature from hot
water coil falls below 8°C and by stopping the outdoor fan when
that supply temperature falls below 6°C. In addition to that, the 3
way valve is also opened at 10% value if the outdoor temperature
falls below an adjustable value.
Hot water coils are always factory fitted, wired and fully tested,
prior to shipment.
Hot water coil includes automatic purge system.

CONTROL
OPTIONAL
Advance control pack (control of humidity and enthalpy
control on economizer)
Where a higher level of controllability is required to make the
FLEXY FX even more flexible, LENNOX have compiled a pack
that includes two advanced control features.
-»Enthalpy control on economiser».
Software and its sensors will ensure that the economiser does
not use 100% fresh air if the outside air has a higher enthalpy
than the return air. This feature is relevant in regions where the
relative humidity is high or when the desired room air condition
is very dry.
- «Humidity control» software and its sensors, are able to ana-
lyze dry and wet bulb temperatures, and therefore can control a
dehumidification algorithm. This will dehumidify the air in cooling
mode as it passes through the coil, then reheating it with either
electric heater or hot water coil. If there is a need to humidify the
air, a proportional signal is now available to control a humidifier
that will be provided by the customer.
DC 50 : Comfort
Display
This is a remote control-
ler for non-technical
customer. It has been
wanted to aesthetically
fit inside a room and be
very easy to use. It can
be installed at maximum
500 meters from the unit.
This graphical display gives information such as running mode
of the unit, status of the fan, set point, % of fresh air, outside air
temperature.
Customer can change the scheduling of the different time zone,
can modify temperature set point and % of fresh air for each zone.
Customer can also override the scheduling in either changing the
set point for 3 hours or in forcing the rooftop to unoccupied mode
for 1 to 7 days. ON/OFF key is also available.
DC50 Comfort display shows faults number when rooftop is in the
failure mode. Customer can reset fault thanks to a combination
of keys.
Time and day of the rooftop can be seen and modified easily
through the DC50.
DM 50 : Multi rooftop Display
The DM 50 display has the exact same features of the DC50, but
it can manage up to 12 rooftops on a single Bus. On a multirooftop
site it makes the installation less expensive because, not only
because of DM50 price, but because only one bus-wire has to be
connected down to the DM50.
DS 50 : Service Display
This service display controller directly plugs on the unit.
This allows service personal to set up to 207 settings, read up
to 188 variables, up to 45 faults and read the history of the last
32 faults.
This controller has been designed to be very user friendly, with 6
different keys, a 4 lines display and this controller includes scrolling
menus and true language (no codes). It will be in English or another
alternate language. (12 different languages are available today)
TCB (Thermostat Control Board)
This board has been developed for any customer who wants
to take over the control of the unit. With 6 logical inputs (Com-
pressor stage 1 and stage 2, heating step 1 and 2, change-over
compressor and fan), this board will replace the control algorithm.
However CLIMATIC 50 controller will stay in charge of all safety
algorithm, defrost operation or free cooling operation. All Input is
volt free contact.
This is the perfect board, to have FLEXY FX rooftop managed by
a zoning system, a universal thermostat or even a BMS system.
Communication interface / Modbus interface

per rooftop.
This board is a well a modbus interface, which is needed for
anyone who would like a BMS system to talk to the FLEXY FX with
«Modbus protocol» with RS485. No other hardware than this board
is required to have modbus dialog. One board required per rooftop.
This board is required when ADALINK is used.
LonTalk® interface
This board is a LonTalk® interface, which is needed for anyone
who would like a BMS system to talk to the FLEXY FX with «Lon
protocol» with FTT10. No other hardware than this board is required
to have LonTalk® dialog. One board required per rooftop.
