WIRING CONNECTIONS
IMPORTANT WARNING
Any wiring modification on the CLIMATIC™50 must be done by Lennox technician or employees having valid
electrical qualification and authorisation.
For any modification of wiring on the 24V supply or on 4-20mA sensor, check the polarity prior to apply
the power. Wrong polarity may cause serious damage and destroy the pLAN network. Lennox will not
accept liability for damage caused by wrong power connection or any wiring modification done by
people without valid training and qualifications.
Any external connection with the unit, using 24Vac voltage should not exceed a length of more than 30m.
It concerns external contacts connected to Climatic™50 on logical inputs. Over 30 m, the installer must
interface this information with relays or converters.
In any case, the 24Vac control voltage must not be used to drive external function with Climatic™50
logical output.
WARNING: Separate as much as possible probes, displays, logical input cables from power cables with strong inductive load, in
order to avoid possible electromagnetic perturbations.

Standard connection is:
Ferrite
BM50 on connector 'C’,
DC50 on connector ‘A’ or ‘C’,
DS50 on connector ‘B’.
Jumpers:
"Displays" are supplied directly by the Climatic board with 30Vdc. Take particular care at the path this 30V is taking when several
boards are being used.
J14 and J15 can switch on or off the direct current from the power supply:
J14 and J15 set between1-2:
Connectors ‘A’, ‘B’, ‘C’ and screw connector ‘SC’ are in parallel. Power is supplied to all connectors.
J14 and J15 set between2-3:
Connectors ‘B’ and ‘C’ are powered in parallel but connector ‘A’ and screw connector SC are not.
Displays connected to these ports will not be powered.
If J14 and J15 are set in different positions the "terminal connection board" DT50 DOES NOT WORK and so the
connected displays do not operate.
Ferrites Protection of Display
To avoid the appearance of disturbances HF, which can cause the destruction of components in the displays, you must equip the
cable with a ferrite when installing it (provided by Lennox).

EVAPORATOR PUMP(S) MANAGMENT
Function
Ensure the presence of a flow rate of heat transfer fluid in the evaporator heat exchanger.
Description
Seven types of control rules can be set. They are defined using the menu (3711) on the DS50 Service Display.
If (3711) = “Started“: Climactic™50 does not control the pumps,
If (3711) = “Stopped”: Pumps are stopped,
If (3711) = “P1 Only”: Climactic™50 controls only the pump N°1,
If (3711) = “P2 Only”: Climactic™50 controls only the pump N°2,
If (3711) = “P1-N_P2-R”: Climactic™50 controls handles both pumps with N°1 as standard and N° 2 as backup,
If (3711) = “P2-N_P1-R”: Climactic™50 controls handles both pumps with N°2 as standard and N° 1 as backup,
If (3711) = “Clock”: Climactic™50 controls handles both pumps equalizing running times and switching from one
pump to the other every Tuesday at 02h00 am.
In the case of single pumps, the pump N°‘k’ is running if all of the following conditions are met:
Ö At least one ON/OFF of circuit “n” is ON,
Ö Unit remote ON/OFF is ON *,
Ö Unit is NOT in the unoccupied zone*,
Ö Set point (3711) is not set to “Stopped”,
Ö Configuration (3821) is not set to “No”,
Ö Pump has been stopped for 1 minute or is already running,
Ö There isn’t electrical fault on the pump,
Ö There is a « flow rate » fault.
(*) These conditions are ignored if the outdoor temperature is below set point (3341) + 1°C and if the outlet water
temperature is below set point (3321) +1°C, in order to prevent the water from freezing.
A pump can be controlled by the Climactic™50 even if the network pump is not handled by the refrigeration unit
(electrically speaking).
In the case where the customer is handling the control of his own pump, the following procedure must be
followed:
ƒ Start the pump at least 1 minute before validating the remote ON/OFF switch operation.
ƒ Switch off the pump 2 minutes at least after the remote ON/OFF switch has gone to 0.
In the case of double pumps, the pump N°’k’ is running if all of the following conditions are met:
Ö The conditions detailed above for the single pump must be met for the pump ‘k’,
Ö In the case of forced operation, pump N°’k’ is running (set point (3711) is set to “P1 Only” for pump N°1 and
“P2 Only” for Pump N°2)
Ö When running « Standard/Backup » operation, pump N°’k’ has priority (Set point (3711) set to
“P1-N_P2-R” for Pump N°1 and “P2-N_P1-R” for pump N°2).
Ö In the case of “equalized run time” operation the running time of pump N°’k’ is the smallest.
In case of a fault on a pump when the set point (3711) is set to « P1-N_P2-R », « P2-N_P1-R » or « Clock », the
second pump, if available, will automatically start.
NOTE: Climactic™50 stops the pumps only 2 minutes at least after the request to switch the whole unit OFF has
been given, in order to prevent any risks of freezing the evaporator heat exchanger.

THERMOSTAT – Control principle
Function
Adjust and hold the fluid outlet temperature as close as possible to the set point, by controlling the number of
compressor stages depending on the thermal load of the system.
Description
Climactic™50 controller calculates constantly the required capacity to reach the temperature set point.
This variable is called “CAPACITY FACTOR” (CF) and its value can vary from 0 to 100%.
It is directly linked to the number of control stages of the unit.
Thus for a unit with 4 stages of regulation, the CF will start and stop a stage with the following values: ~0-25-50-75100%.
It then evolves following the principles detailed in the diagram below (case of a chiller):

In order to anticipate, the reference point is recalculated each time the difference between air temperature and set
point reach a minimum or a maximum.
In any cases, for a chiller, if the low water temperature limit is reached, compressors are stopped.
Moreover, the set point (3325) limits the power factor in cooling mode, and the set point (3335) set point limits the
power factor in heating mode. The control calculates the difference between the Inlet and Outlet water temperature.
Example:
For a unit with 2x2 scroll compressors, with four steps (25.0% by stage); if the (3326) set point is equal to 5°C, then
5 / 4 = 1.25°C, and if the chilled water Inlet temperature set point is equals to 7°C the power factor can go up to the
25.0% (1 stage) only if T°Inlet ≥ (SP_Water (3321) + 1.25K).
Then the power factor can go up to the 50.0% (2 stages) only if T°Inlet ≥ (SP_Water (3321) + 2.5K), (2x1.25K), and
so…

COMPRESSORS
Function
From a outlet temperature need (Capacity Factor) the compressors are started and stopped with a determined
sequence in order to minimize the anti short cycle protection effect and to equalize the operating time.
Description
Compressors Start/Stop sequences.
This sequence is set by the memorized compressor operating time and it also includes the other compressors backup function, if they are not available. However, for circuits with tandem compressors (small + big), the compressor
management favours the unit performance, COP, rather than the compressor operating time balance.
The compressor starts if all the following conditions are satisfied:
•
The remote ON/OFF switch for the complete unit is ON,
•
The ON/OFF control for the considered circuit is ON,
•
The water circulation flow has been detected for at least 1 minute,
•
The unit, the circuit and the compressor don’t have major faults,
•
The control requires the starting of the compressor,
•
The compressor has the lowest operating time among the stand by compressors,
•
The compressor has been switch OFF for at least 1 minute,
•
The compressor has not been brought into service for at least 5 minutes.
Each compressor state can be checked on the following menus: (2312), (2322), (2332), (2342), (2352), and (2362).
To check the operating time of each compressor use menus: (2318), (2328), (2338), (2348), (2358), and (2368).
To reset an operating time counter, put the DS50 cursor on the line and press the key `ENTER during 20sec.
Compressor operation authorization
The Climactic™50 may limit the operation of the compressors according to the outdoor temperature. As well, the
user may choose to limit the operation of the compressors by using contacts or the DS50 settings.
Outdoor temperature
All compressors are automatically disabled if all the following conditions are satisfied:
• The unit is equipped with thermostatic expansion valve,
• The unit is operating in cooling mode,
•
The outside temperature is below 5.0°C.
High pressure unloading
•
High pressure unloading consists in reducing the circuit capacity by stopping one or more compressors on the
concerning circuit before the high pressure reaches its limits in order to keep a partial capacity with high outdoor
temperature.
DS50 Settings
•
Stop one or several compressors of the unit, defined by the settings (3411), (3412) of the terminal DS50. (If the
compressor number is not displayed, the compressor is disabled).

DEFROST – (REVERSIBLE UNITS ONLY)
Function
Avoid the evaporator icing (external coil) in heat pump operation in winter time.
Description
To avoid the icing of the external air exchanger in winter operation, it is necessary to reverse the refrigerant cycle on
a regular basis to de-ice by heating the exchanger. A defrost is activated when the air temperature is under a set
point (3622).
When defrost is demanded, the sequence is as following:
1. Stop compressors and fans,
2. Reverse the 4 way valve,
3. Start compressors,
4. When the condensing pressure reaches 35 bars or if the compressors are operating for more than 6
minutes, the compressors are stopped,
5. Start fans at full speed during 1minute in order to dry the exchanger (The time is adjustable with the set
point (3625)).
6. Reverse the 4 way valve,
7. End of defrost.
Two different types of defrost demand are possible:
• Dynamic defrost: set point (3621) = Dynamic,
• Cycling defrost: set point (3621) = Cyclic.
Cycling defrost
The unit will start a cyclic defrost in heating mode under a regular period of time defined by the set point (3624).
Dynamic defrost
This allows the unit to start the defrost cycle only when required. This is achieved through the measurement of the
temperature difference between the coil and the outdoor. The defrost will be initiated shortly after the ClimaticTM50
has located the largest gradient in the curve.

SUPPLEMENT OF HEATING (REVERSIBLE UNITS ONLY)
Function
The heat pump units allows to control supplementary of heating capacity, providing dry contacts to connect up to 4*
electrical heaters on the expansion board (BE50) driven by the Climactic™50. The supplement of heating stages
are started and stopped with a pre-determined order.
(*) See the complete description below.
Description
Operation priority, Compressors / Additional heating
From factory setting, in heat pump mode, Climatic™50 starts compressors first and then if necessary, starts
additional heating.
The electrical heaters start if all the following conditions are satisfied:
• The remote ON/OFF switch for the complete unit is ON,
• The ON/OFF control for the considered circuit is ON,
• The unit is running in heating mode,
• The water circulation flow has been detected for at least 1 minute,
• The unit doesn’t have major faults,
• The unit is at full load (all available compressors are running) for at least 2 minutes.
The pre-determined order for activation of the electrical heater uses a LIFO structure (Last In First Out). The rotation
is based on the principle that the first electrical heater which will be stopped is the one which have started the last
one. So the pre-determined order to switch OFF to ON is always the same: Heater N°1, 2, 3, (4) and the switching
to OFF is: Heater N° (4), 3, 2, 1.
The control of the electrical heaters uses the same principle as the thermostat control for the compressors.
NOTE: The fourth electrical heater (4) is use in backup mode, which means only when none of the compressors is
running.

CONDENSING FANS CONTROL
Function
Maintain the condensing pressure as stable as possible in order to increase the unit performances, while avoiding
excessive cycling.
Description
Identical to the complete machine control logic, the Climactic™50 aims is to reach and hold the high pressure set
point. The Climactic™50 control the fan thanks to the inverter ATV21, which constitutes a frequency speed variation
driver.
Operation
The unit uses one fan driver by circuit, except for specific size of unit which use a third one common to the two
circuits. There are two types of condensation temperature set point:
• For units using thermostatic expansion valve, the set point is defined by the setting (3616),
• For units using electronic expansion valve, the set point is automatically calculate according to the outdoor
temperature. This function offers better efficiency during operating in part load compressors.
Condensation set point for units with electronic expansion valve
• The condensing pressure is controlled by a P.I.D algorithm, which is configurable thank to the settings:
P = (3613): Proportional set point,
I = (3614): Integral set point,
D = (3615): Derivate set point.

SMART ACOUSTIC SYSTEM™
Function
The fan speed limit is controlled 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.
Description
The maximum sound level and the fan strategies can be adjusted per time zone (ZA, ZB, ZC, ZD, Inoc, BMS) on the
Climactic™50. Customer can choose between “High performance” or “Low noise” operating as well as in heating or
cooling mode.
Operation
•
The maximum sound level desired can be adjusted by the setting (3612), expressed in dBa. The minimum sound level
depends on the size of the unit and defines the maximum capacity (%) of the condensing fan allowed.
•
The Climactic™50 can manage 3 different strategies for the fan and compressors, defined by the setting (3611): NOT
USED, QUIET, QUIET++. This set point controls the fan capacity (%) and the compressors in case of condensing pressure
too high.
If (3611) = “NOT USED“, there isn’t any control of the capacity limit of the fan. The capacity range is [0;100]%.
If (3611) = “QUIET“, the Climactic™50 controls the capacity limit of the fan according to the set point (3612). In case of
condensing pressure too high, the controller unlocks the capacity limit to prevent from HP security alarm.
If (3611) = “QUIET++“, the Climactic™50 controls the capacity limit of the fan according to the set point (3612). In case
of condensing pressure too high, the controller unloads a compressor to contain the HP pressure.

FREECOOLING OPTION
Function
Ensure optimum cooling capacity though the use of free cooling, therefore reducing electrical consumption.
Description
The freecooling fans are controlled by a PID algorithm. They have a higher priority face to the compressors. Once the
freecooling is over 95.0% during 2min, the compressors are allowed to start according to the water thermostat algorithm (cf.
previous part). In case of decreasing of the freecooling capacity under 90.0%, the thermostat capacity is lock to prevent from
starting of a new step of compressors.
The freecooling is enable if the following conditions are satisfa:
•
The unit is ready (On/Off, water flow, no probe alarm, etc..),
•
The freecooling driver is operating (none alarm)
•
T°outside < (T°inlet – 3°C).

COMMUNICATION
MASTER/SLAVE
Function
Link several units in order to allow a “Master/Slave” relationship between each unit. In case of “Twins” unit (NAC 680, 760, 840,
960, 1080), the master/slave settings must be configured.
Description
Configuration of the pLan network
To configure the addresses of the cards for the pLan network, see chapter: (Configuring the pLan address of the BM50)
For the pLan network, each unit must have a different address:
Unit 1
Æ Master unit,
Units 2 to 4 Æ Slave units.
Master/Slave Modes
Several master/slave modes are available and may be configured by using set points (3913):
Cascade Twins:
All units start / stop in same time and try to reach the water capacity demand. The master unit manages the increasing of
capacity and tries to equalise the step(s) compressor(s) engaged. The decreasing of step(s) is controlled individually by each unit.
The power factor of the cooling / heating capacity is also calculated individually on each unit. In case of alarm on the unit, the water
control will continue and engage the next steps according to the availability of each unit.
Cascade Chain:
The units start in cascade (one after the other) and try to reach the water capacity demand. The master unit manages the
starting of each unit. The power factor of the cooling / heating capacity is calculated individually on each unit. In case of alarm on the
unit, the water control will continue and engage the next unit according to the availability of each unit.
Back-up Twins, Rotating Back-up Twins:
One of the units is selected in backup and is kept in standby. In case of alarm on one of the operating units, the unit in standby is
allowed to start to replace the unit with alarm. As consequence, the faulty unit is stopped and declared in standby.
In case of more than 2 units, the units running (except the unit in standby) are managed as same as “Cascade Twins” mode.
Back-up Chain, Rotating Back-up Chain:
The back-up functionality is the same as “Back-up Twins”, except that in case of more than 2 units, the units running are
managed as same as “Cascade Chain” mode.
The ClimaticTM50 manage the rotation between the units declared for the “Cascade” or “Rotating Back-up” modes every week
according to the following table.
In case of 4 units, the rotation is as follow:
Week
Week (n modulo 5)
Week (n+1 modulo 5)

BMS
Function
This is used to link a Climatic™ to a BMS network for remote control of the unit.
Description
The Climatic™ 50 can communicate using various protocols:

(3922) = 2: LNXVISION system,
(3922) = 3: MODBUS protocol,
(3922) = 4: BACNET system,
(3922) = 5: TREND system,
(3922) = 6: CAREL system,
(3922) = 7: LONWORKS system.
Tables of MODBUS, LONWORKS, BACNET & TREND addresses are given in an appendix at the end of this manual.
The identification number of each unit can be set (3921) and the communication speed is adjustable from 1200 Bauds to 19200
Bauds (3923).
(3921) Æ Address of the unit on the bus,
(3922) Æ Choice of type of protocol,
(3923) Æ Choice of communication speed.
MODBUS protocol
For this option the BM50 must be fitted with the PCO1004850 card.
This card is used to interface a BM50 with an RS485 type bus.
The card provides optically coupled isolation between the regulator and the RS485serial network.
On the Climatic™, set point (3922) = MODBUS:
Transmission Mode = RTU,
Baud Rate = set point (3923) (1200/2400/4800/9600/19200),
Word Length = 8,
Parity = NONE,
Stop Bits = 2,
Card Id = set point (3921) = (1 to 199).
LONWORKS protocol
For this option the BM50 must be fitted with the PCO10000F0 card
This card is used to interface a BM50 with a LonWorks® network by FTT-10A 78 kbs (TP/FT-10).
On the Climatic™, set point (3922) = LonWorks,
Baud Rate = set point (3923) = (4800),
Device Id = set point (3921) = (1 to 199).
‘Watchdog’ function with the Climatic™50.
The Climatic™50 automatic control system, being passive on the bus, cannot detect all communication failures with the BMS.
Therefore in the event of a communication failure, the unit will continue to function with the last settings transmitted by the BMS.
To prevent this risk from hindering correct operation of the unit, the BMS must regularly write a non-zero value in word 01h. On
its side, the Climatic™50 automatic control system decrements the value of word 01h by 5 units every 5 seconds.
The items below are not taken into account by the Climatic™50, if word 01h is equal to 0, and in this case it works with set points
programmed internally.
This function does not prevent writing of bit or word; these can always be read on the DS50 display (set to BMS mode by means
of the ‘PRG’ button)
Word 01h being available in read/write on our display, we are able to test the BMS mode manually and see the value
decrementing then returning to internal control mode.
Points affected by word 01h:
Words:
02H/03H /05H/06H,
Bits:
