EVAPORATOR PUMP(S) MANAGEMENT
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:
At least one ON/OFF of circuit “n” is ON,
Unit remote ON/OFF is ON *,
Unit is NOT in the unoccupied zone*,
Set point (3711) is not set to “Stopped”,
Configuration (3821) is not set to “No”,
Pump has been stopped for 1 minute or is already running,
There is n’t electrical fault on the pump,
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:
Start the pump at least 1 minute before validating the remote ON/OFF switch operation.
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:
The conditions detailed above for the single pump must be met for the pump ‘k’,
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)
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).
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-
50-75-100%.
It then evolves following the principles detailed in the diagram below (case of a chiller):
+ 2K

(Start more Capacity Stages)
+ 1K
Difference between the outlet water temperature and the set point
CF DECREASES
(Removes Capacity Stages)

Water Temperature
Change rate
SLOW FAST
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 six steps (16.6% by stage); if the (3326) set point is equal to 5°C, then 5 / 6 = 0.8°C, and if the chilled water Inlet temperature set point is equals to 7°C the power factor can go up to the 16.6% (1 stage) only if T°Inlet
≥ (SP_Water (3321) + 0.8K).
Then the power factor can go up to the 32.2% (2 stages) only if T°Inlet
≥ (SP_Water (3321) + 1.6K).
(2x0.8K)
, 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 back-up 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,

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. The 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 fans are started several times (3623) or if compressors are operating for more than 6 minutes, stop the compressors,
5. Reverse the 4 way valve,
6. 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
Climatic
TM
50 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” operation.
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 manages 3 different strategies for the fan and compressors, defined by the setting (3611):
COOL, C&QUIET, QUIET. This set point controls the fan capacity (%) and the compressors in case of condensing pressure too high.
If (3611
) = “COOL“, there isn’t any control of the capacity limit of the fan. The capacity range is [0;100]%.
If (3611
) = “C&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.

COMMUNICATION
MASTER/SLAVE
Function
Link several units in order to allow a “Master/Slave” relationship between each unit.
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
Master unit,
Units 2 to 4
Slave units.
Master/Slave Modes
Several master/slave modes are available and may be configured by using set points (3913):
Cascade mode:
The units start / stop in cascade and try to reach the water capacity demand. When all units are in standby, the cascade mode selects the first unit to start the one which has the less operating hours. When all units are in running, the cascade mode selects the first unit to stop the one which has the higher operating hours.
Back-up mode:
The unit with the highest pLan address is used as a back-up in the event of a fault in another unit.
In the event of different faults on several units, the following fault priority is applied:
1. The unit stops
2. Fault in one sensor or probe
3. Fault in one or more compressors
4. Fault in a back-up heater
5. Temperature Limit fault
6. Filter fault

“Back-up mode”, except the "back-up" unit changes every Tuesday at 09.00 if none of the other units is faulty.
Master/Slave outlet temperature, outside temperature.
Function may be configured using set points (3914), (3915).
The outlet and outside temperatures used for the unit control can be determined from the following calculations:
[Not Used
[M/S Temp]
[M/S Aver.]
Each machine regulates with its own sensors,
Slave units regulate with the values of the Master unit probes or sensors,
All the units regulate with the average of the values of the probes or sensors on the bus.
To calculate the averages, the number of units connected must be entered in set point (3912).
In all modes, each unit is independent for fault management.

COMMUNICATION
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) = 0: CLIMALINK system,
(3922) = 1: ADALINK system,
(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)
Address of the unit on the bus,
(3922)
Choice of type of protocol,
(3923)
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:
Other:
03H/16H/0AH/0BH,
