2 - GENERAL DESCRIPTION

2.1 - GENERALITIES

PRO-DIALOG is a system for controlling units which use screw compressors:

w Dual circuits w Air cooled and water cooled chillers w Non reversible heat machines

PRO-DIALOG controls compressors and loaders needed to maintain the desired leaving or entering water control point. It automatically sets the position of the electronic expansion valve to maintain a correct refrigerant flow in the cooler. For air cooled units it controls the operation of the fans to maintain the correct condensing pressure in each circuit.

Safety circuits in the unit are constantly monitored by PRO-DIALOG to ensure its safe operation. PRO-DIALOG

also gives access to a Quick Test program covering all inputs and outputs excepted compressors outputs. The control features of the 30GX&HX Pro-Dialog Plus are divided into standard features and options

(additional board needed):

FUNCTIONS

** : require a CCN/Clock board All Pro-Dialog controls can work either autonomously or they can be interfaced with the Carrier Comfort Network (CCN). In the later case a communication data cable is used to connect the unit to the CCN communication bus. When Pro-Dialog system operates autonomously it retains all of its own control capabilities but does not offer the functionality of the CCN network.

3.2 - Pressure sensors

They are used to measure in each circuit :

w Discharge gas pressure w Suction pressure w Economizer pressure

and in each compressor :

w Oil pressure w Economizer pressure on first compressor and also in the second compressor if unit is not equipped

with economizer

They are electronic sensors which linearise the output signal and deliver a 0 to 5 Vdc to either the basic board or to an analog board. Three types of sensors are used.

3.2.1 - High pressure side sensors

They are used to measure discharge pressure and oil pressures when large band oil pressure transducer is not selected. Carrier part: OP12DA039

High pressure side transducer curve

3.2.2 - Large band pressure sensors

They are used to measure oil pressures for unit operating with low ambient (when large band oil pressure transducer is selected).

3.2.3 - Suction Pressure and Economizer Pressure sensors

These are in the low pressure side. Suction pressure transducer takes the place of the low pressure switches, low pressure gauges and the low pressure safety switch (where these are usually fitted). Economizer pressure is used to measure the intermediary pressure between low and high pressure. The oil pressure is subtracted from

this pressure to determine the oil differential pressure for oil pressure safety purpose.

Carrier part: OP12DA040

Low pressure transducer curve

3.3 - THERMISTORS

All thermistor, excepted the reset sensor, have similar characteristics (see next page). They have Carrier Part No. HH 79 NZ 047

3.3.1 - Discharge gas temperature

This is installed on the discharge pipe of each compressor. It is used to control the discharge superheat. The discharge gas temperature (lowest discharge compressor temperature or average discharge temperature of both compressors) is subtracted to the saturated condensing temperature to determine the discharge superheat.

4.2.1 - General

Four types of configuration are available:

wThe factory configuration. It describes the "hardware" structure of the unit (e.g. the number of compressors,

valve...). This configuration is accessible through the Main Interface Factory menu Menus or the Network Service Tool and can be done by Carrier factory or service only.

wThe Service configuration. It allows to modify operating parameters. This configuration is accessible

through the Main Interface Service Menus or the Network Service Tool and can be done by Carrier factory or service only.

wThe User configuration. It allows to modify a limited number of simple parameters (i.e. loading sequence,

start-up delay, cooler pumps control, reset select...). This configuration can be done through the Main Interface or through the Network Service Tool. This configuration can be modified by the customer.

wThe network configuration. It allows to modify parameters used by network functions (i.e. Alarm POC,

Broadcast ...). This is accessible through the Building Supervisor or the Network Service Tool.

13. Yes = Use Pro_dialog 4 auxiliary boards instead of old 4xAO-2xAO board and 4xDO board No = Use old 4xAO-2xAO board & 4x DO board (shall be set to no for version 1 retrofit)

3. W hen this item is selected, both compressor use the common economizer transducer in the economizer. Otherwise, each compressor uses it own economizer transducer, located in the refrigerant injection pipe line, near the motor cooling valve. Economizer pressure represents the intermediary pressure between high pressure and low pressure. It is used to determine the oil differential pressure (oil pressure economizer pressure).

4. The use of large band oil pressure transducer is required for low ambient application and is only applied on oil pressure transducers since high pressure range transducer can not read pressure lower than 2.4 bars, Calibration is automatically determined each time the control is in OFF mode and both suction and discharge pressures are equalized. Differences between oil pressures and suction pressure are then stored as offset (if less than 0.4 bar).

5. MTA configuration is required for capacity calculation, motor current measurement and protection. This value shall match the one read from MTA header configuration on screw compressor board, if not an alarm will be generated.

6. If only reclaim sensor is selected and reclaim option is not, an 4xAI-2xAO board is required, and reclaim temperature sensor are used for information only.

7. Reclaim option requires an Aquasnap Basic board for reclaim entering and leaving temperatures, solenoids, an analogue output to control the reclaim condenser water valve, 2 transducers for reclaim pumpdown injection pressure.

8. This items indicates the number of pass the cooler fluid goes through the cooler. For example, if cooler enters from circuit A and goes out by circuit A and only 1 time, then a number of 2 shall be entered. This item is used for exv control when caculating cooler pinch.

9. This items indicates if cooler leaving temperature sensor is in the circuit A or not. If cooler leaving pipe line is on side A, then Yes shall be entered, otherwise, no shall be required. This item is used for exv control when caculating cooler pinch.

10. Cooler heater option requires an Aquasnap Basic board for refrigerant isolation solenoids and heater output.

11. Factory password is required when accessing the main interface factory menu. Factory password can be used to access to service and user configuration sub menus.

12. 1500 = For Muller valve, Unipolar, 1500 steps, 33 steps/s (1500 steps shall be kept !!!) 15000 = For Muller valve phase 3, Bipolar, 15300 steps, 300 steps/s (for future use,)

2. Used to set fan cycling. Decreasing this value will increase fan cycling. This timer can be reduced since the unit is fitted with an important number of fan stages, as to increase the condensing control accuracy. But in certain cases, notably on units with few fan stages, at too small value can causes superheat hunting problems.

3. Used to set fan cycling. Default value is 5 ^C, 11.1^C or higher value are recommanded if unit has varifan. This value can be increased on units with few fan stages to avoid superheat hunting problems.

4. This configuration applies to varifan or water valve upon unit type. It is used to adjust the head pressure control PID loop. Normally this decision has not to be modified for Varifan. For water valve it can be adjusted upon water valve type and installation.

5. Upon the operating capacity, the discharge superheat is adjusted as follows :

discharge superheat control point = setpoint + 3.8^C (7^F) if no loader ON. discharge superheat control point =setpoint + 1.7^C (3^F) if one loader ON. discharge superheat control point =setpoint if both loaders ON.

6. This setpoint is used by the EXV control in order to maintain an optimal cooIer exchange delta temperature between leaving temperature and saturated suction temperature. This is done in compensation with discharge superheat temperature which has higher priority.

7. This decision allows to set the high pressure override threshold:

wIf the saturated condensing temperature is greater than [the maximum condensing temperature override

threshold minus the maximum condensing temperature override differential] but less than the [maximum condensing temperature threshold] then the capacity increase shall be inhibited.

wIf the saturated condensing temperature is greater than the [maximum condensing temperature override

threshold] then one stage capacity of the corresponding circuit shall be removed (doesn't apply to the last stage).

8. This decision allows to set the high current override threshold:

wIf the compressor current is greater than [the maximum current setpoint threshold minus the maximum

current override differential] but less than the [the maximum current setpoint threshold] then the capacity increase shall be inhibited.

wIf the compressor current is greater than [the maximum current setpoint threshold] then a loader of the

circuit or the compressor will be stopped.

wcurr_max and curr_dif are in percent of MTA (Must Trip Amps). curr_max shall not exceed 85% as the

screw compressor board shall stop the compressor for alarm when current reaches 85% of MTA.

9. The Global chillers use compressors which have better performance at full load than at part load. Therefore the loading sequence strategy will be different from the one for flotronic II or pro-dialog 30 G & H control. When compressor is on, it will try to avoid the compressor operate at low capacity (no loader ON). If this item is enable, the control will use any stage of capacity in order to keep the exchanger leaving temperature as closed at possible to the control point what ever the compressor performance. When the circuit is in capacity override (compressor status LEDs in the synopsis are blinking), the control will force the close control capacity variable to enable until the circuit is no more in override.

10. This decision allows to set the setpoint which is used for auto Z Multiplier calculation. The Z Multiplier calculation tries to maintain, for each compressor, a maximum number of starts per hour equal to [zm_spt]. Thus, decreasing the setpoint shall increase the reactivity of the auto Z Multiplier to compressors cycling.

11. The Z Multiplier parameter allows to adjust the on/off time delay between compressors staging. It doesn't affect loaders staging. Increasing this value shall increase the on/off time delay but shall reduce the accuracy on the leaving temperature control.

wTthe current Z Multiplier is the result of calculation based on the number of starts of compressors.

However, the maximum Z multiplier calculation will be limited to the value entered in this decision.

12. This item allows the entering fluid control. Default is leaving fluid control. Entering fluid control can be used for small charge.

Decisions description:

1. This decision allows the unit to operate as master or a slave in a two chillers master/slave. The master

chiller monitors all external commands as start/stop, demand limiting, setpoint select or reset via CCN bus.

Control of the slave chiller is done through commands (start/stop, demand limit, setpoint, heat cool)

emitted by the master chiller. The slave will not be allowed to operate as a slave if its CHIL_S_S,

CTRL_PNT or DEM_LIM, HC_SEL variables has a force priority higher than a control force.

2. This timer is started when all conditions to start the lag chiller are satisfied. Lag chiller shall not be started

until this timer is elapsed. To be set in the master unit table only.

3. This decision allows to activate two chillers lead/lag balance function. It is used for master/slave chiller

running time equalization. When this function is active, once per day or each time the master chiller is

switched from the off to the on state the control determines the lead chiller based on both chillers run hours

delta. When the run hours delta is greater than the configured lead/lag balance delta then a changeover

will occur and the unit with the smallest operating hours value will become the lead. This function cannot

operate if the master chiller demand limit is less than 100%. In that case, the master chiller will always be

the lead. To be set in the master unit table only.

4. This function allows to set the lead/lag balance delta used for master/slave chiller running time

equalization. Lead/lag changeover occurs when the lead/lag operating time delta overlaps the configured

balance value and provided that master unit is not under demand limit control.

5. This decision allows to set the lead chiller pull down duration before the lag chiller starts.

4.3 - Cooler Interlock contact

A contact to check the status of a safety loop is provided (cooler flow switch and customer interlock are wired internally in series). Its function is to prevent the unit from starting if the contact is open while the delay at startup has expired. The contact must also stay closed as long as the unit is not stopped through Local, Remote or CCN control.

If the cooler pump is controlled by the pro-dialog and if the cooler contact is closed after 2 minutes the cooler pump is turned OFF provided that the contact is failed CLOSED, the alarm 75 shall be active and the unit can't no more start until manual reset.

4.4 - Cooler heater control

This function is applied only for air cooled units and is related to the cooler pump function when the unit state is OFF or when unit operates as a lag chiller in master/slave operation and in standby mode. This is provided on outdoor unit as a safeguard against the cooler freezing. The cooler heater is associated with refrigerant isolation solenoids, one output per circuit whose goal is to prevent the refrigerant from migrating into the condenser when chiller is stopped.

The following logic shall be used:

wIf the outdoor air temperature is below the cooler heater trip point and if either the saturated suction temperature

of circuit A or saturated suction temperature of circuit B are lower than the cooler heater trip point plus 3.3 ^C, the cooler heater shall be activated.

wNormally the isolation valves shall prevent refrigerant in the cooler from migrating into the condenser. For this

case, cooler heater can ensure cooler protection efficiently without the need of using cooler pump.

wIf it is not the case (SST remain low), the pump shall be turned on every 7 minutes to check freezing conditions

and additional heat to the cooler : cooler fluid temp (< 3° - [SSTa + SSTb]/2). Pump shall be turned of if cooler fluid temp > (8°C - [SSTa + SSTb]/2).

wIf both saturated suction temperatures of circuit A and circuit B are greater than the cooler heater trip point plus

5.5 ^C, the cooler heater shall be turned off. The pump shall be allowed to stop.

heater trip point = freeze + heat_spt (heat_sp from SERVICE2 table)

freeze = 1.1 for water, coldest setpoint - 4.4^C for brine

4.5 - Oil heater control

Each circuit has its own oil separator fitted with an oil heater. Both circuit oil heater are controlled independently . Since there is no oil temperature sensor, the oil heater will be controlled based on the saturated condensing temperature as follows :

wOil heater ON when outside temperature is below 17°C. wOil heater OFF when outside temperature is above 25°C wOil heater OFF when circuit is in operation or oil level is low (oil_sw is OPEN).

4.6 - Motor Cooling Control without plate exchanger economizer

The screw compressor motors used in the Global Chiller control are refrigerant cooled. The control strategy for motor cooling relies on vapor at light loads, and supplementary liquid refrigerant at high loads. Each compressor will have its own cooling solenoid. An additional motor cooling solenoid is required when operating in high condensing temperature. It is automatically controlled by pro-dialog even if it is not mounted in the units. The motor cooling solenoids shall be cycled to allow liquid to cool the motor. The main motor cooling solenoid control is based on the motor temperature and its setpoint (83°C) using a quasi-fuzzy logic . The additional motor cooling solenoid control is just based on the discharge gas temperature.

4.7 - Motor Cooling Control with sub cooling plate exchanger

The sub cooling plate exchanger replaces the old economizer for simple maintenance and cost reduction. Thus the screw compressor motors are cooled by refrigerant from the plate exchanger, located between condenser and exv (see scheme below). The refrigerant flow through this exchanger for motor cooling purpose is controlled by a thermal expansion valve. The opening of this valve is done by heating its internal resistor via 24 vac ouput signal from the screw compressor board, channel 13. For circuit which has 2 compressors, an additional solenoid (see scheme below, x=a for circuit A, x=b for circuit B) shall be controlled to balance motor temperatures. These solenoid output are located at channel 14 of the screw compressor board.

4.7.1 Motor Cooling Control with TQ feedback Signal Control

(refer to factory configuration and wiring for retrofit, pages, 21, 23 and 24)

Tq valve opening position depends on the heat (resistor is the image) on the TQ valve and also the equalisation pressure located at plate exchanger (in our application, quite the same than economiser pressure).

With the same economiser pressure, the higher heating signal is commanded (CPA1_PUL, or CPB1_PUL), the lower is the resistor and the more the valve is opened.

With sam e heating signal value, if the economiser pressure increases, the valve will tend to close. And vice versa

Based on this relation, if the feedback s ignal is enabled, the control will check all the time the relation TQ position = F (economis er pressure/T Q resistor) and shall m ake a k ind of override (absolutely required at the start-up, resistor is very high) When a value of 200 is sent on CPA1_PUL or CPB1_PUL (hardware SIO variable) some time, that means resistor value is a little above the minimum position, preheat is sent. This value is sent also when loading capacity.

When the econom iser pressure is steady, and TQ resistor is near to the pre-opening position, regular control (PID) is used.

TQ resistor sens or is connected to the EXV board. T he value read is in K Ohm s MTQ_RESA (for circuit A), MTQ_RESB (for circuit B). During regular operation, value read shall be from 0.7 k Ohm to 4 k Ohms.

4.8 - CAPACITY CONTROL

This function adjusts the number of active compressors and loaders to keep the leaving water temperature at the setpoint. The precision with which this is achieved depends upon the capacity of the water loop, the water flow rate, the load and the number of capacity control steps available. The control continuously takes account of the temperature error with respect to the control point, the rate of change of the leaving fluid temperature and the delta of temperatures between the entering and leaving fluid in order to determine the optimum time to add or subtract steps of capacity.

Note: a too important number of starts of a particular compressor will automatically cause a limitation of the compressors starts. This will affect the precision of the water loop temperature control.

4.8.1 - Logic description

4.8.1.1 - Basic logic

To operate the capacity control task uses the following inputs:

w EWT Entering water temperature w LWT Leaving water temperature w CTRL_PNT Control point w Cooling z_multiplier Z Multiplier (range: 1.0 to 6.0) w Heating z_multiplier Z Multiplier (range: 1.0 to 6.0)

The control calculates the SMZ: load/unload factor. It is compared to the z_multiplier to determine when to add or remove stage:

w If (sum/z) > +z_multiplier -> stage = +1 (add a compressor) w

If (sum/z) > +0.6 and if a loader is available (loader is OFF) -> stage = +1 (add a loader)

w If (sum/z) < - z_multiplier -> stage = -1 (remove one compressor) w If sum/z) < -0.6 and loader is avaialble (loader is ON) -> stage = -1 (turn off one loader)

Note

: z_multiplier doesn't apply to loaders.

4.8.1.2 - Z Multiplier calculation

The z_multiplier factor allows to indirectly increase the compressor on/off time delay. In consequence, it can be adjusted (increased) to avoid compressors short cycling. This function requires the following Service configuration:

vAuto Z Multiplier sepoint (zm_spt). Default to 6. vCooling and heating Z Multiplier max value (hc_zm). default to 6.0.

This function adapts the z_multiplier to the unit compressor cycles number (the cycle number shall be based on the compressor which has been the most started during an hour). The significant period for compressors cycling shall be of one hour.

If the cycle counter exceeds the setpoint (zm_spt), then the z_multiplier value shall be increased based on the cycle number (PID loop). The function shall not take care of the loaders cycling.

The calculated value of the z_multiplier shall not exceed the configured hc_zm. If the unit returns to normal operating condition with a cycles counter going down then the calculated z_multiplier shall progressively return to its normal value (zm = 1.0). The rate at which the calculated z_multiplier returns to normal shall be lower than the rate at which it is increased.

The setpoint value shall allow to adapt the auto z multiplier calculation to the installation. The setpoint ranges from 4 to 6.

During normal operation, each modification of the unit capacity is followed by a dead time when no capacity modification is possible. The duration of this dead time is 90 seconds.

Note : When overrides 2,3 , 5, 6, 16, 17, 18, 19, 20, 21 are active, the variable close control (cls_ctrl) shall be enabled whatever the configuration to allow unloading the last loader in the circuit.

Chiller Current Override (override #35) This function allows customer to limit the total current (it does not include current of fans, valves, heaters, oil pumps

...) of all the compressors during operation. The chiller current limit can be modified through USER configuration (USER table or User configuration by main interface). This function is similar to demand limit function.

wIf the chiller current is greater than the chiller current limit , then a stage of capacity will be removed. wIf chiller current plus the added current of selected compressor is greater than the chiller current limit, the

increase of capacity will not be allowed. If the compressors is OFF, its added current is 80% of its MTA. If the selected compressor is on but deos not reach 100% capacity, an added stage on the same compressor will add 40% of its current.

4.9 - COMPRESSORS & LOADERS LOADING SEQUENCE

4.9.1 - General Description

The Global chillers uses compressors which have better performance at full load than at part load. Therefore, the loading sequence strategy will be different than for the flotronic II or for the Pro-dialog 30 G & H. The following list applies only to capacity control. For High Ambient Unloading, it can be overridden.

1. A compressor will not be started until all other running compressors are 100% loaded.

2. On units with 3 compressors, both circuits cannot have their loaders off at the same time once 3 or more of the compressors in the unit are on. Where possible, the circuit which is starting a compressor will be the one which is to be unloaded.

3. Any time a lag compressor in a circuit is starting, the loaders in the circuit shall be turned off (unloading all compressors in the circuit). This shall be done 15 seconds prior to starting the new compressor. 15 seconds after the new compressor has started, the loaders shall be set to their desired state. When a lead compressor is starting, all loaders shall be turned off when the compressor relay is turned on (+/- 2 seconds), and shall be set to their desired state 15 seconds after the compressor has been started.

4. There shall be a configuration decision for "close control", which (when selected) will cause the control to utilize all of the loading devices to achieve better leaving water temperature control.

5. Whenever any compressor in a circuit is going to be stopped normally, the circuit shall be fully unloaded for 15 seconds prior to shutting down the compressor. This shall not apply when the reason for a shutdown is due to an alarm condition.

7. For any shutdown, all compressors and loaders will be shut down at the same time.

For more than 2 compressors, two types of sequencing are available and configurable by the user through either the Main Interface or through the CCN network:

w Equal circuit loading: The control shall attempt to maintain equal capacity between the circuits as the machine

loads and unloads.

w Staged circuit loading: The control shall load the lead circuit completely before the lag circuit is started. When

the load is decreasing the lag circuit shall be unloaded first.

Circuit compressors sequence select shall try to equalize the compressor starts number. That means any compressor in the circuit can become the lead compressor if it has the lowest starts number, however, this shall be balanced with the operating hours.

Loaders in the same circuit are commanded simultaneously. Thus one loader variable is displayed. When a circuit is overridden (compressor status are blinking in the synopsis) because of low suction

temperature, low or high discharge temperature or high condensing temperature (high pressure), or high current then no capacity increase shall be allowed on the affected circuit. This circuit is selected to unload capacity first when unloading capacity condition is required.

4.9.2- Compressor capacity determination

Each compressor has three stages capacity. Simulation had been done to determine the average capacity corresponding to those stages as following :

No loader ON -> 40% Only loader_1 -> 70% Both loaders ON -> = 100%

4.10 - EXV CONTROL

4.10.1 - General

The EXV is controlled to maintain minimum pinch for insuring the cooler exchange performance through the delta temperature between the cooler fluid and the saturated suction temperature. EXV opening movement will normally decrease the cooler pinch and thus increase the cooler exchange performance. But it shall not open too much provided a drop in discharge superheat , low oil pressure and refrigerant flow.

The EXV control shall deal with two goals : Smaller Cooler Pinch and Discharge Superheat Protection. Additional protection against excessive EXV opening is applied to ensure the condenser heat transfer (sub cooling).

It may happen when operating in high condensing temperature and indirectly high discharge superheat, exv would tend to open continuously to get the lower pinch due to the setpoint and unfortunately in certain conditions, this value has reached the limit, though it is higher than the setpoint. Therefore, EXV position limit shall be set when there is no more variation in cooler pinch for a variation of EXV position of 4 percent.

EXV position shall also be limited to avoid hunting problem due to low discharge superheat protection. It may occur when operating in a low condensing temperature, the discharge superheat protection can switch from enable to disable in few scans and so on.

This control uses a kind of auto adaptive method whose goal is to find out the optimal position of EXV for insuring an optimal pinch with a correct discharge superheat and sub cooling.

4.11 - Air Cooled Condensing Pressure Control

Head pressure differential value and head pressure differential timer can be adjusted in the Service menu. Decreasing these values will increase fan cycling. This differential value and timer can be reduced since the unit is fitted with an important number of fan stages, as to increase the condensing control accuracy. But in certain cases, notably on units with few fan stages, at too small value can causes superheat hunting problems. Varifan PID gains can be modified in the Service menu (not recommended). See section 4.2.3.

4.14 - High Pressure (Maximum Condensing Temperature) Override

This function shall be used to avoid circuit high pressure trip while the condensing pressure reaches a configurable override threshold (Service 1 Configuration).

wIf the saturated condensing temperature is greater than the maximum condensing temperature (mct_sp) minus

the maximum condensing temperature override differential (mct_diff) but less than the maximum condensing temperature (mct_sp) then the circuit capacity increase shall be inhibited.

wIf the saturated condensing temperature is greater than the maximum condensing temperature (mct_sp) then the

4.16 - Stopping Function

4.16.1- Stopping a compressor by capacity unloading

If the selected compressor is operating with at least one loader ON, then all the loaders in the same circuit shall be de-energized for 15 seconds before stopping the compressor.

4.16.2- Stopping the unit by manual command (OFF)

Both circuit shall decrease its capacity progressively every 15 seconds. One loader is immediately de-energized. The last loader will be de-energized in 15 seconds later. Then all compressors, oil solenoids and oil pump will be de-energized in 15 seconds after the last loader is turned OFF. Here is an example of the stopping function with time indicator for a circuit with both loaders ON before receiving a STOP command.

4.17.2- Oil pump control

The oil pump is generally used to provide pre-lubrification of the compressor. Moreover, it is controlled to insure a correct oil pressure during capacity transition or during operation with low condensing temperature that cause a drop of oil pressure to avoid tripping in alarm.

Thus the oil pump is turned ON when the Differential Oil Pressure is lower than Oil Setpoint 1 plus 13 kpa. and remained ON until Differential Oil Pressure is greater than Oil Setpoint 1 plus 35 kpa AND difference between discharge and economizer pressure is greater than Oil Setpoint 1 plus 150 kpa to avoid oil pump cycles.

4.18 - Reclaim Operation

4.18.1 - General Description This function shall control the air cooled to reclaim or the reclaim to air cooled changeover process. Reclaim changeover shall be caused either by:

wA manual reclaim select change due to a local, remote or CCN command on the unit wA heat reclaim temperature change while reclaim has been selected. This algorithm monitors the entering

reclaim sensor temperature and compares it with the reclaim setpoint to determine if the reclaim can be active or not.

If the reclaim function has been selected, the reclaim shall become active when the entering reclaim temperature comes below the reclaim setpoint minus the reclaim deadband and delay between the last air cooled to reclaim session is elapsed. It shall become inactive when the entering reclaim temperature comes over the reclaim setpoint plus the reclaim deadband.

Non-reclaim to reclaim Changeover shall follow this procedure:

wTurn on the reclaim condenser pump wVerify the condenser flow is established, if not after 1 minute delay has elapsed, reclaim operation shall be

aborted and an alarm shall be displayed.

wWait for 3 minutes after condenser pump is ON and until the saturated condensing temperature reaches (30

deg C) and superheat is greater than 8.6 ^C

w If saturated condensing temperature is greater than reclaim setpoint + 3.3^F, go to reclaim operation directly (it

is not necessary to make an pumpdown) otherwise, go through pumpdown (see below)

wStart the pumpdown sequence : reclaim discharge valve shall be closed and reclaim pumpdown injection valve

shall be open.

wClose EXV 6.67 or 3.33% upon the number of compressors on circuit every 10 seconds while pumpdown

pressure is greater than 300 kpa (44 psi), during first minute if EXV is less than 15 % opened.

wAfter a 10 minutes duration or as soon as pumpdown pressure is lower than 300 kpa (44 psi), reclaim injection

valve shall be closed, reclaim operation is effective. Open EXV 13.33% as avoid low saturated suction alarm.

wWhen reclaim operation is active, each circuit fan staging has its own saturated condensing control point

determined as follows:

sct_ctrl_x = (hr_ewt + hr_lwt)/ 2 + rsp_x_a * capacity_x + rsp_x_b (x for circuit), rsp_x_a and rsp_x_b are service parameters in table SERVICE2.

wPumpdown shall not be necessary if saturated condensing temperature is greater than reclaim setpoint + 6 ^C

Reclaim to non-reclaim Changeover shall follow this procedure:

wTurn off the condenser pump. wClose the reclaim pumpdown valve. wOpen the reclaim discharge valve if at least a compressor is ON. Otherwise, Close it.

During reclaim operation, if the pumpdown pressure is greater than 400 kpa (59 psi), the pumpdown procedure in non_reclaim to reclaim session shall be initiated. When the number of these abnormal sessions exceeds 2 times, the reclaim operation shall be aborted, the circuit shall return to air cooled mode and an alarm shall be displayed.

At power up or after reset or after the unit capacity goes down to 0%, the function shall return to air cooled mode.

4.18.2 - Reclaim To Air Cooled Changeover Initiation This shall determine whether the unit shall return to air cooled mode. This can be caused by the following:

Cause #1

: Reclaim operation active and reclaim select is no more active

Cause #2

: Reclaim mode is active and the entering reclaim temperature is above the range of the reclaim

setpoint + the reclaim dead band divided by 2 : HR_EWT >rsp + hr_deadb/2 Cause #3: Number of consecutive reclaim pumpdown sessions exceeds 2 times Cause #4

: entering reclaim temperature sensor failure

When turning ON, the remained condenser (hr_val_a) is kept to ON for at least 3 minutes to let fans staging to be stabilized. This condenser can be turned OFF if it has been ON for more than 3 minutes and if saturated condensing temperature is below the reclaim setpoint (rsp) to ensure the reclaim operation performance.

4.18.6 - Reclaim Condenser Water Valve Control if unit is not in reclaim operation, then the reclaim condenser water valve remains in minimum position. In reclaim operation :

wIf reclaim entering temperature is below 20 deg C, then reclaim condenser valve is at minimum position. wIf reclaim entering temperature is above 40 deg C, then reclaim condenser valve is at maximum position. wIf entering temperature is within the range 20 degC and 40 deg C, then reclaim condenser water valve position

will be an interpolation between minimum and maximum position.

4.18.7 - Reclaim Condenser Heater Control Reclaim condenser heater is ON when entering or leaving fluid are lower than 3.0 deg C( 37.4 degF). It is turned

4.19 - Two Units Master/Slave Control

4.19.1 - General

This function allows to perform master/slave plant control between two chillers linked by the CCN network. Master and slave chiller need to operate on the same bus. Master/slave operations shall operate in cooling or heating mode.

To operate properly, the master and the slave chillers must have an additional CHWS sensor located on the common chilled leaving piping when the water control is done on the outlet side. This CHWS sensor shall be connected on each chiller basic board. When the water system control is done on the inlet side no additional CHWS sensor is required.

Parallel chiller control with dedicated pumps is recommended. Chiller must start and stop its own water pump located on its own piping. If pumps are not dedicated for each chiller pimping, chiller isolation valves are required: each chiller must open and close its own isolation valve through the control (valve shall be connected to the pump outputs).

Water system control with no individual chiller pump control is feasible. It is not recommended when the system load is low or if the control point is close from the freeze water tripping point (because of system instability that can be caused by the freeze protection override). System flow is constant even if the master or the slave chiller is stopped. In that case, the system pump shall be controlled by the master chiller.

Series chillers with dedicated primary pumping and constant flow shall be feasible but not recommended. Pump start/stop must be controlled externally. Each series chiller must control its own isolation and bypass valves: stopped chiller must be isolated from water flow (chiller pump command shall be used for valves control. Each chiller must open and close its own chilled isolation valve).

The master chiller shall monitor all external commands as start/stop, demand limiting or setpoint select. It needs to be started in Master operating type. The slave chiller must operate in CCN mode. If the master chiller is turned off while the master/slave function is active then, the slave chiller shall be stopped.

The master/slave linkage shall not be allowed to operate if any one of the slave chiller CTRL_PNT, DEM_LIM, LAG_LIM, CTRL_PNT HC_SEL or LCW _STPT variables has a force priority higher than a control force. In that case, the master slave operations shall not be allowed or shall be disabled.

The control of the slave chiller shall be done through commands emitted by the master chiller. The slave chiller has no action in the master/slave operations: it shall only verify that CCN communication with its master is correct.

The master function shall provide the ability to select a lead chiller among the master and the slave. Selection shall be based on the delta between the master and the slave run hours and shall try to optimize the runtime hours. If this function is unused then, the lead chiller shall always the master. Lead/lag changeover between the master and the slave due to hour balance shall occur during chiller operations odd days at 12:00 a.m. or at startup.

The lead chiller shall always be started first and the lag chiller shall be maintained at zero percent capacity through master forcing the lag demand limit value (LAG_LIM) to 0%. The lag water pump shall be maintained off. When the lead chiller cannot be loaded anymore (because it is loaded at its full available capacity or at the master demand limit value) then the lag start timer is started. When the lag start timer is elapsed, if the error on the master controlled setpoint is greater than 3^F and if the pulldown time is elapsed then, the lag chiller water pump shall be turned on (if required by configuration) and the lag chiller shall be allowed to start through master forcing the lag chiller demand limit value (LAG_LIM) to its own demand limit value. To ensure that the lag chiller will be unloaded first in case of water load decrease then, the lead chiller setpoint error shall be reset of upwards 4^F provided that the lag capacity is not zero.

The lead pulldown time tells how long after starting the lead chiller (one time after the master chiller status has been manually started) before checking whether to start an additional chiller. This time delay gives the lead chiller a chance to pull down the loop temperature before starting another chiller.

If a communication failure is detected between the master and the slave then, all master/slave functions shall be disabled and chillers shall return to standalone operations until communication is reestablished.

Note: to ensure that no compressor is started before the flow rate is correctly established then, the water flow control is absolutely required on the lag chiller for master slave operations.
