The system controls cooling load within the set point plus and minus the dead band by sensing the water or brine temperature and regulating the inlet guide vane via a mechanically linked actuator motor, and regulating VFD (variable frequency drive) speed if the compressor is powered by a variable speed drive. The guide vane is a variable flow pre-whirl assembly that controls the refrigeration effect in the cooler by regulating the amount of refrigerant vapor flow into the compressor. An increase in guide vane opening increases capacity. A decrease in guide vane opening decreases capacity. The microprocessor-based control center protects the chiller by monitoring the digital and analog inputs and executing capacity overrides or safety shutdowns as necessary. The PIC 5 control system also provides access to a Control Test function covering all outputs except compressor relay outputs. rigging, and setting this equipment, and in handling all electrical components.

These electronic sensors deliver 0 to 5 VDC. The transducers can be calibrated through the controller. The pressure transducers are connected to the IOBs. See Table 6. EVAPORATOR/CONDENSER WATER PUMP — The controller can regulate an optional evaporator/condenser water pump. INLET GUIDE VANE — The inlet guide vane adjusts the refrigerant vapor flow into the compressor to adapt to change in the operating conditions of the machine. To adjust the refrigerant flow, the guide vane opens or closes to vary the crosssection of the refrigerant path. The high degree of accuracy with which the guide vane is positioned ensures that the flow of refrigerant is precisely controlled. ECONOMIZER DAMPER VALVE — The economizer damper control opens or closes the economizer damper valve to maintain a minimum refrigerant pressure difference between the evaporator and economizer. HGBP VALVE — The hot gas bypass function artificially loads the chiller and keeps it running under low load conditions or helps to prevent surge conditions. Since this function can also reduce the operating efficiency of the machine, this is a user-selectable and configurable option. VFD — The VFD modifies motor frequency to allow compressor start-up and capacity control. The VFD controls continually monitor parameters in order to ensure compressor protection. Should a problem occur, the controller triggers an alarm and the compressor is stopped if necessary.

There are four selectable control modes: LOCAL, LOCAL SCHEDULE, REMOTE, or NETWORK. See Unit Start/Stop Screen on page 18. Specific control sources are valid to start or stop the chiller for each control mode. LOCAL — When the control mode is LOCAL, the chiller can be started by the “Local ON” button on the PIC 5 interface screen, and can be shut down by the Confirm Stop button on the screen or by the EMSTOP software point. LOCAL SCHEDULE — When the control mode is LOCAL SCHEDULE, the chiller will be started automatically if the configurable local schedule is Occupied. The chiller can be shut down by the unoccupied schedule, the Stop button on the PIC 5 interface screen, or by the EMSTOP software point. REMOTE — When the control mode is REMOTE, the chiller will be started by the remote discrete input (REM_CON) located on the I/O board. The chiller can be shut down by the remote discrete input, the Stop button on the PIC 5 interface screen, or by the EMSTOP software point. NETWORK — When the control mode is NETWORK, the chiller can be started and stopped by the CHIL_S_S and CHIL_OCC software points, which are written by other equipment through network commands and network schedule. The chiller can also be shut down by the EMSTOP software point. NOTE: There is a STOP OVERRIDE point in the GENUNIT table. If this point is enabled the chiller cannot be started and will shut down the chiller if it is running. Chiller Start-Up Sequence PRE-START CHECK — Once start-up begins, the controller performs a series of pre-start tests to verify that all pre-start alerts and safeties are within limits. Progress is shown on the Startup Sequence screen (see Fig. 34). Table 11 lists pre-start alert and alarm conditions. Startup Sequence Fig. 34 — Start-Up Sequence Screen 21 The control then waits until the oil pressure (OIL PRESS VERIFY TIME, operator-configured, default 40 seconds) reaches a maximum of 18 psi (124 kPa). After oil pressure is verified, the control waits 40 seconds for oil prelube, and the compressor start relay energizes to start the compressor.

ALERT 100 Alert 101 Alert 102 Alert 103 Alert 230 Alarm 231 Alarm 232 Alarm 233 Alarm 234 Alarm 235 Alarm 236 Alarm Chiller Shutdown Sequence — Chiller shutdown begins if any of the following occurs: • Local OFF button is pressed • A recycle condition is present (see the previous section) • The time schedule has gone into unoccupied mode • The chiller protective limit has been reached and chiller is in alarm • The start/stop status (CHIL_S_S) is overridden to stop from the network If the chiller is normally shut down from running, a softstop shutdown will be performed. The soft-stop feature closes the guide vanes of the compressor automatically if a non-alarm stop signal occurs before the compressor motor is deenergized. Any time the compressor is directed to STOP (except in the cases of a fault shutdown), the guide vanes are directed to close and VFD will be commanded to minimum speed for a variable speed compressor. The compressor shuts off when any of the following is true: • AVERAGE LINE CURRENT (%) drops below the SOFT STOP AMPS THRESHOLD • ACTUAL GUIDE VANE POSITION drops below 4% • Four minutes have elapsed since the stop was initialized When any of these conditions is true, the shutdown sequence stops the compressor by deactivating the compressor start relay. The guide vanes are then commanded to the fully closed position. The oil pump relay will be turned off after 60 seconds post-lube. Finally, the chilled water/brine pump and condenser water pump are shut down. *Evap trip point = 33 F (0.6 C) (water) or EVAP REFRIG TRIPPOINT (brine). The compressor RUN STATUS parameter on the default screen line now reads PRESTART. If a test is not successful, the start-up is delayed or aborted. If the tests are successful, the chilled water pump relay energizes, and the main screen line now reads STARTUP. START-UP — One second after the successful pre-start check, the chilled water and condenser water pump relays are energized. Five seconds later, the control monitors the chilled water and condenser water flow devices and waits until the WATER FLOW VERIFY TIME (service-configured, default 5 minutes) expires to confirm water flow. After water flow is verified, the water temperature is compared to CONTROL POINT + 1/2 CHILLED WATER DEADBAND. If the temperature is less than or equal to this value, the control turns off the condenser pump relay and goes into RECYCLE mode. If the RECYCLE condition does not exist, the start-up sequence continues and checks the guide vane position. For a single-stage compressor (Comp [Single = 0, Dual = 1] = 0 in FACTORY configuration), if the guide vanes are more than 4% open, the start-up waits until the controller closes the vanes. For a dual-stage compressor (Comp [Single = 0, Dual = 1] = 1 in FACTORY configuration), the guide vanes are opened to the initial position specified with GV1 Closure at Startup in the Option Configuration menu. If an HGBP or economizer damper valve is equipped and enabled, the control checks that the position of these valves is fully closed. If the vanes and valves position are verified and the oil pump pressure is less than 4 psi (27.6 kPa), the oil pump relay is energized. Oil Lubrication Control — As part of the pre-start checks executed by the controls, the oil sump temp is compared to the evaporator saturated refrigerant temperature. If the oil temperature is less than 140 F (60 C) and less than evaporator saturated refrigerant temperature plus 50° F (27.8° C), the start-up will be delayed until either of these conditions is no longer true. Once this temperature is confirmed, the start-up continues. The oil heater relay is energized whenever the chiller compressor is off and the oil sump temperature is less than 140 F (60 C) or the oil sump temperature is less than the evaporator saturated refrigerant temperature plus 53° F (29.4° C). The oil heater is turned off when either of the following conditions is true: • Oil sump temperature is more than 152 F (66.7 C) • Oil sump temperature is more than 144° F (62.2 C) and more than the evaporator saturated refrigerant temperature plus 55° F (30.6° C). The oil heater is always off when the compressor is running. The oil pump is also energized for 30 seconds after each 30 minutes of the oil heat relay being energized in order to stir the oil for more evenly distributed heating. Control Points SET POINT — The set point can be configured at the Setpoint menu (“USER” access level). The set point is determined by the heat/cool mode, EWT 22 POSITION if it has not reached the travel limit; if the travel limit has been reached, the control increases VFD TARGET SPEED. If decreased capacity is needed, the control first tries to decrease VFD TARGET SPEED if it has not reached the minimum VFD speed; if the minimum VFD speed has been reached, the control decreases IGV TARGET POSITION instead. See Fig. 35. From the compressor relay closed point to the end of ramp loading, the VFD TARGET SPEED is the configured VFD start-up speed. When the chiller is running normally, the capacity control determines whether and how much to change VFD TARGET SPEED. When the chiller is in the shut-down process, VFD TARGET SPEED will be the minimum VFD speed. NOTE: If the VFD option is set to NO VFD, or the compressor relay is not closed, VFD TARGET SPEED will be 0. The guide vane position is determined by the Capacity Control function under normal conditions and other functions in abnormal conditions, which include capacity inhibit request or capacity decrease request. The guide vane actuator is driven by comparing the guide vane target position and the actual position. The guide vane actual position can be viewed on the default screen, and ranges from zero to the guide vane travel limit configured from the Service Configuration menu. When the chiller is shutting down or off, the guide vane is always driven to zero. RAMP LOADING — The ramp loading control slows the rate at which the compressor loads up. This control can prevent the compressor from loading up during the short period of time when the chiller is started and the chilled water loop has to be brought down to CONTROL POINT (Setpoint Table). Ramp loading helps reduce electrical demand charges by slowly bringing the chilled water to CONTROL POINT. The total power draw during this period remains almost unchanged. Two methods of ramp loading are available: temperature ramp loading and motor load ramp loading. Temperature Ramp Loading — Temperature ramp loading limits the rate at which the controlled water temperature decreases for cooling and increases for heating during ramping by reducing on cooling mode or increasing in heating mode the PULLDOWN SET POINT (Maintenance Menu Capacity) at the configured rate, until the pulldown set point is less than the cooling mode control point or greater than the heating mode control point. The PULLDOWN RAMP TYPE (Configuration Menu General Configuration) is configured to 0 for temperature ramp loading. Motor Load Ramp Loading — Motor load ramp loading limits the rate at which either the line current percentage or motor kilowatt percentage increases by incrementing the ramp demand limit at the configured rate. The PULLDOWN RAMP TYPE (Configuration Menu General Configuration) is configured to 1 for motor load ramp loading. If DEMAND LIMIT SOURCE (Configuration Menu General Configuration) is set to AMPS, then PERCENT LINE CURRENT is used for motor load ramp loading. If DEMAND LIMIT SOURCE is set to kW, then MOTOR PERCENT KILOWATTS is used for motor load ramp loading. The motor load ramp loading algorithm shall be deactivated when the Ramp Demand Limit is greater than or equal to the ACTIVE DEMAND LIMIT (General Parameters). It is also deactivated when Ramp Demand Limit is greater than or equal to 60%. There will be a one-minute delay for the compressor to be uploaded to target load (ramping load target 60%) after ramping load demand limit is set to 60%. Table 12 — Set Point Determination EWT CONTROL OPTION Disabled Enabled HEAT/COOL MODE COOLING HEATING Cooling LCW Set Point Cooling ECW Set Point Heating LCDW Set Point Heating ECDW Set Point NOTES: 1. The ice build option is disabled when heat/cool mode is set to Heating. 2. When the ice build option is enabled and ice build is active, the control point is the Ice Build Set Point and the controlled water temperature is the leaving chilled water temperature. CONTROL POINT TEMPERATURE — Capacity control is based on achieving and maintaining a control point temperature, which is the sum of a valid set point (from the SETPOINT screen) and a temperature reset value. In Cooling mode, the control point temperature is equal to the set point plus temperature reset. In Heating mode, the control point temperature is equal to the set point minus temperature reset. The control point can be viewed directly on the main screen or the General Parameters menu. TEMPERATURE RESET — Three types of chilled water or brine reset are available and can be viewed or modified on the Reset Configuration screen. The default screen indicates when the chilled water reset is active. The control point Reset on the General Parameters screen indicates the amount of reset. To activate a reset type, access the Reset Configuration (RESETCFG) screen and input all configuration information for that reset type. Reset Type 1: 4 to 20 mA Temperature Reset — Reset Type 1 is an automatic reset utilizing a 4 to 20 mA analog input signal provided from any external sensor, controller, or other device which is appropriately configured. For this type, Degrees Reset At 20 mA is configured in the RESETCFG table. Reset Type 2: Remote Temperature Reset — Reset Type 2 is an automatic water temperature reset based on a remote temperature sensor input signal. This function can be accessed by setting the following configurations: 1. Configure the remote temperature at which no reset occurs (Remote temp NO RESET). 2. Configure the remote temperature at which full reset occurs (Remote temp FULL RESET). 3. Enter the amount of reset (Deg Reset Water DT Full). Reset Type 3: Controlled Water Temp Delta Reset — Reset Type 3 is an automatic controlled water temperature reset based on heat exchanger temperature difference. This function can be accessed by setting the following configurations: 1. Configure the controlled water temperature delta T at which no reset occurs (Controlled Water DELTA T NO RESET). 2. Configure the controlled water temperature delta T at which full reset occurs (Controlled Water DELTA T FULL RESET). 3. Enter the amount of reset (Deg Reset Water DT Full). CAPACITY CONTROL — Capacity control provides chilled or condenser water temperature control by modulating the position of the inlet guide vane 1, and VFD speed for variable speed compressors. If VFD OPTION is set to VFD and increased capacity is needed, the control will first try to increase IGV TARGET 23 VFD % SPEED MAX. START VFD AT START-UP SPEED, MODULATE GUIDE VANES STARTUP: VFD TO START-UP SPEED, GUIDE VANES CLOSED MIN. GUIDE VANES AT MAX. MODULATE VFD VFD GUIDE VANES a19-2129 0 TRAVEL LIMIT 100 GUIDE VANES % POSITION Fig. 35 — Guide Vane Position and VFD Speed CURRENT / 10]), an incidence of surge has occurred, and the surge protection signal will be sent. When an incidence of surge determined in this manner has occurred, the SURGE COUNTS will be incremented by one. On receiving the surge protection signal, Capacity Control will make corrections on IGV1 TARGET POSITION, VFD TARGET SPEED, and HGBP actuator. When correction is in effect, Surge Protection Count will be added every 10 seconds. If IGV, VFD and HGBP cannot be corrected, chiller will send a shutdown alarm when the surge count is greater than 4. HOT GAS BYPASS (HGBP) CONTROL — The hot gas bypass function is used to artificially load the chiller and keep it running under low load conditions or to prevent surge conditions. Since this also reduces the performance of the machine, HGBP Control is a user-selectable option. Hot gas bypass operation has three different modes when installed (hgbp_opt = 1) and enabled (hgbp_sel > 0): • Hot gas bypass for surge correction — Each compressor has unique lift characteristics that can be plotted to determine performance. The controller will determine operating conditions that could result in compressor surge and activate the hot gas bypass valve to prevent surge until the chiller operating parameters are in a safe area on the curve where the valve may be closed again. • Hot gas bypass for low load operation — In this condition, the hot gas bypass valve will be opened to prevent a recycle shutdown from occurring. The hot gas bypass valve will remain open until this minimal loading condition has passed and there is no surge condition present. • Combination surge correction and low load operation — When this option is selected, both HGBP for surge prevention and HGBP for low load operation will be performed. Surge prevention will take higher priority if both conditions are satisfied. SURGE CORRECTION CONTROL — There are two stages for surge correction: envelope control (surge prevention) and surge protection. Envelope Control — A surge condition occurs when the lift becomes so high that the gas flow across the impeller reverses. This condition can eventually cause compressor damage. The surge prevention algorithm notifies the operator that chiller operating conditions are marginal and to take action, such as lowering entering condenser water temperature, to help prevent compressor damage. If a high sound condition occurs at low guide vane position, the HGBP valve is used to decrease the sound level. The envelope control algorithm is an operator-configurable feature that can determine if lift conditions are too high for the compressor and then take corrective action. High efficiency mode or low noise mode can be selected. Lift is defined as the difference between the saturated temperature at the impeller eye and at the impeller discharge. The maximum lift a particular impeller wheel can perform varies with the gas flow across the impeller and the size of the wheel. If Actual Lift is higher than reference lift, a capacity inhibit signal will be sent. If Actual Lift is higher than reference lift plus Surge Line High Offset, a capacity decrease signal will be sent. If Actual Lift is lower than reference lift minus Surge Deadband, these 2 signals will be canceled. Capacity Control will respond to these 2 signals and make correction on IGV1 TARGET POSITION, VFD TARGET SPEED, and HGBP actuator. Surge Protection — The Surge Protection algorithm will run after SURGE DELAY TIME has elapsed when compressor has been commanded to turn on. It compares the present PERCENT LINE CURRENT value with the previous value once every second. If the difference exceeds the maximum AMPS change value (SURGE DELTA % AMPS + [PERCENT LINE 24 value 100%). ACTIVE DEMAND LIMIT may also be forced to be different from BASE DEMAND LIMIT by manually overriding (forcing) the value via a CCN network device. If the DEMAND LIMIT SOURCE exceeds the ACTIVE DEMAND LIMIT by 5% or less, capacity will be inhibited. If the DEMAND LIMIT SOURCE exceeds the ACTIVE DEMAND LIMIT by more than 5%, capacity will be decreased. Alternatively, the limit may be applied by by AUTO DEMAND LIMIT INPUT, an optional 4 to 20 mA input. This demand limit control option (4-20 mA DEMAND LIMIT TYPE) is externally controlled by a 4 to 20 mA signal. The option is set up on the Configuration Menu GENERAL CONFIGURATION screen. When enabled, 4 mA will set ACTIVE DEMAND LIMIT to 100% of the DEMAND LIMIT SOURCE (regardless of the value of BASE DEMAND LIMIT), and 20 mA will set ACTIVE DEMAND LIMIT to the value configured for DEMAND LIMIT AT 20 mA in the Configuration Menu SERVICE PARAMETERS screen. OVERRIDE CONTROL — Capacity overrides can prevent some safety shutdowns caused by exceeding the motor amperage limit, evaporator refrigerant low temperature safety limit, motor high temperature safety limit, and condenser high pressure limit. In these cases there are two stages of capacity control: 1. When the value of interest crosses the first stage set point into the override region, the capacity is prevented from increasing further, and the status line on the PIC 5 controller indicates the reason for the override. Normal capacity control operation is restored when the value crosses back over the first stage set point, leaving the override region. 2. When the value of interest is in the override region and further crosses the second stage set point, the capacity is decreased until the value meets the override termination condition. The PIC 5 controls resume normal capacity control operation after the override termination condition has been satisfied. (In the case of high discharge superheat, there is an intermediate stage.) Table 14 summarizes these override parameters. ECONOMIZER DAMPER VALVE CONTROL — The economizer damper valve control maintains the difference between evaporator pressure and economizer pressure. Economizer pressure should always be higher than evaporator pressure. NOTE: If the Chiller Type (Configuration Menu Factory Parameters) is configured to Legacy, the economizer damper valve control is bypassed. When the chiller is initially powered on, or when the compressor shuts down, the damper valve will be commanded to close. These and other conditions are shown in Table 13. Table 13 — Economizer Damper Valve Status SYSTEM CONDITION ECONOMIZER DAMPER VALVE STATUS Fully closed Fully closed Fully closed Open Chiller initially powered on Compressor shut down During damper valve action delay Economizer pressure > evaporator pressure + Damper valve open DB Economizer pressure < evapora- Closed tor pressure + Damper valve close DB All other conditions Current position maintained If the damper valve has been commanded to open for a continuous 5 minutes, and the Damper Valve Full Opened condition is still not TRUE, the control system generates an alert 154. Similarly, if the damper valve has been commanded to close for a continuous 5 minutes, and the Damper Valve Full Closed condition is still not TRUE, the control system generates an alert 154. If the compressor is running and if economizer pressure becomes less than or equal to evaporator pressure, an alarm 268 will be tripped and compressor will be shut down. DEMAND LIMIT — The PIC 5 controls provide a feature for limiting AVERAGE LINE CURRENT or MOTOR KILOWATTS by limiting capacity via guide vane control/VFD control. The limit may be applied in two ways. The first is called ACTIVE DEMAND LIMIT, which is equal to a BASE DEMAND LIMIT value (set in the SETPOINT screen, default Table 14 — Override Parameters CONDENSER PRESSURE FIRST STAGE CAPACITY INHIBIT > COND PRESS OVERRIDE HIGH DEFAULT VALUE/ CONFIGURABLE RANGE 250 psig/200-260 psig SECOND STAGE CAPACITY DECREASE > COND PRESS OVERRIDE HIGH + 2.4 psi CONDENSER PRESSURE > COND PRESS OVERRIDE LOW 140 psig/90-150 psig > COND PRESS OVERRIDE LOW + 2.4 psi < COND PRESS OVERRIDE LOW CALC EVAP SAT TEMP or EVAP REFRIG LIQUID TEMP COMP MOTOR WINDING TEMP < EVAP SAT OVERRIDE TEMP* < EVAP SAT OVERRIDE TEMP - 1 F (0.56 C) > EVAP SAT OVERRIDE TEMP > COMP MOTOR 200 F/150-200 F TEMP OVERRIDE (93.3 C/65.6-93.3 C) High current override PERCENT LINE CURRENT Low discharge superheat override Low source temperature protection override Discharge Superheat (DSH) Leaving chilled water temperature (heating mode) PERCENT LINE CURRENT > 100% < DSH REQUIRED + 1 < COOLING LCW SETPOINT – 2° F (1.1° C) COMP MOTOR WINDING TEMP > COMP MOTOR TEMP OVERRIDE + 10 F (5.6 C) PERCENT LINE CURRENT > 105% OVERRIDE CONDITION High condenser pressure override (high pressure vessel/heat machine) High condenser pressure override (low pressure vessel/cool only) Low evaporator temperature override High motor temperature override OVERRIDE PARAMETER *EVAP SAT OVERRIDE TEMP = EVAP TRIPPOINT + EVAP OVERRIDE DELTA T 25 OVERRIDE TERMINATION < COND PRESS OVERRIDE HIGH COMP MOTOR WINDING TEMP < COMP MOTOR TEMP OVERRIDE – 2 F (1.1 C) PERCENT LINE CURRENT <= 100% < DSH REQUIRED – > DSH REQUIRED 3 +2 > COOLING LCW SETPOINT – 2° F (1.1° C) at any time. If the controller is replaced, one opportunity before the first start-up with the new controller is provided to set COMPRESSOR ONTIME and TOTAL COMPRESSOR STARTS to the last readings retained with the prior controller. The chiller also maintains a start-to-start timer and a stopto-start timer. These timers limit how soon the chiller can be started and are displayed on the system overview (home) and RUN TIMES screens. They can be configured in the Configuration Menu GENERAL CONFIGURATION screen. They must expire before the chiller starts. If the timers have not expired, the RUN STATUS parameter on the System Overview (Home) and GENERAL PARAMETERS screen reads TIMEOUT. WATER PUMPS CONTROL (FREEZE PREVENTION) NOTE: In order to energize the chilled and condenser pump to prevent evaporator and condenser tube freeze-up, the hydraulic system should be enabled first (this can be configured in the Configuation Menu FACTORY PARAMETERS screen). Evaporator Freeze Prevention —When the evaporator saturated refrigerant temperature or evaporator refrigerant temperature is less than the EVAP REFRIG TRIPPOINT + REFRIG OVERRIDE DELTA T (configurable from 2° F to 5° F (1.1° C to 2.8° C) in the Configuration Menu PROTECTIVE LIMIT CONFIG screen), an OVERRIDE—LOW EVAP REFRIG TEMP event will occur. For any running status, Protective Limit Alarm State 261 will be displayed and the unit will shut down if either of the following conditions is true: • Evaporator saturated refrigerant temperature or evaporator refrigerant temperature is equal to or less than the EVAP REFRIG TRIPPOINT (33 F [0.6 C] for water, (configurable for brine in Configuration Menu PROTECTIVE LIMIT CONFIG screen) plus 1° F (0.56° C). • Leaving chilled water temperature or entering chilled water temperature is less than EVAP REFRIG TRIPPOINT plus 1° F (0.56° C). NOTE: If the chiller is in recycle mode, it will transition to TRIPOUT, and the CHILLED WATER PUMP will remain on. The alarm will be clearable when the evaporator saturated refrigerant temperature, evaporator refrigerant temperature, leaving chilled water temperature, and entering chilled water temperature rise 5° F (2.8° C) above the EVAP REFRIG TRIPPOINT. Condenser Pump Control —The chiller will monitor the condenser pressure and may turn on the condenser pump. If the condenser pressure is greater than or equal to the COND PRESS OVERRIDE, and the entering condenser water temperature is less than 115 F (46.1 C), the condenser pump will energize to try to decrease the pressure and alert 157 will be generated. The pump will turn off when the condenser pressure is 3.5 psi (24.1 kPa) less than the pressure override and the condenser refrigerant temperature) is less than or equal to the entering condenser water temperature plus 3° F (1.7° C). NOTE: COND PRESS OVERRIDE is found in the Configuration Menu PROTECTIVE LIMIT CONFIG screen. The default value is 140 psig (965 kPa) for low pressure condenser and 250 psig (1724 kPa) for high pressure condenser. Condenser Freeze Prevention — This control helps prevent condenser tube freezing by energizing the condenser pump relay. The PIC 5 module controls the pump and, by starting it, helps to prevent the water in the condenser from freezing. When the chiller is off and condenser saturated refrigerant temperature is less than or equal to the condenser freeze point, the condenser water pump will be energized (Alarm State 262, PROTECTIVE LIMIT - CONDENSER FREEZE). The fault state will clear and the pump will turn off when the condenser saturated refrigerant temperature is more than 5° F (2.7° C) above the condenser freeze point and the entering condenser Other types of override events do not override control guide vane or VFD operation, but are reported: • High compressor discharge temperature override — If the COMP DISCHARGE TEMP is greater than the COMP DISCHARGE ALERT threshold, then high discharge temperature override will be displayed in the main screen until the COMP DISCHARGE TEMP is less than the COMP DISCHARGE ALERT threshold – 2° F (1.1° C). • High compressor bearing temperature override — If a compressor bearing temperature is greater than the compressor bearing temperature Alert (Configuration Menu Protective Limit Config) threshold, then High Bearing Temp Override shall be set to TRUE until all of the compressor bearing temperatures are less than Comp Bearing Temp Alert minus 2° F (1.1° C). RECYCLE CONTROL — The chiller may cycle off and wait until the load increases to restart when the compressor is running in a lightly loaded condition. This normal cycling is known as “recycle.” In cooling mode, a recycle shutdown is initiated when either of the following conditions is true: • Leaving chilled water temperature (or entering chilled water temperature, if the EWT CONTROL OPTION is enabled) is more than 5° F (2.8° C) below the CONTROL POINT. • Leaving chilled water temperature (or entering chilled water temperature, if the EWT CONTROL OPTION is enabled) is below the CONTROL POINT, and the chilled water temperature difference is less than the RECYCLE SHUTDOWN DELTA T. In heating mode, a recycle cycle shutdown occurs when either of the following conditions is true: • Leaving condenser water temperature (or entering condenser water temperature, if the EWT CONTROL OPTION is enabled) is more than 5° F (2.8° C) below the CONTROL POINT. • Leaving condenser water temperature (or entering condenser water temperature, if the EWT CONTROL OPTION is enabled) is above the CONTROL POINT, and the condenser water temperature difference is less than the RECYCLE SHUTDOWN DELTA T. NOTE: Recycle shutdown will not occur if the CONTROL POINT has been changed by more than 1° F (0.56° C) within the previous 5 minutes of operation. When the chiller is in RECYCLE mode, the chilled water pump relay remains energized so the chilled water temperature can be monitored for increasing load. The recycle control uses RECYCLE RESTART DELTA T to check when the compressor should be restarted. In cooling mode, the compressor will restart when the leaving chilled water temperature (or entering chilled water temperature, if the EWT CONTROL OPTION is enabled) is greater than the CONTROL POINT plus the RECYCLE RESTART DELTA T for 5 consecutive seconds. In heating mode, the compressor will restart when the leaving condenser water temperature (or entering condenser water temperature, if the EWT CONTROL OPTION is enabled) is less than the CONTROL POINT minus the RECYCLE RESTART DELTA T for 5 consecutive seconds. RUNNING TIMERS AND COUNTERS — The PIC 5 control maintains two run-time clocks: COMPRESSOR ONTIME and SERVICE ONTIME. COMPRESSOR ONTIME indicates the total lifetime compressor run hours. SERVICE ONTIME is a resettable timer that can be used to indicate the hours since the last service visit or any other event. A separate counter tallies compressor starts as TOTAL COMPRESSOR STARTS. All of these can be viewed on the RUN TIMES screen. Both Ontime counters roll over to 0 at 500,000 hours. Manual changes to SERVICE ONTIME from the screen are permitted 26 PIC5 control system to allow PIC5 control for the water pumps and cooling tower fans (high speed and low speed). The cooling tower fans are controlled by the pressure difference between condenser and evaporator and entering water temperature of condenser. The objective is to maintain the entering condenser water temperature in the optimal range. HEAD PRESSURE CONTROL — If the chiller system is equipped with a head pressure control valve, and the HEAD PRESSURE VALVE option in the CONF_OPT table is ENABLED, the PIC5 control system will control the opening of the head pressure valve to maintain the pressure difference between condenser and evaporator. The output of this valve is 4 to 20 mA type. Before using this function, the pressure difference values for 20 mA and 4 mA should be set. The head pressure valve should be in fully closed position when chiller is in OFF mode. ICE BUILD OPTION — The PIC5 controller provides an ice build option based on efficiency improving point. The ICE BUILD OPTION in the CONF_OPT table should be set to ENABLED to make ice build active, and the following two parameters should be configured: • Ice_recy (ICE BUILD RECYCLE) indicates whether recycle option is enabled in ice build mode. • Ice_term (ICE BUILD TERMIN SOURCE) indicates how the ice build is terminated. There are three types: temperature (0), dry contact (1), or combined temperature and dry contact (2). TIME SCHEDULE — The PIC 5 control provides three schedules: • Local schedule - OCCPC01S • Ice build schedule - OCCPC02S • Network schedule - OCCPC03S Each schedule has 8 time segments. If two time segments overlap, the unoccupied time segment takes priority. There are 16 holiday time segments. Each holiday time segment is determined by three parameters—month, start date, and holiday days. The controller will be in unoccupied mode when a holiday time segment is active. BLACK BOX — The black box task continuously stores operation parameters in memory every 5 seconds. Up to 20 collects can be stored before a chiller operation alarm event to avoid filling the buffer unnecessarily. Each collect contains up to 180 records (15 minutes), with 168 records (14 minutes) before the alarm event and 12 records (1 minute) after the event. The black box task uses the “rotary” rule to fill the records in the buffer (first in first out). Each record is associated with a time in hour, minute, and second. When 12 records have been collected after the process alarm event, the black box task stops the collect, transfers the information into a .csv file, and starts to fill another event record. The RAM memory writing is never stopped, so if another alarm event occurs there is no data loss. (If power is lost, only the .csv files remain. Data in RAM memory is lost.) The black box file can be uploaded with the Carrier S-Service tool. Once the upload is done, the data collect erase flag will be sent from the Carrier S-Service and the collect buffer will be erased. PRESSURE TRANSDUCER CALIBRATION — The HMI pressure readings are displayed in the Main Menu Pressures screen. See Fig. 36 and 37. water temperature is greater than the condenser freeze point. If the chiller is in recycle shutdown mode when the condition occurs, the controls will transition to a non-recycle shutdown. CONTROL TEST — This feature allows the operator to quick-test the controls and related hardware, including all unitcontrolled outputs except compressor output. The unit must be off to run the test function. If the unit is on, the test function cannot be accessed. The compressor can only be started after the control test is finished (QCK_TEST = FALSE). The test function also requires the user to enter the User password if it has not already been entered. All control test parameters are accessible through the QCK_TEST table. To perform the control test function, set the first item Quick Test Enable in the QCK_TST table to Enable. Unless otherwise noted, all protective limits remain active during the controls test. Discrete Outputs — When the control test is enabled, discrete outputs can be enabled by setting the corresponding points to Yes in the QCK_TST table. NOTE: The following outputs cannot be enabled at the same time Guide Vane Increase and Guide Vane Decrease are enabled: HGBP Valve Open and HGBP Valve Close; Economizer Damper Valve Open and Economizer Damper Valve Close. NOTE: For oil pressure, a value 18 psi within 40 seconds after the oil pump is turned on indicates a confirmation of pressure (Oil Pres Test Passed=YES). Analog Output — When the control test is enabled, the following analog outputs can be enabled by entering the positions in the QCK_TST table: • Head Pressure Valve • Diffuser Actuator • Chiller Status Output (Q_CHST) Guide Vane Calibration — The guide vane position should be calibrated before starting the chiller. Guide vane calibration can be started by setting Quick Test Enable to Enable and GV1 Calibration Enable to Enable. If the actuator type is digital (POS) 0, then: • The fully closed guide vane feedback resistance will be in the range of 62.5 ohms to 688 ohms (350 ± 75 ohms target setting). • The fully opened guide vane feedback resistance will be in the range of 6190 ohms to 11,496 ohms (10,000 ohms target setting). If the actuator type is analog (1): • The fully closed guide vane feedback mA value will be in the range of 3 mA to 5 mA. • The fully opened guide vane feedback mA value will be in the range of 19 mA to 20.8 mA. SWIFT RESTART — This function is used for data center applications. It allows the chiller to be restarted swiftly to meet building load requirements. To enable this function, the AUTO RESTART OPTION point in the CONF_OPT table should be set to ENABLE. The water flow verification time, oil prelube time and other delays will be decreased accordingly. If the control system and oil system are equipped with UPS (uninterrupted power supply), the start-up time will be decreased accordingly. COOLING TOWER CONTROL — If WATER PRESSURE OPTION in the CONF_OPT table is set to ENABLED, there will be another optional hydraulic control I/O board in the 27 PRESSURE - Pressures Pressure Sensor Calib Fig. 36 — PRESSURE Screen, Page a19-2233 1 a19-2236 Fig. 39 — Pressure Sensor Calib Screen, Page 2 PRESSURE - Pressures 2. Each transducer is supplied with 5 vdc from the IOB. Calibration is done by selecting the appropriate Pressure Sensor option on the Pressure Sensor Calib screen. The screen for the selected option is displayed. Figure 40 shows the Evap Pressure Sensor screen as an example. PRSCAL01 - Evap Pressure Sensor a19-2234 Fig. 37 — PRESSURE Screen, Page 2 Once a year the pressure transducers should be checked against a pressure gage. Attach a set of accurate refrigeration gages to the tranducer being checked and compare the two readings. If there is a difference the transducer can be calibrated as described below (the Oil Pump Delta P reading should be zero when the compressor is off). Calibration requires Service level access to the HMI. NOTE: It is usually not necessary to calibrate at initial start-up unless chiller is at high altitude. 1. Go to Main Menu Maintenance Menu Pressure Sensor Calib. See Fig. 38 and 39. a19-2237 Fig. 40 — Evap Pressure Sensor Screen 3. With the transducer at atmospheric pressure (zero gage pressure), ensure that “Calib Press1 (0 PSI)” = 0 PSIG. 4. Pressurize the transducer to a known pressure between 100 and 250 psig, and enter that known pressure in the “Calib Press2 (100-250PSI)” field. 5. Set Calibration Enable to Enable. Calibration for this sensor is complete and the new slope and intercept will be used for the calibrated transducer in the pressure or temperature tables. ALARM EMAIL — The alarm email function sends automatic email messages to specified service personnel for remote maintenance purposes. Use the service configuration table EMAILCFG, available from page 2 of the Configuration menu, to set up the email function. After the EMAILCFG table configuration is done, a test email will be sent. See Fig. 41-43.

At each alarm task run time, the status change of each alarm is checked and one email message is sent to each specified recipient when one or more alarms are switched on. When all alarms return to normal, another e-mail message is sent to remote maintenance service personnel. The e-mail message provides the unit description and location stored in the CTRL_ID table, available from the CONFIGURATION menu. See Fig. 44. a19-2228 Fig. 46 — Prognostics Config Screen, Page 2 The following functions are available if the Prog Function Enable option is set to YES (prog_en=YES): Oil Change Notification — The lubrication oil should be changed periodically in order to keep the appropriate lubrication for the motor and compressor. Once the period set in the Oil Change Duration field is expired, a statement is displayed to warn the user “to replace the oil charge or confirm the additive level is adequate and has not depleted.” After correction items have been finished, set the Oil Charge Completed option to YES manually. 29 Oil Filter Alert — This function is active only in an oil pump control test. If the oil pump is forced to ON and after 10 seconds, if the pressure differential between oil pump pressure and oil discharge pressure is lower than the threshold set in the Oil Filter Pres Diff field, the filter needs to be replaced and the dedicated alert 160 is reported until the oil pressure differential is higher than the alert threshold plus 2 psig. Then set the Oil Filter Change Done option to YES manually. Refrigerant Transducer Calibration — When the unit is offline for more than 5 minutes, a comparison is made of the evaporator, condenser, and economizer refrigerant pressure transducers. A difference of more than the configurable threshold set in the Trans Calib Threshold option generates an alert 161 that a calibration is required. The comparison is done for all of the transducers. After calibration, set the Trans Calibration Done option to YES manually. Low Refrigerant Charge — This function uses the evaporator approach (Evap Design Approach) setting and compressor discharge temperature (Bearing Degradation) setting in relation to the condenser refrigerant temperature (Low Charge Cond Approach) setting to generate an alert 162 of possible low refrigerant charge. After correcting the charge, set the Refrigerant Charge Done option to YES manually. MASTER SLAVE CONTROL — This control, available from page 2 of the Configuration Menu, provides the capability to operate 2 chillers in Master/Slave mode. The slave chiller should be set to NETWORK mode and controlled by the master chiller. The two chillers can be configured to be in parallel or in series. When they are in series mode, master and slave chillers can be configured to be upstream or downstream. The master chiller monitors all external commands, such as start/stop, demand limiting, or setpoint configuration. The master/slave function provides the ability to select a lead chiller from the master and the slave chillers. Selection is based on the delta between the master and the slave run hours, and tries to optimize the runtime hours. If this function is not set, the lead chiller is always the master chiller and should be changed to lag when it fails. The lead chiller shall always be started first, and the lag chiller shall be maintained at zero percent capacity. When the lead chiller cannot be loaded anymore, then the lag start timer is started. The lag chiller shall always be stopped first. If a communication failure is detected between the master and the slave chillers, all master/slave functions are disabled and chillers return to stand-alone operations until communication is reestablished. Trendings Fig. 47 — Data Logging and Trending Screen Set-Up Page Trendings Fig. 48 — Data Logging and Trending Screen Display Page DIAGNOSTICS AND TROUBLESHOOTING The 19XR PIC 5 control system has many fault tracing aid functions. The local interface and its various menus give access to all unit operating conditions. If an operating fault is detected, an alarm is activated. The alarm code is displayed in the Alarms menu, sub-menus Reset alarms and Current alarms. The control may record up to 10 current alarms. Displaying Alarms — The alarm icon on the interface (see the section Icons on page 17) indicates unit status as follows: • A flashing LED shows that the unit is operating but there is an alert. • A steady LED shows that the unit has been shut down due to a fault. The Reset Alarms option on the main menu displays up to five alarm codes that are active on the unit. Table 15 lists alarm codes. The Current Alarms option displays details for each alarm. Displaying Data Trends — The PIC 5 control system offers the ability to configure and display system trends wiwthout a password. Select Main Menu Trendings. On the Trendings screen (see Fig. 47), check the data to be tracked. Set the beginning and end points for the selected data. To change a color, select the colored square and choose a new color from the pop-up color bar. To view data trends, select the down arrow at the bottom right of the Trendings screen. The next page displays the selected data in the chosen colors. See Fig. 48. Resetting Alarms — When the cause of the alarm has been identified and corrected, the alarm can be reset either automatically or manually (depending on the type of alarm). Alarms can be reset without stopping the machine. In the event of a power supply interrupt, if Auto Restart Option is set to ENABLE in the Option Configuration menu, the unit restarts automatically without the need for an external command. However, any faults active when the supply is interrupted are saved and in certain cases may prevent a unit from restarting. 30 A manual reset must be run from the main menu via the ALARMRST menu, item RST_ALM. Once the alarm has been corrected or reset, all information regarding solved alarms is stored in the Alarm History. See Appendix A, page 94. Alert Codes — Table 16 lists PIC 5 alert codes. These are automatically reset when the situation returns to normal.

If possible, uncheck “use of an automatic configuration script.” Restart the web browser. Ethernet network is not available. While accessing the unit via the Proxy server problem in the local web browser, the Java platform network. launches, but remains blocked. No file is loaded. Contact your system administrator. The application has been launched, but the screens are not shown in the web browser. Check that the web browser does not go via a proxy server to access the unit. Check that the Java application does not store the internet files on the PC. A proxy server is used to access the unit and this supplies the old screens to the browser. Incorrect configuration of the Java application. NOTES: 1. The unit cannot automatically obtain the network parameters via a DHCP (Dynamic Host Configuration Protocol) server. Open the browser and in the system connection parameters add the IP address of the unit in the proxy exceptions. (ToolsOptions ConnectionSystem parameters“No proxy for”). See the section Java Application Configuration on page 57. 2. The intranet site address of the unit is the IP address. 55 In the example shown in Fig. 63, the PC receives four negative responses (request timed out). Troubleshoot these with the following methods: UNIT IS POINT-TO-POINT CONNECTED TO A PC — The cable can be either crossed or uncrossed, and the unit is energized. NOTE: In addition to the following procedure, it may be necessary to check the Ethernet connection and/or configure the PC network board. In Network Settings, open Local Area Connection Properties. Select Internet Protocol and click Properties. See Fig. 61. Ethernet/IP Connection Problems — a30-5861 Fig. 63 — Ping — Negative Responses If the PC receives four negative responses, check the internet browser parameters to determine if a proxy server or an automatic configuration script has been configured. If this is the case: • Deselect the proxy server or the configuration script and restart the browser, • Or refer to the section Java Application Configuration (page 57). Try to access the unit again. If the PC still does not receive a response from the unit, restart the unit. Contact your system administrator. UNIT IS CONNECTED TO THE LOCAL NETWORK — The unit is connected to the local network by an uncrossed cable, and the unit is energized. Open a Windows command window (Start, Execute, type cmd and press Enter), then type the command ping, followed by the unit IP address. If the responses are positive (see Fig. 62), the internet browser configuration is faulty. Check the system parameters of the internet browser to determine if a proxy server or an automatic configuration script has been configured (Tools Internet Options Connections System Parameters). See Fig. 64. SELECT a30-5898 Fig. 61 — Local Area Connection Properties The Internet Protocol Properties window is displayed. • If no IP address is configured in the General and Alternative Configuration tabs, the unit IP address must be configured to 169.254.xxx.xxx. Modify the unit IP address and then restart the system. • If the PC has a fixed IP address configured in one of the two tabs (General and Alternative Configuration), the IP address of the PC and the unit IP address must have the system and sub-system fields in common. The last part of the IP address is the host number and must be unique on the sub-system. For example: Unit address — 172.30.101.11 and PC address — 172.30.101.182. In this example, 172.30 corresponds to the network, and 101 corresponds to the sub-system. Carry out the necessary modifications and try to access the unit again. If there is still a problem, open a Windows command window (Start, Execute, type cmd and press Enter), then type the command ping, followed by the unit IP address. In the example shown in Fig. 62, the PC receives four positive responses (replies). 1 2 3 1 2 3 — — — LEGEND Automatic configuration script Proxy server Advanced proxy configuration a19-2174 Fig. 64 — Local Area Network Settings If a proxy server is used, add the unit IP address to the exceptions list of the proxy server (advanced proxy configuration).

Select a direct connection to bypass the proxy server or select the automatic configuration script. See Fig 67. Fig. 65 — Proxy Settings a19-2175 If a configuration script is used, it is not possible to add the unit IP address to the exceptions list. In this case, see the section Java Application Configuration below. If the response to the “ping” command is negative, verify the IP address of the PC and the IP address of the unit. They must have the system network and sub-system in common. The last part of the IP address is the host number and must be unique on the sub-system; for example: Unit address — 172.30.101.11 and PC address — 172.30.101.182. In this example, 172.30 corresponds to the system network, and 101 corresponds to the sub-system. The host numbers are 11 and 182 respectively. ETHERNET CONNECTION ON THE PC — Open the network configuration window of the PC and double-click Network Connections. Find the system interface board and check that no red “X” appears on the icon. The connection to the local network must be authorized and in the connected status. If this is not the case, check the connections and authorize/repair the network connection. JAVA APPLICATION CONFIGURATION — Open the Internet configuration window of the PC and double-click the Java application icon. If Java is not installed, a free download is available at http://www.java.com. If Java has already been installed, check if it is used by other applications. If so, check that these are compatible with the following settings in the Java control panel.

See Fig. F. a19-2130 Fig. F — HMI Access Cover 96 APPENDIX C — INPUT/OUTPUT BOARD (IOB) STATUS INDICATORS • Microprocessor operational and communicating with control system: LED flashes at 0.5 Hz rate (1 second on, 1 second off) in sync (±100 ms) with all other new control modules on the same communication bus • Microprocessor in boot mode: LED flashes at 0.2 seconds on, 0.2 seconds off) Each independent communication port has a green status LED. The green LED is on when data is being transmitted by the board. All control boards have LED indicators that show control board and communication status. A red LED on each control module operates in the following manner: • Power not present or power supply failure: LED is off • Power present but microprocessor in Reset: LED is off • Microprocessor operational but not communicating: LED flashes 3 seconds on, 3 seconds off 97 APPENDIX D — BACnet OPTION General — The 19XR PIC 5 controller supports the BACnet protocol as B-ASC BACnet equipment over IP. In addition, BACnet on the PIC 5 controller supports the following features: • Optional properties such as Change of Value (COV), Intrinsic Reporting, and Commandable properties on some objects. • The generation of limited alarm and event notifications and the ability to direct them to recipients • The tracking of acknowledgments of alarms from human operators • The adjustment of alarm parameters • Read/write property for many services Installing the BACnet Dongle — The BACnet op- tion can be implemented at the factory or on-site. This section is intended for on-site installation. It is strongly recommended to disconnect the complete power supply before any intervention. Disconnect the main power supply with appropriate disconnect devices. Only personnel qualified to the level recommended in standard IEC 60364 (International Electrotechnical Commission) and trained to do this may have access to electrical components. a19-2262 Fig. I — Cover Removed 3. Insert the BACnet dongle into the connector. See Fig. J. CAUTION The components that make up the chiller controller include electronic components. These may generate or be damaged by electromagnetic interference such as electrostatic discharge (ESD). Technicians who do not have access to an ESD wrist strap on site should follow these recommendations in order to minimize the risk of ESD: • Be sure to be at zero potential by touching an unpainted surface on the electrical box. • Do not wear clothing that tends to conduct electrical charge, such as a wool sweater. • Electrical storms can increase the ESD risk; unless absolutely necessary, do not work on the chiller controller during an electrical storm. a19-2263 Fig. J — Inserting BAcNET Dongle MOUNTING THE BACNET DONGLE — Follow these steps to mount the BACnet dongle in the PIC 5 control box: 1. Disconnect the PIC 5 control power supply. 2. Open the metal cover of the control box with a screwdriver. See Fig. H and I. 4. Mount the plastic holder that holds the dongle to the board. See Fig. K. a19-226 a19-2261 Fig. K — Mounting Plastic Holder Fig. H — Opening Cover 5. Close the box and power up the PIC 5 controller. 98 APPENDIX D — BACnet OPTION (cont) Alarm states are coded as shown in Table B. TESTING THE INSTALLATION — To verify that the dongle connection is correctly inserted and detected by the equipment, with the controller powered up, go to the PIC 5 Main Menu nputs Status and confirm that the BACnet Dongle status is Yes. Table B — Alarm States BACNET CODE 0 1 2 BACnet Settings — BACnet settings are available on the Main Menu Configuration Menu BACnet Config. The menu requires the Advanced User password for access. For details, see the Bacnet Config table on page 79. Modifying the Unit IP Address — Note that changing IP address from the PIC 5 SETUP menu will require a manual reboot or power cycle of the PIC 5 controller in order to re-build the BACnet stack. For detailed instructions, see the Unit IP Address section on page 52. BACnet Objects — The 19XR PIC 5 contains up to 500 BACnet objects. They can be of ANALOG_VALUE (AV) or BINARY_VALUE (BV) type. Objects name are built from CCN table name and CCN point name concatenated in order to recognize them easily. For a detailed list, see the BACnet Points table beginning on page 100. In general, the equipment configuration parameters are available as Read Only. Set point parameters are available in Read-Write access. Compressor status is ASCII-coded. In order to obtain the status from BACnet, statuses are assigned a BACnet code as shown in Table A. BACnet IP Communication Problems — If the unit does not respond to the building management system, possible causes include the following: • The BACnet dongle is not detected by the chiller application. • The Ethernet cable is not correctly connected. • Network parameters are not correct (see the Ethernet/IP Connection Problems section on page 56). • There is an IP router between the equipment and the buildign management system. • BACnet Enable parameter in the PIC 5 Configuration Menu is set to No. To troubleshoot problems, try these measures: • Open the metal casing of the 19XR PIC 5 controller and verify that the blue BACnet dongle is correctly connected. • On the Ethernet connector, verify that the green LED is ON and the orange LED is blinking • Open a command window under Windows (Start, Execute, type cmd and press Enter), type the command ping followed by the equipment IP address. The equipment must respond. • Open 19XR PIC 5 Configuration Menu (Service password required) and check BACnet parameters. • Use the free software called BDT (BACnet Discovery Tool) available on the internet (search bacnet bdt) and install it on the PC. All equipment connected to the BACnet network will respond to the “Who Is” command sent by this tool. Find the equipment configured with the BACnet device instance (1600001 for Carrier equipment).

Diagnostics and troubleshooting
To start the chiller, select the desired operating mode (LOCAL, LOCAL SCHEDULE, REMOTE, or NETWORK) and press the 'Local ON' button on the PIC 5 interface screen. Follow the on-screen instructions to complete the startup sequence.
The chiller has four operating modes: LOCAL, LOCAL SCHEDULE, REMOTE, and NETWORK. The mode determines how the chiller is started and stopped, whether it's controlled locally, through a schedule, remotely, or via a network connection.
You can access the control panel through the PIC 5 Human Machine Interface (HMI), a color 10.4 in. TFT touch screen. You can also connect to the control panel via a web browser through the Ethernet IP port on the controller.
How to switch the AquaEdge 19XR chiller to REMOTE or NETWORK control mode via CCN?
On the PIC 5 'Unit Start/Stop' screen, select 'Off' and choose 'REMOTE' or 'NETWORK' from the list. In NETWORK mode, the unit is controlled via the Carrier Comfort Network (CCN) using software points like CHIL_S_S for start/stop commands.
