2.1.4.2.2. REDUCED MODE

Reduced mode can have the following configurations:

² Overcooling This function is only available if the unit is in cool mode. It can cool the building at night when electricity is less expensive.

² Eco The heating setpoint is reduced in heat mode and the cooling setpoint is higher in cool mode.

² Low noise Noise reduction by limiting the speed of the fan if possible. For this, the pressure setpoints are increased in cool mode and reduced in heat mode

² Eco + Low noise

2.1.4.2.3. LOAD SHEDDING

Load shedding is occasionally used to limit the electricity consumption of the SysAqua to prevent exceeding the electric power capacity of the installation site.

The electricity consumption is limited by limiting the thermodynamic capacity of the SysAqua.

The "Load shedding" mode activation can be triggered in the following ways:

² directly on the SysAqua via the user interface

² communication network (Modbus/Bacnet/Cloud)

² external dry contact if entry configured

Engl

ish

So that the mode indicated in the calendar is activated, the unit must operate in "Automatic" mode.

InformationWhen the pump is started (shutdown -> on), the speed of the pump will be equal to the value of speed parameter "Var pump.max.speed" for 30s.

13SysAqua

By setting this parameter you can ask the pump to work continuously when the unit is supplied.A protective system for the pump is activated by default in the SysAqua. This involves starting up the pump for a period of 60 seconds if the latter has not operated for 72 hours. This operation is repeated every 72 hours if no starting of the pump is detected during this period.

This function enables any seizing of the pump to be prevented.

2.2.2.2. PUMP MANAGEMENT

The speed of the variable pump depends on the current capacity of the unit.

If the capacity equals 0, the pump will operate at the speed specified by the "Var pump.speed.old" parameter. As soon as the capacity is greater than 0, the speed of the pump follows the linear function shown below.

This menu is used to configure the pump parameters when the SysAqua is equipped with:

² Single pump

² Double pump

² Modulating pump

2.2.2.3. CIRCUIT CONTROLThis menu is used configure the value of the timer of the evaporation low pressure alarm for each circuit.

2.2.2.4. CONFIGURATION OF REMOTE COMMANDSAn external dry contact is dedicated to switching the SysAqua on or off remotely. It can be configured in this menu as normally open or normally closed.

This menu is used to configure the different control parameters for a deicing cycle:

² DT defrost: If the air temperature is less than the heat exchanger temperature at the difference indicated, the circuit switches to deicing mode (range: [10-20K], default value 10K)

² DT defrost shutdown: If the air temperature is less than the heat exchanger temperature at the difference indicated while the circuit is in shutdown phase, the circuit switches to deicing mode (range: [10-20K], default value 7K).

² Sour.t.defr.fin.: The deicing stops when this temperature is reached by the heat exchanger sensor. (range: [12-20°C], default value 18°C).

This menu can also be used to manually force the deicing of a circuit. The unit must be operating for this to be done.

Changing the value of the relevant circuit line from No to Yes in the "Manual Deicing" heading will start the manual deicing. This deicing will stop

² If this value is set to No while the manual deicing is in progress

3. FUNCTIONS3.1. ON/OFF

SysAqua can be switched on and off in different ways:

² External input: The unit is operating if the contact is closed. Shutdown by this input has priority

² User interface: The operation can be started by the onboard or online (HMI1Web) graphic interface status menu

² GTC: the operation can be controlled by a GTC through different communication protocols (Refer to the § COMMUNICATION, page 11).

The shutdown sequence for the unit overrides the minimum operation time of the actuators. However, the operation sequence takes these times into account.

The deicing sequence has priority over the request to shutdown the unit.

The external contact has priority over the other operating modes when shutting down the SysAqua. However, if the mode is off on the user interface or GTC, the unit remains shutdown whatever the status of the external contact.

The operating of the SysAqua through the user interface has priority over a GTC shutdown request.

3.2. OPERATING MODE

This parameter is not accessible for the "Cool only" units.

If the unit is reversible, its operating mode can be defined:

� Automatic mode

� Heat mode

� Cool mode

The current mode can be viewed on the home page of the user interface as well as by the communication networks:

² Modbus: actual operating mode (0x0002)

² Bacnet: “Actual operating mode"

The mode can be selected either

² By the external contact: For this, the external contact must be configured in "Heating" mode. This can be configured in the "Service" menu via the "Configuration" screen (Refer to the § CONFIGURATION, page 12). A closed contact on this input corresponds to the heat mode, if it is

open, to the cool mode. If this contact is configured, it has priority.

² By the user interface: Go to the user menu and modify the operating mode on the relevant line.

² By the GTC: The selection is made by the remote operating mode variable (holding register: 0x0000 in modbus)

3.2.1. GENERALITY

Engl

ish

The mode defined by the user interface has priority over the mode set by the communication bus

17SysAqua

To change the operating mode by an external contact, set the SysAqua to "Cool" mode. Indeed, if the SysAqua is configured in "Heat" mode, opening the contact will not switch the unit to "Cool" mode. However, in "Cool" mode, closing the contact will switch the SysAqua to "Heat" mode.

When the Auto mode is active, weather compensation is enabled in heat and cool mode is overridden with the default values (Refer to the § WATER LAW, page 8).

3.2.2. AUTO MODE

If the Auto mode is selected, the operating mode will depend on the external ambient temperature according to a temperature setting and a hysteresis.

Parameters Min Max défautAuto mode setpoint °C 18 23 20

Auto mode hysteresis K 4 8 5

The heat and cool mode will be selected as shown on the graph below:

² If the external ambient temperature exceeds the setpoint + half the hysteresis value (22.5°C by default), the unit will change from heat to cool mode

² If the external ambient temperature falls below the setpoint - half the hysteresis value (17.5°C by default), the unit will change from cool to heat mode

3.3. REDUCED MODE

The mode can be selected either

² By the external contact: For this, the exterior contact must be configured in "reduced" mode. This can be configured in the "Maintenance" menu via the "Configuration" screen (Refer to the §

CONFIGURATION, page 12). A closed contact on this input corresponds to the reduced mode. If this contact is configured, it has priority.


² By the GTC: The selection is made by the remote operating mode variable (0x0019 in modbus)

Reduced mode enables energy savings to be made or to increase acoustic comfort.


Reduced mode can have the following configurations:

² Abais. con. froid: this function is only available if the unit is in cool mode. It can cool the building at night when electricity is less expensive.

² Eco: The heating setpoint is reduced in heat mode and the cool setpoint is raised in cool mode.

² Low noise: Noise reduction by limiting fan speed if possible. For this, the pressure setpoints are increased in cool mode and reduced in heat mode

² Eco + Low noise

If the SysAqua is configured in reduced mode by the user interface or the GTC, opening the external contact will not be considered as a reduced mode output.

However, in the other operating modes defined by the user interface or the GTC, the reduced mode selected in the configuration will be implemented when the external contact is closed and deactivated when the contact is open.

3.4. LOAD REDUCTIONThe Load reduction mode can occasionally be used to limit the electric consumption of the SysAqua to prevent the energy consumption limits of an installation from being crossed.

Electric consumption is limited by limiting the thermodynamic capacity of SysAqua by means of a modifiable parameter in the Installation menu.


The maximum percentage of reduced load capacity can be configured by the user interface in the "Installation" menu via the "Load reduction" screen.

3.4.2. ACTIVATION

The Load reduction mode can be triggered in the following ways:

² By the external contact: For this, the external contact must be configured in "Load reduction" mode. This can be configured in the "Maintenance" menu via the "Configuration" screen (Refer to the §

CONFIGURATION, page 12). A closed contact on this input corresponds to the Load reduction mode. If this contact is configured, it has priority.


² By the GTC: The selection is made by the remote operating mode variable (0x0000 in modbus)

If the SysAqua is configured in Load reduction mode by the user interface or the GTC, opening the external contact will not be considered as a Load reduction mode output. However, in the other operating modes defined by the user interface or the GTC, the Load reduction mode will be taken into account when the external contact is closed and deactivated when the contact is open.

3.5. DEICING

Each circuit of SysAqua 140/150/170/190/210 has its own deicing control. The only limitation is that one circuit is not authorized to deice if the other one is undergoing deicing and 5 minutes after the end of deicing of the first circuit.

Some deicing parameters can be accessed from the user interface:

² DT defrost: If the air temperature is less than the heat exchanger temperature at the difference indicated, the circuit switches to deicing mode (range: [10-20K], default value 10K)

² DT defrost shutdown: If the air temperature is less than the heat exchanger temperature at the difference indicated while the circuit is in shutdown phase, the circuit switches to deicing mode (range: [10-20K], default value 7K).

² Sour.t.defr.fin.: The deicing stops when this temperature is reached by the heat exchanger sensor. (range: [12-20°C], default value 18°C). when this temperature is reached by the heat exchanger sensor. (range: [12-20°C], default value 18°C)

Changing the mode cannot stop the deicing operation. Only an alarm can stop the deicing before it completes its cycle.

Deicing can be initiated in different ways:

² If the temperature delta between the air temperature and that of the heat exchanger falls below the configured value

² If the evaporation pressure drops

² Preventive deicing.

Deicing stops if the heat exchanger temperature rises above the configured value.

If the water outlet temperature drops below 10°C or if the deicing lasts more than 10 minutes, an alarm is displayed and the deicing cycle is stopped.

4. INPUTS/OUTPUTS4.1. COMPRESSORS

The compressors are activated according to a calculation of capacity calculated by proportional-integral control according to the setpoint and water outlet temperature.

The number of activated compressors depends on the required capacity. The selection of activated compressors is managed by a Lead-lag algorithm enabling the operating time of each compressor to be equalized.

4.2. FANS

The unit can control 2-speed AC fans or variable speed EC fans. The fan speed is managed by a proportional controller.

² according to the condensation pressure in cool mode

² according to the evaporation pressure in heat mode

The AC fan speed is controlled by two stages with hysteresis and the EC motor by a ramp with a hysteresis threshold for the minimum speed.

4.3. ELECTRONIC PRESSURE REDUCING VALVE SYSAQUA 140/150/170/190/210

The electronic pressure reducing valve position has several phases:

² Pre-positioning

² OperationIn pre-positioning mode, the position of the electronic pressure reducing valve depends on the water inlet temperature and the air temperature.

In operation, the position of electronic pressure reducing valve is controlled by a proportional integral controller based on overheating.

Stopping the circuit that is not in deicing mode is not authorized either during the deicing of the first circuit and two minutes after the end of deicing.

4.4. 4-WAY VALVEThe 4-way valve is powered in heating mode and not powered in cool mode.

The 4-way valve can only be deactivated in one of the two conditions

² The compressor stops for more than one minute

² The difference between the condensation pressure and the evaporation pressure is less than 4 barg4.5. CRANKCASE HEATER SYSAQUA 140/150/170/190/210

The heating resistances are powered:

² On startup of the SysAqua for a period of 30 minutes. The start of the compressors is blocked during this period. If the SysAqua is not powered during less than 3 hours, this preheating is not done.

² If one of the circuit compressors does not operate for more than 15 minutes.

4.6. PUMPFor a single or double pump, the pump operates as long as the SysAqua is not in OFF mode.

If the SysAqua has the double pump option, the operating priority will be the first motor of the pump. The first pump motor will be stopped and replaced by the second in the following cases:

² First motor issued order but no flow is detected

² Thermal security of the first motor is activated.

4.7. ANTI-FREEZE RESISTANCE

The temperatures are measured by NTC sensors.

The sensors are considered to be disconnected if the temperature is less than -40°C

The sensors are considered as having a short circuit if the measured temperature is greater than 80°C (150°C for the backflow temperature)Specific case for outside air measurement

The temperature recorded in the control is different from the measured temperature:

² In normal operation, the value recorded is the sliding average of the measured value over 5 minutes

² In deicing phase, the value recorded is the last value of the average before the start of deicing

² If the SysAqua is off, the outside temperature is not updated

² If the SysAqua was started

� and the SysAqua was switched off less than 15 minutes, so the outside air temperature is not updated

� Otherwise, this temperature is equal after 90s of fan operation

The SysAqua is shut down if the pump fails. These failures can be:

² External pump: no flow detected

² Single pump:

� Pump activated and no flow

� Thermal protection of the pump activated

² Double pump (SysAqua 140/150/170/190/210):

� Second pump motor activated and no flow

� Thermal protection of the two motors activated

4.8. THERMISTORS

This protective system can be triggered if the SysAqua is off and the water temperature drops too low. Refer to the § ANTI-FREEZE PROTECTION, page 22. for more information.

5. PROTECTIVE SYSTEMSSysAqua has several alarms to protect its components and users.

5.1. CONDENSATION PRESSUREThree alarm levels can protect the pressure circuits from condensation that is too high:

1. If the condensation pressure approaches the limit (function of the operating mode), a compressor is stopped to reduce the capacity of the SysAqua. If the pressure drops below a preset threshold, the initial calculation of the capacity is again used to manage compressors.

2. If the first protective system is not enough, the shutdown sequence of the circuit is activated if the pressure limit is reached. The circuit has an automatic reset if the pressure drops below the defined threshold.

3. If the high pressure pressure switch is activated, the circuit is immediately stopped and requires manual resetting.

5.2. EVAPORATION PRESSUREThree alarm levels can protect the pressure circuits from evaporation that is too low:

1. If the evaporation pressure approaches the limit (function of the operating mode), a compressor is stopped to reduce the capacity of the SysAqua. If the pressure rises above a preset threshold, the initial calculation of the capacity is again used to manage compressors.

2. If the first protective system is not enough, the shutdown sequence of the circuit is activated. If the pressure drops, the circuit is restarted. If the threshold of three alarms per hour is reached, the reset becomes manual.

3. If the low pressure pressure switch is activated, the circuit is immediately stopped and requires manual resetting.

5.3. BACKFLOW TEMPERATUREExcluding deicing, the second compressor stage is stopped if the backflow temperature reaches 125°C. The first stage stops at a temperature of 130°C. If the first stage stops, an alarm is activated. The reset is automatic. A manual reset is required if the alarm is triggered a second time within one sliding hour.

In deicing mode and the next 5 minutes; both compressors of the circuit are stopped if the backflow temperature reaches 130°C and restarts after at least 3 minutes if the temperature is below 100°C.

5.4. ANTI-FREEZE PROTECTIONThe anti-freeze protective system is used to prevent damage to the water circuit. This protection depends on the glycol concentration configured.

The alarm is activated if the water inlet or outlet temperature falls below the SpFrPrt value (automatically modified according to the glycol level). This alarm is automatically acknowledged if the temperature rises above 2 K at SpFrPrt in less than 5 minutes.

If a water temperature is less than SpFrPrt for more than 5 consecutive minutes, the FrPrt alarm is triggered; likewise if a water temperature drops below the LoLm value (depends on the glycol level). An acknowledgement is required to remove the alarm.

off 3°C -1°C -4°C -11°C

5.4.1. WATER FLOW/RETURN TEMPERATURE DIFFERENCE PROTECTIONThe temperature difference protective system safeguards against a sensor fault other than a disconnection or short circuit. The protective system is activated if the temperature difference between the water inlet or water outlet temperature is too high.SysAqua is shut down if the temperature difference between the water inlet and outlet becomes too great. The acknowledgement is automatic with a hysteresis of 2k.

The blocking alarm is activated if the alarm occurs 3 times in 15 minutes.

In cool mode, the unit is stopped if the water temperature is too high for more than 30 minutes.

This alarm is deactivated for the first 30 minutes the compressors are in operation.

The unit stops immediately if the flow switch opens. There is a reset after 5 minutes and an alarm is activated if the flow switch remains open 30 seconds after the restart.

This alarm cannot be activated during the first thirty seconds of operation.

If the thermal protection of a fan or pump is activated, the unit stops immediately.

If the thermal protection of a compressor is activated, only this compressor is stopped and the unit continues to operate by taking into account the shutdown of this compressor.

If the condensation and evaporation pressure are both less than 1 barg, a coolant leak is detected. The circuit is therefore locked.

5.6. FLOW SWITCH

5.7. COMPRESSOR/FAN/PUMP THERMAL PROTECTION

5.8. PUMP ANTI-SEIZURE

5.9. COOLANT LEAK

A protective system for the pump is activated by default in the SysAqua. This involves starting up the pump for a period of 120 seconds if the latter has not operated for 72 hours. This operation is repeated every 72 hours if no starting of the pump is detected during this period.

This function enables any seizing of the pump to be prevented. The activation/deactivation of this protective system and the periods defined above can be configured in the Maintenance-Configuration-Pump configuration menu.

InformationLines identified with an i notify the user about specific operating statuses of the SysAqua but are not considered as alarms.

This corresponds for instance to preheating the circuits by heating resistances or to the drop in capacity if operating limits are approached.

6. ALARMS

If at least one alarm or warning is in progress, the alarm button flashes.

Press the 'Alarm' button to access the latest current alarm. The screen displays the latest alarm activated with a description, the date and time at which it occurred.

If the list of alarms is displayed, pressing the "Alarm" button takes you to the alarm history. Here again, the detail of the alarms can be displayed (max. 50).

Pressing the button a second time gives access to the list of alarms and warnings that are currently active. You can scroll the alarm list and obtain details by clicking on the "Enter" button. To exit the alarm detail and return to the alarm list menu, press the "Escape" button.

The first "Remove" line is used to remove alarms that are not active but require acknowledgment. To do this:

² Ensure that you have an "installation" or "maintenance"' access level

² select this line, validate and select "Execute".

The number on the first line shows the number of alarms or warnings that are currently active.

In the alarm history, a line beginning with a + identifies when an alarm or a warning is activated. A line beginning with a - shows that the alarm or warning was reset or acknowledged.
