2.1.4.2.2. REDUCED MODE
Reduced mode can have the following congurations:
²Overcooling
This function is only available if the unit is in
cool mode. It can cool the building at night when
electricity is less expensive.
²Eco
The heating setpoint is reduced in heat mode and
the cooling setpoint is higher in cool mode.
²Low 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
²Eco + 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:
²directly on the SysAqua via the user interface
²communication network (Modbus/Bacnet/Cloud)
²external dry contact if entry congured
English
So that the mode indicated in the calendar is activated, the unit must operate in "Automatic" mode.

2.1.4.2.5. COMMUNICATION
The SysAqua can also be connected in Modbus mode via an RTU
(RS485) or IP link. In the event of RTU conguration, the format of
the modbus frame, the transmission speed and the slave address
can also be accessed by this menu.
ETHERNET
The Ethernet conguration screen congures the various parameters
of the SysAqua to connect to a corporate network.
IP communication enables a connection to the SysAqua from a
computer found on the same network. This connection sets up a
remote access to the user interface.
MODBUS
BACNET IP
BACNET MSTP
LON
CLOUD
Only the communication protocols available in the conguration of your SysAqua will appear in the
communication conguration menu.
In this menu, the conguration of the various IP parameters of the
BACnet IP port such as the name, the unit number, the BACnet port
and the language is possible.
The different parameters, communication speed, address, name, unit
number, Bacnet port and the language dening the communication
protocol of the BACnet MSTP port can be congured via this menu.
The different communication parameters of the LON protocol such
as the PIN service, the ID neuron, the nodes and the unit status can
be accessed by this menu.
This menu can activate or deactivate the Cloud service as well as
view the status.
WEB USER INTERFACE (HMI4WEB)
If the unit is connected to the IP network, all the elements of the interface can be found on the screen of
your computer.
To do this, you must
²open up your Internet browser
²enter IP address of the appliance in the address bar xxx.xxx.xxx.xxx
²Enter the identier and the HMI4Web password
²After validating, an interface containing the same elements as the user interface of the machine is
displayed on your screen.

Information
When 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 specied 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 congure the pump parameters
when the SysAqua is equipped with:
²Single pump
²Double pump
²Modulating pump
2.2.2.3. CIRCUIT CONTROL
This menu is used congure the value of the timer of the evaporation low pressure
alarm for each circuit.
2.2.2.4. CONFIGURATION OF REMOTE COMMANDS
An external dry contact is dedicated to switching the
SysAqua on or off remotely. It can be congured in this
menu as normally open or normally closed.
The second can be congured with the function values
dened below.
²None
²Low load
²Heating
²Reduced
Giving priority to these external dry contacts with respect to modes dened through the user interface
where communication is specied in in § FUNCTIONS, page 16.

The maintenance menu can manually control the following
actuators:
²Circuit 1 and circuit 2 fan
²Circuit 1 and circuit 2 electronic pressure reducing
valve
²Circuit 1 and circuit 2 cycle reversal valve
²Pump
The compressors cannot be activated manually for safety
reasons.
To activate an actuator manually, switch from "Automatic"
to "Manual" mode then select the required status.
If the unit has the all season option (TTS), the fan rotation speed can be set manually in the 0-100% range.
Apply the following setting for the fan to test:
1. Manual
2. Stage 1
3. Manual
4. Select the required fan speed

2.2.2.5. WATER FLOW/RETURN TEMPERATURE DIFFERENCE PROTECTION
The 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. (Refer to the § WATER FLOW/RETURN
TEMPERATURE DIFFERENCE PROTECTION, page 22)
English
Information
The operating mode for a deicing cycle is described in in § DEICING, page 20.

This menu is used to congure the different control parameters for a deicing cycle:
²DT 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)
²DT 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).
²Sour.t.defr.n.: 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
²If this value is set to No while the manual
deicing is in progress
²Or according to the usual conditions
for stopping the deicing (Refer to the §
DEICING, page 20)
If the deicing stops according to the usual conditions, set the manual deicing value from "Yes" to
"No".

3. FUNCTIONS
3.1. ON/OFF
SysAqua can be switched on and off in different ways:
²External input: The unit is
operating if the contact is closed.
Shutdown by this input has
priority
²User interface: The operation
can be started by the onboard
or online (HMI1Web) graphic
interface status menu
²GTC: 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 dened:
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:
²Modbus: actual operating mode (0x0002)
²Bacnet: “Actual operating mode"
The mode can be selected either
²By the external contact: For this, the external contact must be congured in "Heating" mode.
This can be congured in the "Service" menu via the "Conguration" 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 congured, it has priority.
²By the user
interface: Go
to the user menu and modify the operating mode on the
relevant line.
²By the GTC: The selection is made by the remote operating
mode variable
(holding register: 0x0000 in modbus)
3.2.1. GENERALITY
English
The mode dened by the user interface has priority over the mode set by the communication bus
Caution
During a change of mode when the compressors are operating, the compressors must be stopped
for a period of 10 minutes before activating the new mode.

17SysAqua
To change the operating mode by an external contact, set the SysAqua to "Cool" mode. Indeed, if the
SysAqua is congured 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 défaut
Auto 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:
²If 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
²If 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
²By the external contact: For this, the exterior contact must be congured in "reduced" mode.
This can be congured in the "Maintenance" menu via the "Conguration" screen (Refer to the §
CONFIGURATION, page 12). A closed contact on this input corresponds to the
reduced mode. If this contact is congured, it has priority.
²By the user
interface: Go
to the user menu and modify the operating mode on the
relevant line.
²By 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.
3.3.1. CONFIGURATION
Reduced mode can have the following congurations:
²Abais. 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.
²Eco: The heating setpoint is reduced in heat mode
and the cool setpoint is raised in cool mode.
²Low noise: Noise reduction by limiting fan speed
if possible. For this, the pressure setpoints are
increased in cool mode and reduced in heat mode
²Eco + Low noise
If the SysAqua is congured 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 dened by the user interface or the GTC, the reduced mode selected
in the conguration will be implemented when the external contact is closed and deactivated when the
contact is open.
