1 - SAFETY CONSIDERATIONS
EN-5 AQUACIATPOWER

2.1 Control system
AQUACIATPOWER chillers and heat pumps are equipped with
the CONNECT TOUCH control that serves as a user interface
and a configuration tool for controlling the chiller / heat pump
operation.
AQUACIATPOWER LD-ST chillers and AQUACIATPOWER ILD-ST
heat pumps are typically equipped with fixed speed fans, whereas
AQUACIATPOWER LD-HE chillers and AQUACIATPOWER ILD-HE
heat pumps use variable speed fans which reduce the unit energy
use during occupied and unoccupied periods, provide condensing
and evaporating pressure control and smooth fan start. The system
may also control fixed speed pumps or variable speed pumps with
a hydronic module.
IMPORTANT: The document may refer to optional
components and certain functions, options, or accessories
may not be available for the specific unit. Heating option
applies only to heat pumps and cooling-only units
equipped with a boiler.
2.2 System functionalities
The system controls the start-up of the compressors needed to
maintain the desired heat exchanger entering and leaving water
temperature. It constantly manages the operation of the fans in
order to maintain the correct refrigerant pressure in each circuit
and monitors safety devices that protect the unit against failure
and guarantee its optimal functioning.
2.3 Operating modes
The control may operate in three independent modes:
●Local mode: The unit is controlled by commands from the
user interface.
●Remote mode: The unit is controlled by dry contacts.
●Network mode: The unit is controlled by networks (Proprietary
Protocol). Data communication cable is used to connect the
unit to the proprietary protocol communication bus.
When the control operates autonomously (Local or Remote),
it retains all of its control capabilities but does not offer any
features of the Network.
CAUTION
Emergency stop! The Network emergency stop command
stops the unit regardless of its active operating type.
2.4 CONNECT TOUCH control system
●Allows users to control the unit via the CONNECT TOUCH
user interface.
●Provides web connectivity technology.
●Includes the trending functionality.
●Supports Enhanced Control Management (Connected
Services, Cristo Control, Power Control, Easy/Smart Control)
for multiple chillers/heat pump configuration.
●Provides direct BMS integration capabilities (Modbus RTU,
Modbus TCP/IP, BACnet/IP option or Lon option).

3 - CONTROL COMPONENTS
EN-7 AQUACIATPOWER

4.1 Control boards
The electrical box includes all boards controlling the unit as well
as the CONNECT TOUCH user interface.
Each circuit is by default fitted with one SIOB board used to
manage all major inputs and outputs of the controller.
Options such as energy management module or free cooling
(dry cooler management) require the installation of additional
boards, i.e. EMM SIOB board for energy management module
and FC dry cooler board for free cooling. Additionally, units with
seven or eight fixed speed fans are fitted with an additional
auxiliary 2 board “AUX2 board”.
All boards communicate via an internal bus.
4.2 Power supply to boards
All boards are supplied from a common 24 VAC supply referred
to earth.
CAUTION
Maintain correct polarity (and grounded 0V) when
connecting the power supply to the boards, otherwise
the boards may be damaged.
In the event of a power supply interrupt, the unit restarts
automatically without the need for an external command. However,
any faults active when the supply is interrupted are saved and may
in certain cases prevent a given circuit or the unit from restarting.
The main board continuously monitors the information received
from various pressure and temperature probes and accordingly
starts the program that controls the unit.
The number of boards available in the electrical box depends on
the number of selected options.
4.3 Light Emitting Diodes on boards
All boards continuously check and indicate the proper operation
of their electronic circuits. A light emitting diode (LED) lights on
each board when it is operating properly.
●The red LED flashing for a two-second period indicates
correct operation. A different rate indicates a board or a
software failure.
●The green LED flashes continuously on all boards to show
that the board is communicating correctly over its internal
bus. If the green LED is not flashing, this indicates the
internal bus wiring problem or a configuration issue.
4.4 Pressure transducers
Three types of transducers (high pressure, low pressure, water
pressure) are used to measure various pressures in each circuit.
These transducers deliver 0 to 5 VDC. They are connected to
SIOB boards (circuit A and circuit B).
Discharge pressure transducers (high pressure type)
These transducers measure the discharge pressure in each
circuit. They are used to control condensing pressure or high
pressure load shedding. Discharge pressure sensors are
mounted on the discharge line piping of each circuit.
Suction pressure transducers (low pressure type)
These transducers measure the suc t ion pressure in each circuit.
They are used to control EXV, evaporating pressure (in heating
mode) and monitor suction pressure safeties related to the
compressor operating envelope. Suction pressure sensors are
located on the common suction piping of each circuit.
Pump inlet/outlet water pressure transducers (water
pressure type, hydronic kit option)
These transducers measure the hydronic kit pump inlet/outlet
water pressure and monitor the water flow. Pump inlet/outlet
water pressure sensors are mounted on the optional hydronic kit.
4.5 Temperature sensors
Temperature sensors constantly measure the temperature of
various components of the unit, ensuring the correct operation
of the system.
Water heat exchanger entering and leaving water
temperature sensors
The water heat exchanger entering and leaving water temperature
sensors are used for capacity control and safety purposes.
Outdoor air temperature sensor
This sensor measuring the outdoor air temperature is used for
start-up, setpoint temperature reset and frost control.
Suction gas temperature sensors
These sensors measure the suction gas temperature. They are
used for the EXV control. Suction gas temperature sensors are
located at the suction side of each circuit.
Master/slave water sensor (optional)
This sensor measures the common water temperature in the
master/slave system capacity control. It is installed only in the
case of master/slave units.
Defrost temperature sensors (heat pumps)
These sensors are used to determine the end of the defrost
cycle for a given circuit.
Temperature setpoint reset sensor (Energy Management
Module)
This sensor measures the space (room) temperature for the
purpose of setpoint reset.
4.6 Actuators
Electronic expansion valve
The electronic expansion valve (EXV) is used to adjust the
refrigerant flow to changes in the operating conditions of the
machine. The high degree of accuracy with which the piston is
positioned provides precise control of the refrigerant flow and
suction superheat.
Water flow switch
For units without internal pumps, a flow switch is mounted
to ensure that the minimum flow rate required for the correct
operation and protection of the system is maintained.
The minimum flow rate threshold depends on the unit size and
is configured automatically at the start-up. If the flow switch
fails, the alarm condition shuts off the unit.
Water heat exchanger pumps (optional)
The controller can regulate one or two fixed speed or variable
speed water heat exchanger pumps and takes care of the
automatic changeover between these pumps.
Four-way valve (heat pumps)
The control actuates the four-way valve for cooling / heating
mode and defrosts' sessions.

EN-9 AQUACIATPOWER

4.8 RS485 wiring (best practice)
For RS485 ports, one of the following cables can be used:
■two twisted pairs + a shield (RECOMMENDED)
■three wires + a shield
Note that “+” and “-” are communication signals and they are
from the same twisted pair.
The signal ground could be a single wire or a twisted pair and it
should be connected to the “C” pin of J10 (Modbus RTU) or J7
(Proprietary Protocol). This wire is required so that all nodes on
the bus share a common ground reference connection.
If a shield is used, then the shield cable should be properly
terminated and connected as short as possible at ONLY one
end to the chassis ground (4.3-inch controllers).
4.8.1 RS485 wiring: 4.3-inch controller
The following diagrams illustrate possible RS485 wiring
schemes for 4.3-inch controllers.
The first wiring scheme is the best option (RECOMMENDED),
but the second or the third wiring can also be used.

C Keep shield continued
D Connect shield to earth ground only at one point
End of Line Resistor: Termination is only needed when running
at bus at very high speed over long distances.
The speed of the bus and the cable distance determine
whether termination is needed. It is meant to balance the bus
to minimize the ringing that may be caused by fast signals and
the inductance of the cabling.
At 9600 baud, termination will have little or no effect on the bus.

5.5 Set the schedule
The control incorporates two time schedules, where the first one
(OCCPC01S) is used for controlling the unit start/stop, whereas
the second one (OCCPC02S) is used for controlling the dual
setpoint (Setpoint 1 used in Occupied mode / Setpoint 2 used
in Unoccupied mode).
The control offers the user the possibility of setting eight
occupancy periods where each occupancy period includes the
following elements to be defined:
Day of the week: Select the days when the period is
occupied.
Occupancy time ("occupied from" to "occupied to"): Set
occupancy hours for the selected days.
Timed Override Extension: Extend the schedule if necessary.
This parameter can be used in the case of some unplanned
events. Example: If the unit is normally scheduled to run
between 8:00 to 18:00, but one day you want the air-
conditioning system to operate longer, then set this timed
override extension. If you set the parameter to "2", then the
occupancy will end at 20:00.
NOTE: Time override extension is available only with the
optional Energy Management Module.
To set the unit start/stop schedule
1. Go to the Main menu.
2. Navigate to the Configuration menu (logged-in users only)
and select Schedule Menu (SCHEDULE).
3. Go to OCCPC01S.
4. Select appropriate check boxes to set the unit occupancy
on specific days.
5. Define the time of occupancy.
6. When the time schedule is set, the selected period will be
presented in the form of the green band on the timeline.
