1 - SAFETY CONSIDERATIONS
1.1 - Safety guidelines
Installation, start-up and servicing of equipment can be
hazardous if certain factors particular to the installation are
not considered: operating pressures, presence of electrical
components and voltages and the installation site (elevated
plinths and built-up structures).
Only properly qualied installation engineers and highly
qualied installers and technicians, fully trained for the
product, are authorised to install and start-up the equipment
safely.
During all servicing operations all instructions and
recommendations which appear in the installation and
service instructions for the product, as well as on tags and
labels fixed to the equipment and components and
accompanying parts supplied separately, must be read,
understood and followed.
Failure to comply with the instructions provided by the
manufacturer may result in injury or product damage.
• Apply all standard safety codes and practices.
• Wear safety glasses and gloves.
• Use the proper tools to move heavy objects.
• Move units carefully and set them down gently.
1.2 - Safety precautions
Only personnel qualied in accordance with IEC (International
Electrotechnical Commission) recommendations may be
permitted access to electrical components.
It is particularly recommended that all sources of electricity
to the unit be shut off before any work is begun. Shut off the
main power supply at the main circuit breaker or isolator.
IMPORTANT: This equipment conforms to all applicable
codes regarding electromagnetic compatibility.
RISK OF ELECTROCUTION! Even when the main circuit
breaker or isolator is switched off, specic circuits may still
be energised as they may be connected to a separate power
source.
RISK OF BURNS! Electrical currents may cause
components to get hot. Handle the power cable, electrical
cables and conduits, terminal box covers and motor frames
with great care.
2 - CONTROL OVERVIEW
2.1 - System functionalities
The Touch Pilot system controls the start-up of the
compressors needed to maintain the desired heat exchanger
entering and leaving water temperature.
The control panel serves as a user interface and a conguration
tool for controlling the operation of the unit. Touch Pilot
constantly monitors safety devices that protect the unit against
failure and guarantee its optimal functioning.
2.2 - Touch Pilot components
The controller manages a number of mechanisms that allow
the unit to operate effectively, including the following:
• Compressor start-up to control the water loop
(screw compressor technology)
• 7’’ touch screen as standard (Touch Pilot)
• BMS connection
• Diagnostics, e-mail transmission
• Web connectivity
• Energy Management Module (optional)
• Hydronic module, variable-speed pump control (optional)
• External xed-speed or variable-speed pump control
• Remote unit management
• Energy optimization, power/energy monitoring
• Maintenance schedule management
• Communication protocols (CCN, BACnet, Jbus, LON)
2.3 - Operating modes
The control system can 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 network
commands (CCN or BACnet). Data communication
cable is used to connect the unit to the RS485
communication bus or IP connection.
When the control operates autonomously (Local or Remote),
it retains all of its control capabilities but does not offer any
features of the Network.
IMPORTANT: Emergency stop!
The Network emergency stop command stops the unit
regardless of its active operating type.

3 - HARDWARE DESCRIPTION
3.1 - Control boards
Each circuit is by default tted with one SIOB board used
to manage all inputs and outputs of the controller. At the
same time, Energy Management Module (EMM) requires
an additional SIOB board to be installed. The control also
includes up to four AUX1 boards used to control refrigerant
leak detection option, master/slave assembly control, and
internal or external pumps’ control.
All boards communicate via an internal LEN bus.
Touch Pilot continuously monitors the information received
from various pressure and temperature probes and
accordingly starts the program that controls the unit.
The unit is equipped with the Touch Pilot user interface
(7- inch colour LCD touch screen).
The electrical box includes all boards controlling the unit
and the user interface.
3.2 - Power supply to boards
All boards are supplied from a common 24 VAC supply
referred to earth.
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 the unit from
restarting.
CAUTION: Maintain correct polarity when connecting the
power supply to the boards, otherwise the boards may be
damaged.
3.3 - 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 ashing for a two-second period on the
SIOB board indicates correct operation. A different
rate indicates a board or a software failure.
• The green LED ashes continuously on all boards to
show that the board is communicating correctly over its
internal bus. If the green LED is not ashing, this
indicates a LEN bus wiring problem.
3.4 - Connections of the main controller
Connections are located on the bottom side of the main
controller.
The controller comes with two RS485 ports, where the rst
port is used to connect to CCN (Carrier Comfort Network)
and the second RS485 port is used for internal communication
(LEN).The Ethernet port allows forTCP/IP communication
or BMS (Building Management System) connection thanks
to BACnet/IP communication.

2. Ethernet connector
3. CCN connector (RS485)
4. LEN internal bus (RS485)
5. Power supply connector (24 VAC)
3.5 - Pressure transducers
Two types of electronic sensors (high and low pressure) are
used to measure various pressures in each circuit.
These electronic sensors deliver 0 to 5 VDC. The sensors
are connected to the slave boards.
Suction pressure sensors (low pressure type)
These sensors measure the suction pressure in each circuit.
They are used for EXV control. Suction pressure sensors are
located on the suction piping of each circuit.
Discharge pressure sensors (high pressure type)
These sensors measure the discharge pressure in each circuit.
They are used to control head pressure or high pressure load
shedding. Discharge pressure sensors are mounted on the
discharge line piping of each circuit.
Oil pressure sensors (high pressure type)
These sensors measure the oil pressure of each compressor.
Oil pressure sensors are located at the oil port of the
compressor.The economizer pressure is subtracted from this
value to arrive at the differential oil pressure.
Economizer pressure sensors (high pressure type)
These sensors measure the intermediate pressure between
discharge and suction pressure. They are used to control the
economizer performance.

3.6 - Temperature sensors
Temperature sensors constantly measure the temperature of
various components of the unit, ensuring the correct
operation of the system.
Evaporator entering and leaving water temperature sensors
The evaporator entering and leaving water temperature
sensors are installed in the entering and leaving side water
box.They are used for capacity control and safety purposes.
Suction gas temperature sensor
This sensor is used to control the suction gas temperature.
It is located at the suction line of the compressor.
Discharge gas temperature sensor
This sensor is used to control the discharge gas temperature,
and permits control of the discharge superheat temperature.
It is located at the discharge line of the compressor.
Motor temperature sensor
This sensor is used to control the motor temperature of each
compressor.
Temperature setpoint reset sensor (EMM)
This 4-20 mA space temperature sensor can be installed
remotely from the unit. It is used to reset the setpoint on the
unit.
Master/slave water sensor (optional)
The water temperature sensor is used for master/slave
assembly control.
Outdoor air temperature
The outdoor air temperature sensor is used for fan control.
3.7 - Actuators
Evaporator pumps
The controller can regulate one or two evaporator pumps
and takes care of the automatic changeover between these
pumps.
Electronic Expansion Valve
The electronic expansion valve (EXV) is used to adjust the
refrigerant ow to changes in the operating conditions of the
machine. To adjust the refrigerant flow, a piston moves
constantly up or down to vary the cross-section of the
refrigerant path. This piston is driven by an electronically
controlled linear stepper motor.The high degree of accuracy
with which the piston is positioned provides precise control
of the refrigerant ow.
Water ow switch
The water flow switch allows the control to ensure the
minimum water flow that is necessary for the proper
functioning of the unit. The conguration of its setpoint
depends on the unit size and is made automatically at the
start-up. If the measured water ow rate in the water loop is
lower than the congured ow rate, the alarm condition shuts
off the unit.

5.10 - Schedule setting
The control incorporates two time schedules, where the rst
one (OCCPC01S) is used for controlling the unit start/stop,
whereas the second one (OCCPC02S) is used for controlling
the dual setpoint.
• The rst timer program (schedule 1, OCCPC01S)
provides a means to automatically switch the unit from
an occupied mode to an unoccupied mode. The unit is
started during occupied periods.
• The second timer program (schedule 2, OCCPC02S)
provides a means to automatically switch the active
setpoint from an occupied setpoint to an unoccupied
setpoint. Cooling setpoint 1 is used during occupied
periods and cooling setpoint 2 during unoccupied periods.
Occupancy periods
The control offers the user the possibility of setting eight
occupancy periods where each occupancy period includes
the following elements to be dened:
• 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.
To set the unit start/stop schedule
1. Go to the Main menu.
2. Navigate to the Conguration menu (logged-in users only)
and select Schedule (SCHEDULE).
3. Go to OCCPC01S.
4. Select appropriate check boxes to set the unit occupancy
on specic days.
5. Dene 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.
7. Press the Save button to save your changes or the Cancel
button to exit the screen without making modications.
1. Selection of days for the time schedule
2. Start/end of the schedule
3. Save
4. Cancel
5. Previous time period
6. Next time period
Each program is in unoccupied mode unless a schedule time
period is active.
If two periods overlap and are both active on the same day,
then the occupied mode takes priority over the unoccupied
period.
Example: Schedule setting (schedule 1)

Holidays
The control allows the user to dene 16 holiday periods,
where each period is dened by three parameters; the month,
the start day and the duration of the holiday period.
During the holiday periods, the controller will be in occupied
or unoccupied mode, depending on the periods validated as
holidays. Each holiday period can be modied by the user via
the Conguration menu.
