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 qualified installation engineers and highly qualified
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 qualified 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, specific 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.
2.1 Control system
AQUACIAT
CALEO
units come with the Connect Touch control that
serves as a user interface and a configuration tool for controlling
the operation of the heat pump.
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
unit to maintain the correct refrigerant pressure in the circuit
and monitors safety devices that protect the unit against failure
and guarantee its optimal functioning.
Connect Touch controls:
• compressor start-up to control the water loop
•
fixed or variable-speed pumps to optimise water loop
operation
2.3 Connect Touch components
The controller manages a number of mechanisms that allow
the unit to operate effectively, including the following:
• 4.3’’ touch screen
•
BMS connection
•
Scroll compressor technology
• Diagnostics
• Web connectivity / e-mail transmission
• Heating control
•
Electric Heating Stages control
• Domestic Hot Water production (optional)
• Boiler control (optional)
2.4 Operating modes
Connect Touch control may operate in three independent modes:
•
Local:
The unit is controlled by commands from the user
interface.
•
Remote:
The unit is controlled by dry contacts.
•
Network:
The unit is controlled by network commands.
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 mode.
IMPORTANT: Emergency stop! The Network emergency
stop command stops the unit regardless of its active
operating type.
