Use
The latest generation of DYNACIAT water chillers and heat
pumps are the perfect solution for all cooling and heating
applications in the Offices, Healthcare, Industry, Administration,
Shopping Centres and Collective Housing markets.
For quick and easy installation, a range of hydronic modules
is available as an option on the evaporator side (for chilled
water production) and the condenser side (for hot water
production).
These units are designed to be installed in machine rooms
that are protected against freezing temperatures and
inclement weather.
DYNACIAT is optimised to use ozone-friendly HFC R410A
refrigerant.
When producing chilled water, these units can be connected
to a drycooler or a water cooling tower. This range is also
available in a "split system" version without a condenser
(LGN series).
This range guarantees compliance with the most demanding
requirements for increased seasonal energy efficiency
(ESEER and SCOP) and CO2 reduction to comply with the
various applicable European directives and regulations.
Connected to an underfloor heating-cooling system, comfort
units or an air handling unit, DYNACIAT can heat or cool
buildings by reversing the cycle on hydraulic circuits using a
set of valves (hydraulic valves not supplied).

■ Remote management
Connect Touch is equipped as standard with an RS485 port
and an ETHERNET (IP) connection, offering a range of options
for remote management, monitoring and diagnostics.
Using the integrated Webserver, a simple internet connection
uses the unit's IP address to access the Connect Touch
interface on the PC, facilitating everyday management tasks
and maintenance operations.
A range of communication protocols are available: MODBUS/
JBUS RTU (RS485) or TC/IP as standard, LONWORKS –
BACNET IP as an option, enabling most CMS/BMS to be
integrated.
Several contacts are available as standard, enabling the
machine to be controlled remotely by wired link:
-
Automatic operation control: when this contact is open, the
machine stops
- Heating/cooling operating mode selection
-
Setpoint 1/setpoint 2 selection: when this contact is closed,
a second cooling setpoint is activated (energy storage or
unoccupied mode, for example)
-
Power limitation: closing the contact allows the power and
refrigerating consumption of the machine to be limited by
stopping one or more compressors (this limit can be set with a
parameter)
- Fault reporting: this contact indicates the presence of a major
fault which has caused one or both cooling circuits to stop
- Operational status reporting indicates that the unit is in production
mode.
- Switch control for the customer pump, external to the machine
(on/off).
Contacts available as an option:
- Setpoint adjustable by 4-20 mA signal: this input allows the
setpoint to be adjusted in COOLING mode.

■ Maintenance
Connect Touch has two maintenance reminder functions as
standard, making users aware of the need to regularly perform
maintenance operations and to guarantee the service life and
performance of the unit. These two functions can be activated
independently.
A reminder message appears on the unit's HMI screen, and
stays there until it is acknowledged by the maintenance
operator. The information and alert relating to these functions
are available on the communication bus to be used on the
CMS/BMS.

- t
he scheduled maintenance reminder: when activated,
this function enables the period between two maintenance
inspections to be set. This period may be set by the operator
in either days, months or operating hours, depending on the
application.
- the compulsory F-GAS sealing test maintenance reminder:
when activated, this function, which is the default factory
setting, enables the period between two sealing tests to
be selected, according to the unit's refrigerant charge, in
compliance with the F-GAS regulations

(4)On delivery, the vessels are preinflated to a standard value, which may not be the optimum one for the installation. To enable the water volume to be varied as desired,
adapt the inflation pressure to a value close to that which corresponds to the static height of the installation. Fill the installation with water (bleeding out any air) at a
pressure more than 10 to 20 kPa higher than the vessel pressure.
