ILTC control system
- Condensing pressure control is included as standard, thus
enabling all Aqu@Logic units to operate between - 10 °C and
+ 46 °C. Condensing pressure control is provided by an
algorithm, automatically managing the fan speeds operation. In
partial load or low ambient outdoor temperature conditions, the
fan is switched automatically to low speed running, offering a
significant reduction in noise levels.
- As standard, the ILTC control system offers the possibility of
selecting a "Night-time running mode" function.
- Water pump control with 2 possible operating modes:
Continuous operation in ON / OFF mode or operating only in
ON mode.
When the “Night-time Running” mode is activated, four
operating modes are available :
1
st
mode : Selected to change the set temperature for energy
savings when the building is unoccupied.
2
nd
mode : Selected to enable the set temperature to be lowered.
3
rd
mode : Selected to change the set condensing pressure
values, to force the fan to run at low speed and to obtain silent
running during the night.
4
th
mode : Selected for applying a combination of modes 1 and 3.
- In addition, as a standard feature, the ILTC control system
offers the possibility of automatically compensating the set
temperature value in relation to changes in the outdoor air
temperature.
- Automatic switching of cooling or heating mode in relation to
the two thresholds of external temperature configurable by the
user.
Safety
The system measures changes in parameters (temperatures,
pressures,…) and reacts to keep the compressor within its
operating range.
If, despite everything, a parameter exceeds its limit, a warning
message is generated and the machine is shut down.
The following faults cause the machine to shut down :
- Suction pressure too low.
- Discharge pressure too high.
- Outlet water temperature below authorised limits.
- Discharge temperature too high.
- Compressor(s), fan(s), water pump overload.
- Compressor direction of rotation reversed.
- Temperature sensors and pressure transducers fault.
- Evaporator anti-freeze protection.
The ILTC control system has 33 alarm codes enabling the origin
of breakdowns to be determined.
The following safety devices protect the units :
- Water flow switch or differential pressostat.
- Fan high speed and low speed thermal relays.
- N° 1 and N° 2 compressor internal thermal protection.
- Hydraulic pump thermal relay.
- HP safety pressostat.
Remote unit management
The system enables the following functions to be operated, by
means of dry contacts :
- Remote ON / OFF switch.
- Remote Day / Night running mode switch.
- Loadshedding mode.
- Remote alarm reading.
- Inversion of cooling or heating operating mode.
The ILTC control system is an intelligent digital control system
designed especially for optimising the operation of Aqu@Logic
units and maintaining conditions of maximum comfort.
Before each start-up, the ILTC control system runs through a
complete machine checklist. It continuously monitors and manages
all the machine’s operating parameters and safety devices. It
precisely manages the running of the compressors and fans in
order to optimise energy consumption. It also controls the operation
of the water circulation pump.
User interface :
The ILTC control system has an easy-to-use user interface
comprising a 4 character, 7 segment red colour LED display, 3
keys below the display for access to the different menus : the right
key is reserved for the TEST mode, the centre key for scrolling up
and down the menus, and the left key for selecting a parameter
and displaying its value.
Six main menus are available for accessing all the machine’s
controls :
- Parameters.
- Temperature sensors and pressure transducers.
- Active safety alarms.
- Compressors’ operating times.
- Safety alarms history (last 10 alarms).
- Machine operating status.
Using these 6 menus enables a machine status diagnosis to be
performed as well as checking all the Aqu@Logic unit’s parameter
settings.
ILTC control system description
- Intelligent regulation with return water temperature control and
outlet water temperature measurement.
- The selection and operating time duration of each compressor
is automatically managed by the ILTC control system, with the
possibility of balancing the compressors’ operating times. When
they are operating, the compressors are monitored constantly
to improve their operating cycle and to avoid any excessive
cycling. Thus, these Aqu@Logic units can operate in complete
safety with a low volume of water in the installation, enabling
the buffer tank to be dispensed with in the majority of comfort
air conditioning applications.
- The ILTC control system is intelligent, i.e. it continuously adapts
to changes in the installation’s thermal load by optimising running
times with the selection of one or both compressors, in relation
to actual demand.
