The Aqu@net electronic control system has been specifically
designed for wall mounted, ceiling mounted or cassette type fan
coil units, all with full air recycling, for the following applications :
2 pipe cooling only, 2 pipe heating only, 2 pipe / 2 wire,
2 pipe reversible with or without additional electrical heating
and 4 pipe installations.
The system comprises an FCC controller integrated in the fan coil
unit and an RCL control, capable of being fitted as an option to our
entire range of low wall mounted fan coil units.
Aqu@net is a new generation of communicating electronic control
via a proprietary bus using an easily installed additional PCB and a
monitoring module known as µBMS (refer to the manual relating
to this monitoring module).
Furthermore, in the case of small installations, this control system
enables a master / slave network to be created very easily by
means of hardwired connections, and it enables up to 15 units to be
controlled with a single RCL control.
The Aqu@net electronic control system has been designed to
achieve an optimised compromise between running costs (heating
valve for integral proportional control), ergonomics and
performance.
It is compatible with the µBMS monitoring module and
communicates via a proprietary bus, as well as being capable of
operating without a monitoring module.
The Aqu@net electronic control system can be adapted to the
following air conditioning system models :

In the event of a power cut, the RCL control can retain and
display operating mode, ventilation speed and set temperature
data for 10 minutes.
Beyond 10 minutes, the digital display is cleared and the data is
lost.
As soon as the power supply is re-established, the digital display
reactivates itself in the last operating mode selected, but the
data concerning the ambient temperature is always lost.
Press the ON/OFF key twice to reactivate the complete
system and recover the ambient temperature value.
By successive presses, this key enables the ventilation
speed to be selected :
- Low speed (2 bars)
- Medium speed (4 bars)
- High speed (6 bars)
- Automatic speed (6 bars + AUTO)
By successive presses, this key enables the displayed
temperature to be selected.
A pictogram representing a house appears when
the room temperature is displayed.
If the house is not present, then the desired room
temperature is being displayed.
TEMP These keys enable the desired temperature in the
room to be raised or lowered (set temperature).
By successive presses, this key enables the fan coil
units to be started or moved into standby mode. The
standby/off status is indicated by a green LED.
GREEN LED On : Fan coil unit running.
Off : Fan coil unit stopped.
Slow flashing : Unoccupied mode activated.
Rapid flashing: Condensate level alarm.
MODE By successive presses, this key enables the desired
operating mode to be selected (according to the
settings on the mode selection block - refer to page
3).
Ventilation only mode.
Cooling mode (Summer).
Heating mode (Winter).
Automatic operating mode selection (in Heating or
Cooling mode).
Sending data to the FCC controller or blocked
keypad signal.
The RCL control has been designed specifically for use with fan coil
units equipped with the Aqu@net system.
In no event can it be used with any other type of control
system.
It operates independently on units equipped with an FCC controller,
irrespective of the configuration (A, B, C, D, E).
When the electrical connections have been made correctly, the
digital display indicates the set temperature, the operating mode
and the ventilation speed.
NOTE : When the RCL control is mounted on a panelled unit, its
blue connector is not plugged into the FCC controller.

Window contact switch function :
The FCC controller has 2 terminals (5 and 6) marked WIN, intended
to be connected to an opening contact switch for activating the
window contact switch function (window closed = contact switch
closed).
The window contact switch function stops the fan coil unit (valve or
electrical resistance cut) and moves the unit into cyclical ventilation
mode with an anti-freezing heating temperature protection set at
8 °C.
IMPORTANT : In all cases, the electrical resistance post-ventilation
function is maintained.

3 - Electrical power supply and connection terminal blocks
On the Aqu@Net system, the FCC controller is supplied directly
with 230 V / 1 phase / 50 Hz current and pilots the RCL control
under very low voltage.
It comprises 6 terminal blocks as described below :
1- The first terminal block, known as the power supply block enables
230 V supply to be provided to the system. Each terminal is
marked on the plastic cover with L for the phase, N for neutral
and the ground symbol for ground.
2- The second terminal block is used for connecting the fan coil
unit's constituent elements (fan, cooling mode valve, heating
mode valve, electrical resistances etc.). The terminals are
connected at the factory according to the requested application.
3- The third terminal block marked MIU is the location set aside
for an additional communication PCB.
4- The fourth terminal block is provided for connecting the RCL
control.
There are two connection possibilities for this component :
- The FCC is supplied with a ceiling type fan coil unit : In this
case the RCL control is supplied as a kit.
- The FCC is supplied with a low wall mounted type fan coil
unit : In this case the RCL control is mounted on a bracket on
the casing side opposite to the hydraulic connections side.
5- The fifth terminal block comprises 3 connectors marked as
follows on the plastic cover:
- WPT : Water temperature probe.
It is only fitted to B and D type systems. It enables mode changing
in relation to water temperature that is measured via a probe
on the pipe work. For this reason, special care must be taken
when assembling this probe.
This probe must be fitted with a 4 way valve and upstream
of the valve on the water inlet (refer to diagram below).
We recommend that the probe is fitted with an electrician's
type collar, using contact paste and thermal insulation on the
pipe work.
- RAT : Intake air temperature probe.
The intake air temperature probe enables the fan coil unit to
be controlled by the air temperature reigning around the unit.
The major advantage of this system is that several units can be
controlled with a single RCL control.
This probe is connected at the factory in all cases and is installed
on the fan air intake.
- ALARM : Condensates upper level alarm probe.
In the case of fan coil units, this connector is systematically
supplied with a shunt and it not used.
In the case of chilled water cassettes, this contact switch is
connected to the condensates tray upper level contact switch.
This switch's function is to shut down the cassette (ventilation
and valve). Its operation is visualised by a rapid flashing of the
LED on the RCL control.
6- The sixth terminal block has 4 terminals marked in pairs on the
plastic cover as follows :
- WIN : Window contact switch (contact switch closed = window
closed). For this reason, this contact is always supplied with a
shunt.
- UNOC : Enables the room unoccupied / occupied function to
be activated via a dry contact switch (contact switch closed =
unoccupied mode). For this reason this contact switch is always
left free of potential.
