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 :
