FWECSA
Controller for units
GENERAL FEATURES
The FWECSA controller is designed to control all of
the system units in the Daikin range with multi-speed,
single-phase motor or coupled to an inverter for speed
modulation.
The FWECSA controller system is composed of:
• I/O board containing the power supply circuit,
the microprocessor system and the connectors
(unscrewable) to connect the input and output devices;
• User unit composed of graphic display and keyboard
(six keys) equipped with clock and probe to read the
room temperature.
The connection between the I/O board and the
user unit is set up using the relative connectors
and a data transmission cable fitted with a pair
of twisted conductors and shielding.
The controller makes serial communication possible on two
types of networks:
• External Supervisor System solution: connection
to an external supervision system with MODBUS RTU
protocol on serial RS485;
• SMALL solution: connection of multiple FWECSA
controllers in two possible configurations:
- MASTER/SLAVE on serial RS485
- MASTER/SLAVE on CW (Conveyed Waves),
which can also be set up with External Supervisor
System solutions.
• Mixed net solution: connection of multiple FWECSA
controllers on different levels :
- MASTER/SLAVE on serial RS485 (external
supervisor system or FWECSA),directions to the
slaves RS485 (called zone MASTER)
- zone MASTER FWECSA , receiving directions from
NET MASTER RS485,transmitting directions to
SLAVES OC
- NET SLAVES OC, working exactly to the ZONE
MASTER
MAIN FUNCTIONS
• Automatic or manual fan speed variation (selected
from the keyboard);
• Management of ON/OFF or modulating valves for two
or four-piped systems.
• SUPPORTING electric heater control, used during
heating;
• SUMMER/WINTER mode switch (= cooling/heating)
in four possible ways:
- manually, from the keyboard;
- manually, remotely (from digital input);
- automatically, depending on water temperature;
- automatically, depending on air temperature.
• dehumidification function control;
• operation with TIME SLOTS.
It is also supplied with:
• External pre-consensus digital input (for example:
window contact, remote ON/OFF, presence sensor, etc.)
that can enable or disable unit operation (contact logic:
see board configuration parameters);
• Digital switching input Remote centralised Cooling/
Heating (contact logic: see board configuration
parameters);
• Digital input to enable ECONOMY function from
remote control (contact logic: see board configuration
parameters);
• Water temperature probe (accessory), one or two
(optional with 4-pipe systems);
• STANDARD room air temperature probe (installed
inside the user unit);
• Remote room air probe (accessory) that can be used,
if connected, in place of the standard one installed in
the user interface;
• Remote relative room air humidity probe (accessory);
• A completely configurable digital output (dry contact).
