FWEC1
GENERAL CHARACTERISTICS
LCD controller has been designed to govern the operation
of Daikin indoor units with single-phase multispeed
asynchronous motor.
MAIN FUNCTIONS AND FEATURES:
■ Air temperature adjustment through automatic variation
of fan speed;
■ Regulation of air temperature via fan on-off control (fan
runs at a fi xed speed),
■ Control of On-Off valves for two or four-pipe systems
■ Control of heating element for auxiliary heating.
■ Cooling/heating switching in the following modes:
- local manual switching
- remote, manual (centralised);
- automatic, depending on water temperature
- automatic, depending on air temperature
Additional features include:
■ Digital input 1 – Clean contact for remote centralised
switching of cooling/heating function (contact logic: see
confi guration parameters of board).
■ Digital input 2 - Clean contacts for external activation (e.g.
window contact, remote ON/OFF, occupancy sensor, etc.)
which may enable or disable unit operation (contact logic:
see confi guration parameters of board)
■ Remote water temperature sensor (FWTSK)
■ Remote air sensor (FWTSK) (this sensor, if present, is used
in place of the internal one for the measurement of room
temperature).
The control panel is composed of:
■ LCD display
■ Keyboard

Operation mode: Cooling. When fl ashing it indicates
that water circuit is not enabled to fan ventilation.
Operation mode: Heating. When fl ashing it indicates
that water circuit is not enabled to fan ventilation.
Economy option enabled

Heating element. If the symbol fl ashes it means that
the heating element is on; if steadily lit it means only
that the heating element has been selected

KEYBOARD (SEE FIGURE 2)
On/Off key: Thermostat On/Off. During the
procedure of parameter modifi cation, it permits to
return to normal operating conditions
Up and Down keys: changing of thermostat
setting temperature (Heating :[5.0-30.0°C],
Cooling: [10.0-35.0°C]). During the procedure of
parameter modifi cation, they are used to select the
parameters or to change their value
SEL key: in the heating mode, the electric heating
element can be selected as auxiliary function
Mode key: selection of Heating/Cooling operating
mode
Fan key: selection of operating speed
EC key: selection of Economy mode
ACTIVE KEY COMBINATIONS
With OFF thermostat: access to the parameter confi guration
procedure
With ON thermostat: display of current water temperature
Selection of Minimum air temperature function
BOARD CONFIGURATION
The board can be confi gured according to the type of unit/
system to be governed by changing some parameters.
PARAMETER LIST
■ P00 = controller confi guration (see "Available confi gurations")
to select the type of unit to be governed.
■ P01 = type of controller installation
- 000: on the unit
- 001: wall mounted
■ P02 = (not used)
■ P03 = neutral zone [20-50°C/10]; parameter used in case of
confi gurations with automatic cooling/heating changeover
according to air temperature.
