Automatic cool/heat changeover based on water temperature.

Automatic cool/heat changeover based on air temperature.

Control of the 3-way/4-port ON/OFF valve. The water valve shut-off once the desiredtemperature is reached.

The controller controls the electric heater as integration or replacement of the hot waterheating system. When the operating mode selector witch is turned on “electric heater” and theelectric heater is turned on, the fan runs continuously at medium speed.

The fan speed can be set at one of the 3 speeds (low, medium or maximun) by turning theoperation mode selector.

The fan speed is switched automatically based on the difference between the temperature seton the thermostat and the room temperature.

Optimised comfort cooling. When the fan coil has reached the desired setpoint, the fan willoperate at medium speed and at regular intervals to ensure constant room temperature andlower sound.

The controller prevents the fan coil unit from operating in one mode, if the required watertemperature is not achieved to operate in the selected mode.

The dead zone is a temperature interval close to the set temperature. When the air is warmer/cooler than the top/lower limit of the neutral zone, the cooling/ heating mode is selected.

Daikin fan coil units deliver quiet, reliable, controllablecomfort of air conditioning without all the noise of othercentral systems.

Fan coil units are a highly efficient means of turning awater chiller or hot water boiler into an efficient, quietair conditioning system.

The units are super quiet because the only moving part isthe fan; making them ideal for use in offices, hotels andthe home.

The new range of fan coil units offers 5 models, of which3 in flexible application. A wide range of accessories isavailable.

For the ultimate in quiet, controllable air conditioningwith all the comfort but none of the bulk or noise, theclear choice is Daikin.

FWV, FWL, FWMEasy to installFast and easy field set up, ready for use!

KEY HOLE SYSTEM / LEVELLING

• quick fixing system for wall/ceiling mountingadvantage : no need to unscrew the nut

• units just need to be perfectly leveledadvantage : no need to calculate the condensate drainage

WATER CONNECTION

• pre-assembled 3-way/4-port ON/OFF valves are available• valve packages are insulated, no extra drain pan required• valve packages contain balancing valves and sensor pocket• valve packages can be factory-mounted and are leak tested• same valve package can be installed vertically and horizontally, on the

right or on the left side of the unit without changeadvantage : easy to connect even when space is limited

CONDENSATE DRAINAGE

• condensate drain pan features slopes to reduce water accumulation• supplied with flexible rubber hose pipe for easy connection

advantage : eliminates the need to align drain pan outlet withcustomer pipingadvantage : no need for collar if pipe diameter is compatible

QUICK ELECTRICAL CONNECTIONS

• fast-on connections for electrical options : no tools needed• controls are already factory-wired and tested

advantage : control panel no longer needs to be opened(external customer connections)

• wiring diagram on the cover of the electrical box

FWV, FWL, FWMEasy to maintainLow maintenance and high effeciency

FAN MOTOR/CONTROL PANEL ACCESSIBILITY

• 4 screws to access to the fan motor• fan board is removable without bringing the unit down• motor is life-lubricated and has a life span of 40,000 hours• control panel removable by a single screw• can be unfolded for a better component access• removable grilles• easy access to control valves

QUICK REMOVAL OF WASHABLE FILTER

• no tools needed• same system on vertical and horizontal units

advantage : very fast filter removal

ELECTRIC HEATER RESETTING

• no relay up to 2kW capacityadvantage : even quieter operation

• manual reset easily accessible• equipped with two overheat cut-out thermostats

(manual & automatic reset)advantage : anticipates the upcoming standards

STRUCTURE

• modular concept• height of the units only 240mm for all the sizes• cooling coil and fan module is made of:

- galvanised sheet steel- internally insulated (with 3mm close-cell polyurethane)

• key-hole system for fast mounting• rubber anti-vibration damper to isolate the unit from supporting structure• straight duct connector is mounted to both suction and discharge side (width 30mm)• a template is available in the carton box for easy connection to the ceiling

HEAT EXCHANGER

• 3, 4 or 6 stage row cooling coil• standard left handed water connections + air-purge

(water connections can easily be turned)• drain pan can to collect the condensate from:

- heat exchanger- regulating valves

FAN MOTOR ASSEMBLY

• 1, 2 or 3 centrifugal fans with forward profile blades, dynamically andstatically balanced

• 7-speed electrical motors (with thermal protection on windings)• all 7 speeds pre-wired in the factory in the terminal block of the switch box• to reduce the requested installation space is the terminal block located on

the same side as the water connections

AIR FILTER

• located in the air inlet• removable from the bottom• made of acrylic fiber, filter class EU2



7

FWD

FAN MOTOR ASSEMBLY

• dual intake centrifugal fans made of aluminum, dynamically and statically balanced• 3-speed electric motor, installed on vibration damping supports

(with thermal protection on windings)

AIR FILTER

• air-intake module + Filter is standard delivered with each unit• removable filter from the bottom• made of acrylic fiber, filter class EU2

STRUCTURE

• possibility of installation both in horizontal and vertical position• reduced height 280mm up to model 10• the unit is made of:

- galvanised sheet steel- insulated with noise-proof/anti-condensing material(self-extinguishing in Class 1, with a thickness of 10mm)

• key-hole system for fast mounting• straight duct connector is mounted to discharge side

(width 30mm)

HEAT EXCHANGER

• 1 or 2 stage row cooling coil• standard left handed water connections + air-purge• system for collecting and discharging condensate setup either for ceiling or wall

mounting

Easy to control !The new fan coil units can be operated by 3 differentcontrollers:• electronic control built-in (ECFWEB6)• electronic control remote (ECFWER6)• electromechanical control built-in (ECFWMB6)

The electronic control consists of:• operating mode selector, to turn the fan coil on and off,

to choose the type of operating mode (automatic or atfixed speed) and to control the electric heating

• cooling / heating selector• operational LEDs that indicates the current operation mode• thermostat to control the room temperature• free contacts for external enabling signal that may switch

on or off the unit.• free contacts for centralized cool/heat changeover• water temperature probe• air temperature probe

Several configurations are possible by changing dip switches.

The electromechanical controller includes a fan speedselector (3 speeds + stop) and manual cool/heat changeover.In case of the on/off valves, control can also be donethrough this controller.

Power interface / master slave interfaceAn additional interface is required for units with acurrent greater than 1,12A.Master slave interface (EPIMSA6: 4x3A)For remote control of up to 4 fan coil units, an optionalmaster/slave interface can be installed. Up to 3 EPIMSA6can be connected in parallel (--> max. 12 fan coils).Power interface (EPIA6: 1x16A)This is absolutely required for connection of ECFWER6 toFWD12 to18. It can be used as an alternative for EPIMSA6for all other fan coils.

master slave interface is only needed in case of remote control ofmultiple fan coil units
