FCW WALL-MOUNTED FAN COIL UNIT

The fan coil unit is a terminal unit for conditioning internal air both in winter and summer. The FCW fan coil unit for wall mounted installation concentrates high technological and functional charac- teristics that make it the ideal climate control unit for all environments. The supply of climate controlled air is immediate and distributed through- out the room; FCW generates heat if included in a heating system with a boiler or heat pump but may also be used in the summer as an air condi- tioner if the system has a water chiller. The fan coil unit is designed to ensure maximum compliance with safety regulations. Several versions of FCW fan coil units are available in order to satisfy all types of installations: - with internal 2-way-valve, - with internal 3-way-valve - without valve. Each version is available: - With microprocessor controller (requires the addition of the PFW2 wired control panel accessory or the TLW2 remote control accessory.) - Without microprocessor controller which then requires a cable connected accessory panel or connection to the accessories of the VFM system (the VMF-E0 and VMF- E1 thermostats cannot be installed internally to the fan coil unit). In particular, the possibility to be integrated into the VMF system allows the control of a single fan coil unit with accessories, up to the control of the fan coil unit installed in a complex network. By choosing the appropriate options it is possible to select the model to suit the specific system requirements: Unit configuration

The PFW2 makes it possible to set the main operating parameters of the unit. These parameters are shown on a liquid crystal display making pro- gramming operations easier. A PFW2 wired control panel can con- trol just one fan coil unit.31 English

IFCW3LJ 1210 - 5375700_01

• Versions without microprocessor controller: With or without water valve. Versions without microprocessor con- troller need to be combined with a control panel (accessory) chosen from standard control panels (compatible with the configuration of the fan coil unit) or be combined with a thermo- stat from the VMF system. Warning! The VMF (VMF-E0 / VMF-E1) thermostat can not be installed inside the fan coil unit but the installer must provide an adequate housing close to the fan coil unit (such as a recessed electrical box on the wall behind the fan). VMF (Variable Multi Flow System) Management and control system of hydronic systems for the air-condi- tioning, heating and production of domestic hot water. The VMF system allows complete control of every component of a hydronic system both locally and centrally and, communicating between the various components of the system, manages the performance without ever neglecting the end user's request of comfort, but reaching it as efficiently as possible with energy saving. If you add the advantages deriving from such an innovative control to the flexibility of a hydronic system, you get a more efficient and effective alternative to the variable refrigerant flow systems (VRF). The VMF system is extremely flexible, enough to allow various steps of con- trol and management, expandable at different moments:

1) Control of a single fan coil

2) Control of a microzone (one

MASTER fan coil unit and a maxi- mum of 5 SLAVE fan coils units).

3) Control of multi independent

zones system (one MASTER fan coil unit and a maximum of 5 SLAVE fa coil units for each zone).

4) Control of a fan coil unit sys-

tem, plus management of the heat pump (if compatible with the VMF system).

5) Control of a fan coil unit sys-

tem, heat pump and management of the domestic hot water system (VMF- ACS).

6) Control of a fan coil unit sys-

tem, heat pump, domestic hot water production and additional circulators (up to a maximum of 12 using three additional VMF-CRP modules).

7) Control of a fan coil unit system,

heat pump, domestic hot water pro- duction, additional circulators and management of heat recovery units, maximum 3, (with the ability to han- dle up to 3 VMF-VOC sensors) or a boiler.

• The VMF system can operate and manage, through a VMF-E5N / VMF- E5B panel, a maximum of 64 zones consisting of a MASTER fan coil unit and a maximum of 5 SLAVE fan coil units connected to each MASTER, for a total of 384 fan coil units.

• Besides the central control supplied by the VMF-E5N / VMF-E5B panel, the MASTER fan coil units must be provided with a local control inter- face; this interface can be mounted on the fan coil unit (only for the mod- els (where it is possible) or be mount- ed into a wall panel (VMF-E4 / VMF- E4D).

• Different functions can be controlled through the VMF-E5N / VMF-E5B panel, including: - Identify the different zones giving a name for each one. - Check and set the ON-OFF function and the set point temperature of each zone. - Set and manage the set point temper- ature of the heat pump. - Scheduling time clocks.

• Simple installation of the fan coil unit system through the SELF- MONITORING function of the MASTER fan coil units.

• Versions with microprocessor con- troller: With or without water valve. Versions with microprocessor control- ler have a display on the front panel showing the main functions of the unit. The versions with microprocessor con- troller need to be combined with one of the two available control systems (accessories PFW2 or TLW2) provided as required as a necessary accessory for the unit operation allowing turn- ing on, turning off and all the fan coil unit control and programming operations. The two control systems cannot be used at the same time on the same fan coil unit. The control system checks all the func- tioning parameters and carries out all the operations necessary to enable the required room conditions to be maintained. The control system also provides some automatic functions to increase com- fort and make the most frequently repeated operations easier: - Minimum temperature sensor; in order to avoid cold air blasts in the winter mode, allowing ventilation only if the water in the system is hot. - Auto Restart mode, after a power out- age the FCW unit starts again auto- matically with the same settings that it had at the time of stopping (with the exception of the Timer and Sleep settings). GENERAL INFORMATION32 English

IMPORTANT INFORMATION

WARNING: The fan coil unit is connected to the power

supply and a water circuit. Operations performed by per- sons without the required technical skills can lead to personal injury to the operator or damage to the unit and surrounding objects. MALFUNCTION In the case of a malfunction remove power to the unit then reapply it and start the unit again. If the problem occurs again, call your area After-Sales service department promptly. POWER THE FAN COIL UNIT ONLY WITH 230 VOLT, SIN- GLE PHASE, 50 Hz Use of other power supplies could cause permanent damage to the fan coil unit. USE THE (TLW2) REMOTE CONTROL OR THE WIRED CONTROL PANEL (PFW2) TO TURN THE FAN COIL UNIT

Do not turn the fan coil unit on or off using the auxiliary switch except in an emergency.

DO NOT PULL THE ELECTRICAL CABLE

It is very dangerous to pull, tread on or crush the electrical power cable or fix it with nails or drawing pins. A damaged power cable can cause short circuits and per- sonal injury. DO NOT PUT ANYTHING IN THE AIR OUTLETS Do not put anything at all in the air outlet slots. This could cause injury to people and damage to the fan. DO NOT USE THE FAN COIL UNIT IMPROPERLY Do not use the fan coil unit in animal husbandry applica- tions.

VENTILATING THE ROOM

Periodically air the room in which the fan coil unit has been installed; this is particularly important if the room is occupied by many people, or if gas appliances or sources of odours are present.

CORRECTLY CONTROLLING THE TEMPERATURE

The room temperature should be controlled in order to provide maximum comfort to the people in the room, especially if they are elderly, children or ill, avoiding sud- den changes in temperature between the outside and inside above 7 °C in summer. Careful choice of the room temperature will lead to energy savings.

CORRECTLY ADJUSTING THE AIR JET

The air coming out of the fan coil unit must not strike people directly; in fact, even if at a temperature that is higher than the room temperature, it could cause a cold sensation and resulting discomfort. Only adjust the vertical blades by hand. In the versions with microprocessor controller adjust the horizontal blade with the LOUVRE or SWING key of the remote control or the wired control panel. In the versions without microprocessor controller adjust the horizontal blades by hand. DURING OPERATION Always leave the filter in the fan coil unit during operation otherwise dust in the air will dirty the surfaces of the coil.

During cooling, water vapour may be present in the air dis- charge. During heating it might be possible to hear a slight hiss around the fan coil unit. Sometimes the fan coil unit might give off unpleasant smells due to the accumulation of sub- stances from the air of the room (especially if the room is not ventilated regularly. Clean the filter more often). During operation, there could be noises and creaks inside the device, due to the thermal expansion of the various components (plastic and metallic), but this does not indicate a malfunction and does not cause damage to the unit unless the maximum input water temperature is exceeded.

MINIMUM AVERAGE WATER TEMPERATURE

Dry bulb temperature of the air in the room °C

Wet bulb temperature

of the air in the room °C

Maximum inlet water temperature ............................ 70 °C Maximum operating pressure ................................... 13 bar Minimum average water temperature To prevent the formation of condensation on the exterior of the unit while the fan coil unit is operating, the average water temperature should not drop beneath the limits shown in the table below, determined by the ambient conditions. These limits refer to unit operation with fan at minimum speed. Flow rate limits: MODEL FCW 21 31 41 Minimum flow rate [l/h] 100 100 150 Maximum flow rate [l/h] 750 750 1100 OPERATIONAL LIMITS The installation site must be chosen in such a way that the maximum and minimum room temperature limits, Ta, are respected: 0°C < Ta < 40°C ; R.H. < 85%. Connect to a 230 V ~ 50 Hz power supply and earth connection, and ensure it remains within the limit of ±10% with respect to the nominal value.33 English

WARNING: before carrying out any

work ensure the individual has the appropriate personal protection.

WARNING: check that the power sup-

ply is disconnected before performing operations on the unit.

WARNING: wiring connections,

installation of the fan coil unit and rel- evant accessories should be performed by a technician who has the necessary technical and professional expertise to install, modify, extend and maintain systems and who is able to check the system for the purposes of safety and correct operation. In the specific case of electrical connections, the following must be checked: - Measurement of the electrical system insulation resistance. - Continuity test of the protective wir- ing. If the fan coil unit operates continu- ously in cooling mode in a room with high relative humidity, condensate might form on the air discharge. This condensate might be deposited on the floor and on any objects underneath. To prevent the formation of condensa- tion on the exterior of the unit while the fan is operating, the average water temperature should not drop below the operating limits shown in the manual determined by the room temperature and humidity conditions. These limits refer to unit operation with fan at mini- mum speed. In order to avoid air stratification and therefore achieve better mixing it is advised not supply the fan coil unit with water hotter than 65°C. The use of very hot water could cause creak-

Supply the system with flat faced con- nections. Make the hydraulic connections using the appropriate washers. ing due to the thermal expansion of the different components (plastics and metals). This does not cause damage to the unit if the maximum operating temperature is not exceeded. Instructions essential for the prop- er installation of the equipment are shown here. The final touches to all the operations are however left to the experience of the installation engineer in accordance with the specific needs. The FCW fan coil unit must be installed in such a position that the air can be distributed throughout the room and that there are no obstacles (curtains or objects) to the passage of the air from the intake. The unit must be arranged in such a way as to make ordinary maintenance easy (filter cleaning) and special maintenance, as well as the access to the air vent valve on the heat exchanger coil at a height of 190 to 220 cm. Hydraulic connections: Female diam. 1/2”G with flat faced flare connections. The direction of the water flow is indicated on the pipes of the unit. Condensate drain connections: FCW 21 - 31 and 41: Female with internal diameter of Øi 16 mm. The supply and return pipes must be equally sized, made of copper with a minimum diameter of 1/2", suitably insulated to avoid heat dispersion and dripping during cooling operation. The water and condensate drainage pipes and the electrical circuit wiring on the wall must be installed before- hand. The diameter of the hole for the connections must be at least 70 mm and the piping positioned in such a way as to maintain an adequate incli- nation along the entire route (min.1%), to ensure evacuation of the condensate produced in the cooling operation of the fan coil unit. The condensate drainage system must be correctly sized. To avoid unpleasant smells a trap is recommended if the condensate is connected to the sewage system. The service hole for the piping can be located on the right or left of the unit. The support wall must be sturdy and not subject to vibrations. Do not install the unit near sources of heat, vapour or flammable gas. Do not install in a position exposed to direct sunlight. Installation To install the unit, proceed as follows: - Put the template on the wall, fixing it solidly with at least six or more screws or expansion blocks of a type that is adequate for the thickness of the fixing wall, through holes near the edge of the template. The template must be fixed flush to the wall, perpendicular to the floor and perfectly level. Failure to respect these conditions will cause water to drip out of the drain tray. - Remove the cabinet. - The FCW unit permits 4 connection possibilities. For connections through the wall make a hole with a diameter of 70 mm, inclined downwards by 5-10 mm. For connections sideways and down- wards, remove the knock-outs of the cabinet in the direction of the pipes. - Carry out the electrical connections as shown on the wiring diagram. - If you intend to control the fan coil unit with the PFW2 wired control panel make the connection with the unit as indicated in the wiring dia- gram: remove the connector of the Infra Red receiver from the circuit board of the unit and connect the wired control panel to it . The cable is 4 metres long. - Make the water connections. If the pipe is repeatedly bent it may break. The unit's pipes indicate the direction of the water flow - Connect the condensate drain outlet to the drainage line and make sure it works properly. - Insulate the pipes properly. - Position the FCW unit on the tem- plate after passing the pipe through the hole or in the channelling in the wall. Check that the fan coil is level horizontally and vertically. - When all the installations have been

Coil air vent Screws Screw covers completed (electrical and hydraulic connections, fan coil unit fixing and condensate drain connection) close the hole in the wall with a suitable filler. - Vent the coil using the air valve pro- vided. - Complete the refitting of the com- ponents of the unit paying attention that the debris from the materials used for the installation do not block the fan or obstruct the filters or the grilles. - After installation perform a function- al test of the fan coil unit.45 English

WARNING: check that the power sup-

ply is disconnected before perform- ing operations on the unit. The unit must be connected directly to an electrical outlet or to an inde- pendent circuit. Provide a 230V (±10%) power supply. To protect the unit against short cir- cuits, fit a circuit breaker of max. 2A 250V to the power line with a minimum contact opening distance of 3 mm. The electrical power cable must be of the H07 V-K or N07 V-K type with 450/750V insulation rating if inside a tube or conduit. Use cables with double H5vv-F type insulation for exposed cable installation. Follow the wiring diagram supplied with the equipment and shown in this document when making the connec- tions. Ensure that the installation is wired in compliance with the laws and stand- ards in force, and with the instruc- tions in this manual. All the parts and materials supplied on site must comply with the local laws and regulations. WARNING The unit must be correctly earthed; incorrect con- nection could result in electric shocks or fires.46 English

INSTALLATION OF PFW2 WIRED

CONTROL PANEL (ACCESSORY) Accessory indispensable for the func- tioning of the fan coil unit. Alternative to the remote control TLW2. The two control systems cannot be used togeth- er. A PFW2 wired control panel can only control one fan coil unit. The panel can be fixed directly to the wall with two screws or a rectangu- lar electrical box. The panel cable is 4 metres long and is fitted with connector (B) for connection to the fan coil circuit board as shown in the wiring diagrams. To install the wired control panel it is necessary: - to disconnect the connector (A) of the infrared receiver from the circuit board inside the fan coil unit. - connect connector (B) of the wired control panel to the circuit board con- nector now vacant. The PFW2 makes it possible to set the operating parameters of the unit and these parameters are shown on a liquid crystal display, making programming operations easier. Avoid installing the panel in positions where it is directly exposed to the sun light.47 Français
