CFF-ECM MV Carisma Whisper

Carisma Whisper | InTroducTIon

INTRODUCTION
The Carisma Whisper CFF-ECM fan coil unit combines a reduced dimension with a modern aesthetic, while maintaining great performances in terms of sound and consumption.
Carisma Whisper CFF-ECM includes the MV version for wall installation and the IV version for concealed installation; the MV version combines a reduced dimension, unti 126 mm depth only, with a modern aesthetic that perfectly suits with any kind of furnishing, while maintaining great performances in terms of sound and consumption.
The Carisma Whisper CFF-ECM range makes use of the excellent experience gained with the fan coil units with inverter board, first in the world in production since 2009, and which have had great success on all markets.
The latest synchronous inverter driven BLAC brush- less and sensorless electronic motor with permanent magnets is controlled by an Inverter board designed and developed in Italy. The electronic board is directly fitted on the motor. The air flow can be varied continuously with a 1-10 V signal. The continuous air flow control improves the acoustic comfort and allows a more punctual reply to the variation of the thermal loads and a greater stability of the requested ambient temperature. The extreme efficiency, also at a low speed, makes possible a great reduction in electric consumption with absorption values, under normal operating conditions, that are no greater than 5 Watt. The excellent values in terms of sound levels have been maintained in all working conditions, without any resonance phenomenon at any frequency.

 VERSION AND MAIN COMPONENTS

Range includes 5 air flow rates (from 75 to 645 m³/h) and 2 versions (standard with casing and for concealed installation), each one equipped with 2 row coil. The standard versions with the casing are available in the following combinations:

• without control (CFF-ECM-MV)
• with CB-E control (CFF-ECM-MV-CB-E)
• with CB-Touch control (CFF-ECM-MV-CB-T)

The CB-E and CB-Touch versions are supplied with their power units (UP-ECO and UP-Touch) fitted on the unit. The CB-E control must always be connected with a programmable thermostat (not supplied by us).
The Carisma Whisper CFF-ECM range is perfect to meet all air-conditioning requirements of residential and work environments like offices, shops, restaurants and hotel rooms.
Outer casing
Made of galvanized steel and with plastic outer casing
The air diffuser, that is placed over the top of the unit, is of adjustable type.
White RAL 9003.
Inner casing
Made of 1 mm galvanized steel, a rear panel and two lateral sides insulated with 3 mm polyolefin (PO) foam (class M1).
Filter
Polypropylene cellular fabric regenerating filter. The filter frame, made of synthetic material, is inserted into special plastic sliding guides fastened to the internal structure for easy insertion and removal of the filter.
Fan assembly
Made of plastic tangential fan with anti-vibration fins. The fan hub, dynamycally and statically balanced, is directly secured onto the motor shaft.
Electronic motor
Electronic motor with three phase permanent magnet brushless electronic motor that is controlled with reconstructed current according to a BLAC sinusoidal wave. The inverter board that controls the motor operation is powered by 230 Volt, single-phase and, with a switching system, it generates a three-phase frequency modulated, wave form power supply. The electric power supply required for the machine is therefore single-phase with voltage of 230 – 240 V and frequency of 50 – 60 Hz.
Coil
It is manufactured from drawn copper tube and the aluminium fins are mechanically bonded onto the tube by an expansion process. The coil has two Ø 1/2 inch BSP internal connections. The coil has Ø 1/8” inch BSP air vent and drain. The heat exchanger is not suitable for use in corrosive atmosphere or in environments where aluminium may be subject to corrosion. Flow and return pipe connections are situated at the same end on the left side looking at the unit. On request we can deliver the unit with the connections on the right end side: this must be specified on the order as this operation can not be carried out on site during installation.
Valves
The versions without valves or with mounted valves are available for all sizes. The available valves are:

• 2 way
• 3 way The valves can be ordered separately and easily installed on the basic units without valves.

Condensate collection tray
Made of plastic (ABS UL94 HB) and fixed to the internal structure. The outside diameter of the condensate discharge pipe is Ø 15 mm.

Controls

All the Carisma Whisper CFF-ECM units can be supplied and managed with the following controls:’

•  CB-E control fitted on the unit (only version with casing, available mounted on site or supplied with separate packaging)
• CB-Touch control fitted on the unit with Bluetooth and Wi-Fi features (only version with casing; available mounted on site or with separate packaging)
• WM-AU wall control (supplied with separate packaging)
• T-MB wall control (supplied with separate packaging) The CB-Touch control fitted on the unit allows moreover the control with the Sabiana Cloud WM” APP. This makes this fan coil unit the ideal solution for the air-conditioning of all residential ambients.

The CB-Touch control is equipped with a microprocessor with WiFi feature, that allows to control at distance or remotely all the units installed in your home.
With the WiFi technology you can switch on or off the fan coil units, set the operation mode, the air flux direction and the desired temperature value.
It is moreover possible to manage each single unit or to create some groups; a weekly program can be created by setting, for each day of the week, until four different operation modes. Just a WiFi connection is required to use the application and to download our “Sabiana Cloud WM“ APP, that is compatible with the iOS® and Android ™ systems.

The CB-E and CB-Touch controls fitted on the unit, whose characteristics are described at p. 22, can be supplied either fitted on the unit or with separate packaging; those controls fitted on the unit that are separately bought can be used only with UP power unit to buy separately.
The WM-AU and T-MB wall controls, whose characteristics are described from p. 23, are electronic controls that allow to manage one single unit or a group of units (only with the use of a power unit for each unit); the WM-AU and T-MB controls can be bought only separately and can be used only with UP-Touch power units to buy separately.
The room temperature can be controlled through the Sabiana electronic room thermostats and are suitable whenthe user wants to set the fan speed.

CONTROLS
Controls fitted on the unit features
CB-E control fitted on the unit features

The CB-E control can be used only with a programmable thermostat not supplied by Sabiana. It allows to switch on and off the unit (Stand-by) and therefore to easily set the ventilation by progressively acting on the fan speed, leaving the temperature control to a centralised programmable thermostat or to a thermostat for the home automation system, which, in addition to enabling fan operation, will also control the opening and closing of the water valve on the connection pipe.

After a period of 3 minutes since the last action the brightness of the panel is reduced (SLEEPING mode) in order to increase the energy saving and the comfort during the night; only the symbol is shown on the display.
By pressing the same button twice, the brightness is restored.

CB-Touch control fitted on the unit features

The CB-Touch control allows to control and adjust the room temperature in a simple and intuitive way by means of a probe positioned in the lower part of the unit.
CB-Touch allows to select the desired operation mode, heat, cool or just ventilate the room, set a desired temperature set and adjust the fan operating speed according to your needs.
On the one hand the maximum operation speed must be set to reach quickly the comfort temperature. On the other hand the minimum speed must be set when a noiseless operation is required.
With the low temperature cut-out thermostat (T3 sensor collocated between the coil fins; already wired for the units with fitted control, included together with the power unit and to wire for the versions without control) and according to the selected operation there will be as follows:

• winter cycle – the fan will only start operating if the water temperature is above 30°C, thus preventing cold air from flowing out from the unit.
• summer cycle – the fan will only start operating if the water temperature is below 21°C, thus preventing hot air from flowing out from the unit.

To improve comfort, it is also possible to select the night mode which minimises the fan speed and smartly changes the set temperature independently.
The control has a memory, so all settings will not be lost either in the event of switching off or power failure.
After a period of 3 minutes since the last action the brightness of the panel is reduced (SLEEPING mode) in order to increase the energy saving and the comfort during the night; only the symbol is shown on the display.
By pressing the same button twice, the brightness is restored.
The control is designed to be managed at distance with the smart features of one’s own telephone by using the bluetooth wireless connection or wifi via APP downloadable from the Web.
