JOLLY PLUS 2

CONSTRUCTION CHARACTERISTICS

SUPPORTING STRUCTURE: in galvanised high-thickness sheet, integrating structural and functional elements in plastic, such as the condensate tray and fan conveyor.

HEAT EXCHANGE COIL: copper tube arranged in staggered rows in order to increase heat exchange. Aluminium fins, fastened by mechanical expansion of the tubes. The manifolds intetgrate air vents and water drain holes. The coil has a pocket for the water temperature probe. The fan coils can be ordered with left or right connection. In case of need it is however possible to retate the coils. Conversion from left to right connection requires nevertheless an adapting kit.

CONDENSATE TRAY: in thermoplastic material -thus corrosion-free- supplied as a standards on models VM-G and VN. It permits either vertical and horizontal installation of the unit.

FAN MOTOR: the motor is a high-efficiency brushless type, speed-controlled. It is fitted on rubber supports to reduce noise transmission to the frame. Speed adjustment occurs on stepless mode. The units are also available on demand with compatibility to Ferroli 3 fixed speed control or pre existing ones.

TANGENTIAL FAN: the tangential-type fan is coupled directly to the motor and mounted on an anti-vibration support.

AIR FILTER: in polypropylene honeycomb, easily removable, it can be regenerated simply by washing with water.

CABINET (only VM-F and VM-G): entirely made in steel sheet and epoxy powder, coated to ensure high corrosion resistance. The air outlet grilles are on the top of the cabinet.

The side panels can be removed to ease the unit’s installation and access to its internal components.

Available in colour RAL 9003.

AIR OUTLET GRILLE (only VM-F and VM-G): in aluminium, painted the cabinet colour. It can be rotated to get the air flow towards the room or against the wall.

AIR INLET GRILLE

(version VM-F): in extruded aluminium. It includes two thermal actuators opening the grille in parallel with activation of the fan. A microswitch prevents fan operation when the grille is removed for periodic filter cleaning.

(version VM-G): also in extruded aluminium. It is mounted below the front panel and is fixed blades type. Removable for filter cleaning.

PLUMBING CONNECTIONS: the units are equipped with EUROKONUS ¾” plumbing connections, that allow simple and safe connection.

CONTROLS

Speed control can be made on progressive mode or on pre-set speeds

STEPLESS SPEED CONTROL

Specific controls - equipped with continuous regulation algorithms - have been developed. Such devices keep steady comfort conditions inside the room. Energy savings are also granted thanks to the fan modulation, as well as sound pressure minimization.

The electronics and its interface are available as on-board version (TC plus), supplied as a standard on the models on VM-F and VM-G. The unit can be however been ordered without built-in control: a remote one (TC-R plus) can be ordered separately as an accessory.

TC-R plus remote thermostat can also handle up to 31 fan-coil units connected together in parallel. This solution is suitable for medium-large rooms containing several installed units.

Functions: Room setpoint regulation / Automatic fan speed / Noise limiter (decreasing fan speed) / NIGHT mode (fan speed decrease / setpoint modification) / MAX (brings speed fan to max)

Connections: 230 V output for ON-OFF valves / Independent voltage-free contacts for activation of a chiller or boiler depending on room thermostat request / Voltage free contact for room presence (window opening contact or hotel badge).

PRE-FIXED SPEED CONTROL

In case a 3 speed-control is wished to be used, the interface TD-3R is available, for remote in-wall installation. The accessory needs to be ordered separately. Jolly Plus models which are compatible with the mentioned interface can however be coupled with 3-speed thermostats which may be already present in the installation.
