VERTICAL FLOW FAN COIL
THE NEW SHAPE OF WELNESS
The new series F of fan coil with vertical air flow is characterised by flexibility in performance and quiet
operation to offer a total wellness. It represents one of the most cost effective solutions to provide a
comfortable environment for both commercial and residential applications.
The series features 8 sizes, with cabinet for floor or wall installation and
chassis for concealed installations.
The units are available in the 2-pipes version with 3 or 4-rows coil –
nominal cooling capacity from 1.3 to 8.0kW; nominal heating capacity from
2.2 to 12.0kW – or in the 4-pipes version – nominal cooling capacity from
1.2 to 8.0kW; nominal heating capacity from 2.3 to 13.0kW.
The AC2800A electronic control (optional) allows, in its standard
configuration, both the regulation of all functionalities and units operating
modes and the connection into a network in Master & Slave configuration
up to 16 units.
The control module has been designed to automatically set up according to the unit configuration:
 cooling or heating for 2-pipes application
 cooling or heating for 2-pipes application with electrical heater
 cooling or heating for 4-pipes application
 with/without 2-way or 3-way ON/OFF regulating valves
activating all parameters and routines of regulation which optimise the operation of the unit.
Through AC2800A units can also be directly integrated with Smart Manager, McQuay solution for the
supervision of hydronic systems. With reference to Fan Coils, Smart Manager run up to 256 units and 120
zones.

GENERAL CHARACTERISTICS
Design
The design, elegant and considered in all details, harmonizes well with all types of interiors.
Cover, grids and cabinet materials have been selected with a special care to grant both the quality of the
finishing and the durability of the product.
Cover and grids are realized in ABS, RAL103; the cabinet is made of pre-painted sheet metal finished with
high quality paint, RAL1013.
Filter
The filter, located at the bottom of the unit, is easily accessible and self-locking, therefore no tools are
required for removing and re-assembling it.
The filter material grade is G1 and thanks to its pleated surface grants a filtration surface up to 60% greater
than traditional filters resulting in lower pressure drop and reduced noise emission.
Connections
Units are available with left hand water connections, which can be easily switched in the field if required.
Connections are equipped with air vents and drainage valves.
Controls
AC2800A Electronic control (optional)
Among the features of AC2800A control are:
 Selectable temperature interval: 10-30°C or 16-30°C according to the application
 Auto restart after power failure based on last temperature and mode setting
 Timerwith2dailysettings(14weekly)
 Change-over heat/cool, based on control system signal
 Warm and cold draft protection
(this feature stops the fan when the set-point condition is satisfied and the water temperature is too warm
does not cause discomfort to the room occupants)
 Antifreeze protection
(this function ensures that the room temperature is kept above a minimum level; if the unit is in off mode,
and the room temperature drops below 9°C, antifreeze protection is enabled and the unit temperature
rises above 11°C. At this point the unit is switched off again.)
 Ambient temperature sensor incorrect operation
 Air temperature sensor
(this is unit-mounted – if the control is wall-mounted, a second air sensor located in the control can be
used for fine tuning of the desired room temperature.)
 Valves 2 or 3 ways with ON/OFF control
 Smart manager integration
Besides the led present on the cover allow an immediate display of the unit operation status - fan speed,
operating mode, ON/OFF - and at the same time they are used with auto-diagnosis function.

GENERAL CHARACTERISTICS
The AC2800A control can be connected straight to Fan Coil Network, without any further components; in
fact the electronic board has integrated the NIM Module [ Network Interface Module].
The Network allows to control from a unique place al the operating parameters of the connected units.
The general control is executed through the Master unit and can be carry out through the electronic control
on board, the wall mounted installed thermostat or the infra-red handset.
Across AC2800A, the units can be connected straight to Smart Manager, the McQuay hydronic systems
supervision solution. With reference to hydronic units, Smart Manger manages until 256 units and 120
zones.
