SAFETY PRECAUTIONS
Before installing the air conditioner, please read the following safety precautions carefully.
Installation and maintenance are to be performed by qualified persons who are familiar with local
code and regulation, and experienced with this type of appliance.
All field wiring must be installed in accordance with the national wiring regulation.
Ensure that the rated voltage of the unit corresponds to that of the nameplate before
commencing wiring work according to the wiring diagram.
The unit must be GROUNDED to prevent possible hazard due to insulation failure.
 Confirm that the unit has been switched OFF before installing or servicing the unit.

VERTICAL FLOW FAN COIL
THE NEW SHAPE OF WELLNESS
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. 2-pipes version
models can also be equipped with electrical heaters, from 0.8 to 3.0kW.
The AC2800/AC2800B controllers have been set according to the unit
configuration:
-cooling or heating for 2-pipes application (without auxiliary electrical heater)
-cooling or heating for 2-pipes application (with auxiliary electrical heater)
-cooling or heating for 4-pipes application
-2-way or 3-way valve with ON/OFF control
Activating all parameters and routines of regulation which optimise the operation of the unit.
Through AC2800 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 50 mini-chillers and
120 fan coils.

GENERAL CHARACTERISTICS
Design
The design, elegant and considered in all details, harmonises well with all types of interiors.
Covers, 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 realised 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 or right hand water connections, which can be easily switched in the field if
required. Connections are equipped with air vents and drainage valves.
Controllers
AC2800 Electronic controller (optional)
Among the features of AC2800 controllers are:
-Selectable temperature range: 10-30°C or 16-30°C ( through selecting J4, default: close/16-30°C).
-2-pipes/4-pipes model (through selecting J1 and J2).
-Auxiliary electrical heater enable/disable (only for 2-pipes model, through selecting J3, default:
open/disable, if enable, it output from terminal 5).
-Cool/heat mode.
-Fan speed can be set at high/medium/low.
-Sensor failure alarm.
-LEDs show running state:
1) The three blue LEDs show fan speed high/medium/low.
2) The dichromatic LED shows heat and cool mode: the red LED shows heat mode, the green LED
shows cool mode.
3) The red LED shows ON/OFF of the system.
4) The room sensor failure alarm: high speed LED blinks and shuts off all outputs.
The water sensor failure alarm: medium speed LED blinks and shuts off all outputs.
5) Mode conflict: the mode LED blinks and shuts off all outputs.
-Smart manager integration

GENERAL CHARACTERISTICS
AC2800B Electronic controller
-Temperature range: 16-30°C.
-2-pipes/4-pipes model (through selecting J1 and J2).
-Auxiliary electrical heater enable/disable (only for 2-pipes model, through selecting J3, default:
open/disable, if enable, it output from terminal 5).
-Cool/heat mode.
-Fan speed can be set at high/medium/low.
-Cold draft protection (under heat mode, the fan can run only when the water temperature is above 30°C).
-Sensor failure alarm.
-LEDs show running state:
1) The three blue LEDs show fan speed high/medium/low.
2) The dichromatic LED shows heat and cool mode: the red LED shows heat mode, the green LED
shows cool mode.
3) The red LED shows ON/OFF of the system.
4) The room sensor failure alarm: high speed LED blinks and shuts off all outputs.
The water sensor failure alarm: medium speed LED blinks and shuts off all outputs.
5) Mode conflict: the mode LED blinks and shuts off all outputs.
NOTES
1. Mode conflict: for 2-pipes model, when the system works on heat mode and the water temperature is
blow 25°C, or when the system works on cool mode and the water temperature is above 25°C, the system
considers it fault as the mode conflict. At the same time, the system will shut off all outputs and the mode
LED will blink.
2. For 4-pipes model, the water sensor is fixed on the pipe of hot water.

GENERAL CHARACTERISTICS
The AC2800 controller 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 carried out through the electronic
controller on board, the wall mounted installed thermostat or the infra-red handset.
Across AC2800, the units can be connected straight to Smart Manager, the McQuay hydronic systems
supervision solution. With reference to hydronic units, Smart Manger manages up to 50 mini-chillers and 120
fan coils.
