Sabiana take part to the Eurovent program of fan coil performance certification.
The official figures are published in the Eurovent web site (www.eurovent-certification.com).
The tested performances are:
• Cooling total emission at the following conditions:
- Water temperature +7°C E.W.T. +12°C L.W.T.
- Entering air temperature +27°C dry bulb +19°C wet bulb
• Heating emission (2 pipe units) at the following conditions:
- Entering water temperature +50°C
- Entering air temperature +20°C
- Water flow rate as for the cooling conditions
• Cooling sensible emission at the following conditions:
- Water temperature +7°C E.W.T. +12°C L.W.T.
- Entering air temperature +27°C dry bulb +19°C wet bulb
• Heating emission (4 pipe units) at the following conditions:
- Water temperature +70°C E.W.T. +60°C L.W.T.
- Entering air temperature +20°C
• Available pressure • Fan absorption • Water pressure drop • Sound power
The descriptions and illustrations provided in this publication are not binding: Sabiana reserves the right, whilst
maintaining the essential characteristics of the types described and illustrated, to make, at any time, without the
requirement to promptly update this piece of literature, any changes that it considers useful for the purpose of
improvement or for any other manufacturing or commercial requirements.

Introduction
Following many years of experience
in the field of heating and air conditioning,
Sabiana has developed a range of Maestro
fan coils for concealed installation and
connection to a duct system.
They supply a consistent air flow with static
pressure up to 160 Pa.
The fan assembly has 5 speeds, 3 of them
are connected.
A range of 5 models to fit most conditions
is available with the combination
of either 3 or 4 row heat exchangers
and 2 or 4 pipe configurations with
additional heat exchanger.
Construction features
CASING
Consists of self-supporting panels
in hot dipped galvanized steel, fitted with
a class 1 anticondensating insulation.
FAN SECTION
Consists of quiet centrifugal fans
in galvanized steel with two impellers
and a directly driven single phase,
four speed motor, 230V 50Hz, with capacitor,
insulation class B.
AIR FILTER
The filter is made of washable synthetic
polypropylene with galvanized steel frame
and mesh.
Easy access to the filter for cleaning operation.
On request is available a 48 mm synthetic filter,
G3, 84% efficiency.
HEAT EXCHANGER
Constructed in 3/8” dia expanded
copper tubes with aluminium fins.
The connections
are on the left hand side looking
from the air inlet of the unit
(see picture and drawing at page 4).
On request or on site the connections
can be moved to the other side.
The heat exchanger is not suitable
for use in corrosive atmosphere
or in environments where aluminium
may be subject to corrosion.

Example of calculation
of the emission at different
speeds and air pressure drops:
Model = MAESTRO 13
Speed
= medium
Available pressure = 80Pa
Define the air flow correction factor in TABLE 1
below
Correction factor = 0,55
Calculation of cooling emission:
From Diagram 1 define the “variation in %
of the emission” using the correction factor
calculated above
For Total emission = 0,66
For Sensible emission = 0,61
Using the table at page 8 (up to page 17 for
the different sizes) and having the following
conditions:
- Entering water temperature (°C) = 7
- Water drop (°C) = 5
The total emission with wet bulb air temperature,
of 21°C is:
Total emission = 7070W x 0,66 = 4666W
The sensible emission with dry bulb air
temperature of 29°C is:
Sensible emission = 5292W x 0,61 = 3228W
Calculation of heating emission:
Same procedure as for the cooling emission
using the Diagram 2 and the tables from
page 18 a page 20.

Modulating valve control board
(accessory)
3 points modulating valve
control board
A power board can be supplied as an accessory to the Maestro
unit, together with a control panel to be installed on the wall.
QCV 9034260
The power board is made up of an electronic control board, a power relay module for managing
the fan load and a 230/24 volt power transformer, all contained in a galvanised plate case to be
secured to the side of the unit. The power board can manage the correct operation of the fan
and water valves.
Power board
The technical specifications of the electronic power board are:
• Power supply – 230Vac, 50 Hz.
• Management of 2- or 4-pipe systems.
• Mode for setting the operating logic of the fan (continuous operation or operation when the
valves are open).
• Range of settings 10°C to 30°C.
• Modulating valve control output with 3 positions. The actuator opening time can be set by
hardware using the jumpers.
• Relay output for 3 speed fan interlocked with selector switch to correctly handle the loads.
• Voltage-free input contacts for connecting an occupancy or open window sensor.
• Possibility to connect T1 air temperature probe (included with the control) to be installed on
the return air intake.
• Possibility to connect T3 low temperature cut-out probe (included with the control).
In heating mode, the fan is off until the water temperature reaches 32°C.
• Possibility to connect T2 Change-Over probe (optional extra) for automatic Cooling/Heating
changeover in 2-pipe systems.
Wall-mounted control panel (included)
The control panel allows the following functions to be performed:
• switch the unit on/off
• set the set point
• display the temperature
• select the fan speed
• set the operating mode
The panel is wall-mounted and represents the interface with the unit.
It is fitted with a room temperature probe for the room temperature
control. During installation, the user can select whether to use the air temperature probe installed
on the return air intake, or alternatively the probe inside the control panel.

MaxiNet - supervisory software:
The electronic board used on our QCV appliances can be included in a network of Sabiana terminal
units (Futura – Slim – SkyStar) also fitted with IRC electronic boards. The entire network can then
be managed and supervised from a computer running our MaxiNet software.
For the units fitted with 3-point valves, the MaxiNet program can display, in addition to all the
operating parameters of the individual unit, the exact position of the actuator in the water valve.
