THE PATENT
2x1 by Galletti: Evolution in air conditioning
Only someone who has been designing and manufacturing heating and air conditioning units for 45 years could have conceived a product which transcends
the limits of existing technology.
2x1 is an indoor unit for hydronic heating and cooling systems which combines two operating modes in a single unit.
Thanks to an exclusive patented design, 2x1 can function as a heater without the aid of a fan, exploiting instead the principle of natural convection.
In summertime 2x1 offers the advantages of the best fan coil units, cooling, dehumidifying and filtering the air inside the room.
The exclusive patent combines 2 different operating modes in a single unit:
2 different air flow routes inside the unit and 2 distinct heat exchangers make it possible to switch over from natural convection heating to ventilated cooling
or heating.
Heating: 3 operation mode, 5 thermal emission levels:
> 1st level - convection heating mode, fan off, flap open. The thermostat
controls the room temperature by acting on the valve (optional), which
interrupts the flow of water. The unit can be shut down immediately by
positioning the air outlet flap in the closed position.
> 2nd level - convection heating mode, fan speed set on extra low, flap
open. The thermostat controls the room temperature by acting on the fan
and valve (optional), which interrupts the flow of water.
> 3rd /4th //5th level - fan coil mode, fan speed on low, medium or high, flap
closed. The thermostat controls the room temperature by acting on the
fan and valve (optional), which interrupts the flow of water.
COOLING: 1 OPERATING MODE, 4 LEVELS OF COOL AIR DELIVERY
> 1st /2nd /3rd /4th level - fan coil mode, fan speed set on EXTRA-LOW, low,
medium or high, flap closed.
The thermostat controls the room temperature by acting on the fan and
valve (optional), which interrupts the flow of water.

CONSTRUCTIVE FEATURES
> CABINET WITH A REFINED DESIGN
- Front panel made of sheet steel, colour RAL9010. The front panel
incorporates an exclusive air flap which activates the convection heating
mode. The flap is opened and closed manually.
- Side panels manufactured from UV-stabilised ABS to maintain the colour
intact over time.
- Upper grill made of ABS (UV stabilised), adjustable louvers and flap.
The flap features a microswitch that automatically shuts down the unit
when the flap itself is closed. The side doors provide access to the
control panel and compartment housing the plumbing connections.
The doors may be secured by screws to prevent opening.
> HEAT EXCHANGERS
2X1 incorporates 2 heat exchangers for 2 distinct operating modes.
- 4-row convector exchanger made up of copper tubing and aluminium
fins secured to the tubing by mechanical expansion, complete with
brass manifolds and air vent valve. The wide spacing between fins
optimises the draught effect during natural convection.
- Fan coil exchanger, made up of copper tubing and high-efficiency
aluminium fins submitted to a hydrophilic surface treatment, secured
to the tubing by mechanical expansion. The exchanger comes
complete with air vent valves.
- The heat exchangers are normally connected in series, so that the 2x1
unit will be ready for installation in 2-pipe systems.
By removing the connecting pipe, 2x1 can be immediately converted
for installation in a 4-pipe system, where the convector exchanger will
be connected to the heating circuit and the fan coil exchanger to the
cooling circuit.
- The plumbing connections are normally provided on the left side but
may be switched over to the other side (180°) during unit installation.
> FAN ASSEMBLY
Including centrifugal fans with staggered airfoil-shaped blades,
manufactured from anti-static ABS.
The fans are housed in a low-noise ABS volute distinguished by a compact,
high-efficiency profile.
Four-speed electrical motor, mounted on vibration damping couplings,
directly connected to the fans, with permanently activated capacitor and
winding thermal protection .
> BEARING STRUCTURE
Bearing structure built from galvanised sheet steel of adequate thickness,
insulated by means of Class 1 self-extinguishing panels, supplied with an
installation kit (wall screws).
A support terminal board for electrical connections is located on the
bearing structure, on the opposite side of the plumbing connections.
> AIR FILTER
Honey-comb polypropylene washable air filter, mounted on a galvanised
sheet frame protected by a net, easily removable for maintenance
operations. The filter may be secured to the unit by means of screws.
> ACCESSORIES
- Speed switch
- Microprocessor panel for automatic control of the unit and the
connection to the ERGO control system
- Base support panels which conceal the pipes leading up from the floor
- Water flow regulating valves
- BIOXIGEN ionisation and purification system

The electrical connections indicated must be made by the installer. For each
fan coil an (IL) switch should be mounted on the power supply, with opening
contacts at a distance of at least 3 mm and a suitable protection fuse (F) .

ACCESSORIES
CK Speed switch, installation on the unit.
Control panel for installation directly on the unit, featuring a selector for setting
the fan speed (4 speeds) and shutting down the unit.
MICROK - advanced microprocessor control panel.
Microprocessor control panel to be installed on the
wall or directly on the unit, complete with speed
selector, electronic thermostat and cooling/heating
changeover switch, suitable for connection to an
ERGO supervision system.
It controls the fan speed and regulates the room
temperature in the heating and cooling modes.
-
Room temperature control in both the heating
and cooling modes, achieved by switching the
fan off and on, at the manually set speed.
-
Room temperature control in both the heating and cooling modes, with
automatic fan speed adjustment.
-
Timer (where installed in the unit).
-
Cooling/heating switching in the following modes:
manual, on the unit;
remote, manual (centralised);
automatic, depending on water temperature;
automatic, depending on air temperature.
-
Control of ON/OFF valves.
MICROK is also equipped with
-
input for remote enabling or disabling of unit operation
-
input for remote enabling or disabling of the ECONOMY set point (only for
systems controlled by ERGO software)
-
Sensor for air and water temperature reading
-
Optoisolated RS 485 communication port. No electricity supply required.
-
Integrated MODBUS communication protocol
-
INTEGRATED pull-up and pull-down resistors which may be activated via
jumpers.
ZK - Two support covering feet
Supplied in pairs, they comprise supports for
fastening to the base unit and outer coverings
for fastening to the cabinet.
They are used to conceal the plumbing (pipes
leading up from the floor) and in cases where
the fan coil unit cannot be anchored to the wall.
The height of the base support panels is 100
mm.
BV - Auxiliary water drip tray for vertical
installation units, enabling collection of
condensate from balancing/regulating valves.
VK - ON-OFF 3-way motor driven valve, with
hydraulic kit
The ON/OFF motor driven 3-way/4 collection VK
valve kit controls the room temperature by
stopping the water flow through the heat
exchanger.
VK kit includes:
Brass 3-way valve / 4 connections with built-in
by-pass, maximum operating pressure 16 bar;
Electrothermal actuator with the ON/OFF functions (total opening time 4
minutes), 230 V power supply.
Plumbing kit for installing the valve on the heat exchanger, complete with 2
holders for balancing and regulating the fan coil unit.
