1 CONSTRUCTIVE FEATURES
Available in 6 models 2 pipes system , and 4 models 4 pipes system, the
water cassettes series CSW has the modularity 600x 600 and 900x900
suitable for the standard concealed installation
> HEAT EXCHANGER with high efficiency, made with copper piping and
high efficiency aluminum fins, complete with an air vacuum valve and
draining tube, connected to the auxiliary drip tray for the condensate
collection.
> Auxiliary drip tray ,supplied as a standard , collects the water regulation
valve condensation.
> ELECTRICAL MOTOR : 3 speeds with low Rpm ,and thermal protection
for the windings.
> CENTRIFUGAL FAN with backward blades extremely silent, statically
and dynamically balanced and coupled directly to the 3 speeds electric
motor.
> BEARING STRUCTURE with internal and external acoustic and thermal
insulation.
The basic unit is complete with pre-sheared holes for fresh air intake
and air ducting installation.
> CONDENSATE DRAINAGE PUMP: complete with a flow switch for the
collection of the drip tray condensation.
The drainage pump is complete with one way valve and timer to delay
the switch off, after receiving the flow switch signal to insure an
adequate drainage of the condensate present in the drip tray
> ELECTRICAL COMPONENTS:
- Timer for the drainage pump
- Electrical connection board to the wall mounted panel for the
automatic control of the water cassette and water regulation valve.
> ADJUSTABLE DIFFUSER. The diffusers inclination on the air outtake is
manually adjustable for all models
> FILTER : washable made of synthetic material, inserted in the intake
grilles on the front panel ,and is easy to remove for maintenance.
> OBBLIGATORY ACCESSORIES
3 ways valves with hydraulic kit for 2 pipes and/or 4 pipes systems. The
water regulation valve are 3 ways / 4 connections ,motorized On/Off , 230
V and intercept the hot and cold water after receiving the thermostat
signal .
The valves are complete with a hydraulic kit to connect it to the coil.
2 CONSTRUCTIVE VERSIONS:

For each unit provide a mains circuit breaker (IL), with opening
contacts separated by at least 3 mm and an adequate protection
fuse (F).
Connect the power cables to terminal box connectors in accordance with
the wiring diagrams and tighten firmly.
Make the electrical connections with the power supply disconnected, in
accordance with current safety regulations.
All the wiring must be done by qualified personnel.
Power inputs are shown on the rating labels on the units.

and heating mode, by means of fan start/stop, at a manually set speed;
- room temperature regulation both in the cooling and heating mode, by
means of the automatic regulation of the fan speed;
- cooling / heating mode selection in the following way:
- manual;
- automatic according to the water temperature;
- automatic according to the room temperature;
- control of the ON/OFF valves for 2 or 4 pipe system;
The MICRONET control panels are provided also with contacts for external
signals in order to enable or disable the unit operation.
- terminals for the connections with external signals in order to enable or
disable the unit operation;
- terminals for the connections with external signals in order to enable or
disable the ECONOMY set point (only if combined with ERGO software)
- air temperature probe
- water temperature probe
- RS485
- built-in MODBUS communication protocol
- Built-in Polarity and termination resistance
SW - Water temperature electronic probe for
MICROPROD
Water probe for the MICROPROD control panels:
automatic selection of the cooling/heating operation
mode.
Connected directly to the microprocessor control
panels, this probe measures the water temperature
inside the heat exchanger.
If the temperature registered is lower than 17°C the unit works in cooling
mode and the temperature range of the control panel will be referred to the
cooling mode (19 / 31°C); if the temperature registered is higher than 37°C
the unit works in heating mode and the temperature range of the control
panel will be referred to the heating mode (14 / 26°C).
If the temperature registered is between 17°C e 37°C the control panel will
disable the unit operation.
The SW water probe is included in the MICRONET kit.
VK - 3-way valve with ON-OFF motor and
hydraulic kit
The VK motor driven 3 way / 4 ports ON/OFF valve
kit, connected to the control panels for éstro fan
coil units allows the regulation of the room
temperature stopping the water flow into the heat
exchanger.
The VK kit is available in various versions for all the CSW both for the standard
(VK S) and for the additional DF (VK DF) heat exchangers.
The kit is made of:
3 way /4 ports valve with incorporated by-pass , made of brass, with maximum
operation pressure 16 bar.
Electrothermal actuator with ON/OFF action (total opening period 4 min.),
power supply 230 V.
Hydraulic connections kit for the connection of the valve onto the heat
exchanger, complete with 2 holders for the balancing and the interception
of the fan coil unit.
KP - Power interface for connection of up to 4
units to a single control panel
The KP master sleeve can be installed to control
with a single control panel up to 4 units
(connected in parallel).
This accessory is designed for installation on
a DIN drive, usually placed on electric board,
can be matched with all the CSW fan coil
versions.
