ACCESSORIES
TA - Wall mounted room thermostat
Room thermostat for wall installation.
Automatic regulation of the room temperature:
- only in the heating mode working on the fan motor
assembly and on the regulating valve, if installed (ON/
OFF operation);
- only in the cooling mode working on the fan motor assembly and on the
regulating valve, if installed (ON/OFF operation);
- both in cooling and heating mode, with remote mode selection working on
the fan motor assembly and on the regulating valve, if installed (ON/OFF
operation).
TA2 - Wall mounted room thermostat with summer/
winter selector
Wall mounted room thermostat with cooling / heating
mode selector.
Automatic regulation of the room temperarure both in
heating and cooling mode, working on the fan motor
assembly and on the regulating valve if installed (ON/OFF operating).
CSD - Wall mounted control for proportional opening
and closing of the PA90 motorized louver
Designed for wall installation it allows the proportional
opening and closing from 0 to 100% of the PA90 outdoor
air intake motorized louver
MAF / MAFO - Air intake
modules with filter
Made of galvanized steel sheet,
these modules permit to filter the
air sucked up by the unit and also
to connect the unit to the intake
channeling.
2 version are proposed depending
on the guaranteed filtering degree:
MAF: air intake module with flat
filter made of acrylic material,
self-extinguishing in class 1, with filtering class G2.
MAFO: air intake module with corrugated filter made of acrylic fiber, self-
extinguishing in class 1, with filtering EU4.
PCOC - Connecting panel to
rectangular ducts
Manufactured in galvanised sheet
steel, the PCOC connection panels
are used for the connection of
rectangular ducts with flanges
and with other flanged
accessories. They can be
installed on both the intake and
delivery line.
They are made up of a rectangular
panel that is to be secured to the machine (or to another accessory with
similar drilling, for example, MAF, MAFO, RE etc..) coupled to a flanged
sleeve that represents the starting point for rectangular ducts of the type
commonly used in distribution plants.
PCOF - Connecting panel to
flexible ducts
Manufactured in galvanised sheet
steel, the PCOF connection panels
are used to connect to air
distribution plants achieved by
means of hoses or to other
dedicated accessories. They can
be installed on both the intake
and delivery line (in this case the
hose should be insulated).
They are made up of a rectangular panel that is to be secured to the machine
or to another accessory with similar drilling (i.e. MAF, MAFO, RE etc..)
complete with circular collars (Ø 200 mm) that represent the starting point
for the hoses of the type commonly used in distribution plants.

V - M - R 3-way valve, on-off actuator
and hydraulic connections kit
IThe system allows the regulation of the
ambient temperature by stopping the water
flow into the heat exchanger.
Available for 2 pipe and 4 pipe systems, the
kit is made of the components below indicated:
Valve body (V): 3-way with in-built by-pass
(4 connections):
- 3/4” for the models UTN 6, UTN 6A, UTN 8,
UTN 8A
- 1” for the models UTN 12, UTN 12A, UTN
16, UTN 16A
Actuator (M): normally closed, electrothermal
type, 230V single phase, with ON-OFF
operation, it works directly on the valve shutter.
Hydraulic connections kit (R): made of copper tubes and brass connections,
complete with balancing valve, is different according to the models (standard
coil or additional coil in case of 4 pipe systems) and for the unit water
connection side.
The hydraulic connections kit is not available for the UTN22 - 22A and UTN30
- 30A units.
VRCV / VRCH - Auxiliary trays for collecting condensate
Auxiliary trays for collecting condensate, used for collecting any condensate
that might form on the adjusting valves, the hydraulic unions and the
holdfasts during the cooling operating mode.
The trays are made of galvanized metal sheet, with condensate discharge
pipe (
φ
17 mm) setup for being connected to a flexible rubber tube, like that
which has been envisaged for the condensate discharge trays of the basic
unit.
They are available for:
UTN units installed vertically, VRCV.
UTN units installed horizontally, VRCH.
