Wireless control unit 868MHz
U2W2E 230V 4/8/12 zones ETHERNET
The wireless control unit U2W2E - 230V - 868 MHz is smart
base station with no wires to manage room thermostats
(T2WB and/or T2WBD) and actuators (A542O2) in order to set
and keep the temperature in different rooms.
Thewireless control unit U2W2E - 230V - 868 MHz can deliver
the power to move actuators (A542O2) and it can install a
bidirectional communication with thermostats, throughout
the most recent 868 MHz radio technology.
This unit records and uses an important amount of measured
data to control singularly the room temperature, in order to
guarantee the maximum comfort.
The standard version is equipped with a technological
software, able to comply every management requirement with
current and next heating systems have; since this branch looks
constantly ahead, every software and settings update can be
done by inserting a MicroSD memory card. MicroSD slot is on
the bottom and the card is optional.
The wireless control unit U2W2E - 230V - 868 MHz has a RJ45
port and an integrated web server to manage and set remotely
via Internet with PC/smartphone/tablet.

dew point for heating/cooling floor applications
USE
The wireless control unit U2W2E - 230V is used in conditioning
systems for new buildings as well as renovations like houses,
offices, stores, etc…
Using the wireless control unit U2W2E - 230V the installation
time can be consistently reduced; that is a great benefit for
installers. The wireless control unit U2W2E - 230V is often
installed in manifold wall boxes. This product is developed for
the connection of 4-8-12 room thermostat (T2WB or T2WBD)
and 18 actuators (A542O2).
Wireless room thermostat installation (T2WB or T2WBD) is
very easy because no wiring is needed. The free tool
connection and the clear color codification allow to quickly link
wires (actuators, boiler, pump, etc.). All wires are placed in
specific guides, in order to have a clear and orderly
arrangement and a fast installation of the wireless control unit
U2W2E - 230V.
‘’Antifreeze’’ function
Every actuator outlet has protection function against freezing,
independently of the operation mode. As soon as the set
antifreeze temperature is overpassed (5 … 10°C), actuators
A542O2 of the corresponding heating zone are switched on,
until reaching the safety set temperature. “Antifreeze”
temperature can be set by the MicroSD card.
Pump protection function
The pump is periodically activated (default intervals are set) to
avoid any damage due to too long stops. During that time, the
LED pump is on.
Valves protection function
When valves are closed for long time (for example, out of the
heating season), they are cyclically open in every heated zone
to avoid mechanic blocks.
Monitoring the dew point
If the system has a dew point sensor (to purchase separately)
and humidity is measured, the valves of all circuits are closed
to avoid damages to surfaces because of the moisture. Dew
point sensor input is taken into account just in cooling mode.
Safety temperature limitation
If a temperature limiter (optional) is installed, when the critical
temperature (previously set) is overpassed, valves shut down
and they preserve fragile surface of floors.

Connection of many control units
In case of use of many control units in a conditioning system,
up to 7 control unit can be paired (Pairing), enabling global
parameters exchange. The connection is done via radio or by
means of BUS system (syBUS). The radio range has to be
followed in order to pair units wireless. If the range is not
enough, control units must be connected through the wired
system syBUS. The communication type is the master/slave
principle. All messages and actions are exchanged among
control units. The master unit monitors in a centralized way the
following functions:
CO input/output (if the pilot function is activated)
Boiler output
Pump output

CONNECTION OF ETHERNET Integration into the home network
Quick and easy implementation into the home network
System interface for creation of superior control system
Control via PC / Smartphone
Comfortable parameterization and initial setting of the
system via PC, smartphone or tablet
Maximum comfort felt in every room
Maximum comfort due to the web application
Intuitive web interface for a clear overview
Complete control over all functions
The connection into the can be carried out by means of an
Ethernet cable, linking the control unit to the router or directly
to the PC/laptop.
