■LOCAL CONTROL
In each room there is a sensor to measure
the temperature which can also control the
system simply:
•± 3°C with respect to the set-point
•switch off the system
• set the antifrost
■ CENTRALISED CONTROL OF THE WHOLE SYSTEM
(UP TO 99 ZONES)
Thanks to the temperature control unit the
whole system can be controlled with a single
command.
It is like having 99 timer thermostats in a single
device.
■JUST ONE CONTROLLER TO PROGRAM
The temperature control unit allows quick
programming thanks to its large display,
navigation of the simplified menu and
keypad like that of a mobile phone.

TYPE OF SOLENOID VALVE
In a hydraulic system the zones are built up physically
using solenoid valves. Each zone can thus be
managed independently by controlling the individual
solenoid valves.
2 types of solenoid valves are used in the systems:
•ON/OFF, which requires an ON/OFF contact
•Open/Close, which requires an Open/Close contact
ON/OFF solenoid valve Open/Close solenoid valve
Installing the solenoid valves in the collector box
PLACING THE SOLENOID VALVES
In heating systems the typical installations has all the
solenoid valves positioned on the collector, grouped
in a box in the boiler room. In dwellings on several
floors this solution can be replicated for each floor.
In fan-coil systems the solenoid valve can be installed
inside the fan-coil itself.
In 2-tube systems there is just one solenoid valve
for both the heating and cooling functions. In 4-tube
systems there are 2 solenoid valves, one each for the
heating and cooling functions.

PLACING THE SOLENOID VALVES IN RADIANT
PANEL SYSTEMS
Radiant panel systems are always managed in zones
and their solution is very similar to that of radiator
systems.
The zones are built up by means of solenoid valves
grouped on the collector, but there is also a water
mixture valve.
This valve is proportional and cannot be controlled by
the My Home temperature control.
This valve mixes the water so that a set water
temperature limit and thus floor temperature limit
is not exceeded, which could be annoying and
dangerous.

SYMBOL LEGEND
Radiant panels Three-way mixing valve
M
For this reason this valve must be controlled by a unit
supplied by the panel system manufacturer, or it is
simply a thermostatic valve on which a fixed water
temperature limit is set.

MY HOME
temperature control
APPLICATION DEVICES
A My Home temperature control system can manage
up to 99 zones. The system is on a 2-wire bus and
made up of the following devices:
Temperature control unit:
this configures the system, customises the programs
and displays information.
Sensors:
at least one sensor must be installed in every zone.
They measure the room temperature and can locally
vary the temperature set on the control unit.
Actuators:
operate the solenoid valves and the circulation
pumps. The number and type of actuators are chosen
depending on the type of solenoid valves installed and
their location in the system.
Just one contact is used to control the ON/OFF solenoid
valves, while the two-relay interlock is used for the
open/close solenoid valves. The four-relay actuator
controls the fan-coils and also automatically controls
the 3 speeds.
The ideal system solution is to have the solenoid
valves grouped on the collector, so that a board
can be made containing the actuators near the
box.
This makes wiring simpler with a small number of
actuators.

1) Graphic display: shows the messages which guide the programming
operations and the system state.
2) Navigation keypad: allows navigation within the menus and confirms or
deletes programming operations.
3) Alphanumeric keypad: allows manual entry of all those programming
operations which require the use of numbers and/or symbols.
4) Battery compartment: housing for battery item 3507/6.
The Control unit, which can only be used for the BTicino temperature
control function, can set the system and modify the system mode of
operation. Equipped with management software with guided menus shown
on the display, it allows the user to chose the mode of operation, display
the temperatures of the various zones and display and modify the daily
temperature profiles and the weekly programs, while the maintenance
menu, reserved for the installer (password protected), allows access to the
system settings (zone configuration, system test, total reset, etc.).
