GENERAL SAFETY DEVICES.
All electrical connections must be executed by a
professionally qualied and authorized techni-
cian in compliance with current standards and
all applicable laws and regulations.
Regulators electrical connection.
To reduce any trouble deriving from electroma-
gnetic compatibility, please pay attention to the
following rules:
- Electrical supply wires and bus data cables
must be layed separately using a minimum
distance of 2 cm.
- For cascade and zones regulators directly con-
nected to the electricity network, the electric
wires and the bus data cables must be layed
separately.
Picture 1: minimum distance for electric insstallation
- Toinstalllthe zonesmanagersaminimumdistan-To installl the zones managers a minimum distan-
ce of 40 cm must be kept from other electrical
appliances with electromagnetic emissions such
as timers (relays), engines, transformers, light
regulators, microwave appliances, tv, speakers,
computers, mobile phones, etc.
Picture 2: Minimum distance from other electric ap-
pliances
- A minimum distance of 40 cm must be kept
between cascade regulator and zones manager.
More cascade and zones regulators connected
through the bus data can be installed one next
to the other.

Recommended diametres and lenghts for the
cables.
- Screened cables are recommended for the bus
data network.
Recommended types: J-Y(St)Y 2 x 2 x 0.6
Max. lenght: 50 meters.
- e earth connection of the cable screening
must be done once only . It is not allowed to
ground the same cable in more than one point
(see picture 3-4).
- Electric supply cables Ø = 1,5 mm2.
- Low voltage cables (for example sensors) Ø =
0,5 mm2 max lenght 100 meters.
Picture 3: earth connection of the cable screening only
in one point.
A double earth connection cannot be eected in
case of star network of bus data.
Picture 4: Star network of bus data.
e earth connection must be eected on one
side of the star!
Do not earth connect!

Installation place.
a - Use without ambient probe.
If the ambient probe is not activated, the
appliance can be installed everywhere.
b - Use with ambient probe.
If the room thermostat is activated, the
appliance must be located at a height of
1,20-1,50 m and in a suitable position for
correctly measuring the temperature. For
this purpose an intermediate wall of the
coldest zone can be chosen.
e appliance must not be installed:
- in places directly exposed to sunlight.
- in the vicinity of appliances that produce he-
ath such as TV sets, refrigerators, wall lamps,
radiators, etc.
- on walls behind which there are heating pipes
or ues.
- on not insulated external walls.
- in corners or recesses, on shelves, or behind
the curtains.
- near entrance doors of not heated rooms.
Installation.
Aer opening the upper part, the wall support
can be xed in the required place with the screws
and plugs supplied.
e data bus cable must pass through the lower
opening.
Recommended connection cable: J-Y(ST)Y 2
x 0.6
Max lenght: 50 m.

Electrical connection.
e two wired data bus cable must be connected
to A and B terminals .
e connection must be executed respecting the
polarity. e display does not show anything
whenever polarity is not respected. Aer con-
necting electrically the zone manager, ret the
front cover till the clamping.
BUS address setting.
e connection between zones managers and
cascade regulator must be obtained through a
data bus cable with two wires. Since the zone
managers are connected in parallel to the data
bus cable, the data transmission requires a bus
address.
BUS address (zone manager).
e bus address classication between cascade
regulators and zone managers is dened by a
rigid scheme set by the producer as explained
in the following scheme:

Attention:
Double assignments of the same data bus address
cause errors during the data transmission and
faults of system adjustments.
- Bus address change.
To change a bus address, it’s necessary to follow
the procedures below :
1 - to cut o the bus data cable from the zone
Manager
2 - to x again the zone Manager pressing the
turnable knob till the bus address is visua-
lized.
3 - to insert the new bus address and conrm.

Cascade and zones regulator installation.
The cascade regulator is designed for flush-
mounted installation.
e xing is done turning clockwise the two
lateral screws (1).
Turn anti-clockwise for disassembling.
Electrical installation.
e electrical connection and wiring must be
done in the back side of the appliance as reported
in the following page scheme.
All the connection terminals inside the blue
area (X1) work with safety low voltage and they
have not to connect to the main supply voltage.
If this happens the appliance will destroy and
you will lose the warranty!
e connection terminals inside the red area (X2….
X4) work with the main supply voltage.
Warning:
- For the wiring of the appliance the bus data
and sensors cables must be layed separately
from electric wires. Sensor and bus data cables
cannot be layed together with electrical supply
wires of other electrical appliances.
- For the connection it is necessary to use the
special screwing connector (X1÷X4) provi-
ded.

Bus address (Cascade regulator).
In case that only one cascade regulator is in-
stalled, the bus address is always 10. With more
regulators connected (at least ve) the regulator
directly connected to the boiler must have the bus
address 10. For the other regulators, the addresses
must follow numbers 20, 30, 40 e 50.
