1.10 OPTIONAL BOILER
CONTROLLERS.
The boiler is prepared for the application of a
cascade and zone regulator, zone manager and
external probe.
These components are available as separate kits
to the boiler and are supplied on request.
Carefully read the user and assembly instructions
contained in the accessory kit.
• The cascade and area regulator (Fig. 1-5) is
connected to the boiler using only two wires,
powered at 230 V and allows to:
- manage a hydraulic circuit with 2 mixed
zones (mixing valve); 1 direct zone; 1 Storage
tank unit and relative pumps;
- self-diagnosis system to display any boiler
functioning anomalies;
- set two room temperature value: one for
daytime (comfort temperature) and one for
nighttime (lower temperature);
- to manage the temperature of the DHW (with
a storage tank unit);
- to manage the boiler flow temperature de-
pending on the external temperature;
- to select the desired operating mode from
the various possible alternatives for each
individual hydraulic circuit:
- permanent operation in comfort temp.;
- permanent operation in lower temp.;
- permanent operation in adjustable anti-freeze
temp.
• Zone manager (Fig. 1-6). In addition to the
functions described in the previous point, the
zone manager panel allows to control all the
important information regarding operation
of the appliance and the heating system with
the opportunity of easily intervening on the
previously set parameters without having
to go to the place where the appliance is
installed. The climate chrono-thermostat
incorporated into the zone manager enables
the system flow temperature to be adjusted to
the actual needs of the room being heated, in
order to obtain the desired room temperature
with extreme precision and therefore with
evident saving in running costs. It also allows
to display the effective room temperature and
the external temperature (if external probe
is present). The zone manager is powered
directly by the cascade heat adjuster via 2
wires.
Cascade and zone regulator electric connection
or On/off chrono-thermostat (Optional).
Any
thermostat or On/Off environment chrono-ther-
mostat must be connected to clamps “E” and “F”
eliminating jumper X40 (Fig. 1-4). Make sure
that the On/Off thermostat contact is of the
“clean” type, i.e. independent of the mains supply,
otherwise the P.C.B. would be damaged. Any
cascade and zone regulator must be connected
by clamps 37 and 38 to clamps “M” and “O” on
the connecting terminal board in the boiler, ob-
serving the poles and removing jumper X40, (Fig.
1-4) connection with the wrong polarity prevents
the heat adjuster from working, although it will
not be damaged.
1.11 EXTERNAL TEMPERATURE PROBE.
The boiler is designed for the application of the
Room Thermostat (Fig. 1-7) which is available as
an optional kit. Refer to the relative instruction
sheet for positioning of the external probe.
The probe can be connected directly to the boiler
electrical system and allows the max. system flow
temperature to be automatically decreased when
the external temperature increases, in order to
adjust the heat supplied to the system according
to the change in external temperature.
The electric connection of the external probe
must take place on clamps G and J on the con-
nection in the boiler (Fig. 1-4).
By default, the external probe is not enabled. It is
necessary to set parameters “P14” and “P15” for
correct operation. The correlation between flow
temperature to the system and external temper-
ature is determined by the curves represented in
the diagram (parameter “P14”) and by setting the
offset (parameter “P15”) (Fig. 1-8).
N.B.:
if the external probe is connected to the
cascade regulator, boiler parameter “P14” must
be set at “0”, and external probe control is dele-
gated to the cascade regulator.
Note: this graph is prepared with the offset value (P15) at 30°C (default
value). By changing the offset value, the origin of the flow temperature
curve will also change accordingly.
Ex: with Offset = 40 the graph origin is 40 and not 30 °C.
