1.11 OPTIONAL BOILER CONTROLLERS.
e boiler is prepared for the application of a cascade and zone
regulator, zone manager and external probe.
ese 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.
ATTENTION:
disconnect power to the appliance be-
fore any electrical connection.
• e cascade and area regulator (Fig. 6) 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 anoma-
lies;
- 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 ow temperature depending on the exter-
nal 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. 7). 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. e climate chrono-thermostat
incorporated into the zone manager enables the system ow
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 eective room temperature
and the external temperature (if external probe is present). e
zone manager is powered directly by the cascade heat adjuster
via 2 wires.
ermoregulation electrical connection (Fig. 5).
ermoregulation electrical connections must be carried out on
the boiler terminal board eliminating jumper X40.
- ermostat or On/O environment chrono-thermostat: must
be connected to clamps “E” and “F”. Make sure that the On/O
thermostat contact is of the “clean” type, i.e. independent of the
mains voltage, otherwise the P.C.B. would be damaged.
- Cascade and zone regulator: must be connected through clamps
37 and 38 to clamps “M” and “O” respecting polarity. e connec-
tion with incorrect polarity will not damage the thermoregulator,
but will not allow it to operate.
If the cascade and zone regulator is used, it is com-
pulsory to set up separate lines with dierent power
supply voltages, particularly it is essential to separate
the very low voltage connections from the 230 V ones.
No boiler pipes must ever be used to earth the electric
system or telephone lines. Ensure elimination of this risk before
making the boiler electrical connections.
1.12 EXTERNAL TEMPERATURE PROBE OPTIONAL.
e boiler is designed for the application of the external temper-
ature probe (Fig. 8), which is available as an optional kit. Refer to
the relative instruction sheet for positioning of the external probe.
e probe can be connected directly to the boiler electrical system and
allows the max. system ow 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.
e electric connection of the external probe must take place on
clamps G and J on the connection in the boiler (Fig. 5).
By default, the external probe is not enabled. It is necessary to set
parameters “P14” and “P15” for correct operation. e correlation
between ow temperature to the system and external temperature
is determined by the curves represented in the diagram (parameter
“P14”) and by setting the oset (parameter “P15”) (Fig. 9).
In case “P32” is bigger than “P15”, “P32” will be the minimum limit for the set.
In case “P32” is lower than “P15”, “P32” will not be considered.
e external probe may be used with the cascade and
zone regulator by connecting it on the regulator or on
the boiler (attention: the code of the external changes if
it is connected to the regulator or the boiler); for specic
installations refer to the diagrams on page 40. If the external
probe is connected to the cascade regulator, boiler parameter
“P14” must be set at “0”, and external probe control is delegated
to the cascade regulator.
