VICTRIX 50
General features.
e Cascade and zones regulator allows the user to control, monitor
and program the operating sequence of the generators connected. e
regulator can be set-up and programmed using parameters that gua-
rantee ideal temperature conditions at all times of the day and night
and throughout every day of the week for both the heating system and
domestic hot water system (when VICTRIX 50 is used in conjunction
with a water heater). e cascade and zones regulator can be tted into
a support axed to a wall.
e electrical connections are made with 2 wires powered at 230V
(1.5 mm2 ) in diameter.
2 BUS data cables up to 50 meters in length are used to connect to the
boiler, allowing the device to:
• control up to three zones (2 of which mixed if necessary) and a sepa-
rate water heater unit. Since up to 5 cascade regulator can be installed
(of which only one, the so-called Master, will be connected to the
boiler board), systems with up to a total 15 zones (of which 10 mixed
if necessary) and 5 separate water heater units can be controlled;
• enter two ambient temperature values, one for the daytime (comfort
temp.) and one for the night (lower temp.);
• control the temperature of the domestic hot water (in conjunction
with a water heater Unit);
• select the operating mode for the heating and hot water production
functions of each individual hydraulic circuit:
- comfort temperature mode or low temperature mode, adjustable
antifreeze temperature mode;
• control the boiler delivery temperature according to the outdoor
temperature (in conjunction with the external probe), with climatic
curve settings;
• obtain information about the system:
- temperature of the system, operating mode, meter data, timer
program, pump operating status, variable input values and ope-
ration;
• enter the operating parameters:
- operating times, operating mode, domestic hot water, direct, mixed
1, mixed 2 circuits, date and time;
• display operating faults with their relative error codes by means of
the check-control system;
• display the date, time, day of the week and temperature of the gene-
rator.
e Zone manager only operates in conjunction with the Cascade
and zones regulator. Besides the functions described for the Cascade
and zones regulator, it allows the user to keep all the important infor-
mation concerning the operation of the appliance and heating system
under control and particularly ready to hand. is means that the
previously set parameters can be easily modied without having go
go to the place where the cascade regulator is installed. the climatic
timer-thermostat built into the remote control panel allows the sy-
stem's delivery temperature to be adapted to the eective needs of the
place being heated so as to obtain the required ambient temperature
with the utmost precision and, thus, with evident savings in running
costs. e controller also allows the ambient temperature and eective
outdoor temperature to be displayed (this latter if the external probe
is installed). e zone manager is powered by the cascade regulator
by means of 2 BUS data cables up to 50 meters in length are used to
connect to the boiler, allowing the device to:
• control up to one zone;
• enter two ambient temperature values, one for the daytime (comfort
temp.) and one for the night (lower temp.);
• control the temperature of the domestic hot water (in conjunction
with a water heater Unit);
• select the operating mode for the heating and hot water production
functions of each individual hydraulic circuit:
- comfort temperature mode or low temperature mode, adjustable
antifreeze temperature mode;
• control the boiler delivery temperature according to the outdoor
temperature (in conjunction with the external probe), with climatic
curve settings;
• obtain information about the system:
- temperature of the system, operating mode, meter data, timer
program, pump operating status, variable input values and ope-
ration;
• enter the operating parameters:
- operating times, operating mode, domestic hot water, direct,
mixed 1, mixed 2 circuits, date and time;
• display operating faults with their relative error codes by means of
the check-control system;
• display the date, time, day of the week and temperature of the
generator.

e cascade and zones regulator displays and stores every time
all the anomalies that happen.
ere are four dierent types of anomalie:
1 - Sensor anomalies signalling.
e values of the sensors resistance that are out of range
are considered as fault. According to the specic function
the faults are indicated by code 10…20; according to the
type of fault, code 0 indicates the short circuit and code
1 signals the cuto.
2 - Control errors signalling.
ese errors codes estimate the result of the regulations.
ese anomalies are indicated through codes 50….60 and
index 0, 1 or 2.
3 - Bus errors signalling.
ese codes signal possible address errors such as a double
address or the non-recognition of a bus address. ese ano-
malies are indicated through code 70 and index 0 or 1.
4 - Boiler electronic card errors signalling.
ese error codes are related to the boiler electronic card
and they are divided in two types: operational anomalies
with manual reset with code E-XX (see instruction manual)
and operating anomalies with electric reset (automatic re-
set) with code B-XX (see instruction manual).
Errors management:
- anomalies are visualized on the regulator display.
- system anomalies are visualized in the information level with the
related value.
- if necessary the errors are saved in the error register (see de-
scription below).
- setting the parameters properly, the errors activate an error signal-
ling output for the connection to an optical or acoustic signal.
