Auto-Set Function - Immergas VICTRIX 50 Quick Start Manual

Turn the knob to set the code number in the flashing area, and
press the knob for storing the code entered.
NOTE: e code number is : 1234
If the code is correct the words "INSTALLER OK" appear
on the display. In case of error the write "CODE ERROR"
is visualized.
INSTALLER C O D E E R R O R
OK
Attention: if any operation is executed for ten minutes the
code must be re-entered.
After the code is entered, all the parameters reported in the
tables from page 14 to page 18 can be modified.
e following menus are available in addition to the ones listed
in the "user" section of this manual:
- HYDRAULIC: for the settings related to the system reali-
zed;
- HEAT GENERATOR: to set the kind of boiler;
- CASCADE: to regulate the settings for the cascade functio-
ning;
- BUS: to set the BUS address;
- RELAY TEST: to activate the relays of the regulator ma-
nually;
- ALARM: to visualize the anomalies of the functioning;
- SENSOR ADJUSTMENT: to modify the temperatures
values of the sensors.

AUTO-SET function.

anks to this function, it is possible to set automatically
the presence of heating and domestic hot water circuits wich
sensors are connected to the regulator.
e AUTO - SET is activated after the switch on of the
appliance.
Automatic activation.
When the AUTO - SET function is activated, the sensors
are automatically registered for every regulator start-up. If the
first start-up is registered a change in the configuration of the
sensors can be effectued only manually or cutting off the power
supply to the regulator.

Anomalies signalling.
e cascade and zones regulator displays and stores every time
all the anomalies that happen.
ere are four different 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 specific 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 cutoff.
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.
