Cascade And Zone Regulator - Immergas VICTRIX PRO 1 I Series Technical Sheet

VICTRIX PRO 1 I
47 CASCADE AND ZONE REGULATOR (CODE 3.015244)
47.1
The electrical connection is made with 2 wires powered at 230V
(diameter 1.5 mm ).
2
The connection to the boiler takes place with 2 BUS data cables
with maximum length of 50 metres and allows to:
• manage up to 8 appliances in cascade configuration (for ex-
ample 2 cascades of 4 boilers, where each cascade has its own
safety devices kit, or a cascade of 5 boilers + a cascade of 3
boilers, where each cascade has its own safety devices kit);
• manage a maximum of three zones (of which 2 may be mixed)
and a zone for the separate D.W.H. storage tank. Given that a
maximum of 5 cascade regulators can be coupled (of which
one, the so-called Master, will be connected to the boiler
P.C.B.), a total of up to 15 zone systems can be served (of which
10 eventually mixed) and 5 separate storage tank units;
• set two room temperature values: one for day (comfort tem-
perature) and one for night (reduced temperature);
• manage the temperature of the D.H.W. (with a storage tank
unit managed as zone with a pump);
• select the functioning mode for C.H. and D.H.W. for each
individual hydraulic circuit:
- comfort temperature functioning,
- reduced temperature functioning,
- adjustable antifreeze temperature functioning;
• manage the boiler flow temperature depending on the external
temperature with setting of the climatic curve;
• obtain information regarding the system:
- system temperature,
- operating mode,
- counter data,
- timer programme,
- pump operation status,
- operation and values of the variable inputs;
The cascade and zones regulator allows to manage, control and
program the functioning sequence of the connected boilers. It
can be cascade and programmed via parameters that allow to
guarantee ideal temperature conditions at all times of the day
and night for each individual day of the week, both for the C.H.
system and the D.H.W. system (VICTRIX PRO 1 I coupled to a
storage tank unit). The cascade regulator can be inserted inside
the electric control board present in the cabinet or recessed
inside a support that allows fixing to the wall.
N.B.: with cascade regulator installation it will be necessary to
remove the "X40" jumper included in the standard configuration
of the boiler P.C.B.
With cascade regulator installation it is also advisable to install
an external probe.
CHARACTERISTICS
• setting the functioning parameters:
- functioning times,
- system mode,
- domestic hot water,
- direct circuit, mixed 1, mixed 2,
- date and time;
• show on the display, via self-diagnosis system, any functioning
anomalies with error codes;
• show the date, time, day of the week and the boiler temperature
on the display;
• the regulator has a specific section for setting the solar system
parameters;
• the regulator has specific terminals for the variable inputs and
outputs, that need to be used based on the specificity of the
system.
Variable inputs
- the variable inlets can be used to send a dry contact of request
from one or more on/off room thermostats (the thermostats
can then control, for example, zone pumps, satellite substa-
tions, etc through relay boxes; when the thermostat calls, it
energises a relay which makes the pump/satellite substation
start up, and it also sends an output dry contact to the cascade
and zone regulator on the variable input);
- with a cascade of boilers, the common flow probe always uses
a variable input;
Variable outlets
- the solar pump always uses 1 variable outlet;
- the recirculation pump always uses 1 variable outlet.
