MULTI CONTROL panel user interface
The MULTI CONTROL accessory
makes it possible to control and
manage up to 4 chillers (equipped with
MODUCONTROL circuit board). This
accessory allows the user to manage:
• Switching units ON/OFF (according
to the management logic selected).
• Reading chiller parameters (Working
temperatures and pressures, working
set-point, etc...).
• Time periods (the system allows
to set up to two daily time periods,
diversified by days of the week).
• Domestic hot water (domestic hot
water production, DHW hourly program,
anti-legionella cycle, etc...).
• Functioning modes (heating or
cooling mode).
• Alarm log (the system allows to
record the last 10 alarms triggered in
the system).
Attention: the use of one or more
additional VMF-CRP modules is
required to use some functions, as
indicated in the system layouts.

Main MULTI CONTROL display
During normal operation of the system,
the MULTI CONTROL accessory
display shows the standard window.
This window contains information on
the system status and this information
will allow the user to have a clear
indication regarding functioning of the
chillers as well as supply any error and/
or malfunctioning messages.
Should the user enter a menu and not
press any key for a time longer than
that set in the screensaver function, the
system will automatically return to view
the main screen.

UNIT SYNOPTIC menu procedures
The first window of the UNIT SYNOPTIC menu allows the user
to monitor the status and settings of the chillers installed in
the system; this window displays the following information:
- Chiller currently selected (1): indicates which chiller the
displayed data refers to (1st, 2nd, 3rd or 4th chiller).
- Active functioning mode (2): indicates which functioning
mode is currently set on the chiller selected; the symbols
which may be viewed are:
- (chiller mode = WINTER).
- (chiller mode = SUMMER).
- Chiller status (3): indicates the status of the chiller
currently selected; the symbols which can be viewed are:
- the icon ( ) indicates that the chiller is on;
- the icon (
OFF
) indicates that the chiller is off;
- the icon (
SB
) indicates that the chiller is standby mode;
- the icon ( ) indicates that the chiller pump is on;
- the icon( ) indicates that the chiller is not communicating
with the modbus network of the system;
- the icon ( ) indicates that the chiller has an alarm;
- the icon ( ) indicates that the chiller is defrosting.
- Water outlet temperature ( 4): indicates the temperature
of the water currently produced by the selected chiller. If the
chiller has a fault, the icon ( ) will be replaced by the icon (
). Furthermore, in place of the temperature value, there will
be the alarm code currently active. By pressing the key Fa
reset control can be sent to the faulty unit.
- Current work setting (5): indicates the work setting
currently used by the chiller selected.
From this window it is possible to:
(1) Select one of the chillers of the system:
by pressing the key Cthe number of the chiller currently
selected is highlighted ( 1); after which pressing the key A
will pass on to the subsequent chiller, while pressing the key
Bwill select the previous chiller; press the key Cto confirm
the choice.
(2) Enable or disable the selected chiller:
by pressing the key D, the chiller can be enabled or
disabled; the icons above the key Dwhich represent these
two states are:
- (represents the ENABLED status);
- (represents the DISABLED status).
If the unit is ENABLED, it will be managed based on the
settings supplied by its work set point and by the eventual
hourly program associated; if on the other hand this unit is
DISABLED, it will be forced to remain in the OFF status until it
is enabled once again.
(3) Pass on to the next window:
to go to the next window of this menu, press the key B.

The third window of the UNIT SYNOPTIC menu allows the
user to set daily time periods (maximum of two for each day
of the week) for the chiller currently selected; once the time

displayed data refers to (1st, 2nd, 3rd or 4th chiller); this choice
can ONLY be modified on the first page of this menu.
- Day of the week ( 2): indicates which day of the week is
managed by the specified time periods.
- First time period ON ( 3): indicates the time at which the
first time period must start.
- First time period OFF ( 4): indicates the time at which the
first time period must end.
- Second time period ON ( 5): indicates the time at which
the second time period must start.
- Second time period OFF ( 6): indicates the time at which
the second time period must end.

If this relation is not respected,when all the
data has been entered a “DATA ERROR”
message will appear on the display,
disabling the entire daily time period.
If you would like to delete one or more time
