User interface and setting display
The main user interface has a LED display with a touch-keys pad.
The display is are arranged in three menus:
A
• READINGS menu (key (C) Fig.1)
Displays the system’s current readings, no changes to the
settings can be made in this menu.
• SETTINGS menu (key (D) Fig.1)
Containing all the parameters that the user can modify according to system requirements; these parameters are grouped
together in various sub-menus:
- USER menu (Password 000);
- INSTALLER menu (Password 030);
- ELECTRIC HEATER menu (Password 001);
• ALARM log (key (E) Fig.1)
The alarm log records ‘alarms’ and ‘pre-alarms’ caused by a
unit error and/or malfunction.
During normal opperation, the monitor displays the last parameter modified; if no other keys are pressed for at least
5 minutes, the monitor activates the screensaver mode
(this function can be set via the parameter (I) in the INSTALLER menu).
To display parameters and/or readings, 4 figures are used;
the first is the indicator i.e. a number allowing the user
to know which parameter or reading he is displaying (Fig.3).

In the heat pump models, there is the possibility to produce hot water for domestic use;
this production has it's own changeable setting and it's own band (parameters E, F user
menu); with this parameter you can make parameters E and F visible and usable.
To control the domestic hot water production, once this function has been activated, you
must use the digital input ID6. (Marked on the electric card enclosed with the TWS)
• 1, ENABLE the domestic water function
• 0, DISABLE the domestic water function
The CLOSED status of the clamp means the domestic water function is ACTIVE. This function is available from software version 3.7 (the software version is visible as a reading,
with index E). The minimum compressor functioning time, and the defrosting time, take
priority over the production of domestic water.

Selection logic for dynamic FORCE OFF
The adjacent diagram shows the logic
for the dynamic FORCE OFF function;
this logic enables optimal management
of electric in accordance with the unit's
operating heater limits.
Example:
The aim is to produce at domestic hot
water with a setpoint of 55° an air temperature of -10°. Based on the parameters entered in the example, FORCEOFF
will intervene at 45°.
The compressor will continue to work
until an output temperature of 45° is reached. At this point, it will switch itself
off (in compliance with the minimum ON
times) and the electric heater will be
used to bring the system up to 55°C.
WARNING: By setting operating limits
with maximum values the function is disabled and resistance management remains, as explained in the next chapter;
using the FORCE OFF dynamic logic,
integration resistance will be used even
when producing domestic water.

Managing the electric heater
The units with moducontrol offer the
possibility to manage an electric heater; this heater can be managed in
different ways:
• supplementary (the simultaneous
use of the heat pump and the electric
heater);
• anti-freeze, or replacement (the heat
pump compressor is switched off and
the electric heater alone is activated);
The operational specifications of both
modes are shown in the diagrams below.
The choice of supplementary or replacement mode depends on the
external air temperature, and in case
this falls below the threshold indicated in the relative diagram.

Table of alarms
The units have two types of malfunctioning
warning:
• pre-alarm
• alarm
The first type is indicated by the flashing of the
red indicator light on the display; by pressing
the bell key, you can display the alarm list (with
index and cause shown in the table below). A
pre-alarm remains such for 60 seconds; if the
condition that caused it does not disappear
within this time, it becomes an alarm. The
alarms are visualised in the same way as the
pre-alarms, apart from the fact that the fixed
red indicator light comes on. Before resetting
the unit, you are advised to contact the After
Sales Assistance. To reset the unit you must
switch it off then on again, using the standby
button.
WARNING
The pre-alarms can become alarms if:
• a period of time equal to, or longer than,
60 seconds passes in the pre-alarm condition
• the maximum number of pre-alarms in an
hour (five) is exceeded. In this case, each subsequent pre-alarm will be visualised direct-
ly as an alarm, and as such will cause the
machine to stop until its cause is eliminated.

card is used as a replacement for cards with SW up to version 3.6.
High pressure switch
This warning does NOT indicate the status of the high pressure
switch itself, but of the compressor contactor. The high pressure
switch acts directly on the compressor contactor. If the controller
controls the switch-on of the compressor, and the contactor is not
activated after 3 seconds, this signal appears. This alarm can also
be caused by a defect in the functioning of the transmission system
relay from the compressor contactor to the controller (indicated as
RAP in the wiring diagrams). If the contactor is deactivated while the
compressor is functioning, this warning reappears. AP.

Low output
This warning appears when the force gas temperature (SGP probe) exceeds the threshold set in the parameter. The pre-alarm condition is removed with the factory-set temperature (default 125°C).
This warning appears when the compressor delivery transducer is
not detected and the machine is set in heat pump mode, or the presence of the DCP is set.
This warning appears when the transducer detects a delivery pressure greater than the set threshold (default: 40 bar).
The pre-alarm condition is removed with the factory-set pressure
(default: 38 bar).
This warning appears when the defrosting probe is absent and the
machine is set in heat pump mode.
This warning appears when the compressor suction transducer is
absent and the machine is set in heat pump mode.
This warning appears when the compressor delivery transducer
detects a suction pressure lower than the factory-set threshold in
cool mode (default: 4 bar), or in heat mode (default : 2 bar). The prealarm condition is removed when the suction pressure exceeds the
envisaged intervention threshold (default equal to 2 bar). The low
pressure alarm is suspended in heat mode for 3 seconds from when
the compressor is switched on; it is permanently suspended during
cycle reverse.
Whenever the machine is powered, the control checks the behaviour
of the compressor once only, via the output control procedure. This
control can be deactivated by means of the dip-switch.
This warning appears if the contact of the thermomagnetic switch
protecting the pump is opened. MTP. This code is displayed only if the
card is used as a replacement for cards with SW up to version 3.6.
This warning appears whenever there is a capacity control due to the
set threshold being reached. The machine goes into lockout when
the maximum number of capacity controls allowed (default 5) is exceeded. With the inverter machine, it also indicates a capacity control
due to a high compression ratio.
This warning appears whenever there is a low pressure capacity
control. The machine goes into lockout when the maximum number
of capacity controls allowed (default 5) is exceeded.
This warning appears whenever there is a discharge temperature
capacity control. The machine goes into lockout when the maximum
number of capacity controls allowed (default 5) is exceeded.
This error is given by the inverter control card and is linked to compressor pickup current problems.

reverse was prompted by the capacity control threshold being exceeded due to the high temperature of the discharge gas (default 130°).
This pre-alarm does not cause the compressor to stop, and there is
no maximum number of interventions.
WARNING
Remember that the pre-alarms are reset automatically, but the alarms must be reset manually.
The alarms can be reset by means of the remote ON/OFF contact, if this is enabled.
From the ON position, move to OFF then back to ON within 5 seconds to reset the alarms; a maximum of 3 resets can be made each hour via
the ON/OFF contact.
You must first reset the alarms using the “R” button.
In the event of a lack of voltage, the alarms will be reset.
