Characteristics of the regulation
The command panel of the unit allows
the rapid setting of the working para-
meters of the machine, and their vi-
sualisation. The display consists of 4
figures and various LEDs for indicating
the type of operational mode, the visua-
lisation of the parameters set and of any
alarms triggered. The card stores all the
default settings and any modifications.
With the installation of the PR3 remote
panel accessory, it is possible to control
the switching on and off from a distance,
as well as the setting of the operational
mode (cooling-heating), and the visua-
lisation of the alarm summary. After the
absence of voltage for any period of
time, the unit is able to start up again
automatically, maintaining the original
settings.

The main user interface is represented by a LED panel with
capacitive keyboard (touch keys); the visualisations are ar-
ranged in three menus:
• READINGS menu (key (C) Fig.1)
Containing the information (visualisation mode only) relating
to current unit functioning.
• SETTINGS menu (key (D) Fig.1)
Containing all the parameters that the user can modify accor-
ding 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 unit error and/or malfunctioning condi-
tions (whether alarms or pre-alarms).
During normal functioning, the monitor visualises the last pa-
rameter 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 visualising (Fig.3).

Readings menu
To access the readings menu, press
the key in (Fig.4); once the readings
menu has been accessed, the monitor
will display the readings index and a
3-character string that identifies it; the
string will be displayed for one second,
after which it is replaced by the value
of the reading itself. To move on to the
next reading, press the key in (Fig.5); to
go back to the previous one, press the
key in (Fig.6). Every time you pass from
one reading to another, apart from the
change in the index value you will also
see (for one second) the string identi-
fying the current reading (it is possible,
however, to identify any reading via the
value of the indicator, comparing it with
the table below).

USER menu
To access the USER menu, press the
key in (Fig.7). Once the key has been
pressed, you must insert the password
to access the various menus; to access
the user menu, the password is 000 (di-
splayed by default). To modify the value
of the passwords, use the arrow keys.
When you have inserted the correct
password, press the key in (Fig.7). The
monitor will show the index of the USER
parameter and a 3-character string that
identifies it; the string will be displayed
for one second, after which it is repla-
ced by the value of the parameter itself.
To move on to the next parameter, use
the arrow keys (Fig.8). To modify a pa-
rameter, just select it, press the key in
(Fig.7), modify the assigned value using
the arrow keys in (Fig.8), and confirm
the modification by pressing the key in
(Fig.7) again.

This parameter indicates the proportional band applied to the hot domestic water set;
this band produces the optimised management of the compressor, only switching it on if
the inlet/outlet water temperature (depending on the type of control set by parameter
(0) in the installer menu) is less than the hot domestic water set (parameter (E) user

INSTALLER menu
To access the INSTALLER menu, press
the key in (Fig.9). Once the key has been
pressed, you must insert the password
to access the various menus; to access
the user menu, the password is 030.
To modify the value of the passwords,
use the arrow keys. When you have in-
serted the correct password, press the
key in (Fig.9). The monitor will show the
index of the INSTALLER parameter and
a 3-character string that identifies it; the
string will be displayed for one second,
after which it is replaced by the value
of the parameter itself. To move on to
the next parameter, use the arrow keys
(Fig.10). To modify a parameter, just se-
lect it, press the key in (Fig.9), modify
the assigned value using the arrow keys
in (Fig.10), and confirm the modification
by pressing the key in (Fig.9) again.

The machine adjustment will depend on the value of this parameter:
• if 0, the machine adjustment is based on the output temperature;
• if 1, the machine adjustment is based on the input temperature;
• if 2, the machine adjustment is based on the temperature of the remote probe,
as read on the DHW panel (in the event of a fault on the remote probe, the machine
adjustment is based on the built-in probe, signalling this fact via alarm code 157).
If the production of hot domestic water is activated, the adjustment is automatically for-
ced on the water output temperature, regardless of the value of this parameter.

The units possess an advanced logic for controlling the processed water temperature;
the complete check prevents the system arriving at a point of equilibrium at a higher or
lower temperature compared with the one set in the work setting. Remember that an
increase in the integration time weakens the effect of the integral control.

In the units, it is possible to set a safety control on the water output temperature; on the basis of the value assi-
gned to this parameter, the anti-freeze electric heater is managed as follows:
• value 0, anti-freeze electric heater absent;
• value 1, anti-freeze electric heater installed and working only with machine in heat or cool mode;
• value 2, anti-freeze electric heater installed and working also in standby, but switching on the pump;
• value 3, anti-freeze electric heater working in standby without the pump being activated;
• value 4, with external air temperature less than 3°C, the pump is activated for 2 minutes every 30, to moni-
tor the temperature of the water throughout the system.

This setting configures the type of control applicable to the units; depending on the value
decided for this setting, the controls on the functioning mode (HEAT/COOL) and the unit
on/off command will be managed in the following way:
Set value 0:
• Setting functioning mode = set parameter 0
• ON/OFF control = from the panel on the machine
Set value 1:
• Setting functioning mode = set parameter 0
• ON/OFF control = from the remote panel
Set value 2:
• Setting functioning mode = set from remote contact
• ON/OFF control = from the panel on the machine
Set value 3:
• Setting functioning mode = set from remote contact
• ON/OFF control = from the remote contact
Enabling domestic water

In the heat pump models, there is the possibility to produce hot water for domestic
use; this production has its own modifiable setting and its own band (parameters E, F
user menu); with this parameter you can make parameters E and F visible and usable.
Remember that to guide the domestic water production request, once the function has
been activated you must use digital input ID6 (marked on the electric card enclosed with
the unit as TWS). Remember also that setting this parameter with a value of:
• 1, you ENABLE the domestic water function
• 0, you DISABLE the domestic water function
The CLOSED status of the clamp means the domestic water function is ACTIVE. This fun-
ction 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. From software version 4.2, when domestic
water is activated the adjustment is automatically set on the basis of the output temperatu-
re, regardless of the value of the parameter (0) in this menu.

Setting the supplementary electric heater or activating the boiler
Index - String MIN
value
MAX
value Parameter function
04
This parameter indicates which logic must be used to manage the supplementary
electric heater; the choice of logic is determined by the value set in this parameter so,
depending on the value, the settings are:
0 = no supplementary electric heater present on the unit
1 = supplementary electric heater present, but cannot be activated during hot domestic
water production
2 = electric heater activation command used as consent for activation of an external boiler
3 = supplementary electric heater present and active during hot domestic water production
4 = electric heater activation command used as consent for activation of an external
boiler which can also be used in supplementary mode
WARNING:
• on the SRP V1 units, it is ABSOLUTELY FORBIDDEN to set this parameter value at (3);
• to set the value at (4), the DHW accessory is needed.
