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 forced on the water
output temperature, regardless of the value of this parameter.

The units check the working temperature (input or output), to which a safety threshold is connected,
and beyond which the compressor is switched off immediately and automatically; this threshold is cal-
led FORCE-OFF.
WARNING The following parameters
must only be modifi ed by qualifi ed
personnel authorised to install the
unit.
Parameters only visible in heat pump models
Parameters only visible in models set for
hot domestic water productio

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 identifi es 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 confi rm the modifi cation
by pressing the key in (Fig.9) again.
