(a) Heating mode
(heat pump only):
Pressing this key for more than
5 seconds allows you to activate
or disactivate the heating mode.
It is not possible to pass directly
from the heating mode to the
cooling mode: if the machine is
set on cooling mode, pressing this
key will have no effect; it is first
necessary to disactivate the cooling
mode.
(b) Cooling mode:
Pressing this key for more than 5
seconds allows you to activate or
disactivate the cooling mode. It is
not possible to pass directly from
the cooling mode to the heating
mode (only for heat pumps):
if the machine is set on heating
mode, pressing this key will have
no effect; it is first necessary to
disactivate the heating mode.
• If the accessory PR1 or a remote control
switch is installed, the unit can also
be switched on and off from the panel
positioned on the machine, but only if the
remote command is set in the On position.
The modes, on the other hand, can only be
changed via the remote control.
• During the normal working of the unit, the
display shows the temperature of the water
entering the unit.
(c) Selection mode:
By pressing this key for more than
5 seconds, the sign
r1
appears on
the display; this sign indicates the
set point of the water in cooling
mode. Pressing keys
(a)
and
(b)
allows you to look through all the
parameters, while pressing key
(c)
allows you to visualise the value of
the chosen parameter, which can
then be modified if necessary, by
pressing keys
(a)
and
(b)
.
NOTE >
• When the unit is in parameter modification
mode, if no keys are pressed for a few
seconds, the display begins to flash. If,
after 60 seconds from the activation of the
procedure, no key has been pressed, the
system returns to normal working mode,
without memorising any parameter changes
that have been made.
• The unit is switched off by disactivating the
cooling or heating modes.
• The display is made up of 3 figures with
the automatic visualisation of the decimal
point between -19.9 and +19.9°C; outside
this measurement range, the value is
automatically visualised without the decimal
point (although the unit itself always takes
into consideration the decimal part when
working). During normal working, the value
visualised corresponds to the temperature
read by the SIW probe (the temperature of
the water entering the evaporator).
(d) Saving mode:
By pressing this key, you can
memorise the changed parameters
and end the procedure of selection/
modification of the parameters.
(a) Heating mode
(d) Saving mode
(c) Selection mode
(b) Cooling mode
