USER INTERFACE
3.1
Preliminary notes
Operating statuses:
-
“on” status (the device is powered and is on; utilities
may be on
-
stand-by” status (the device is powered but is switched
off via software; utilities are off
-
the “off” status: the device is not powered; utilities are
off.
Hereafter, if the POF parameter is set to 0, with the word
“switch-on” means the passage from “off” status to “on”
status; the word “switch-off” means the passage from “on”
status to “off” status.
If the POF parameter is set to 1, with the word “switch-on”
means the passage from “stand-by” status to “on” status;
the word “switch-off” means the passage from “on” status
to “stand-by” status.
When the power is switched back on, the device displays the
status that it was in at the time it was disconnected.
3.2
Manual switch on/off of the device
If the POF parameter is set to 0:
1.
Connect/disconnect the device power supply.
If the POF parameter is set to 1:
2.
Make sure that the keyboard is not locked and that no
procedure is in progress.
3.
Touch the
key for 4 s: the
LED will flash,
after which it will turn off/on.
3.3
The display
If the device is switched on, during normal operation, the
display will show the magnitude established with P5, except
during defrost, when the device will show the magnitude
established with d6 parameter.
If the device is switched off (“stand-by” status), the display
will be switched off; the
LED shall be on.
If the device is in "low consumption" mode, the display will
be switched off and the LED shall be on.
3.4

key to select a label.
4.
Touch the
.
The following table shows the correspondence between the
labels and the temperature displayed.
Label Displayed temperature
Pb1
if the P4 parameter is set to 0, 1 or 2, room
temperature
if the P4 parameter is set to 3, incoming air tempe-
rature
Pb2
evaporator temperature
Pb3
if the P4 parameter is set to 1, condenser tempe-
rature
if the P4 parameter is set to 2, critical temperature
if the P4 parameter is set to 3, outgoing air tempe-
rature
Pb4
CPT temperature
To exit the procedure:
5.
Touch the
key or do not operate for 60 s.
6.
Touch the
key.
If the evaporator probe èis absent (that is to say, if the P3
parameter is set to 0), the “
Pb2
” label shall not be displayed.
If the fourth inlet function is to be a multifunction inlet (that
is to say, if the P4 parameter is set to 0) the “
Pb3
” label
shall not be displayed.
If the fourth inlet function is not to be an outgoing air prove
(that is to say, if the P4 parameter is not set to 3) the “
Pb4
”
label shall not be displayed.
