End
”
3.
Push “
SET
” key and the “
End
”
will stop flashing.
4.
Turn OFF the instrument
and then remove the “
HOT-KEY
”.
At the end turn the instrument ON
again.
NOTE:
the “
Err
” message appears in case of a failed programming operation. In this case push again
the
UP
button if you want to restart the upload again or remove the “
HOT-KEY
” to abort the operation
.
15.2
COPY PARAMETERS FROM A HOT KEY (DOWNLOAD PARAMETER
VALUES)
1.
Turn OFF the instrument.
2.
Insert a
programmed “
HOT-KEY
” into the 5
-PIN receptacle
and then turn the Controller ON.
3.
Automatically the parameter list of the “
HOT-KEY
” is downloaded into the Controller
memory, the
“
do
” message is blinking followed a by flashing “
End
”.
4.
After 10 seconds the instrument will restart working with the new parameters.
5.
Remove the “
HOT-KEY
”.
NOTE:
the message “
Err
” is displayed for failed programming. In this case turn the
unit off and then on
if you want to restart the download again or remove the “
HOT-KEY
” to abort the operation
.

ALARM RECOVERY
Probe alarms
“
P1
”
,
“
P2
”
,
“
P3
”
and “
P4
”
start some seconds after the fault in the related probe; they
automatically stop some seconds after the probe restarts normal operation. Check connections before
replacing the probe. Temperature alarms “
HA
”
,
“
LA
”
,
“
H2
” and “
L2
”
automatically stop as soon as the
temperature returns to normal values.
It is possible to reset the “
EE
” alarm by pressing any button.
The alarms “EA”, “CA” and “dA”
will automatically stop as soon as the digital input is disabled.
The optional buzzer can be muted by pressing any key if parameter
tbA=Y
.

APPLICATION NOTES
Pay attention to the positioning of the regulation probe. In fact, the XR60CHC can obtain the best
performances of the system under control when the regulation probe is placed by following these guidelines.
NOTE:
it is possible to change the sensibility of the energy reduction algorithm (
ErA=Aut
) by using the
parameter
tun
(tuning). In case of different temperature probe placement (respect to the ones depicted in the
following table), try to change
tun
value from
H
to
L
.
Ventilated applications
–
Evaporator placed on the back of the
refrigerated zone, ventilator placed above the evaporator
-
The regulation probe is normally placed in the outlet air flow from the
evaporator
-
The regulation probe can be placed both inside or outside the
ventilator pack, paying attention to avoid positions too near to the
motor of the ventilator
-
Sensibility for
ErA=Aut
algorithm to be set to
tun=H
Ventilated applications
–
Evaporator placed on the top side of the
refrigerated zone, ventilator placed on the outlet air flow from the
evaporator
-
The regulation probe is normally placed in the inlet air flow to the
evaporator
-
The regulation probe has to be installed outside the evaporator,
avoiding any contact with the metallic parts of the evaporator itself
-
Sensibility for
ErA=Aut
algorithm to be set to
tun=H
Static applications
–
Coolers without ventilators:
-
The regulation probe is normally placed at the side-wall of the
refrigerated zone, approximately from 30% to 50% (of the internal
height) from the bottom and 20% to 30% (of the internal width) from
the back
-
Sensibility for
ErA=Aut
algorithm to be set to
tun=H

BLUETOOTH COMMUNICATION
The controller implements a complete Bluetooth 4.2 communication embedded module. This gives the
possibility to create a wireless communication channel with external devices (for example with a mobile APP
able to recognize and decode the device). All controllers use a proper MAC-ADDRESS which is used both for
unique identification and communication. The maximum communication range is about 5 m. Over this distance
