PROBE CONNECTION 

The probes shall be mounted with the bulb upwards to prevent damages due to casual liquid infiltration. 

It  is recommended  to place  the  thermostat  probe  away  from  air  streams  to  correctly measure  the 

average  room  temperature.  Place  the  defrost  termination  probe  among  the  evaporator  fins  in  the 

coldest place, where most ice is formed, far from heaters or from the warmest place during defrost, to 

prevent premature defrost termination.

HOW TO USE THE HOT KEY 

To enable the HOT-KEY port (5-pin connector), set the par. 

oAn=n

.  

17.1

 

PROGRAM A HOT KEY FROM AN INSTRUMENT (UPLOAD) 

1.

 

Program one controller with the front keypad. 

2.

 

When the controller is ON, insert the 

HOT-KEY

 and push 

UP 

button;  the 

uPL

 

message 

appears followed a by a flashing 

End

 label. 

3.

 

Push 

SET 

button and the 

End

 will stop flashing. 

4.

 

Turn OFF the instrument, remove the 

HOT-KEY

 and

 

then turn it ON again. 

 

NOTE

: the “

Err

” message 

appears in case of a failed programming operation. In this case push again 

button if you want to restart the upload again or remove the 

HOT-KEY

 to abort the operation. 

17.2

 

PROGRAM AN INSTRUMENT BY USING A HOT KEY (DOWNLOAD) 

1.

 

Turn OFF the instrument. 

2.

 

Insert a 

pre-programmed 

HOT-KEY

 into the 5-PIN receptacle 

and then turn the Controller 

ON. 

3.

 

The  parameter  list  of  the 

HOT-KEY

  will  be  automatically  downloaded  into  the  Controller 

memory. T

he “

doL

” message 

will blink followed a by a flashing 

End

 label. 

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.

BUZZER MUTING OR ALARM RELAY OUTPUT DEACTIVATION 

If 

tbA=Y

, the buzzer and the relay are silenced by pressing any key.  

If 

tbA=n

ALARM RECOVERY  

Probe alarms 

P1

” 

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 “
