HOW TO PROGRAM AN INSTRUMENT USING A HOT KEY
(DOWNLOAD)
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 “doL” 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” and “P2” 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” and “LA” automatically stop as soon as the thermostat
temperature returns to normal values and when defrost starts.
Alarms “EA” and “CA” (with i1F=bAL) recover as soon as the digital input is disabled.
Alarm “CA” (with i1F=PAL) recovers only by switching off and on the instrument.
