13. HOW TO USE THE HOT KEY
13.1 HOW TO PROGRAM A HOT KEY FROM THE INSTRUMENT (UPLOAD)
1. Program one controller with the front keypad.
2. When the controller is ON, insert the “ Hot key ” and push
o
key; the "uPL" message
appears followed a by flashing “End”
3. Push “ SET” key and the End will stop flashing.
4. Turn OFF the instrument remove the “Hot Key”, then turn it ON again.
NOTE : the “ Err ” message is displayed for failed programming. In this case push again
o
key
if you want to restart the upload again or remove the “ Hot key ” to abort the operation.
13.2 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.
14. ALARM SIGNALS

Cause Outputs
“P1” Room probe failure Compressor output acc. to par. “Con” and “COF”
“P3” Third probe failure Outputs unchanged
“P4” Fourth probe failure Outputs unchanged
“HA” Maximum temperature alarm Outputs unchanged.
“LA” Minimum temperature alarm Outputs unchanged.
"HA2" Condenser high temperature It depends on the “Ac2” parameter
"LA2" Condenser low temperature It depends on the “bLL” parameter
“dA” Door open Compressor according to rrd
“EA” External alarm Output unchanged.
“CA” Serious external alarm (i1F=bAL) All outputs OFF.
“CA” Pressure switch alarm (i1F=PAL) All outputs OFF
“rtc” Real time clock alarm Alarm output ON; Other outputs unchanged;
Defrosts according to par. “
IdF ” Set real time clock

service
14.1 ALARM RECOVERY
Probe alarms P1 ”, “ 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 ” “ HA2 ” and “ LA2 ” automatically stop as soon as the
temperature returns to normal values.
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.
14.2 OTHER MESSAGES
