Installing and Operating Instructions
12.1 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.
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
Message Cause
"P1" Room probe failure
"P2" Evaporator probe failure
"P3" Third probe failure
"P4" Fourth probe failure
"HA" Maximum temperature alarm
"LA" Minimum temperature alarm
"HA2" Condenser high temperature
"LA2" Condenser low temperature
"dA" Door open
"EA" External alarm
"CA" Serious external alarm (i1F=bAL) All outputs OFF.
"CA" Pressure switch alarm (i1F=PAL) All outputs OFF
"rtc" Real time clock alarm
rtF Real time clock board failure
14.1 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" "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.
