ELECTRICAL CONNECTIONS 

The instruments are provided with screw terminal block to connect cables with a cross section up to 
2,5 mm

for the digital and analogue inputs. Relays and power supply have a Faston connection 

(6,3mm). Heat-resistant cables have to be used. Before connecting cables make sure the power 
supply complies with the instrument’s requirements. Separate the probe cables from the power 
supply cables, from the outputs and the power connections. Do not exceed the maximum current 
allowed on each relay, in case of heavier loads use a suitable external relay. 
N.B. Maximum current allowed for all the loads is 20A. 

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.

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.

ALARM SIGNALS 

Message  

Cause 

Outputs 

“P1”

“P2” 

Second probe  failure

“P4” 

Fourth probe  failure

“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 and fans restarts  

“EA”  

External alarm 

Output unchanged. 

“CA”  

Serious external alarm (i1F=bAL)  All outputs OFF. 

“CA” 

Pressure switch alarm (i1F=PAL)  All outputs OFF 

14.1

 

SILENCING BUZZER / ALARM RELAY OUTPUT 

If “tbA = y”, the buzzer and the relay are is silenced by pressing any key.  
If “tbA n”, only the buzzer is silenced while the alarm relay is on until the alarm condition recovers. 

14.2

 

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.
