Sets the minimum time the compressor stays on. The compressor is not shut-down unless it has been on for  the minimum time 
selected. 

Def.: 

F=0 (no minimum operation). 

Available on all models.

FGXW\VHWWLQJRUVDIHW\SUREH 
In the event of the 

FRQWUROSUREHIDXOWalarm (that is the ambient probe is short-circuited or disconnected) this parameter ensures 

the operation of the compressor until the fault is resolved. In practice, the compressor, not being able to be activated according to 
temperature (due to the probe fault), works cyclically with an ON time equal to the value assigned to parameter 

F (in minutes) 

and a fixed OFF time of 15 minutes. There are two values for 

F which create special conditions.  

If 

F = 0, in the event of an ambient probe fault, the compressor will be DOZD\VRII; 

if 

F = 100, the compressor will remain DOZD\VRQ; and the 15 minute off time is not considered. 

• 

For other values of C4, at the moment a probe error (

() is detected, the duty setting cycle starts from the current status of the 

compressor:  

1.  if ON, it remains ON for the set time (C4), considering the time it has already been ON; 
2.  if OFF, it remains OFF for the OFF time, again considering the time it has already been OFF. 

The time settings for compressor C1, C2, C3 are in any case always respected. 

 

• 

If the control probe error occurs when the control is defrost mode or continuous cycle, the control instantly exits this status and 
activates duty setting. To re-activate the defrost or continuous cycle operation, the ambient probe must be reset. Remember that 
in the event of ambient probe errors, manual defrosts can not be performed.  

If the probe error is no longer present, the machine returns to normal operation. The compressor again takes on the logic of the 
control, respecting the times C1, C2, C3. 

 

Def.: 0 (compressor always OFF in the event of ambient probe 
fault). 
Available on all models.

FFFRQWLQXRXVF\FOHGXUDWLRQ
This is the time in hours that the compressor stays continuously on in order to lower the temperature to the Set Point. This function 
is used when rapid product temperature drops are required, for example, after loading the store; in this phase the temperature can 
fall below the Set Point by the value set using parameter 

$+. If FF=0, continuous cycle is not enabled. The control exits the 

continuous cycle procedure after the time set for the parameter 

FF or when the minimum temperature has been reached (see 

PLQLPXPWHPSHUDWXUHDODUP, parameter $/).  
Def.: 4 (hours). Available on all models . 
 
FDODUPE\SDVVDIWHUFRQWLQXRXVF\FOH 
This is the time, in hours, that the temperature alarm is disabled after a continuous cycle. In practice, if the temperature of the 
refrigeration unit, after the continuous cycle, falls due to inertia below the minimum temperature level (Set Point - 

$/) the 

activation of the low temperature alarm is delayed for a time equal to 

F. Remember that at the minimum temperature (Set Point - 

$/) the continuous cycle is forced off. 
Def.: 2 (hours). Available on all models.
