4.5 - Parameters description
F01 - Control differential (hysteresis)
It is the difference of temperature (hysteresis) between to turn OFF and turn ON the refrigeration
output.
Exemple:
To control the temperature in 4.0°C with differential of 1.0°C. Soon, the refrigeration will be
turned off in 4.0°C and turned on again in 5.0°C (4.0+1.0)
F02 - Minimum setpoint allowed to the end user
F03 - Maximum setpoint allowed to the end user
Electronic limits whose purpose is prevent that too high or too low setpoint temperatures are
regulated.
F04 - Delay when the instrument is powered on
When the instrument is powered on, its control is kept disabled during a time, delaying the start of
process. During this time, it works only as temperature indicator. It serves to prevent demand of electric
energy peaks, in case of lack or return of the same and when exists a lot of equipment connected on the
same net. For this, just adjust different times for each equipment. This delay may be of compressor or
defrost (when exist defrost on turn on).
F05 - Offset indication for ambient temperature sensor
Allows it to compensate for eventual ambient temperature (S1) misreading, usually due to a sensor
replacement.
F06 - Offset indication for evaporator sensor
Allows it to compensate for eventual evaporator temperature (S2) misreading, usually due to a sensor
replacement.
F07 - Operation mode of digital input 1 (*)
F08 - Operation mode of digital input 2 (*)
Allows to choose between the following peration modes of digital inputs:
0 - disabled
1 - open door signaling, NC contact;
2 - defrost by external sync, NC contact;
3 - pressostat status , NC contact;
4 - open door signaling, NO contact
5 - defrost by external sync, NO contact;
6 - pressostat status , NO contact.
Note:
1 - When a door opens, the Buzzer sounds (by means of the conditions set in F38 and F41), and the
“FANS” output will be turned off. The screen will keep showing .
2 - When an external sync defrost event occurs, the manual defrost will be forced on.
3 - When a pressure switch event occurs, the “COMP”, “FANS” and “DEFR” outputs will be turned off. The
screen will keep showing .
F09 - Evaporator temperature (S2) for fan return after draining
After the draining, the fan-delay cycle starts. The refrigeration (COMP) output is turned on, because the
evaporator temperature is high, but the fan only is turned on after evaporator temperature decreases the
adjusted value. This process is necessary to remove the heat that exists in the evaporator because the
defrost, preventing to pass it to the ambient.
F10 - Maximum time of fan return after draining (fan-delay)
For security, if the evaporator temperature does not reach the adjusted value in F09 or the S2 sensor is
detached, the fan-delay will happen after passed the adjusted time in this function.
F11 - Minimum time of compressor turned on
It is the time that the compressor will keep turned on, it means, the time period between the last started and
the next stopped. It serves to prevent high voltage from the mains.
F12 - Minimum time of compressor turned off
It is the minimum time that the compressor will keep turned off, it means, the time period between the last
stopped and the next started. It serves to alliviate the pressure and to increase the useful life of the
compressor.
F13 - Compressor status with detached ambient sensor (S1)
If the ambient sensor (S1) is detached or out specified range, the compressor assumes the configured
status in this function.
Exemple:
For counters that storage fruits it is better that the compressor keeps turned off, but in counters
that storage meats it is better that the compressor keeps turned on.
F14 - Fan on with compressor off (refrigeration)
During refrigeration, the fan can be depend of the compressor status.
”0” = The fan keeps turned on while compressor is turned on (this alternative, in some cases,
Possibilities a great economy of electrical energy).
”1” = The fan keeps turned on during all refrigeration cycle.
F15 - Fan stop for high temperature in evaporator
This function cycles the evaporator fan until that ambient temperature approaches of the temperature
desired in the refrigerating installation project. This preventing high temperature and suction pressures
that can damage the compressor. If the temperature in evaporator pass the adjusted value, the fan is
turned off, turning on again with a configurable hysteresis in F16. Valuable resource when refrigeration
equipment that had been inactive for a few days or refrigerated cases are restocked with its proper
merchandise.
F16 - Fan return hysteresis (after stopping due to high evaporator temperature)
This allows for determining the temperature difference for the fan to resume operation after stopping
due to exceeding the desired temperature in the evaporator.
F18 - Evaporator temperature to start defrosting (if F22=1)
When the evaporator temperature reaches the value set in this function the controller starts to count the
time to confirm a low S2 temperature to start defrosting (F19).
F19 - Time to confirm a low S2 temperature to start defrosting (if F22=1)
When the evaporator temperature drops and then reaches the value set in F18, the controller starts to
count the confirmation time to start defrosting. During this step, if the temperature remains low the
controller starts defrosting. Otherwise, if the temperature rises by at least 1°C above the setpoint, the
system continues in the refrigeration mode.
F20 - Maximum time with compressor turned on without reaching the set point (to warn)
If the time set in this function is exceeded while the compressor is on and the setpoint is not reached,
the display will show . This indication will disappear when the compressor is turned off.
F21 - Defrosting type
0 - Electric defrosting (by resistance), where only the defrost output is activated
1 - Defrosting by hot gas, where the compressor output and the defrost output are activated
F17 - Maximum time in refrigeration mode (for safety reasons, if F22=1)
This acts as a safety time when the function "defrost by temperature" is enabled (F22 = 1), and the
evaporator temperature does not reach the value set in F18. This function determines the maximum
time the controller will remain without perform defrosting.
F22 - Condition to start defrosting (**)
This defines whether defrosting will start by time, by temperature or by scheduling:
0 - time (cyclic)
1 -
temperature
2 - schedule (RTC)
F23 - Interval between defrosts (if F22=0)
This determines the time the instrument will wait between defrosts, with the time being counted from
the last defrost. Defrosting will only be started if the S2 temperature (evaporator sensor) is below the
temperature indicated in F27.
F24 - Time for collecting the gas before the start of the defrost cycle
After starting the defrost the controller will keep only the fan on for this time to use the remaining
energy of the gas.
F25 - Delay before performing the 1st defrost (if F22=0)
This function allows extra time for the instrument to remain in the refrigeration mode before performing
the first defrost cycle to avoid defrosting several chambers at the same time. This time is shown only
before the first defrost cycle when F22=0 (start defrost by time).
F26 - Defrost when the instrument is powered on
It possibilities the defrost at the moment that the controller is turned on, for example, in return of electrical
energy (in case of energy lacks).
