F01 - Access code 123 (one hundred and twenty-three):
This is required to change the configuration parameters. Entering this code is not required to see the
adjusted parameters.
It allows you to enter the following access codes:
[,123]
- Allows you access for changing the table parameters
[,231]
- Allows you to configure the unit of measurement
[,=F,]
or
[,=C,]
F02 - Sensor indication displacement (offset):
Enables compensation for any temperature deviations resulting from sensor replacement or change in the
cable length.
F03 - 1st stage operation mode:
Selects the 1st stage operation mode (OUT1):
[,,,0]
- Cooling
[,,,1]
- Heating
F04 - Minimum setpoint allowed to end user (1st stage):
Prevents accidental setting of extremely low setpoint temperatures.
F05 - Maximum setpoint allowed to end user (1st stage):
Prevents accidental setting of extremely high setpoint temperatures.
F06 - 1st stage control differential (Hysteresis):
Difference in temperature (hysteresis) between turning the refrigeration (or heating) ON and OFF.
Example:
You want to control the temperature at 4.0 °C with a differential of 1.0 °C. Therefore, the
refrigeration will be turned off at 4.0 °C and turned on again at 5.0 °C (4.0 + 1.0). In the heating mode the
output goes off at 4°C and turns on again at 3° (4.0-1.0), according to graphs below:
8.5.1. Description of parameters
F07 - Delay to turn the 1st stage output on:
The minimum time during which the 1st stage output remains off, i.e., the time interval between the last stop
and the next start. It relieves the discharge pressure and increases the service life time of the compressor. This
delay also occurs when starting up the device. In facilities with several equipment units, assigning different
values to the delay time at the start up of each device will allow for demand peaks to be avoided when the
devices are activated at different times.
This function can be turned off by setting it at the minimum value 0
[No,,]
.
F08 - 2nd stage operation mode:
Selects the 2nd stage operation mode:
[,,,0]
- Cooling
[,,,1]
- Heating
[,,,2]
- Cyclic timer
[,,,3]
- Absolute extra-range alarm: Considers the values defined in
[,F15]
and
[,F16]
as minimum
and maximum values to activate the alarm output.
[,,,4]
- Extra-range alarm relating to the 1st stage setpoint: Considers the 1st stage setpoint and the
absolute values defined in
[,F15]
and
[,F16]
, i.e., the positive value of these functions as minimum and
maximum values to activate the alarm output. Limits: (

F09 - Cyclic timer/alarm time base (F08=2, 3 or 4):
Allows setting of the time bases to turn the OUT 2 output on and off when the 2nd stage is set in cyclic
timer or alarm modes. The possible settings for output time on and output time off are, respectively:
[,,,0]
- Seconds/Seconds
[,,,1]
- Seconds/Minutes
[,,,2]
- Minutes/Seconds
[,,,3]
- Minutes/Minutes
F10 - Cyclic timer/alarm on time (F08= 2, 3 or 4):
Allows setting of time the controller remains with OUT 2 output on when the 2nd stage is set in cyclic
timer or alarm modes.
F11 - Cyclic timer/alarm off time (F08= 2, 3 or 4):
Allows setting of time the controller remains with OUT 2 output off when the 2nd stage is set in cyclic
timer or alarm modes.
F12 - Initial cyclic timer status (F08= 2):
Allows you to choose whether the cyclic timer starts on or off.
[On,,]
- Connected
[Off,]
- Disconnected
NOTE:
The OUT 2 output will take this status whenever the cyclic timer resumes operation.
Example:
By the end of delay to turn the 2nd stage output (F18) on, when exceeding the value set in
F14 or exiting the cyclic timer status on while OUT1 output is on (F08=2).
F13 - Cyclic timer always on while OUT1 output is on (F08=2):
Keeps OUT2 output always on while OUT 1 output is on. This is recommended for milk coolers, where
the cyclic timer commands the stirrer, which remains activated while cooling is activated.
[no,,]
- Stand-alone cyclic timer
[yes,]
- Cyclic timer always on while OUT1 output is on. When OUT1 output is off the timer will cycle
according to times set in F10 and F11.
F14 - Minimum temperature to turn the cyclic timer off (F08=2):
This is the minimum temperature in which the cyclic timer will work; below this limit, the cyclic timer is
turned off. It is recommended for milk coolers, to allow the stirrer to operate without excessive load, thus
avoiding the engine burning out.
NOTE:
Function F14 has priority over F13.
F15 - Minimum allowed setpoint/Low temperature alarm (2nd stage):
F16 - Maximum allowed setpoint/High temperature alarm (2nd stage):
When the 2nd stage is defined as thermostat (F08 = 0 or 1), these are the electronic limits. The purpose
of this is to avoid unintentional regulation of extremely high or low setpoint temperatures. When the 2nd
stage is defined as alarm (F08 = 3 or 4), these are the electronic limits of low
[atlo]
and high
[atHi]
temperatures, respectively. The differential for turning off the alarm is set at 0.1°C/1°F.
For safety reasons, the 1st stage output will switch off if a high temperature alarm
[athi]
is activated
when configured for heating, or if a low temperature alarm
[atlo]
is activated when configured for
cooling. For this reason, you must configure the alarm threshold above (if heating) or below (if cooling)
the desired temperature (setpoint of the 1st stage).
F17 - 2nd stage control differential (Hysteresis) (F08 = 0 or 1):
This is the temperature difference (hysteresis) between turning the cooling (or heating) ON and OFF.
F18 - Delay to turn on the 2nd stage output (F08 = 0.1 or 2):
This is the minimum time during which the 2nd stage output remains off, i.e., the time interval between
the last stop and next start. This delay also happens when the device is started-up. This function can be
turned off by setting it at the minimum value 0
[No,,]
.
Note:
If the 2nd stage is set as cyclic timer (F08=2), this delay will only occur at the device start-up.
F19 - Alarm inhibition time when connecting the controller (F08= 3 or 4):
This function is used to inhibit the alarm for a period of time when the system has not yet reached the
operating temperature.
This function can be switched off by setting it at the minimum value 0
[No,,]
.
F20 - Enable buzzer (0-Disabled/1-Enabled):
Allows enabling and disabling of the internal buzzer for alarm signaling.
F21 - Status of outputs with damaged sensor:
If a sensor short circuits, is turned off, or is off the measurement range, the output takes the status set in
this function.
[,,,0]
- Output off
[,,,1]
- Output on
[,,,2]
- Cycling according to times defined in
[,F22]
and
[,F23]
Note:
Function available for thermostat only, not valid for cyclic timer. If it is in heating and/or alarm
mode and/or has a malfunctioning sensor, the output will turn off.
F22 - Output-on time in the event of error:
F23 - Output-off time in the event of error:
These define the minimum time during which the output will remain on/off, respectively, if the sensor is
turned off, or is off the measurement range.
F24 - Minimum working voltage (protection):
F25 - Maximum working voltage (protection):
If the voltage value exceeds the limits set in these functions, the outputs will be turned off and the voltage
indicator LED will flash.
To disable voltage monitoring, set
[,F24]
greater than
[,F25]
.
F26- Time for voltage validation out of range:
This time prevents slight variations in voltage from abruptly exiting the outputs. The outputs will be
switched off after the voltage exceeds the limits of the working voltage and this time has elapsed. When
the voltage returns to acceptable levels, the outputs will be restarted after this time.
F27 - Voltage offset:
It compensates for possible deviations in the reading of the mains voltage.
F28- Preferred indication:
This function allows you to set the preferred measurement indication.
You can choose between:
[,,,0]
- Displays the temperature
[,,,1]
- Displays the voltage
[,,,2]
- Displays temperature and voltage alternately
Note:
If voltage monitoring is disabled, the preferred indication is only temperature.
