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); in the heating mode the output turns 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 - Digital filter intensity applied to the sensor:
This filter has the purpose of simulating increase in thermal mass at the sensor thereby increasing its
response time (thermal inertia). The higher the value set in this function, the more time the sensor takes
to respond.
This function can be switched off by setting it at the minimum value 0
[no,,]
.
F25 - Functions Lockdown:
This enables and configures the functions lockdown:
[,,,0]
- Does not enable the functions lockdown.
[,,,1]
- Enables a partial lock where the control functions will be locked but the adjustment of the
setpoint, process times, cyclic timer times and visualization of the maximum and minimum record are
allowed.
[,,,2]
- Enables a total lock, only displaying the time of the cyclic timer and the record of maximum
and minimum temperatures.
F26 - Time for functions lockdown:
Allow lockdown of control functions (see item 8.3.2).
[,,15]
-
[,,60]
Defines the time in seconds for the controller to activate.
