F06 - Control differential (Hysteresis) (
):
[Rc1,]
It is the difference in temperature (hysteresis) between TURNING ON and OFF the cooling (or heating)
when recipe (
[rc1,]
) is used.
Example:
One wants to control the temperature at 4.0 °C with a differential of 1.0 °C. Therefore, the
cooling is switched off at 4.0 °C and switched back on at 5.0 °C (4.0 + 1.0).
F07 - Cooling time (interval between defrosts) (
):
[Rc1,]
Corresponds to the time the controller will act on cooling when preset (
), is used; following this
[Rc1,]
period, the controller enters the natural defrost process.
F08 - Defrost time (
):
[Rc1,]
It is the defrost duration time when preset (
) is used. Within this period, the relay will remain off;
[Rc1,]
following this period, the controller will then return to the cooling state.
F09 - Operation setpoint (
):
[Rc2,]
It is the reference value for temperature control, that is, the temperature to be maintained in a controlled
environment when preset (
) is used.
[Rc2,]
F10 - Control differential (Hysteresis) (
[rc2,]
):
It is the difference in temperature (hysteresis) between TURNING ON and OFF the cooling (or heating)
when preset
(
[rc2,]
) is used.
Example:
One wants to control the temperature at 4.0 °C with a differential of 1.0 °C. Therefore, the
cooling is switched off at 4.0 °C and switched back on at 5.0 °C (4.0 + 1.0).
F11
- Cooling time (interval between defrosts) (
[rc2,]
):
Corresponds to the time the controller will act on cooling when recipe
(
[rc2,]
) is used; following this
period, the controller enters the natural defrost process.
F12
- Defrost time (
[rc2,]
):
It is the defrost duration time when preset (
[rc2,]
) is used. Within this period, the relay will remain off;
at the end of this period, the controller will return to the cooling state.
F13 - Minimum setpoint allowed to the end user:
Avoids regulation of excessively low setpoint temperatures by mistake.
F14 - Maximum setpoint allowed to the end user:
Avoids regulation of excessively high setpoint temperatures by mistake.
F15 - Minimum OUT1 output time on:
It is the minimum time the compressor will remain on, i.e. the time interval between the last start-up and
the next stop.
F16 - Minimum OUT1 output time off:
It is the minimum time the compressor will remain off, i.e. the time interval between the last stop and the
next start-up. It is used to relieve the discharge pressure and increase the service life of compressor.
F17 - Initial status when energizing the instrument:
It allows defrosting when controller is energized such as, for example, upon resuming of electric power
(in the event of power outage).
[,,,0]
- Cooling
[,,,1]
- Defrost
F18 - Temperature indication locked during defrost:
If
[,F18]
is enabled, the indication will only be released at the next cooling cycle after the temperature
reaches the “locked” value again, or after 15 minutes in cooling (as a safety measure).
F19 - Instrument energization delay:
This function being enabled, when the instrument is energized it only works as temperature indicator
remaining with the output off during the defined time. In installations with several units of equipment,
configuring different values for the delay time in the start-up of each instrument, it is possible to avoid
peaks of demand by activating the loads at different times.
This delay may be of the compressor or of defrost (when defrost is configured at the start).
Note:
At its end, the count of minimum time of output off is started, if there is any.
F20 - Compressor status with the sensor damaged:
If the sensor is in short-circuited, off or out of the measure range, the compressor assumes the set
status in this function.
[,,,0]
- Compressor off
[,,,1]
- Compressor on
[,,,2]
- Cycling according to times defined in
[,F21]
and
[,F22]
Note:
If in the heating mode, and in error, the output will be switched off.
F21 - Compressor time on in case of error:
F22 - Compressor time off in case of error:
These determine the minimum time the compressor will remain on/off, respectively, if the sensor is off or
out of the measure range.
F23 - Maximum Compressor on without reaching setpoint:
This is the maximum time the compressor may remain on without reaching the setpoint during the
cooling process for safety reasons. If this time is surpassed, the output is switched off and also the visual
alarm
[ALrC]
and the audible alarm (buzzer) will be activated. This function can be switched off by
setting it at the minimum value 0
[no,,]
.
N
o
te 1:
In this situation, the controller should be switched off and switched back on so as to continue
with the operation.
Note 2:
If the OUT2 output is set up to work differently from the alarm, this will also be switched off for
safety reasons.

F01 - Access code 123 (one hundred and twenty-three):
This is required when intending to change the configuration parameters. Entering of this code is not
required if the intention is just visualizing the parameters adjusted.
It allows entering of the expected access codes:
[,123]
- Allows access for changing the table parameters.
[,231]
- Allows configuring of the unit of measurement
[,=f,]
or
[,=C,]
.
[,231]
- To select the unit in which the instrument will operate enter the function
[,F01]
using the
access code
[,231]
then press the
/
key. Then, select the unit desired
[,=C,]
or
[,=F,]
using
the
< >
keys; to confirm press
/
.
or
Note:
Every time the unit is changed, the parameters should be reset, since they assume the ‘standard’
values of the parameter’s table.
F02 - Sensor indication displacement (offset):
Allows compensation for any temperature deviations from sensor replacement or change in the cable
length.
F03 - Using Presets:
Allows configuration of the controller so as whether or not to use the presets:
[no,,]
- No:
If configured this way, the instrument will not use the preset values in the control routines.
For this purpose, the setpoint
[SP,,]
will be used, adjusted via the quick access menu. The control
differential to be used shall be the same as in preset
[rc1,]
,
[,F06]
“OUT1 output control
differential (
[rc1,]
)”. The cooling time to be used shall be the same as in preset
[rc1,]
,
[,F07]
“OUT1 output cooling time (
[rc1,]
)”. Defrost time to be used will be the same as in preset 1,
[,F08]
“OUT1 output defrost time (
[rc1,]
)”.
The value configured in
[SP,,]
may be adjusted between
[,F13]
“Minimum setpoint allowed to the
end user” and
[,F14]
“Maximum setpoint allowed to the end user”.
In this configuration, the controller will not indicate which preset is enabled.
[yEs,]
- Yes:
Selection of presets will be made through the quick access menu, in the same way as for
adjusting the setpoint. In this configuration, the controller will indicate in the display which preset is
enabled,
[rc1,]
or
[rc2,]
. If configured this way, in the control routines the instrument will use the
values of setpoint, control differential, cooling time and defrost time configured in the parameters table.
F04 - Output operating mode OUT1:
Selects the out1 output operating mode:
[,,,0]
- Cooling
[,,,1]
- Heating
F05 - Operation setpoint (
):
[Rc1,]
It is the reference value for temperature control, that is, the temperature to be maintained in a controlled
environment when preset (
[rc1,]
) is used.
