[F100] - Temperature alarm validation time:
This function serves to inhibit the alarm for a period due to an eventual rise in temperature.
[F101] - Alarm inhibition time at power-up:
During this time the alarm remains off while waiting for the system to go back to an operating mode.
[F102] - Maximum time off compressor on whithout reaching the desired temperature
(setpoint):
The alarm is triggered if the compressor remains on without reaching the setpoint, for a longer time than
the length specified in this function.
[F103] - Maximum compressor operating time for maintenance alarm (hour meter):
Whenever the compressor (COMP or COMP VCC) is activated, the instrument will counts its operating
time. When the time counted is greater than or equal to the one set in this function, an alarm will be
generated indicating that maintenance on the compressor must be carried out.
[F104] - Trigger for alarm when defrosting is over based on time:
When the defrost cycle has been running for the length of time set, but has not reached the temperature
set, the user is notified via a decimal dot in the lower right corner of the display[,,,,* ] .
[F105] - Desired temperature for anti-condensation (sensor 3 heating setpoint):
It is the control temperature to avoid condensation of air humidity in the door. When the temperature of
the S3 sensor (door) is higher than the value configured in this function, the door resistance will be
turned off.
[F106] - Control differential for anti-condensation (S3):
It is the temperature difference between turning the door resistance off and on again to prevent
condensation.
[F107] - Enables audible alarm (buzzer):
Enables or disables the internal buzzer to sound alarms.
[F108] - High condenser temperature alarm (S3) (visual and audible only):
It is the condenser temperature above which the instrument will indicate visual [atC1] and audible
(buzzer) high temperature alarm. This alarm is ignored until the time configured in [F101] is
exceeded.
[F109] - Maximum condenser temperature (S3) to turn off control outputs:
Above this temperature, in addition to the visual alarm [atC2] and audible (buzzer) alarm indications,
the loads driven by the outputs will be switched off. This alarm is ignored until the time configured in
[F101] is exceeded.
[F110] - Control differential for maximum temperature in the condenser (hysteresis):
For the loads to be switched on again, the temperature of the S3 sensor (condenser) must drop to the
value set in [F109] minus the value set in this parameter. In this condition, the process moves to the
refrigeration stage.
[F111]- Time to confirm high pressure alarm:
It is the minimum time that the pressure switch connected to the discharge line must remain activated for
this event to be validated. This time serves to avoid unnecessary activations due to pressure
fluctuations.
[F112]- Time to confirm low pressure alarm:
F112 - Tempo de retardo inicial após partida do compressor para monitorar
It is the minimum time that the pressure switch connected to the suction line must remain activated for

Note 1: At the third event of high or low pressure, within a maximum interval of one hour when starting
up the controller, the system displays the message [aplo] - Low pressure switch alarm, which
requires the system to be manually reset. To do so, access the quick menu via the ;key, select
[Hplp] and short press the / key to select.
Note 2: Digital inputs must be configured as high/low pressure switches.
Note 3: The times of [F114] and [F115] are independent of the time set in [F67] - Minimum
time for compressor on.
[F116] - Minimum supply voltage (protection):
[F117] - Maximum supply voltage (protection):
If the voltage value exceeds the limits set in these functions, an alarm will be generated and the outputs
will be turned off.
To disable voltage monitoring, set [F116] greater than [F117].

Note 1: Voltage monitoring only applies to low voltage models (12 or 24Vac/dc) TC-970EL Log + Eco or
TC-970 EL Log + Eco Faston.
Note 2: When the instrument is being supplied with alternating voltage (Vac), the voltage calculated by
monitoring will be equivalent to direct voltage (Vdc).
[F118] - Voltage indication offset:
Allows you to compensate for possible deviations in the voltage reading.
[F119] - Voltage validation time:
This time prevents small voltage variations from prematurely turning off the outputs. The outputs will be
turned off after the voltage exceeds the working voltage limits and this time has elapsed.
When the voltage returns to acceptable levels, the output will be reconnected after this time has
elapsed.
[F120] - Enables recording of HACCP alarms:
Enables the recording of HACCP alarms as described in item 9.4.6.
[,,,0] - Disables;
[,,,1] – Enables.
[F121] - HACCP - Low temperature alarm:
It is the temperature above which the instrument will create a HACCP record of type [ALLo]as
described in item 9.4.6. This configuration is used only for HACCP records, it does not generate an
alarm on the alarm output and on the buzzer, as the values related to these specific alarms are
configured in their respective functions.
[F122] - HACCP - High temperature alarm:
It is the temperature above which the instrument will create a HACCP record of type
described in item 9.4.6. This configuration is used only for HACCP records, it does not generate an
alarm on the alarm output and on the buzzer, as the values related to these specific alarms are
configured in their respective functions.
[F123] - HACCP – Alarm inhibition time:
With this configuration active, the temperature will need to remain in the HACCP alarm condition for the
time defined in this function, in order for the alarm to be indicated. In this way it is possible to avoid alerts
from specific temperature variations. This setting is only used for HACCP records.
[F124] - Datalogger operating mode:
Allows you to choose between the following datalogger operating modes:
[,,,0] - Always off;
[,,,1] - Always on;
[,,,2] - Manual operation.
[F125] - Sampling period (time between records in memory):
Time in seconds that the controller will record a sampling of temperature information, output states, port
status and alarm status.
[F126] - Minimum temperature variation to force writing data to memory:
Temperature difference in relation to the last writing in the datalogger, so that the recording of data in
memory is forced regardless of the sampling time configured in [F125]. To deactivate this function,
simply decrease the value [Off,]is shown on the display.
[F127] - Variation of digital input or outputs to force writing of data:
Indicates wheter changing the digital input or control outputs will force data to be written to memory
regardless of the sampling time set in [F125].
[Off,] - Off;
[On,,] – On.
[F128] - Overwrite old records when memory is full?:
Indicates whether the controller should start writing new data at the beginning of the datalogger's
memory when it is full. This avoids losing the last data outputted by the equipment. If set to zero, when
the datalogger memory is full, the instrument and Sitrad will report full memory.
[F129] - Digital filter actuation mode:
[,,,0] : The digital filter acts in the visualization of the display and in the control routines;
[,,,1] : The digital filter acts only in the display view.
[F130] - Intensity of the digital filter on the room temperature sensor (S1 sensor) (Rising):
[F131] - Intensity of the digital filter on the room temperature sensor (S1 sensor)
(Descending):
The value adjusted in this function represents the time (in seconds) for the temperature to vary by 0.1ºC
/ 0.1ºF on rising or falling temperature.
Note: A typical use for this type of filter is in freezers for ice cream and frozen foods. When the door is
opened, a quantity of hot air will fall directly on the sensor, causing a rapid rise in the temperature
reading and, often, activating the compressor unnecessarily.
[F132] - Displacement of the values from the room temperature sensor (S1 sensor):
[F133] - Displacement of the values from the evaporator sensor (S2 sensor):
[F134] -Displacement auxiliary sensor indication displacement (S3 sensor):
[F135] - Displacement auxiliary sensor indication displacement (S4 sensor):
This allows you to compensate for possible deviations in the reading of the sensor, due to changing the
sensor or changing the cable length.
Note: Sensor S2 can be turned off by setting the indication offset to the minimum value until the
message [,OFF] appears. In this condition, all functions dependent on the S2 sensor reading stop
operating.
[F136] - Preferred indication on the display:
[,,,1] : S1 Temperature;
[,,,2] : S2 Temperature;
[,,,3] : S3 Temperature;
[,,,4] : S4 Temperature;
[,,,5] : Current setpoint.
Note: If the measurement is not available (e.g.: sensor deactivated), the message
displayed.
[F137] - Ambient temperature (S1 sensor) value locked in during defrosting:
[,,,0] : Sensor temperature indication;
[,,,1] : Reading locked in - last temperature before defrosting;
[,,,2] : Indication "[deFr]''.
This function is intended to prevent the display reflecting an increase in the room temperature due to
defrosting.
