[,,11]Digital input: pressostat 2 status, contact NO
[,,12]Digital input: pressostat 2 status, contact NC
[,,13]Digital input: low pressure switch, contact NO
[,,14]Digital input: low pressure switch, contact NC
NOTE: When digital input is configurated as pressure switch, it allows turn off the compressor outputs,
fans and defrost, displaying the associated alarm to this alarm origin. When there are no longer
pressostat event, the controler returns to initial process configurated.
F59 - S2 Evaporator temperature indication offset:
It allows compensation for possible deviations in the evaporator temperature reading (S2) caused by
the replacement of the sensor or changes in the cable length. Sensor S2 can be switched off by
adjusting the function to the minimum value until the message[,OFF]is displayed. In this condition all
the functions that rely on the reading of sensor S2 will be disabled.
F60 - S3 sensor temperature indication offset:
It allows compensation for possible deviations in the S3 sensor temperature reading caused by the
replacement of the sensor or changes in the cable length. Sensor S3 can be switched off by adjusting
the function of the digital input 1 / Sensor S3 (F57) with the value [,OFF] (0) or making it to operate as
a digital input.
F61 - Intensity of the digital filter applied to sensor 1 (0 - deactivated):
This filter aims at simulating an increase of thermal mass on the sensor, thus increasing its response
time (thermal inertia). The higher the value adjusted in this function, the longer the response time of the
sensor.
F62 - Function lock:
It allows and configures the function lock (see item 6.3.8).
[,,,0]- Do not allow the function lock.
[,,,1]- Allow a partial lock where the control functions will be locked but the adjustment of the
setpoint is allowed.
[,,,2]- Allow full locking.
NOTE: The defrost and view of the minimum and maximum temperature records will always be
allowed.
F63 - Time for functions lockdown:
It configures the time in seconds for the command to activate the function lock.
[,,15]-[,,60] Time in seconds for the command to activate the lock.
F64 - Control functions shutdown:
Authorizes switching off the control functions (see item 6.3.9).
[no,,]Disables the control functions shutdown.
[,,,1]Enables activation/deactivation of the control functions only if the functions are unlocked.
[,,,2]Enables activation/deactivation of the control functions even if the functions are locked.
[,,,3]Enables activation/deactivation of the control functions only if the functions are unlocked.*
[,,,4]Enables activation/deactivation of the control functions even if the functions are locked.*
* When F64 is configured as 3 or 4 and the control functions shutdown is activated, the controller will
turn off the display, keeping only the indication light on. If any key is touched the display turns on by 5
seconds, turning off again until a new key is touched.
F65 - Operating mode of the room temperature alarms (S1):
Determines whether the values configured for the high room temperature (F07) and low room
temperature (F06) alarms are relative to the setpoint or absolute values.
[,,,0]- The room temperature alarms F06 and F07 represent values relative to the setpoint.
Example:
Desired temperature [SP,,]: - 5ºC
Low temperature alarm [,F06]: 2ºC
High temperature alarm[,F07]: 2ºC
Limits: ([SP,,]- [,F06] and [SP,,]+ [,F07]).
The low temperature alarm will be signaled at -7°C (-5-2) and the high temperature alarm at -3°C
(-5+2).
[,,,1]- the room temperature alarms F06 and F07 are absolute values.
Example:
Low temperature alarm [,F06]: -30ºC
High temperature alarm [,F07]: 15ºC
The low temperature alarm will be signaled at -30 °C and the high temperature alarm at 15 °C.
F66 - Maximum operating time of the COMP output for maintenance:
Whenever the COMP output is activated the controller will count its operating time. When the counted
time is equal or longer than the one set in this function, the display will show the message [AmaI], and
the audible warning will be activated if it is enabled (F56), meaning that the compressor must be
serviced.
NOTE: The value adjusted in this parameter will be multiplied by ten.
Example: Value adjusted = 1, then 1*10 = 10 hours for the next service.
F67 - Time to confirm a low evaporator (S2 / S3) temperature to start defrosting (if F45=1):
When the evaporator temperature drops and then reaches the value set in F47, the controller starts
counting the confirmation time to start defrosting. After the counting finishes, if the temperature is still
below the value configured in F47 the defrost is started. If the temperature is above the value
configured in F47 during the counting, the system continues at the refrigeration stage and the count is
reset to zero.
F68 - High pressure event validation time:
It is the minimum time that the pressure switch connected to the discharge line must remain activated in
order to be validated this event. This time is used to avoid unnecessary triggering due to the pressure
oscillation.
F69 - Low pressure event validation time:
It is the minimum time that the pressure switch connected to the suction line must remain on for
validated this event. This time is used to avoid unnecessary triggering due to oscillation of pressure.
F70 - Time to inhibit the reading of the low pressure when initializing:
Delay time that the suction line pressure switch takes to be within its ideal initialize the controller,
avoiding unwanted alarms.
F71 - Time to wait for control return after high pressure event:
After the high pressure event, the controller uses this timeout to then regain control.
F72 - Delay time to return to control after a low pressure event:
After the low pressure event, the controller uses this timeout to then regain control.

NOTE 1: For safety reasons, if controller registers 3 high pressure or 3 low pressure events in one hour
period, three outputs of controller will be turned OFF: Compressor, Defrost & Fan display on controller
will show alarm message [apHi] - High pressure alarm or [aplo] - Low pressure alarm. To reset
[apHi] and [aplo] alarms a manual intervention is required. To manually reset: short press
on controller to navigate [Hplp] option, short press
NOTE 2: The values set in F57 and F58 must be properly configured for digital inputs of high/low
pressure switches.
NOTE 3: The F71 and F72 times are independents of the time set in F10 - Minimum compressor time
ON.
F73 - Enable second defrost output:
With this function activated, you can make the output FAN operate as a second defrost output. This output
is activated during the execution of the pre-defrost, defrost and drainage.
NOTE: With these configurations, all the Fan features are disregarded, including the Fan Delay
process.
F74 - Enable preset SP2:
F75 - Enable preset SP3:
F76 - Enable preset SP4:

F86 - Datalogger operating mode:
It allows choosing one of the following datalogger operating modes:
[,,,0]- Always off
[,,,1]- Always on
[,,,2]- Manual operation
F87 - Sampling time (time between records in the memory):
It is the time in seconds for which the controller records samples of the temperature information, state
of the outputs, door status, and alarm status.
F88 - Minimum room temperature variation (S1) to force writing data to the memory:
The room temperature difference (S1) in relation to the last piece of data written in the datalogger for
the data to be recorded in the memory regardless of the sampling time set in F69. To deactivate this
function, just decrement the value until the message[,,no] is displayed.
F89 - Variation of the digital input or the outputs to force data writing:
It indicates whether changes in the digital input or in the control outputs will force data to be written in
the memory regardless of the sampling time set in F69.
[,,no]- Off
[,yes]- On
F90 - Overwrite old records when the memory is full?:
This function indicates whether the controller should start writing new data at the beginning of the
datalogger memory when the memory is full. This function prevents the last data calculated by the
equipment from being lost. If set to zero, when the datalogger memory is full the controller and Sitrad
will signal full memory.
