This is the control temperature of the normal operating mode. When the sensor S1
temperature (room) is lower than the configured value for this function, the compressor will
be turned off.
This is the control temperature when the power-saving mode is active. If the sensor S1
temperature (room) is lower than the configured value for this function, the compressor will
be turned off.
Limits preventing the accidental setup of an excessively high or low temperature setpoint,
which could result in high energy consumption by keeping the system turned on.
This is the difference between turning refrigeration OFF and BACK ON in normal operating
mode. Example: If adjusted [,f02]=[,,4.0] and [,f10]=[,,1.0], the compressor
will be turned off when the sensor S1 temperature (room) is less than [,,4.0]and it will be
turned on when it is higher than[,,5.0]([,,4.0]+ [,,1.0]).
This is the difference between turning refrigeration OFF and BACK ON in power-saving
mode.

The sensor S2 can be disabled. If this is the case, defrost will be initiated by time.
The value adjusted in this function represents the time (in seconds) for the temperature to
change by 0.1ºC. A typical application for this type of filter is for ice cream and frozen food
freezers, as, when the door is opened, a mass of hot air reaches the sensor directly, causing
a rapid increase in the measured temperature indication and often unnecessarily activating
the compressor.
This compensates for any deviations in the sensor reading due to replacement or a change
in cable length.

This is the value that will be added to the current preset setpoint after the time set in
[,f60].
Example: If [,f02]=[,,3.0](setpoint),[,f10]=[,,2.0](differential) and [,f16]
=[,,1.0](antifreeze), refrigeration will be turned off at [,,4.0]([,,3.0]+ [,,1.0])
and turned back on at[,,6.0]([,,3.0]+ [,,2.0]+[,,1.0]).

9.4 Parameters table
[,f01]
Access code: 123 (one hundred and twenty-three)
It is required for changing parameters. This code is not required for viewing the parameters.
It allows entering the access codes provided:
[,123]- Allows the access to change the parameters of the table.
[,231]- Allows configuring the units of measurement [,=f,] or [,=C,].
[,231]- To select the units the instrument will use to operate, enter function[,F01]
using the access code[,231], and then press/. Then select the desired unit [,=f,]
or [,=C,] using the<ou> key, and press /to confirm.
NOTE: Whenever the unit is changed the parameters must be reconfigured because they
will assume the "default" values of the table of parameters.

9.3 Functions lock
The use of the functions lock brings greater security to the operation of the instrument. When it is active,
the presets and other parameters can be visible to the user, but are protected against undue
changes([,f73]=2) or you can lock only the changes in the control functions and leave the selection
of presets unlocked ([,f73]=1). To lock the functions, access the option [LOC,] in the quick access
menu using the key (Flatec) and press to confirm. The message [no,,] will be displayed if the ; /
lock is inactive. At this time, press and hold the > key for the time configured in function [,f74]. The
activation will be indicated by the message [LOC,][On,,] and will take place only if
function[,f73] is configured with 1 or 2.

9.2 Control functions shutdown
When control functions are shutdown, the controller starts to operate purely as a temperature indicator,
with all outputs deactivated. How the operation of turning the control functions off is made shall depend
on the parameter “[,f75]- Control functions shutdown" setting:
[,,,0]Does not allow the control functions shutdown.
[,,,1]Allows the control functions to be turned on and off only if the functions are unlocked.
[,,,2]Allows the control functions to be turned on and off even if the functions are locked. With the
;key (quick touch), select [Ctrl], and then press /(quick touch) to confirm.
To deactivate the lock, switch the controller off and on again with the>key pressed. Keep the key
pressed until the message [LOC,][OFF,] is indicated.
