[F00] - Controller operating mode:
[,,,0] – Refrigeration / Cooling
The compressor turns off when the temperature of sensor S1 (room temperature) is less than or equal
to the Setpoint and restarts when the temperature of sensor S1 is equal to the (Setpoint + Differential of
control in refrigeration).
[,,,1] – Heating
The compressor turns off when the temperature of sensor S1 (room temperature) is greater than or
equal to the Setpoint and restarts when the temperature of sensor S1 is equal to the (Setpoint - Heating
control differential)

[,,,2] – Automatic
In this operating mode, the AUX output is configured for cycle reversing valve and it is not possible to
change its value.
If cooling is active (AUX relay off)
The compressor turns off when the temperature of sensor S1 (room temperature) is less than or equal
to the Setpoint and restarts when the temperature of sensor S1 is equal to the (Setpoint + Differential of
control in refrigeration).
If the temperature drops to (Setpoint - Heating control differential), the cycle is reversed and the
controller starts to control the temperature by heating the room. At this time the AUX relay is turned on.
If heating is active (AUX relay on)
The compressor turns off when the temperature of sensor S1 (room temperature) is greater than or
equal to the Setpoint and restarts when the temperature of sensor S1 is equal to the (Setpoint - Heating
control differential).
If the temperature increases to (Setpoint + Control differential in cooling), the cycle is inverted and the
controller starts to control the temperature, cooling the environment . At this time the AUX relay is turned
off.
[F01] - Desired temperature (setpoint):
It is the control temperature of the normal operating mode, that is, it is the temperature that you wan to
maintain in the controlled environment.
[F02] -Desired temperature (economic setpoint):
It is the control temperature when the economy operating mode is on.
[F03] - Minimum desired temperature (setpoint) allowed to the user:
[F04] - Maximum desired temperature (setpoint) allowed to the user:
Limits set in order to avoid execessively high or low temperatures being accidentally set for the
temperature setpoint, which could lead to high energy consumption by keeping the system on
continuously.
[F05] - Operating setpoint control differential (cooling):
[F06] - Economic setpoint control differential (cooling):
It is the temperature difference between turning the cooling off and on again.
[F07] - Operating setpoint control differential (heating):
[F08] - Economic setpoint control differential (heating):
it is the temperature difference between turning the heating OFF and ON.
[F09] - Time for Economic Mode to begin (Monday to Friday):
Time when the economic setpoint [SP-E] will be activated on working days.
This function can be turned off by setting it to the maximum value [Off,].
[F10] - Time for Economic Mode to begin (Saturday):
Time when the economic setpoint [SP-E] will be activated on Saturdays.
This function can be turned off by setting it to the maximum value
[F11]- Time for Economic Mode to begin (Sunday):
Time when the economic setpoint [SP-E] will be activated on Sundays.
This function can be turned off by setting it to the maximum value [Off,].
[F12] - Temperature difference (S3-S1) below which the economic setpoint is activated:
When the temperature difference between sensor 3 and sensor 1 is less than the value set in this
parameter, the controller starts to operate in economy mode.
[F13] - Temperature difference (S3-S1) above which the normal setpoint is activated:
When the temperature difference between sensor 3 and sensor 1 is greater than the value set in this
parameter, the controller starts to operate with normal setpoint.
[F14] - Maximum temperature in economic mode:
Allows you to set the maximum length of time economy mode will operate for. After this time, the setpoint
returns to economy mode in normal operation. If this is set to [OFF,] this time will be ignored.
[F15] - Fast Freezing temperature limit:
This is the minimum temperature that the instrument can reach during the Fast Freezing process.
[F16] - Maximum Fast Freezing time:
This the duration of the Fast Freezing process.
[F17] - Delay time when powering up the controller:
When the instrument is turned on, it can remain disabled for a while, delaying the start of the process.
During this time it only works as a temperature gauge. Helps to avoid high demands for power, when
power returns after a power cut, where several pieces of equipment are all on the same connection.
Therefore, you can set different times for each device. This delay can relate to the compressor or
defrosting (where defrosting is part of the sequence).
[F18]- Defrost type:
[,,,0] - Electrical Defrosting (using coils), which only applies to the defrost outlet;
[,,,1]- Hot gas Defrosting, which only applies to the compressor and defrosting outlets;
[,,,2] - Natural defrosting, which only applies to the fan outlet.

F19 - Condition for starting defrosting:
[OFF,] – No automatic defrosting, only manual defrosting;
[,,,1] – Defrost initiated by time;
[,,,2] – Defrost initiated by temperature;
[,,,3] – Set temperature difference (S1-S2) to start defrosting;
[,,,4] – Set temperature and temperature difference (S1-S2) to start defrosting;
[,,,5] – Defrost schedule.
[F20] - Interval between defrosts (cooling) if [F19] = 1 or Maximum time without defrosts
(cooling) if [F19] = 2, 3 or 4:
[F21] - Interval between defrosts (heating) if [F19] = 1 or Maximum time without defrosts
(heating) if [F19] = 2, 3 or 4:
Setpoint
It determines how often and after how long defrosting. If the controller is configured to perform defrost
Setpoint + Hysteresis
by temperature ([F19] = 2, 3 or 4), this time acts as a safety measure in situations where the
evaporator temperature (sensor S2) does not reach the values programmed in [F23] or [F24].
Time [S]
This function determines the maximum time that the controller will wait before carrying out defrosting.
[F22] - Additional time at the end of the first refrigeration cycle:
This is to set a longer period of time for the first refrigeration cycle. Where there are setups with several
pieces of equipment, you can avoid high demand peaks by ensuring that defrosting takes place at
different times by assigning different values to this function.
[F23] - Temperature of the evaporator (S2 sensor) in order to begin defrosting if [F19]=2, 3 or
4:
When the evaporator temperature is lower than the value set in this function, the controller will start
defrosting. If sensor S3 is configured as a second evaporator sensor, the controller will start defrosting
as soon as one of the two sensors, S2 or S3, meets this condition.
[F24] - Temperature Difference in order to start defrosting (S1 - S2) if [F19] = 3 or 4:
When the difference between the temperature of the room sensor (S1 sensor) and the temperature of
the evaporator (S2 sensor) reaches a value using this function, the controller will wait for the length of
time before beginning defrosting.
[F25] - Time to confirm the lower temperature (sensor S2 / S3) to start the pre-defrost [F19] =
2, 3 or 4:
If the controller is configured to defrost according to temperature, the moment the temperature reaches
the set value, it will run a delay before starting the pre-defrost stage.
If the temperature remains low, while this stage is running, the pre-defrost process is started. If it
doesn't and the temperature rises above the set value, the system will return to a refrigeration cycle.
[F26] - Defrost when the controller is powered on:
This enables a defrosting to be conducted when the controller is powered on. For example, when the
electricity returns after a power cut.
[F27] - Smooth Defrost if F18 = 0:
Smooth Defrost mode provides a smoother defrosting, saving energy and preventing the room
temperature from rising as much as in a standard defrost. In this mode, the defrost output remains on
as long as the evaporator temperature (S2 sensor) is less than 2°C (35.6°F) and, after passing that
temperature, the output remains on for the percentage of time configured in this function, within a 2
minute period.
[F28] - Number of defrots per day (Monday to Friday) if [F19] = 5:
The defrosts are distributed at equal intervals according to the programming of the number of defrosts
per day, always considering the preferred time, being able to adjust the values in 1, 2, 3, 4, 6, 8 or 12.
Monday to Friday.
[F29] - Time to start defrost (Monday) if [F19] = 5:
[F30] - Time to start defrost (Tuesday) if [F19] = 5:
[F31] - Time to start defrost (Wednesday) if [F19] = 5:
[F32] - Time to start defrost (Thursday) if [F19] = 5:
[F33] - Time to start defrost (Friday) if [F19] = 5
Enables the preferred start time of one of the daily defrost cycles to be adjusted.
This function is to program this for Monday to Friday.
[F34] - Number of Defrostings per day (Saturday) if [F19] = 5:
Defrosting is set to take place at equal intervals according to the number programmed per day, always
taking preferred times into account. It can be adjusted using values of 1, 2, 3, 4, 6, 8 or 12.
This function is to program this for Saturday.
[F35] - Time to start defrost (Saturday) if [F19] = 5:
Enables the preferred start time of one of the daily defrost cycles to be adjusted.
This function is to program this for Saturday.
[F36] - Number of Defrostings per day (Sunday) if [F19] = 5:
Defrosting is set to take place at equal intervals according to the number programmed per day, always
taking preferred times into account. It can be adjusted using values of 1, 2, 3, 4, 6, 8 or 12. This function
is to program this for Sunday.
[F37]- Time to start Defrost (Sunday) if [F19] = 5:
Enables the preferred start time of one of the daily defrost cycles to be adjusted.
This function is to program this for Sunday.
[F38]- Length of pre-defrost (collecting in gas):
When the defrost starts, the controller will only use the fan during this time, in order to take advantage of
the residual energy of the gas.
[F39]- Evaporator temperature (sensor S2 / S3) to end defrost:
In the temperature in the evaporator reaches the set value, the end of defrost will take place as desired,
that is, by temperature. This way it improves the defrosting process. If sensor S3 is configured as the
second evaporator sensor, the controller will turn off the defrost outputs individually and the defrost
process will be terminated when both are turned off.
[F40] - Temperature of the Ambient Sensor (S1 sensor) to finish the defrost:
If the room temperature (sensor S1) reaches the set value, the defrost cycle will be halted due to
temperature.
