When the evaporator temperature (sensor S2) reaches the value configured by this
function, the controller will initiate the countdown to defrost.
When the evaporator temperature (sensor S2) drops and reaches the value set in
[d6]
,
[d7]
,
[d8]
, the countdown to start the pre-defrost begins. During this stage, if the
temperature remains low, the pre-defrost starts. Otherwise, if this temperature rises above
the set value, the system returns to the cooling stage.
When starting the defrosting process, the controller will only activate the fan to take
advantage of the gas' residual energy.
If the temperature on the evaporator (sensor S2) reaches the set value, the defrosting
process will end as it should, i.e. by temperature. Thus, it optimizes the defrosting process.
If the ambient temperature (sensor S1) reaches the set value, the defrosting process will
end by temperature.
If the controller is configured to perform defrosting by temperature, this time works as a
safeguard in situations where the evaporator temperature (sensor S2) does not reach the
programmed values in
[d6]
,
[d7]
,
[d8]
. This function determines the maximum time the
controller will wait without performing the defrost.
This function is used to set the maximum time for a defrosting process. If, within such
period, defrosting is not concluded by temperature, a dot will start blinking on the bottom-
right corner of the display (it needs to be enabled in
[A7]
), indicating that the defrosting
process has been concluded by the time limit rather than by temperature. This may happen
if the temperature set is too high, the time limit is too short, or the S2 sensor is disconnected
or not connected to the evaporator.
This function is intended to prevent a rise in ambient temperature, due to the defrosting
process, being displayed. During the defrosting process, the last measured temperature in
the cooling cycle will be frozen on the display. The indication will be unfrozen when this
temperature is re-reached or when the time set using this function is exceeded, after the
start of the next cooling cycle (whichever comes first). If set to the value
[,0]
, the
temperature display will only be frozen at the defrost stage. This function can be disabled if
set to
[no]
.
Allows a defrost to start when the controller is powered. For example, when the power
supply returns (in the case of a power shortage).
Time required for dripping, i.e. to drain the last drops of the evaporator. During this period,
all outputs remain turned off. If you do not want this stage, adjust this time to
[no]
.
The fan operation settings in normal and power-saving mode are:
[,A]
Automatic: The fan will be permanently switched on while the compressor is
activated. When the compressor is off, the fan will cycle according to the adjusted time to
[F3]
and
[F4]
.
[,C]
Continuous: The fan will be constantly activated.
[,d]
Dependent: The fan will be activated together with the compressor.
This is the amount of time the fan will remain ON if
[F1]
and
[F2]
are configured as
automatic, while the compressor is off.

The S2 sensor can be disabled. In this case, the defrost will be initiated in time.
This filter is intended to simulate an increase in mass on the ambient sensor (sensor S1),
thereby increasing its response time (thermal inertia). The higher the value set in this
function, the longer the response time of sensor S1. 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.
