F39 - Fan cut off due to high temperature in the evaporator (S2 sensor):
This is intended to disconnect the evaporator fan when the room temperature is not within the design
range for the refrigeration device, avoiding high temperatures and suction pressures that could damage
the compressor. If the evaporator temperature exceeds the set value, the fan is turned off and will be
restarted at a fixed hysteresis of 2°C (3.6°F). This is a useful function to use when, for example, a
refrigerator is used that has been idle for days or when restocking units or counters with products.
F40 - Temperature in the evaporator to switch the fan back on after draining:
After drainage is complete, it starts a fan-delay cycle. The compressor will start up immediately,
because the temperature in the evaporator is high, but the fan will only start after the temperature in the
evaporator falls below the set value. This function is used to remove the heat that still exists in the
evaporator due to the defrost, avoiding throwing it into the environment.
F41 -Maximum length of time until the fan is switched back on after drainage (fan-delay):
For safety, if the temperature in the evaporator does not reach the value set by function
[F40]
or the S2
sensor is disconnected, the fan will only come on after the time set for this function has expired.

temperature (S1 sensor) is less than
[F32]
.

setpoint.
F47 - Maximum time in economy mode with closed door if
[,F42]
= 1 or 2:
Allows you to configure a maximum time for the economy mode to operate while the door is closed. After
this time, the setpoint returns to economy mode in normal operation.
F48 - Minimum variable compressor on time:
This is the minimum amount of time the compressor will be on, i.e. The period of time between the last
section and the next time it is stopped. This helps to avoid power surges from the electricity grid.
F49 - Minimum time of variable compressor off:
This is the minimum amount of time the compressor will be off, i.e. The period of time between the last

After reaching the temperature setpoint, it is possible to keep the compressor running at a speed
calculated by the PID control algorithm. The purpose is to avoid successive starts of the compressor,
obtaining a reduction in energy consumption (energy efficiency) as well as low oscillation of the room
temperature (sensor S1).
If set to

setpoint. If set to

In case the temperature reaches the low temperature limit

differential for the setpoint is adjusted.

(
