With the door closed, this parameter defines how much time to active economic mode. On
the economy mode the light output will be disabled and the operation setpoint will be
changed to the economy setpoint.
This time only starts counting after the temperature reaches the setpoint for the first time.
Note:
Scale hours.minutes - time less than 10.0 displays decimal point. Ex: value 1.5
corresponds to 1 hour and 30 minutes.
Allows you to configure a maximum power save mode actuation time while the door is
closed. After this time, the setpoint returns to normal operating mode. This time is
calculated in hours.
Note:
Scale hours.minutes - time less than 10.0 displays decimal point. Ex: value 1.5
corresponds to 1 hour and 30 minutes.
Shuts down the evaporator fan if the evaporator temperature is equal or higher than this
temperature. During operation if the evaporator temperature exceeds the configured value,
the fan is turned OFF, and only restarts with 2°C (4°F) differential. It is a valuable resource
when, for example, cooling equipment has been inactive for a few days or when freezer
rooms or refrigerated counters are refilled with stock.
Evaporator high temperature fan shutdown
Evaporator temperature for fan reactivation after
drainage
After defrost and drainage, the fan delay cycle starts. The compressor is started
immediately because the evaporator temperature is high, but the fan will only be started
after the evaporator temperature drops from the configured value. This function is used to
remove the heat that still exists in the evaporator because of the defrost, avoiding putting it
into the environment.
For safety, if the evaporator temperature does not reach the value set in the function
[F6]
or the sensor S2 is disconnected, the fan will return after the time configured in this function.

Unit of time applied to door closed time to turn

Door closed time to turn off the light
Door closed time to enable for economy mode
This is the minimum time the compressor will remain on, i.e. the time between the last start
and the next stop. It serves to prevent short cycle and high voltage surges.
Minimum time of the compressor turned on
This is the minimum time the compressor will remain off, i.e. the time between the last stop
and the next start. It serves to relieve the discharge pressure and increase the service life of
the compressor.

Note 1
: With sensor S2 enabled, modes 0 and 1 will activate the fun only if the evaporator
temperature (sensor S2) is lower than cabinet temperature (sensor S1).

Maximum defrost time (for safety)
This function configures the maximum defrost duration time. If, within this period, the
defrost is not ended by temperature, a dot will flash on the lower right corner of the display (if
enabled in
), indicating that defrost termination occurred by time rather than
[A8]
temperature. This can happen when the temperature configured is too high, the time limit is
insufficient, sensor S2 is disconnected or it is not in contact with the evaporator.
