Defrost control
Defrost start
Defrost will start if:
• The time programmed in parameter d0 has elapsed since the start of the last defrost.
• Press the
H
key for 3 seconds.
• By means of an external push-button (I10 / I11=5).
• Through the app or through AKONet.
Defrost completion
Defrost will complete if:
• The temperature programmed in parameter d4 has been reached in sensor 2. This requires a 2 nd sensor (l00=2)
to be available, located in the evaporator.
• The time configured in parameter d1 has elapsed (maximum defrost duration).
• Press the
H key for 5 seconds.
• By means of an external push-button (I10/I20=5).
• Through the app or through AKONet.
Drip time
It is set by parameter d9 and defines the time added at the end of defrost to allow the evacuation of the remaining
defrost water from the evaporator, during which time there is no cooling regulation.
Fan start-up delay
This is established through parameter F4 and allows for the possible drops left in the evaporator to freeze before the
fans activate, preventing them from being projected into the cold room. It also prevents heat being supplied to the
cold room due to defrost in the evaporator.
If defrost is cancelled before 1 minute has elapsed, the drip time (d9) is not applied and the fans are
activated without taking into account the start-up delay (F4).
If defrost is by air or is static, the drip time (d9) and fan start-up delay (F4) are deactivated.
Message displayed during defrost
This is established using parameter d2, and you can choose between displaying the real temperature captured by
sensor 1 (d2=0), showing the temperature captured by sensor 1 at the start of the defrost (d2=1), or displaying the
dEF (d2=2) message. Parameter d3 defines the time during which the aforementioned message will be displayed
once the drip time (d9) and fan stop time (F4) are complete.
