Read the duration of the ongoing defrost or the dura-
tion of the last completed defrost.
Command for starting a defrost
Command for stopping an ongoing defrost cycle
0=None, 1=Electrical, 4=Air/Ocycle
Here you dene whether a defrost cycle is to be stop-
ped by time or by a temperature sensor
0=Time, 1=S5 sensor, 2=S4 sensor
When the selected defrost stop sensor reaches the set
limit, the defrost cycle is terminated
Defrost stop temperature limit when thermostat band
2 is in operation.When the selected defrost stop sen-
sor reaches the set limit, the defrost cycle is termina-
ted
Minimum duration of a defrost cycle. The defrost cy-
cle will as a minimum run for the set minimum defrost
time once it is started
Max duration of a defrost cycle. The setting is also
used as a safety time if the defrost is stopped on tem-
perature. If the selected defrost stop sensor does not
reach the set defrost stop temperature limit within
the set time, the defrost will be stopped anyway.
Max duration of a defrost cycle when thermostat
band 2 is in operation. The setting is also used as a
safety time if the defrost is stopped on temperature. If
the selected defrost stop sensor does not reach the
set defrost stop temperature limit within the set time,
the defrost will be stopped anyway.
The function is zeroset and will start the timer func-
tion at each defrost start. When the time has expired
the function will start a defrost. The function is used
as a simple defrost start, or it may be used as a safe-
guard if the normal signal fails to appear. If master/
slave defrost without clock function or without data
communication is used, the interval time will be used
as max. time between defrosts. If a defrost start via
data communcation does not take place, the interval
time will be used as max. time between de-
frosts.When there is defrost with clock function or da-
ta communication, the interval time must be set for a
somewhat longer period of time than the planned
one. In connection with power failure the interval
time will be maintained, and when the power returns
the interval time will continue from the maintained
value. he interval time is not active when set to 0
Time staggering for defrost cut-ins during start-up
The function is only relevant if you have several refrig-
eration appliances or groups where you want the de-
frost to be staggered in relation to one another. The
function is furthermore only relevant if you have
chosen defrost with interval start. The function delays
the interval time by the set number of minutes, but it
only does it once, and this at the very rst defrost tak-
ing place when voltage is connected to the controller.
The function will be active after each and every pow-
er failure.
Defrost on demand. Aggregate refrigeration time set
here is the refrigeration time allowed without de-
frosts. If the time is passed, a defrost will be started.
With setting = 0 the function is not in use.
Set the time where the evaporator is emptied of re-
frigerant prior to the actual defrost cycle
Here you set the time that is to elapse from a defrost
and until the compressor is to start again. (The time
when water drips o the evaporator).
Max. standby time after coordinated defrost. When a
controller has completed a defrost it will wait for a
signal tellingthat the refrigeration may be resumed. If
this signal fails to appear for one reason or another,
the controller itself will start the refrigeration when
the standby time has elapsed.
