11. Defrost cycle termination
To access one of the parameters
displayed, press
and change
value using
or
. Confirm the
value by pressing
Term StP:
Defrost termination
setpoint (10 to 30bar - factory
setting: 20 bar)
Drying time:
Drying time (5 to 30
seconds - factory setting: 12s)
Max Defrost:
Maximum defrost time
(5 to 30 minutes - factory setting:
7 min)
Min cycle:
Minimum time between
defrost cycle (15 to 60min - factory
setting
:
25 min)
Note:
Dual circuits have two
independent refrigerant circuits.
Defrost cycle will only occur on the
circuit that needs it. The other circuit
will continue its normal operation if
required.
12. Compressor alarm
To access one of the parameters
displayed, press
and change
value using
or
. Confirm the
value by pressing
Compressor alarm:
Operating hours
for a warning (0 to 999000 hours by
1000 hours)
Setting compressor alarm at
000000 h will disable the
function.
Note:
Total operating hours =
compressor running hours + 3 x
compressor starts
