9. Operating limits (cooling)
Low ambient temperature
limitation:
On: (factory setting) Low
ambiant limited
Off: Low ambient
temperature not limited
Low ambient limit: -20 to 20°C:
factory setting -10°C
Chilled water high limitation:
On: High water temperature
limited (factory setting)
Off: High water temperature
not limited
Chilled water high limit: 10 to 20 °C:
Factory setting 15°C
10. Defrost demand setpoint
Low ambient heating: -20 to 20°C,
factory setting -10°C
Setpoint at minimum ambient: 1 to
30°C, (factory setting 10°C)
Maximum ambient: -20 to 20°C:
(factory setting 12°C)
Setpoint at maximum ambient: 1 to
30°C, (factory setting 22°C)
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
Default parameters?: Set the default
parameters
Y: Reset all parameters
N: Keep all parameters
Note: When resetting, all parameters
programmed on site will be
definitively lost. Only factory default
set parameters will be kept. Full
configuration of the unit will have to
be checked.
