-
when blast chilling the evaporator fan is managed by parameter F0
-
for storage the evaporator fan is managed by parameter F2
-
when defrosting the evaporator fan is turned on.
With the chiller in stand-by only manual defrosting is possible; if the function
managed by relay K2 is the evaporator fan (parameter u0=1) the evaporator fan is
turned on and when dewatering this fan is turned off.
For manual defrosting:
•
check that no other cycle is running
•
press
for 4 seconds
When blast chilling deforesting is never activated.
When running a storage cycle defrosting is activated at set intervals; is possible to
activated defrosting in manual mode.

Compressor and evaporator fan conditions
To display information concerning the compressor:
check that no other cycle is running
• press
: the first available tag is displayed:
if “C-1” is displayed, the compressor is on
if “C-0” is displayed, the compressor is off
- if “C-P” is displayed, compressor protection is running (parameters C0, C1, C2 and
i7).
To display information concerning evaporator fan:
check that no other cycle is running
• press
twice: the first available tag is displayed:
if “F-1” is displayed, the evaporator fan is on
if “F-0” is displayed, the evaporator fan is off
if “F-P” is displayed, fan start up is delayed (parameter F8).
To escape this procedure:
• press
until the current chiller mode is displayed (refer to paragraph 2.2), or do
not use for 15 seconds.
If the function managed by relay K2 is defrosting (parameter
u0 = 0), tags “F-1”, “F-0” and “F-P” are not displayed.
