46.2 RECOVERY ENABLED
If the temperature/pressure decreases under the set rC06-rC07 (differential) the recovery cycle, of the circuit detected by that
transducer , is enabled again.
46.3 NOTE ABOUT RECOVERY ENABLED/DISABLED
To avoid long period of time with recovery function disabled and the temperature/pressure within the range rC06-rC07, the units starts
counting the delay set in rC08. After this delay if the decreasing temperature is still within the rC06-rC07 range, the recovery cycle is
forced on again.
47. OPERATION RELATED TO THE REAL TIME CLOCK
47.1 Real Time Clock Disabled By Digital Input
When the digital input configured as “Operation working mode: by RTC or keyboard” is active, the real time
clock is disabled and all the function involved with the real time clock are disabled.
47.2 “Only supply fan” working mode”
This function can be enabled only if the Ichill is provided with internal clock.
If one of the digital input is configured as “Operation mode with supplay fan only” and it is activated, the Ichill
enables only the supply fan (other loads are disabled); the supplay fan works according to the time table
programming (parameters ES01..ES13).
ATTENTION:
When the supply fan is on and the Ichill is forced in STD-BY or remote OFF (by digital input), the supply fan
will be switched off with a CO18 delay.
48. MESSAGES - ALARM CODES
The alarm codes are defined by an alphanumeric code.
Alarm typology:
A
= alarm of the unit
b
= alarm of the circuit
C
= alarm of the compressor
48.1 Automatic / Manual Alarm Description
The menù ALARM allows to read the alarms.
An alarm can be:
automatic reset: the reset is automatic when the cause of the alarm is not present
manual reset: to reset the alarm see Cap. 39.2
Alarms managed by number of events per hour
Some alarms are managed by number of events per hour; when the alarm happens more times per hour the
alarm become a manual reset.
Following an example of low pressure alarm:
o
AL05=0
the alarm is always manual reset
o
0<AL05<16:
o
the alarm is automatic if the number of the event is < AL05
o
the alarm is manual if the number of the event is = AL05
o
AL05=16
the alarm is always automatic reset
Compressor overload alarm is always manual reset:
