TEMPERATURE ALARMS PARAMETERS
P64
Temperature below which the minimum temperature alarm is
activated during post-chill storage, with relation to P7, i.e. "P7 +
P64" (with reference to the cabinet probe)
0
= no alarm
0
P65
Temperature above which the maximum temperature alarm is
activated during post-chill storage, with relation to P7, i.e. "P7 +
P65" (with reference to the cabinet probe)
0
= no alarm
0
P66
Temperature below which the minimum temperature alarm is
activated during post-freezing storage, with relation to P8, i.e.
"P8 + P66" (with reference to the cabinet probe)
0
= no alarm
0
P67
Temperature above which the maximum temperature alarm is
activated during post-freezing storage, with relation to P8, i.e.
"P8 + P67" (with reference to the cabinet probe)
0
= no alarm

NOTE:
(
1)
Altering parameter P0 effects all parameters where the unit of measurement is degrees
Celsius or degrees Fahrenheit
(2)
The unit of measurement depends on parameter P0
(3)
The test result is positive if the difference between the temperature measured by the needle
probe and the cabinet temperature is greater than the value set by parameter P14 at least 3
times out of 5 (checking is every 10 s); if the test result is negative a second test is initiated
(se parameter P15)
(4)
The result of the second test is positive if the difference between the temperature measured
by the needle probe and the cabinet temperature increases by at least 1_C/1_F with
respect to the previous check at least 6 times out of 8 (checking occurs every P15/8 s); if
parameter P15 is set to a value of less than 5 s, the second test will not be executed
(5)
If parameter P22 is set to 2, micro port input activation will not be signalled
(6
)
The unit of measurement depends on parameter P58
(7)
Defrosting will be activated on conclusion of the time which is greatest between those set
by parameters P30 and P31
(8)
If defrosting is requested when the compressor is on and the time set by parameter P30 is
less than the value set by parameter P31, the compressor will remain on and the solenoid
valve and defrosting will be activated after the time "P31 - P30" has elapsed since the
defrost request; vice versa, if defrosting is requested when the compressor is on and the
time set by parameter P30 is greater than that set by parameter P31, when defrosting is
