HAL (!)
Maximum temperature alarm. Temperature value (intended either as distance from
Setpoint or as an absolute value based on Att) which, if exceeded in an upward direction,
triggers the activation of the alarm signal. See "Max/Min Temperature Alarms".

LAL (!)
Minimum temperature alarm. Temperature value (intended as distance from the set point
or as an absolute value based on Att) which, when exceeded downwards, triggers the
activation of the alarm signal. See "Max/Min Temperature Alarms".

ddL
Display mode during defrost.
0 = display the temperature read by Pb1;
1 = locks the reading on the temperature value read by Pb1 when defrosting starts, and
until the next time the SEt value is reached;
2 = displays the label deF during defrosting, and until the next time the SEt value is
reached.
0/1/2 num 1 1 1 1&2
dro
Select °C or °F for displaying the temperature read by probes. 0 = °C, 1 = °F.
NOTE: switching between °C and °F or vice-versa DOES NOT modify the SEt,
diF values, etc. (e.g. Setpoint=10°C becomes 10°F).
0/1 num 0 0 0 2
ddd
Selection of type of value to be displayed. 0 = Setpoint;

ddE
Selection of value to display on ECHO (ECPlus). 0 = Disabled (not present);
1 = probe Pb1; 2 = probe Pb2; 3 = not used; 4 = Setpoint.
0 ... 4 num 1 1 1 2
CONFIGURATION ('CnF' folder) - NOTE: the instrument must be switched off and then on again each time folder CnF parameter configuration is modified to prevent
any malfunction of the configuration and/or current timer operations.
H08
Stand-by operating mode.
0 = display switch off; the loads are active and the device reactivates the display to signal
any alarms;
1 = display switch off, loads and alarms stopped;
2 = display with OFF label, loads and alarms stopped.

± 7 = not used; ± 8 = deep cooling; ± 9 = not used; ±10 = not used.
NOTE: - the '+' sign indicates that the input is active if the contact is closed
- the '-' sign indicates that the input is active if the contact is open
