0: direct alarm
Zero current principle, direct alarm
on loss of current at the input
1: delayed alarm
Zero current principle, delayed alarm
on loss of current at the input
setting of delay time with P44
2: external defrost trigger
start of defrost either by button
or an external defrost timer
3: Cold location off
Control, temperature monitoring and probe monitoring
inactive, alarms are suppressed,
communication remains active, no messages via remote
data transmission
P51 Status
input 1

Voltage status at digital input 1
(independent of selected function)
P52
Digital
input 2
0 0 2 0: Door contact
When the cold room is entered, fan and
evaporator solenoid switch off for a maximum of 15 mins.
Alarm after alarm delay
1: Day signal
Signals day operation,
set value shift for night operation
2: Shock freeze
The desired sharp freezing temperature is preset via P14. It
is controlled on the sharp setpoint. After the function is
ended and the sharp temperature is reached, forced
defrosting is performed; only when this is completed does
the device return to normal operation. During sharp
freezing, defrosting is not started.
3: Cooler off
Control, temperature monitoring and probe monitoring
inactive, alarms are suppressed,
communication remains active, no messages via remote
data transmission
4: 2

setpoint
Control to the 2nd setpoint The 2nd setpoint is preset via
P14 (sharp set value).
