‘DM’ = ‘TM’ or ‘FR’
Defrost display mode:
Func.
SP
RT
Real (actual) air temperature
LT
Last temperature display before start of
defrost
SP
The current set point value
DF
Display will show ‘dp’.

Fans in defrost:
Flag

YS
Fans run during defrost
NO
Fans do not run during defrost
FR
-50 … 90°
Evaporator fan restart temperature
following defrost. (Only if ‘T2’ = ‘1’).
°C

FS
0 … 90min
Maximum evaporator fan stop period
defrost (only when ‘T1’ = ‘1’).

FM
Evaporator fan mode during
thermostatic control:
Func.
TM
NO
Fan(s) run continuously (subject to door
& defrost).
TP
Temperature based control. When
compressor is on, fans are on.
TM
When compressor is off, fans run as long
as temperature difference Te-Ta > ‘FT’.
Fans on again with ‘FH’.
FT
-9.9 … 0°
Te-Ta difference for fans to turn off after
compressor stopped. (Only if ‘T2’ – ‘YS’
and ‘FM’ = ‘TM’)
°K
-1
FH
1 … 9.9°
Temperature differential for evaporator
fan restart (Only if ‘T2’ – ‘YS’ and ‘FM’ =
‘TM’)

F2
0 … 90sec
Timed fan stop following ‘F1’ (With F2 =
‘0’ the fans remain on all the time).
Sec

F3
0 … 90sec
Timed fan stop following ‘F2’ (With F3 =
‘0’ & F2 > 0 the fans remain off all the
time).

AT
Alarm threshold configuration:
Func.
RL
NO
All temperature alarms are inhibited
(the following parameter will be ‘AO’).
AB
The value set in ‘AL’ & ‘AH’ represent
actual alarm set points
RL
The values set in ‘AL’ & ‘AH’ are alarm
differentials which relate to ‘SP’ and ‘SP’
+ ‘HY’ (the following parameter will be
‘LD’)
AL
