‘AM’ = ‘AB’ or
‘RL’
Alarm Probe:
Func.
T1
T1
Air temperature probe used for alarm
detection
T2
Evaporator temperature probe used for
alarm detection (if ‘T2’ = ‘YS’).
T3
Third temperature probe used for alarm
detection (if ‘D2’ = ‘T3’).
AD
0 … 90min
Delay before alarm temperature warning
Min
90
AO
0 … 30min
Delay before door open alarm warning
(only when ‘D1’ or ‘D2’ = ‘DS’)
Min
5
PF
0 … 30°
Power failure alarm differential. (With
‘PF’ = ‘0’ power failure alarm is
disabled).
°K
10
AM
Operation in case of high condenser
alarm (if ‘D2’=‘T3’ and ‘T3’=‘CD’):
Func.
NO
NO
High condenser temperature alarm
inhibited
AP
Condenser warning – ‘HC’ displayed,
alarm sounds, operation continues.
ST
As ‘AP’ above, but compressor stopped
(R1 de-energised) and defrosts
suspended.
AS
-50 … 90°
Condenser alarm temperature (if ‘D2’ =
‘T3’).
°C
65
AF
Operation in case of high pressure
alarm (if ‘D2’ = ‘HP’):
Func.
ST
AP
Pressure warning – ‘HP’ displayed, alarm
sounds, operation continues.
ST
As ‘AP’ above, but compressor stopped
(R1 de-energised) and defrosts
suspended.
SA
All relays de-energised while condition
exists.
AC
0 … 52 wks.
Condenser cleaning period. (With ‘AC’ =
‘0’ condenser cleaning alarm is disabled)
Wks.
0
IIM
Switchover method to reduced
energy mode:
Func.
AU
NO
Reduced energy model is excluded (the
following parameter will be ‘DC’).
AU
Reduced energy mode is activated/ de-
active automatically via ‘IIS’ and ‘IIT’
D2
Second parameter set activated by ‘D2’
input (‘D2’ = ‘IIM’)
IIS
IIM = ‘AU’ or ‘D2’
1 … 90min
Minimum ‘non activity’ time for reduced
energy mode
Min
20
IIT
1 … 10°
Maximum temperature ‘addition’ for
reduced energy mode
°C
6
IIP
1 … 50°
Reduced energy mode temperature set
point – differential above ‘SP’
(refrigerating) below ‘SP’ (heating).
°K
2
IIY
1 … 10°
Reduced energy mode ‘off/on’
thermostat differential.
