AU1 Auxiliary/alarm relay 1 control
AU2 Auxiliary/alarm relay 2 control
Temperature setting for auxiliary relay
StA
nSC Correction factor for the SET button during night
operation (energy saving)
(with In1 or In2 = 8 or -8)
During night operation the control set is:
Set Control = Set + nSC
In night mode decimal point flashes.
In1 INP-1 input setting
-6 (NC) = relay de-energised
during stand-by
-5 (NC) = Contact for casing
element control (AUX
relay closed with
compressor output
inactive).
-4 (NC) = pump down function
(NC, see CHAP 5.16)
-3 (NC) = automatic auxiliary
relay managed by StA
temp. setting with 2°C
differential (NC)
-2 (NC) = manual auxiliary relay
controlled via AUX key
(NC)
-1 (NC) = alarm relay (NC)
0 = relay deactivated
1 (NO) = alarm relay (NO)
2 (NO) =manual auxiliary relay
controlled via AUX key
(NO)
3 (NO) = automatic auxiliary
relay managed by StA
temp. setting with 2°C
differential (NO)
4 (NO) = pump down function
(NO, see CHAP 5.16)
5 (NO) = free voltage contact for
condensing unit (AUX
relay and compressor
relay in parallel)
6 (NO) = relay excited during
stand-by
(like AU1 )
-45 – 45 °C
-20 – 20 °C
8 = Night mode digital input
(energy saving, N.O.)
7 = Stop defrosting remotely (N.O.)
(reads rising edge of impulse)
6 = Start defrosting remotely (N.O.)
(reads rising edge of impulse)
5 = Stand-by remotely (N.O.) (In
order to indicate Stand-By
mode, the display shows 'In5'
alternating with the current
view)
4 = Pump-down pressure switch
(N.O.)
3 = Man-in-room alarm (N.O.)
2 = Compressor protection (N.O.)
1 = Door switch (N.O.)
0 = disabled
-1 = Door switch (N.C.)
-2 = Compressor protection (N.C.)
-3 = Man-in-room alarm (N.C.)
-4 = Pump-down pressure switch
(N.C.)
-5 = Stand-by remotely (N.C.) (In
order to indicate Stand-By
mode, the display shows 'In5'
alternating with the current
view)
-6 = Start defrosting remotely (N.C.)
(reads falling edge of impulse)
-7 = Stop defrosting remotely (N.C.)
(reads falling edge of impulse)
-8 = Night mode digital input
(energy saving, N.C.)
