oA1 First auxiliary relay configuration (7-8): ALL=
alarm;
Lig=
light;
AuS=
second thermostat;
tMr=
auxiliary
relay enabled by keyboard;
C2=
second compressor.
oA2 Second auxiliary relay configuration (1-2): ALL=
alarm;
Lig=
light;
AuS=
second thermostat;
tMr=
auxiliary relay enabled by keyboard;
C2=
second compressor.
oA3 Third auxiliary relay configuration (9-10): ALL=
alarm;
Lig=
light;
AuS=
second thermostat;
tMr=
auxiliary
relay enabled by keyboard;
C2=
second compressor.
14.5 SECOND RELAY MANAGEMENT
2CH Second compressor in holding mode:
if
oAi=C2
than the SET of the second compressor during cycles
is rS1,2,3 + OAS.

OAt Second compressor switching on delay:
time delay between the switching on of the first and second
compressor.
OAS Set point for second compressor:
temperature delta of the second compressor added to the set of
temperature control (rs1,2,3).
OAH Differential for second compressor:
(sempre
0) differenziale di temperature sul set del secondo
compressore.
OAi Second compressor probe: rP
=thermostat;
EP
=evaporator;
i1P
=insert probe 1;
i2P
=insert probe 2;
i3P
= insert probe 3.
14.6 AUXILIARY RELAY MANAGEMENT
OSt AUX output timer:
time in which the AUX output stays ON. It is used when
oA1
or
oA2
or
oA3=tMr
.
OSS Set point for AUX output, used when oA1 or oA2 or oA3=AUS.
OSH Differential for AUX output:
(always
0) intervention differential for the set point of the AUX output, with
OAH<0 the action is for heating, with OAH>0 it is for cooling.
OSi Probe selection for the second compressor: rP
=thermostat probe;
EP
=evaporator probe;
i1P
=insert
probe 1;
i2P
=insert probe 2;
i3P
=insert probe 3.
14.7 DEFROST
tdF Defrost type:
rE
= electrical heater;
in
= hot gas.
IdF Interval between defrost cycles:
determines the time interval between the beginnings of two defrost
cycles.
dtE Defrost termination temperature:
sets the temperature measured by the evaporator probe, which
terminates the defrost. Used only if
EPP=YES
.
MdF Maximum length for defrost:
when
EPP=no
(timed defrost) it sets the defrost duration, when
EPP=YES
(defrost termination based on temperature) it sets the maximum length for defrost. If
MdF=0
the defrost is
disabled.
dFd Temperature displayed during defrost:
rt
=real temperature;
it
=temperature at the start of defrost;
SEt
=set point;
dEF
=“dEF” message.
Fdt Drip time:
time intervals between reaching defrost termination temperature and the restoring of the
controllers' normal operation.
dAd
Defrost display time out:
sets the maximum time between the end of defrost and the restarting of the
real room temperature display.
14.8 FANS
FnC Fans operating mode during the holding phase:
o-n
=continuous mode, OFF during defrost;
C1n
=runs in parallel with the first compressor, OFF during defrost;
C2n
=runs in parallel with the second compressor, OFF during defrost;
Cn
=runs in parallel with compressors, OFF during defrost;
o-Y
=continuous mode, on during defrost;
C1y
=runs in parallel with the first compressor, on during defrost;
